Water immersion[edit]

Article says "Hypothermia continues to be a major limitation to swimming or diving in cold water."

That's a pretty dumb sentence and if you don't know why... then maybe you should've been a doctor. — Preceding unsigned comment added by (talk) 12:30, 12 February 2016 (UTC)

Its pretty obnoxious to point out a "mistake" and then put a snide insult where an explanation should be.

Worse still, it makes perfect sense. Hypothermia limits how long you can spend in cold water. Perfect sense. And to add icing to the cake: if (from your perspective) the writer *doesn't* know why that sentence is "dumb", why would you want him to be a doctor?! (talk) 08:52, 12 July 2016 (UTC)


This page gives medical advice, which is explicitly discouraged (see Wikipedia:What wikipedia is not). It should be altered to a more encyclopedic style, telling the reader what is done, not how to do it. --Delldot 23:59, 4 November 2005 (UTC)

Agreed. Some of the medical "advice" is decidedly dodgy anyway (such as giving warm drinks). I'll edit it later, unless anybody has objections? --John24601 16:12, 7 January 2006 (UTC)
I agree that the page shouldn't say "do this", but if the content can be sourced, I do think that it is can be appropriate for it to state that "the so-and-so organization recommends the following procedures." --Arcadian 16:47, 7 January 2006 (UTC)
Maybe it would be better to talk about the principles of treatment (such as slow rewarming), without going into specifics of "do this"? --John24601 17:02, 7 January 2006 (UTC)
I agree, alot of it is dodgy and I have tried my best to remove and disclaimer anything that is too risky, the whole warm water thing does nothing but make them feel warmer, removing the subject from the elements is the best thing anyone can do until aid arrives.TheHye
Since Wikipedia's guidelines discourage giving medical advice and prscriptions, some of the first aid pointers are questionable anyway, I have deleted some of the material and relocated the more pertinent points (such as alcohol consumption being a risk factor). As a result I also removed the "How To" tag which had been placed on the page. Wildernessflyfisher 23:46, 9 October 2007 (UTC)

Casualty vs Subject[edit]

Some anonymous user changed the word "casualty" to "subject"... is it just me, or is casualty a far more appropriate term to refer to someone with this condition? --John24601 16:52, 17 January 2006 (UTC)

(Referencing this edit) I agree that casualty is a better term, but we should probably wikify it to Casualty (person), which addresses the ambiguity in the term (which is probably why the anon changed it.) --Arcadian 17:02, 17 January 2006 (UTC)
How about patient then? Although that is currently not in favour with the powers that be in the brittish health service, we are encouraged to call our patients "clients" or "customers" *rolleyes* --John24601 18:03, 17 January 2006 (UTC)
I've got no problems with that. We've got an article for Patient that already includes the phrase "Health consumer or health care consumer is another name for patient." I've added links on Casualty (person) and Patient so each now references the other. I think either of those terms would be much better than Subject. --Arcadian 18:32, 17 January 2006 (UTC)

I changed the text from casualty to subject, because in the Search and Rescue community (at least in Washington State) that is the standard name we give anyone we are assisting. Calling a person a subject (a neutral name) is much less degrading than calling them casualties or patients.TheHye 22:50, 3 May 2006 (UTC)

I've had hypothermia 3 times, and have a pamphlet about it. It's essential to prevent "core-temperature afterdrop." Do this by adding heat to a spot over a vein, or warm air into the lungs. Mouth-to-mouth rescusitation has been used for this. The wrist is a good spot to add heat. 05:12, 14 April 2007 (UTC) Jean SmilingCoyote, 4/14/07
Bullshit! As an EMT I hate these lunatic rumors. First: almost everyone outside a city doing physichal work has had a hypothermia, mostly mild. Normally, it is not a big deal, although it feels like shit afterwards. Second: Warming wrists? In hypothermia blood _does not_ circulate in extremeties!

