4. Thermoregulation
Thermoregulation is the ability for an organism keep its
body heat with in certain boundaries and keep that body
heat at 98.6˚ Fahrenheit.

5. The Hypothalamus
The hypothalamus controls your body
temperature. It is a portion of the lower-middle
brain that also controls hunger, thirst, and
sleep.

6. How Does The Hypothalamus Work?
● If your body gets too cold, the hypothalamus activates
warming mechanisms.
● If your body gets too warm, the hypothalamus activates
cooling mechanisms.
● The warming and cooling work through feedback loops
to maintain homeostasis.

7. What Is Homeostasis?
Homeostasis is how humans and many other
organisms maintain a stable internal
environment. This includes maintaining pH,
water balance, and body temperature. Normal
body temperature is 98.6˚ Fahrenheit or 37˚
Celsius.

8. How We Warm and Cool Our Body

9. What Is Hypothermia?
Hypothermia is when your body cools down so much that
warming mechanisms won’t bring your body temperature
back up to homeostasis.
You can get hypothermia from being in very cold weather
or water for an extended period of time.

10. Avoiding Hypothermia
● Dress warmly in layers
● Base layer anything but cotton
● Outer layer should be waterproof and windproof like a
wind breaker
● Wear hat or beanie, gloves, scarf, and warm pants to
protect large blood vessels
● When you get too hot, remove the outer layer to prevent
sweating
● Carry at least one thermal blanket in your survival kit

11. Symptoms of Hypothermia
●

●
●
Shivering (If constant, that means the body can not warm itself)
Loss of coordination
Mumbling and slurring of speech
Difficulty forming thoughts
Confusion
Lack of energy
Unawareness of life threatening situation
Person is unconscious
Pulse Is weak
Shallow breathing

12. Treatment for Hypothermia
● Quickly find shelter and cover yourself with a blanket
near a heat source
● Remove wet clothes immediately
● Skin to skin contact under blanket
● Give warm drinks, but nothing containing alcohol or
caffeine
● Place warming packs on chest and groin area but not
on legs or arms

13. What Is Hyperthermia?
Hyperthermia is when you get too hot and you
can get heatstroke, heat exhaustion, or heat
cramps. Your body temperature is usually
hyperthermic if it’s above 98.8˚ Fahrenheit.

14. Avoiding Hyperthermia
● Drink plenty of cold fluids
● Wear one t-shirt made with thin fabric and
wear shorts too
● Wear a hat that can shade you from the
sun’s rays

15. Symptoms of Hyperthermia
