List the factors related to hypothermia.

Step 1 of 2

Hypothermia is a condition in which the core body temperature is below 35^o C. The condition occurs when the rate of heat loss from the body exceeds the rate of heat production. The factors that contribute to hypothermia are as follows:

• Gradient for heat loss: When the external temperature is less than skin temperature, body loses heat through convection. To counter the heat loss, physiological adaptations like constriction of peripheral vessels and shivering occurs

• Vapour pressure of cold air: Cold air has low vapour pressure and thus encourages the evaporation of moisture from skin

The combined effect of both the above said factors can lead to deadly consequences.