A swift death[edit]

How can you possibly die from acute hypothermia in seconds? I suppose being submerged in liquid nitrogen would bring a swift death, but I doubt the actual cause would then be hypothermia. In either case, there are surely no natural environments that would not at least take several minutes to kill a person, and thus I believe the wording "seconds or" should be removed. Maggu 12:04, 17 February 2006 (UTC)

Agreed. I think the point that the editor who wrote this is trying to make, however, is that cardiac arrest occurs within seconds/minutes. If left untreated, this is effectively death, but all the research suggests that a period of several hours may occur between such a cardiac arrest hapenning and it being successfuly treated. I think it all really depends on your definition of death, and whether we're talking about a natural process of events or one in which resuscitative efforts are made... --John24601 20:07, 17 February 2006 (UTC)
I am not a health professional but I have some experience of low temperature, and I doubt a young and healthy person could suffer cardiac arrest within seconds from being in a (naturally) cold environment. Even at -40 it takes a while for the body to cool down. Anyway, I see no objections so I'm editing the article. --Maggu 13:54, 27 February 2006 (UTC)
Well, I suspect this is talking about a cold shock response rather than hypothermia, so this would be a sudden exposure to cold - so suddenly falling through ice, or falling into deep, cold water on a hot day, triggering a cardiac arrest. Average Earthman 20:11, 18 March 2006 (UTC)
Hypothermia can occur at 50 degrees Fahrenheit, so don't fool yourself into thinking that it needs to be extremely cold to even have to consider it as a threat. Depending on temps you could die of hypothermia in less than 3 hours.TheHye 23:03, 3 May 2006 (UTC)

Cold water shock can cause very quick death, if a person dives or jumps into the water and submerses his/her head in the process. The cold shock can cause an involuntary gasping inhalation, and if the person's head is underwater, that is an inspiration of water. This can lead extremely quickly to drowning. The way to prevent this is to get into the water feet-first, and not let the person's head go underwater. Rescue is still possible, and the person can still be viable for an hour (recorded by cold-water near drowning incidents), but the person will be unable to help him/herself, and rescue must be quick. Complications of inhaling salt- or freshwater need to be attended to, and so even if the person is brought back by the rescue, he/she must see a physician in a hospital to overcome the long-term effects of drowning.--John C. Ratliff 00:12, 12 December 2006 (UTC)

All true, but this is not hypothermia. -- Mwanner | Talk 12:06, 22 April 2008 (UTC)


The page uses US units of measurement, which are of limited use to a global audience. Therefore I have tagged the page with the Metricate template.

When converting the units:

  • If possible, use information from the original references.
  • Do not convert them yourself without checking them first. The units themselves may have been converted from SI units for the article, and converting them back again may lead to loss of accuracy.
  • For Wikipedia users who still use US units, it may be helpful to retain these units of measurement in the article in parentheses after the metric measurement. Example: 0°C (32°F).

Stages of Hypothermia in Humans[edit]

I have removed medical advice from this section, because Wikipedia is not a place for medical advice. Here is the removed text, if anyone is interested:

  • Do not rub or massage the patient
  • Do not give alcohol
  • Do not give food or drink (this includes warm drinks, this is only in extreme cases. The reason being that blood is diverted from the major organs where it is needed, and is sent to the stomach and intestines to digest the food/liquid, therefore lowering the core temperature further.)
  • Do not allow the body to become vertical
  • Move the patient with care. If the patient is moved too much, fatal cardiac arrythmias such as V-fib could be triggered.

Any of these actions will divert blood from the critical internal organs and may make the situation worse.

What you should do...

  • Call the emergency services.
  • Get the patient to shelter.
  • If possible, put the patient in a bath with medium-temperature water, with the clothes on. Do not do this to an elderly patient as death may occur since blood flows to the surface of the skin restricting flow to the heart and brain.
  • Place hot water bottles (wrapped in a cotton sock) in the patient's armpits and between their legs
  • Monitor the patient and be prepared to give Cardio-pulmonary resuscitation.
  • Remove wet clothing if and only if a dry change is available.
  • If in a wilderness environment (such as camping) and other treatments are not possible, remove wet clothing from the victim and from one other person. Both individuals should get into the same sleeping bag if possible, or wrap in the same blanket, if the sleeping bag is too small.

If the hypothermia has become severe, notably if the patient is incoherent or unconscious, re-warming must be done by trained professionals. Bystanders should only remove the patient from the cold environment and call emergency services to get advanced medical care as quickly as possible.

