  • 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 ● ● ● ● ● ● ● ● Dehydration Confusion Dizziness Fainting Fatigue Headache Nasea Rapid heartbeat
  • 16. Treatment for Hyperthermia ● ● ● ● Drink cold fluids Sit in shade Bathe in an ice-bath Turn on fans
