Hyperthermia, in its
advanced state is referred to as heat stroke or sunstroke It's an acute
condition which occurs when the body produces or absorbs more heat than
it can get rid of. Usually caused by prolonged exposure to high
temperatures and humidity, the heat-regulating mechanisms of the body eventually
become overwhelmed and unable to effectively deal with the heat. This causes
the body temperature to climb uncontrollably. Hyperthermia is a medical
emergency which requires immediate treatment.
Normally the body rids
itself of excess heat by radiating heat to the surrounding air and
increasing this heat transfer by sweating which provides a very
effective means of evaporative cooling. If you are accustomed to going
from an air conditioned house to an air conditioned car to an air
conditioned workplace, you may find it very difficult to shift to a
survival mode that requires living in even moderately high temperatures.
It can take up to 2 weeks for your body to acclimate to a high
temperature environment.
Adverse High Heat Conditions
The worst conditions are those that involve high heat and high
humidity. High humidity significantly reduces the evaporation of
sweat from the body. Profuse sweating drags a large amount of water and
salt from the body that must be replaced to stay alive.
Prevent high heat
buildup in your shelter
After an event that causes loss of electrical power you may find
that keeping your shelter cool will be difficult. A typical house
has areas that stay cooler in the summer than others. North facing
rooms that are not subject to direct sun are better than southern
exposed parts of the house. Fully enclosed basements can stay cool
all summer long. A house that is closed up can have temperatures
that exceed the outside temperature.
Other strategies involve
removing excess heat buildup in your home during the day and trapping
cooler night air inside.
Know the signs and
symptoms of heat related illness and have a plan to provide treatment.