Moving a severely hypothermic person can—and most likely will—cause ventricular fibrillation (cardiac arrest). So, if possible, wait for trained emergency workers arrive. If help is over thirty minutes away, move the patient to an area that shelters them from the wind and cover or wrap them in a blanket.

If there's any information that can be turned into encyclopedic content, feel free to do so. bCube(talk,contribs); 00:15, 6 December 2006 (UTC)

Hypothermia vs. pneumonia?[edit]

The article states:

Many people confuse Hypothermia and Pneumonia by name, yet they are two utterly different conditions.

To me, these conditions don't sound anything alike and I've never heard anyone confuse them. "Hypothermia" also sounds like "hypothymia" and "hypothyroid," but the article doesn't mention those. Would anyone object to removal of this sentence? Alki 00:25, 7 December 2006 (UTC)

Thank you, Larissah. Alki 17:53, 17 December 2006 (UTC)


Under "Prevention," it is stated:

"This is possibly because the original research into hypothermia mortality in water was carried out in wartime Germany on unwilling subjects. There is an ongoing debate as to the ethical basis of using the data thus acquired."

Is this really relevant? If so, could we get a reference? If not, I'd say take it out. 21:29, 8 December 2006 (UTC)

What data there is appears to be worthless. See my references below. --AJim (talk) 02:01, 10 January 2009 (UTC)

Single blog page source?[edit]

It provides some information, but not enough specific to hypothermia. It also seems we have a lot of external links, which may be considered too much (WP:EL). Insanephantom (please comment on my Editor Review!) 08:29, 7 January 2007 (UTC)

What is it like?[edit]

Yesterday a close friend of mine died of hypothermia. I know that we can never really know what it would be like, but I wonder if someone could say subjectively what it would be like to die of hypothermia. Would it be unpleasant or peaceful? Like slipping to sleep? -- 12:15, 9 June 2007 (UTC)

Well, I haven't been at the point of death, but eventually the feeling in your body would go away and you'd feel very numb. can't say beyond that. (talk) 23:19, 10 February 2008 (UTC)

When I first moved to Alaska, I had many, including a doctor, tell me death by freezing was like falling asleep. After much experience in temperatures down to forty below and more, I found it usually hurts to start freezing. When properly dressed the only symptom at those temperatures is constant running of the nose as it tries not to freeze. If improperly dressed, out walking I would stop, sit in a ball and cover my painful eyes and face till they were not as painful, then continue. Once inside in the warm, collapsing on the floor unconscious until warm, worked. Sleeping in the extreme cold, I once woke to find my left arm had lost all warmth. It felt like a piece of cold rubber. It did not hurt. Trying to sleep while becoming all-body hypothermic, I could not fall asleep. My voice box would make a death rattle and wake me. I never had turn-black frost bite. My hands did get frost nip on the web and outside edge, where the skin surface would freeze, crack, and bleed. Skin callus would grow very rapidly around such cracks. When well dressed, I could only keep my hands out of my mittens about 5 seconds before pain set in. But, well dressed, my face and eyes could be out in the extreme cold in definitely. My eyes would fog up once inside, from their being cold. Overall, it hurts a lot, as the extremities become too cold. I am sorry for your friend, it is very painful. My Flatley (talk) 15:06, 16 August 2011 (UTC)

I know[edit]

I had hypothermia in Janurary of 2006. I was in stage 3, and I took off my clothes for some reason (Paradoxical Undressing), and then curled up in a ball. I couldn't move and stopped shivering, and then uncontrollably started falling asleep. It did feel like I was slipping away, and was peaceful, for some reason, which i cannot explain, I all of a sudden was awake and I could move my body again. I lived (of course) but got frostbite on my toes and now my body is cold all the time, and even in the summer, it feels like my toes are 'freezing'. —Preceding unsigned comment added by (talk) 06:26, 6 December 2007 (UTC)

Seaside misinformation?[edit]

I've removed the following: "Many seaside safety information sources fail to quote survival times in water, and the consequent importance of diving suits. This is possibly because the original research into hypothermia mortality in water was carried out in wartime Germany on unwilling subjects.[citation needed] There is ongoing debate as to the ethical basis of using the data thus acquired." This story seems strange: I have a hard time even understanding what is meant by the term "seaside safety information source". The passage implies that there are people who would benefit from having information about exact survival times in cold water (as opposed to having practical guidelines along the lines of "if it's below x degrees in the water, wear a wetsuit or drysuit"), but that the information is being kept from them due to an ethical debate. Can anyone clarify?

