1. Mind Streaming Choose a partner
Stand up and for 60 seconds one partner will tell the other everything they know about;
exercising in the heat,
heat related illness, and
any known precautions to exercising in the heat.

2. HOT weather RISKS
In order for your body to remain healthy your core body temperature must remain within very narrow limits as to not get too hot or too cold.
Thermo-regulation = regulation of body temperature
What are some different examples of things that may change your body temperature?

3. HOT weather RISKS
Think back to some changes our body experiences when we exercise- how do we feel temperature wise after we exercise?
When we exercise, our core body temperature increases (even more so when we exercise in the heat)
Why?

4. “Human Air Conditioning”
Our body cools itself off during exercise:
Perspiration (“Sweating”)= heat being transferred out of the body through body fluid being evaporated
Blood redistributes itself to surface of body
Causes skin to appear red and flushed

5. Dehydration Dehydration = loss of body fluids
Loss of body fluid is greater than the amount of fluids taken in during exercise.
Drinking lots of fluids during exercise is best way to prevent Dehydration.
What types of drinks are good to drink during exercise?

6. Three Levels of Heat Illnesses
Heat Cramps
Heat Exhaustion
Heat Stroke

7. Painful involuntary muscle spasms in the arms, legs and mid section.
Heat Cramps
Painful involuntary muscle spasms in the arms, legs and mid section.
Caused by imbalance of sodium and potassium in muscles
Bananas?
Treatment:
stop activity
Drink plenty of water, fluids, electrolyte replacement
Maintain a balanced diet

8. Signs of Heat Exhaustion
Increased sweating
high body temperature
cool wet skin
light headed
lack of coordination skills

9. Heat Exhaustion Caused by excessive fluid loss Treatment:
Stop ALL activity
Remove yourself from sun and/or heat
Drink lots of water, fluids
Seek medical treatment if condition does not improve

10. Extremely Dangerous, possibly fatal
Heat Stroke
Extremely Dangerous, possibly fatal
Inability to Sweat
Hot and dry skin
Fast breathing
Seizures, Unconsciousness

11. Heat Stroke
Caused by sweating and excessive loss of fluids during exercise or exposure to heat
Treatment:
SEEK IMMEDIATE MEDICAL TREATMENT
Remove from source of heat
Stop all activity and drink lots of fluids

12. Six forms of sun protection
Drink fluids
Clothing
Sun screen
Shade
Hat
Sunglasses

13. CAUTION!

14. Extreme Environment Conditions
Environmental conditions play a key role in the following:
choosing the intensity level for your workout
Exercise safety
Equipment necessities

15. Hot, Humid Weather
Exercising in extreme heat or humid conditions can be very dangerous:
Humidity = amount of water vapor in the air
Exercising in extreme humidity can cause hyperthermia
Hyperthermia = overheating, when your body temperature rises to high

16. Hot, Humid Weather
Guidelines to cope with exercising in heat-related conditions:
Begin gradually
Drink water
Wear proper clothing
Light, porous clothing
Light colors

17. Hot, Humid Weather
Guidelines to cope with exercising in heat-related conditions:
Rest frequently
Avoid extreme heat and humidity
Use heat index
Get out of heat and cool when heat related illness begin to occur

18. Cold, Windy, Wet Weather
Exercising in cold, windy, and wet weather also requires precautions
Hypothermia = excessively low body temperature
Shivering
Numbness
Drowsiness
Muscular weakness
Confusion and disorientation

19. Cold, Windy, Wet Weather Frostbite = when body parts become frozen
Skin becomes white or grayish
Pain early followed by numbness
Blisters

20. Cold, Windy, Wet Conditions
Avoid Extreme Cold
Wind chill factor
Dress Properly
Several layers of lightweight clothing
Avoid exercising in icy or cold conditions
Foot injuries and falling

21. Lightning

22. Lightning dangers Can be extremely dangerous/ deadly
Very common in Central Florida
Avoid all and any exercise or sport related activities when storm is approaching:
Open field activities
Open water activities

23. How far away is lightning?
When you see a clear lightning strike you can count to get an approximate distance based on the following thunder.
For every (approximate) 5 seconds you count between seeing strike until thunder sounds = about 1 mile
Example: 15 seconds = about 3 miles away
Avoid any outside activities when lightning is within 10 miles

24. Summary
Describe three ways how weather conditions can affect participation in physical activities?
