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.

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?

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?

“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

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?

Three Levels of Heat Illnesses Heat Cramps Heat Exhaustion Heat Stroke

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

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

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

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

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

CAUTION!

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

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

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

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

Heat Index Chart Compares Temperature to Humidity level to give a more accurate temperature feel (Example: 86 degrees but feels like 98) Example on page 24 Weather channel or websites

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

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

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

Lightning

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

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

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