The Nazi data in question appears to be of no value. See my references below. --AJim (talk) 02:05, 10 January 2009 (UTC)

Paradoxical undressing[edit]

First of, I'm not a doctor. But I believe this phenomenom is related to the way humans feel heat and cold.

From my personal experience I know that "slightly too hot" water can feel like very cold water, and vice versa. Additionally, most reports of this phenomenom I have read indicate that the victim felt very hot and thus discarded its clothing.

So, maybe there's not too big of a difference in feeling heat and cold, and once the consciousness is impaired, differentiation might become impossible. Also, reasoning might be lost, as one should be aware that one is cold .. not hot.

On a related note: I guess everybody is farmilar with the "hot hands" one gets after touching very cold things for prolonged periods, like snowballs. This might contribute, too. —Preceding unsigned comment added by (talk) 16:02, 29 May 2008 (UTC)

Loss of Vasomotor Tone and Surge of Blood to Extremities?[edit]

Could the author please provide a citation for the part about blood pouring to the extremities? If not, could one of the editors please add a "citation needed" sticker?

I ask because conventional wisdom says the body shuts off the extremities somehow, and I think that's pretty much as far as a standard Scout or Red Cross first aid course takes it. You'd think they'd mention the other thing if it's known to happen. You'd think they'd want first aiders to know about that.

I tried a quick Web search for hypothermia +"vasomotor tone" and didn't find anything about this phenomenon.

And that's why I think a citation would be a good idea. Kkken (talk) 11:20, 3 August 2008 (UTC)

Nazi discovery of hypothermia?[edit]

Is it not true that many of discoveries regarding hypothermia came from Nazi Germany's human experimentation? Should that be mentioned? —Preceding unsigned comment added by (talk) 11:49, 10 August 2008 (UTC)

I think that was actually the Japanese, the Japanese conducted experiments on POWs and civilians during the Sino-Japanese war in the 1940s. They would throw cold water on people tied outside in the freezing cold, and they actually figured out the optimal temp of warm water those that caught hypothermia had to be immersed in. - ( (talk) 03:55, 23 October 2008 (UTC))

I have in my hands a copy of a Special Article in the New England Journal of Medicine, May 17, 1990, Vol. 322 No. 20 pp 1435-1440, by Robert L. Berger, M.D., Nazi Science - The Dachau Hypothermia Experiments. He cites Alexander, L The treatment of shock from prolonged exposure to cold, especially in water. Combined Intelligence Objectives Subcommittee. Target no. 24 Report no. 250. Washington D.C: Office of the Publication Board, Department of Commerce, 1946.

  • there were experiments. (but the Nazis did not "discover" hypothermia)
  • the original data from these experiments has been lost
  • the 228-page report by Leo Alexander contains a reproduction of a 56-page report to Heinrich Himmler by the Dachau investigators
  • Dr. Berger says that this report "is essentially the only primary reference cited in the literature on the Dachau study."
  • Dr. Berger concludes "On analysis, the Dachau hypothermia study has all the the ingredients of a scientific fraud, and rejection of the data on purely scientific grounds is inevitable. They cannot advance science or save human lives." ... "Future citations are inappropriate on scientific grounds."

Sexual Activity[edit]

I know now that alcohol makes hypothermia worse in spite of making people FEEL warm (hence it being recommended in the past)...but what about sex? Sexual activity make people feel warmer, but does it actually make them warmer. Does sexual activity, or rigorous exercise for that matter, generate heat from the fat people have in their bodies + the motions they make, or those it simply cause heat to rise to the surface and therefore drop core temp faster? ( (talk) 03:58, 23 October 2008 (UTC))

Oh god. Do you have sex with your winter clothes on, while you are freezing at the bus stop? -- (talk) 15:08, 5 January 2011 (UTC)

What does this mean?[edit]

The fingers decrease dexterity due to pain or numbness, safety, work capacity, and increase the risk of developing nonfreezing cold injury.[1][3]

