What are the health effects of EXPOSURE to COLD

Cooling of body parts may result in various cold injuries (A) nonfreezing injuries, (B) freezing injuries  and (C) HYPOTHERMIA  which is the most serious. Nonfreezing cold injuries include chilblain, immersion foot and trenchfoot. Frostnip and frostbite are freezing injuries.

Toes, fingers, ears and nose are at greatest risk because these areas do not have major muscles to produce heat. In addition, the body will preserve heat by favouring the internal organs and thus reducing the flow of blood to the extremities under cold conditions. Hands and feet tend to get cold more quickly than the torso because:
  • they lose heat more rapidly since they have a higher surface area-to-volume ratio, and
  • they are more likely to be in contact with colder surfaces than other parts of the body.
If the eyes are not protected with goggles in high wind chill conditions, the corneas of the eyes may freeze.

The most severe cold injury is hypothermia which occurs from excessive loss of body heat and the consequent lowering of the inner core temperature (internal temperature of the body). Hypothermia can be fatal.
