Human body temperature
Temperature variation
44 °C (111.2 °F) or more – Almost certainly death will occur; however, people have been known to survive up to 46.5 °C (115.7 °F). 43 °C (109.4 °F) – Normally death, or there may be serious brain damage, continuous convulsions and shock. Cardio-respiratory collapse will likely occur. 42 °C (107.6 °F) – Subject may turn pale or remain flushed and red. They may become comatose, be in severe delirium, vomiting, and convulsions can occur. Blood pressure may be high or low and heart rate will be very fast. 41 °C (105.8 °F) – (Medical emergency) – Fainting, vomiting, severe headache, dizziness, confusion, hallucinations, delirium and drowsiness can occur. There may also be palpitations and breathlessness. 40 °C (104 °F) – Fainting, dehydration, weakness, vomiting, headache, breathlessness and dizziness may occur as well as profuse sweating. Starts to be life-threatening. 39 °C (102.2 °F) – Severe sweating, flushed and red. Fast heart rate and breathlessness. There may be exhaustion accompanying this. Children and people with epilepsy may be very likely to get convulsions at this point. 38 °C (100.4 °F) – (Classed as hyperthermia if not caused by a fever) – Feeling hot, sweating, feeling thirsty, feeling very uncomfortable, slightly hungry. If this is caused by fever, there may also be chills. 36.5–37.5 °C (97.7–99.5 °F) is a typically reported range for normal body temperature. 36 °C (96.8 °F) – Feeling cold, mild to moderate shivering. Body temperature may drop this low during sleep. May be a normal body temperature. 35 °C (95 °F) – (Hypothermia is less than 35 °C (95 °F)) – Intense shivering, numbness and bluish/grayness of the skin. There is the possibility of heart irritability. 34 °C (93.2 °F) – Severe shivering, loss of movement of fingers, blueness, and confusion. Some behavioral changes may take place. 33 °C (91.4 °F) – Moderate to severe confusion, sleepiness, depressed reflexes, progressive loss of shivering, slow heartbeat, shallow breathing. Shivering may stop. Subject may be unresponsive to certain stimuli. 32 °C (89.6 °F) – (Medical emergency) – Hallucinations, delirium, complete confusion, extreme sleepiness that is progressively becoming comatose. Shivering is absent (subject may even think they are hot). Reflex may be absent or very slight. 31 °C (87.8 °F) – Comatose, very rarely conscious. No or slight reflexes. Very shallow breathing and slow heart rate. Possibility of serious heart rhythm problems. 28 °C (82.4 °F) – Severe heart rhythm disturbances are likely and breathing may stop at any time. The person may appear to be dead. 24–26 °C (75.2–78.8 °F) or less – Death usually occurs due to irregular heart beat or respiratory arrest; however, some patients have been known to survive with body temperatures as low as 13.7 °C (56.7 °F). There are non-verbal corporal cues which can hint at an individual experiencing a low body temperature, which can be used for those with dysphasia or for infants. Examples of non-verbal cues of coldness include stillness and being lethargic with regards to kinesiological movement, sneezing, unusual paleness of skin among Caucasians, and, among males, shrinkage, and contraction of the scrotum.