This sentence seems to be half-finished. —Preceding unsigned comment added by (talk) 23:51, 14 November 2008 (UTC)

What air temperatures increase the risk for the different stages of hypothermia?[edit]

There is information in this article about water temperatures and body temperatures but there isn't anything on what air temperatures or temperature at ground level that would cause the different stages of hypothermia. This would be very interesting to know. --John10001 (talk) 14:30, 23 November 2008 (UTC)

Having experienced hypothermia several times I've looked for that information as well. The variables are so many: air temperature, dewpoint, wind speed, shelter (or not), clothing (adequate layering ?- cotton or non cotton ?), how recently a good meal had been eaten; that it is difficult to make a hard and fast rule. It has been written ( and I'll hunt for the reference some day ) that more people get hypothermia when the temperatures are in the 35-50 F temperature range than in the 0 - 15 F range....presumeably because in the colder temps you are on guard for that sort of thing. In the 35 years I've been hiking, I'm always on my guard if the temps are under 50 F. Robert Falcon (talk) 21:40, 4 March 2009 (UTC)

Could someone redo the citation?[edit]

In the section under Paradoxical Undressing, there is a citation in parentheses. This should be changed, if I'm not mistaken. —Preceding unsigned comment added by (talk) 00:35, 11 December 2008 (UTC)

US Coast Guard and 50/50/50 rule[edit]

There's a paragraph claiming that the US coast guard advocates lifejackets for preventing hypothermia on the grounds that if you're in water at 50 degrees F for 50 minutes, you're 50% more likely to live if you wear a lifejacket. Unfortunately, the citation link is broken and it looks like that page really no longer exists; and the modest amount of searching I've done hasn't tracked down anywhere where the USCG still promotes anything that looks like that 50/50/50 rule. Can anyone do better? If not, we should either (1) delete the paragraph, (2) say that the USCG *used to* talk about a 50/50/50 rule, or (3) find some other entity that still does and cite them instead. Also, it's totally unclear to me that this is really about hypothermia *prevention*; surely at least part of the point is that if you're hypothermic and your muscles aren't working right then you won't be able to swim any more, so if you have no flotation device then you die. I've made that paragraph say "protection" rather than "prevention" for this reason, but I'm open to correction from people who know more about this than I do.

The Article states (under Hypothermia#Water), that Heliox has to be pre-heated, due to it´s "higher thermal mass". I don´t know about pre-heating, but the heat capacity of Helium is 30% lower than Oxygen´s per mole (or volume), and 80% lower per mass. Helium has a high heat conductivity, but that should be irrelevant, as any Air/Oxygen/Helium is definitely at body temperature when breathed out. -- (talk) 15:21, 5 January 2011 (UTC)

Unnecessary POV paintings[edit]

The paintings that I removed are unnecessarily POV, painted in a clearly Romantic style to represent Russian nationalism, and lo, painted by a Russian during the Romantic era. I left Hannibal as a compromise, because for some reason people wanted this stuff despite it being absurd for a primarily scientific article, and it lacks a blatant message except for the power of nature, which I suppose kind of fits. Despite that, a blizzard technically has nothing to do with illustrating hypothermia, so I'm not pleased with leaving it in. There is no need for paintings of any kind in this article.

Does it? I don't see signs of hypothermia. I see cold weather, I see people walking and hunched, and I see maybe some dead soldiers, but I don't see clearly hypothermia. If Wikipedia wants to be taken seriously, maybe it should use actual clinical images instead of contextual POV paintings. Seriously, it's ridiculous. This is scientific? This has no place in a serious article concerning health. It's also stunningly incomplete and thus misleading and erroneous: leaving Russia has a lot to do with scorched earth and no food, not just basic hypothermia. It's just so unprofessional. Diagnose hypothermia from that painting. I defy the possibility. It doesn't even pass the laugh test. There's a few dead people and it's cold, ah so it MUST be hypothermia. That is completely illogical, incomplete, and makes a lot of assumptions. Beyond that, it's bizarrely POV to have in a scientific article. As I said, it's in Romantic style, clearly German and Russian nationalist works, and they're here for no reason. Wikipedia is designed as a serious encycopledia, or is supposed to be, and I could go add paintings that have tangential relevance to every article here and they'd be removed as non-sequiter vandalism in any article worth its salt. So either spend a lot more than four words justifying this absurdity, or just remove them. The Ankou (talk) 21:22, 8 February 2011 (UTC)
This seems to be a very emotional issue for you, which makes it a bit harder to deal with than it needs to be. Looie496 (talk) 21:41, 8 February 2011 (UTC)
Donate money to this site and watch it fail. Now I have a proprietary relationship to this, so let's try to prevent it from being dreck, eh? Also, I don't like being dismissed offhand. Anyway it should be easy. So far, I'm the only one who has argued his point with any logic. I have been neither disrespectful nor unreasoned, and yet I find myself being insulted through a pernicious brevity. Even so, I'm being civil. I have said the article as is is ridiculous, but keep in mind I have not insulted anyone personally. That would be overly emotional. I would not try to fix the site if I didn't care on some level, and obviously that entails some degree of emotional involvement. The Ankou (talk) 00:41, 9 February 2011 (UTC)

