Anna Elisabeth Johansson Bågenholm [2] (born 1970) is a Swedish radiologist from Vänersborg, who survived after a skiing accident in 1999 left her trapped under a layer of ice for 80 minutes in freezing water.
Survival with good function also occasionally occurs even after the need for hours of CPR. [2] Children who have near-drowning accidents in water near 0 °C (32 °F) can occasionally be revived, even over an hour after losing consciousness. [74] [75] The cold water lowers the metabolism, allowing the brain to withstand a much longer period of ...
The amount of time a person can survive without a source of water (including food which contains water) depends on the individual and the temperature. As temperature increases, so does water loss, decreasing the amount of time a person can survive without water. The longest anyone has ever survived without water was 18 days. [8]
[citation needed] When combined with this high humidity, the theoretical limit to human survival in the shade, even with unlimited water, is 35 °C (95 °F) – theoretically equivalent to a heat index of 70 °C (158 °F). [22] [23] Dry heat, on the other hand, can cause dehydration, as sweat will tend to evaporate extremely quickly ...
Hypothermia is a condition where bodily temperature drops too low to perform normal voluntary or involuntary functions. Cold water causes "immersion hypothermia", which can cause damage to extremities or the body's core, including unconsciousness or death. [2] The HELP reduces exposure of high heat loss areas of the body.

The first stage of cold water immersion syndrome, the cold shock response, includes a group of reflexes lasting under 5 min in laboratory volunteers and initiated by thermoreceptors sensing rapid skin cooling. Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling ...