Hypothermia top range[edit]

In the hospital environment we classify patients under 36.0 C as hypothermic as opposed to under 35.0 C. This is according to published UK NICE Guidelines. (April 2008) — Preceding unsigned comment added by (talk) 10:50, 28 June 2011 (UTC)

Merger proposal[edit]

I propose that Terminal burrowing be merged into Hypothermia … the phenomenon isn't seen in the context of any other medical conditions. The small amount of content in Terminal burrowing, which is a stub, can easily be explained within this article without producing an article that is too long. Most of the content in that article has been replicated within the header on that subject in this article. In addition, other, perhaps more significant symptoms such as paradoxical undressing don't have their own articles. Jswinarton (talk) 09:24, 30 November 2011 (UTC)

Agree. --Doc James (talk · contribs · email) 22:13, 30 November 2011 (UTC)



As the temperature decreases further physiological systems falter and heart rate, respiratory rate, and blood pressure all decreases. This results in an expected HR in the 30s with a temperature of 28 °C (82 °F).[3]

HR - I assume means heart rate? It's not defined anywhere else in the article.

New Warming Collapse (Afterdrop)[edit]

I'd like to see more mention in the article of afterdrop, since this seems to be a controversial topic. Three references are cited supporting the idea that rewarming collapse is potentially not a real thing, yet rescue workers are still taught not to provide too much external heat too quickly. (I know one personally, which is how I became aware of this issue.) Therefore, references should be provided to support the idea that no one suffering from severe hypothermia should ever, for instance, be placed in a hot bath. Here is one such reference: (Skip to Afterdrop section.) While it is not a paper, this content is taught to rescue workers and the general public, and caused me, personally, some confusion. Additionally, while Wikipedia is not intended to be a medical reference, people do use it as such, or at least, people may have this knowledge in the back of their head later on when there's an emergency. If rewarming *can* lead to death, it would be irresponsible to not at least mention the controversy, with references. Anything less would be NPOV.

Additionally, the term "afterdrop" should be mentioned, since this seems to be commonly used. lunaverse (talk) 20:37, 15 February 2012 (UTC)

Sure if you can find a proper review article per WP:MEDRS that we can comment on it. I have not seen reliable literature that comments on afterdrop but am unable to look at this time due to the poor interenet where I am.--Doc James (talk · contribs · email) 13:02, 24 February 2012 (UTC)

NOTE: Hypothermia victims may experience "Warming Collapse (Afterdrop)" even without exposure to rapid warming. Stationary victims may experience rapid changes (drop) in core temperature simply by standing or exerting effort using extremities (as much as a 10F drop has been observed). Effort should be made to limit any exertion by victims until after rewarming. Rewarming is not complete when the victim stops shivering. The effects of extreme exposures can last for a day or more. — Preceding unsigned comment added by (talk) 03:59, 28 December 2012 (UTC)

Why on earth would a hypothermia article be semi-protected?[edit]

Anonymous, who is legion and the author of most of the content in WP, is not able to contribute.

Locking should be done only for very good reasons, which are hard to imagine for an article on hypothermia.

If allowed, I would have folded each of these ranges into the appropriate sub-section:

Mild 32–35 °C (90–95 °F); moderate, 28–32 °C (82–90 °F); severe, 20–28 °C (68–82 °F); and profound at less than 20 °C (68 °F).

Oh, well. — Preceding unsigned comment added by (talk) 18:09, 19 April 2012 (UTC)

Irrelevant sentence in opening[edit]

At the end of the opening paragraph, this appears: "One of the lowest documented body temperature from which anyone has recovered was 13.0 °C (55.4 °F), in a near-drowning incident involving a 7-year-old girl in Sweden in December 2010.[1]" This is of questionable relevance to the article, and certainly doesn't belong in the opening. (talk) 17:04, 23 May 2012 (UTC)

This is highly relevant, as the general POV of the article is biased towards scare tactics with non-scientific sources published by rescue authorities and boating societies. I swim for an hour three times a week during the winter without a wetsuit in water that is only 9 °C.Dikteren (talk) 02:21, 29 March 2013 (UTC)

Sub Classification[edit]

Hypothermia should be subdivided into two distinct classifications, immersion and exposure (or exhaustion). Immersion is indicative of an individual being rapidly cooled such as when falling through ice. Exposure hypothermia is the gradual drop in core body temperature over an extended period of time. Exposure hypothermia presents unique characteristics which can complicate the treatment. Exposure hypothermia should not be evaluated based on the core temperature alone. Long term exposure over several hours may initially show increases in core body temperature as the body elevates the metabolic rate in response to the threat (as much as 1F has been observed). Skin temperature at the extremities may drop significantly with the expected complications including numbness, or in severe cases frostbite, joint and bone damage. Treatment of exposure hypothermia showed the greatest success when subjects were immersed in warm water (85F) and gradually increasing the water temperature (105F). Only the torso should be immersed to limit the risk of rewarming shock. Hot air treatments proved ineffective in field conditions. For references examine the studies performed at the Navy Experimental Diving Unit (NEDU) 1988-1990 by the Thermal Underwater Research Diving Subjects (TURDS) - No this is not a joke but is a reference to the tank which used sewer pumps to simulate current.

Medically qualified people please check this article.[edit]

I tried to use good sources but I'm unsure about some material.

  1. Several sources suggest giving chocolate drinks to hypothermia patients.
  2. Several sources suggest avoiding caffeine.
  3. Chocolate contains caffeine.
  4. Is the caffeine in chocolate too little to matter?
  5. Is there disagreement among experts?

Also some sources recommend hot water bottles but others warn this could burn the skin. I'm not sure what to write. Proxima Centauri (talk) 07:03, 19 January 2014 (UTC)

How far should hypothermia victimw be moved? Proxima Centauri (talk) 11:59, 19 January 2014 (UTC)

Let try not to say the same thing multiple times[edit]

For example this edit added [3] "Handling hypothermia patients gently is important" while the article already said "Moving the person as little and as gently as possible is recommended as aggressive handling may increase risks of a dysrhythmia" It added "The patient should be moved indoors or to a warm place." the article already said "providing properly insulated dry clothing and moving to a warm environment" It added "Gently hugging the patient transfers heat from the helper to the patient." the article already said "Person to person warming is also helpful." I am confused? Doc James (talk · contribs · email) (if I write on your page reply on mine) 12:37, 22 January 2014 (UTC)

I think we need to explain what medically unqulified prople giving first aid should do and what should be left to experts. That's why I wrote the first aid section. Proxima Centauri (talk) 15:00, 22 January 2014 (UTC)
The content is already in other sections. We do not break up treatment by who can do it for any other article. We do not use the term patient. Did you read WP:MEDMOS?

@Jmh649: please be so good as to explain why you reverted my edit i.e why you consider the confusion and contradiction should be preserved rather than edited, in a minor manner, to remove both?

I would have understood a revert that had then been an improvement on what I did, or even one that changed it entirely to deal with the problem, but neither have been done. Consequently it is hard to find the reversion anything other than wilful.

For any who stumble upon this and are therefore unable to figure out what on Earth it's all about, the current article states the normal temperature in the introduction and then immediately contradicts itself. I corrected that with a minor edit using the information provided in the article. Jmh649 merely reverted the change, before wading in to edit the page to suit his/her own preference.

Consequently I have returned the favour.

BTW, would it have been so hard to simply comment: "Removed duplicated references" rather than: "yes we can ref ever sentence" to explain your subsequent "work"???! (grammatical mistake in original)

LookingGlass (talk) 14:10, 10 June 2014 (UTC)

  1. You added a ref tag to "Hypothermia is then defined as any body temperature below 35.0 °C (95.0 °F)" I added a reference
  2. Hypothermia usually occurs from exposure to low temperatures, and is frequently complicated by alcohol to "may be". Ethanol is one of the most common complicating factors if not the most common.
  3. Stating what the normal human body temperature is deemed to be is a better layout.
  4. What is with the period before and after the ref ".[4]." Doc James (talk · contribs · email) (if I write on your page reply on mine) 22:26, 10 June 2014 (UTC)
By the way which "confusion and contradiction" are you referring to? Doc James (talk · contribs · email) (if I write on your page reply on mine) 22:29, 10 June 2014 (UTC)

Your comment (response/answer?!?) makes no sense. Perhaps your level of activity here led to your confusion and you are addressing some other matter? The issue concerned an almost trivial and elementary clarification of the existing text. Consult the edit and you will find your questions addressed there. I added nothing nor varied anything in the article beyond that. As your apparently unnecessary and unhelpful reversion, contrary to your summary of it, did NOT refer to any detailed explanation, I commented. On a general note, it seems from other edits that you prefer the old-fashioned style of academic prose, one that leans heavily on a priori knowledge and assumption. Personally I find that unhelpful as it leads to a tangled and clumsy form of expression which in turn generates confusion. LookingGlass (talk) 10:58, 20 December 2015 (UTC)

This is not true "Whilst normal human body temperature in adults ranges from 33.2–38.2 °C (91.8–100.8 °F)"
These are not the typically accepted range of normal human body temperatures Doc James (talk · contribs · email) 16:54, 20 December 2015 (UTC)

Fix the the history citations, they are rather poorly done:

Section in question


The armies of Napoleon retreat from Russia in 1812.

Hypothermia has played a major role in the success or failure of many military campaigns from Hannibal's loss of nearly half his men in the Second Punic War (218 B.C.) to the near destruction of Napoleon's armies in Russia in 1812. Men wandered around confused through hypothermia, some lost consciousness and died, others shivered, later developed torpor and tended to sleep. Others too weak to walk fell on their knees, some stayed that way some time resisting death. The pulse was of some was weak and hard to detect, others groaned, yet others had eyes open and wild with quiet delirium.[5] Loss of life to hypothermia in Russian regions continued through the first and second world wars, especially in the Battle of Stalingrad.[6]

refers to quotations in Rosen's Emergency Medicine, instead of poor paraphrasing, just apply quotes from the source material which Rosen's did from Moricheau-Beaupré PJ, A treatise on the effects and properties of cold, with a sketch, historical and medical, of the Russian Campaign. [John Clendining, Trans.]. Edinburgh: Maclachnan and Stewart; 1826, 123–5.

“some, pale and depressed by inanition swooned away and died, stretched on the snow. Others … were seized by shivering to which quickly succeeded languor and propensity to sleep. They were seen walking insensible and ignorant where they went: scarcely could you succeed in making them understand a few words … In a word, when no longer able to continue walking, having neither power nor will, they fell on their knees. The muscles of the trunk were the last to lose the power of contraction. Many of those unfortunates remained some time in that posture contending against death. Once fallen, it was impossible for them with their utmost efforts to rise again … Their pulse was small and imperceptible; respiration, infrequent and scarcely perceptible in some, was attended in others by complaints and groans. Sometimes the eye was open, fixed, dull, wild, and the brain was seized by quiet delirium…”

I don't see why this page should be protected, by not being open to edits it has suffered. I can see protecting living people that are highly controversial. What's the point of wikipedia otherwise??

Hypothermia and fever cannot both be defined as the same range[edit]

Hyperthermia and fever, are defined as a temperature of greater than 37.5–38.3 °C (99.5–100.9 °F).

This is the last line of the classification setting. Perhaps since hypothermia ranges and normal ranges have been defined this should just say fever?

Why can hypothermia and fever not be defined as the same temperature? They differ by cause rather than temperature. Doc James (talk · contribs · email) 11:49, 25 November 2014 (UTC)
