1. Exercise, Weather and Hydration--Hyperthermia
Common Core Standard
NPA 4.2
Use appropriate methods for avoiding and responding to climate-related physical
conditions during physical activity.
You have arrived at Exercise, Weather and Hydration--Hyperthermia. We will be covering the Common Core Standard called NPA 4.2 What we want is for you to be able to do is use appropriate methods for avoiding and responding to climate-related physical conditions during physical activity.

2. Think about it… People exercise in all kinds of weather.
What kind of things should I be concerned about when exercising in extreme temperatures?
What role does hydration play in all of this?
These are the topics we will be discussing in this lesson.
Have you ever heard stories of people who were physically fit who exercised in extreme heat and died? It happens almost every year with many football players and other athletes who exercise in extremely hot conditions. What can you do to avoid becoming a victim of extreme heat? Let’s find out!

3. Hyperthermia
Pay attention to the word HYPER in the condition called hyperthermia. It sounds very similar to another condition that is the exact opposite, so we don’t want you to get confused about which term you are learning about. This is a condition caused by extreme heat. It sounds very much like hypothermia, which is caused by extreme cold temperatures. For this lesson, we will just focus on the HYPERTHERMIA.

4. Hyperthermia has 3 Stages
Heat Cramps
Heat Exhaustion
Heat Stroke
Living in North Carolina gives us a good balance of weather, but we do often have temperatures in the summer months that go over 100 degrees. When you are out exercising or are active in extremely hot conditions, be aware of the things that may happen to you. Hyperthermia does have 3 stages and many of us have experienced some of them. What do these stages look like? You will find out in the next three slides.

5. Hyperthermia – STAGE 1
Heat cramps are painful muscle contractions, mainly affecting the calves, quadriceps and abdominals. Affected muscles may feel firm to the touch. Your body temperature may be normal.
Stage 1 - Heat Cramps – Muscles will contract and cramp. They will feel very firm.

6. Hyperthermia – STAGE 2
With heat exhaustion, your body temperature rises as high as 104 F (40 C) and you may experience nausea, vomiting, headache, fainting, weakness and cold, clammy skin. If left untreated, this can lead to our third and final stage.
Stage 2 – Heat Exhaustion-A core body temperature of up to 104 degrees. Can cause vomiting, headache, fainting and clammy skin.

7. Hyperthermia – STAGE 3
Stage 3 – Heat Stroke-A core body temperature of greater than 104 degrees. The body will stop sweating and be hot to the touch. Can lead to brain damage, organ failure or even death!
Heatstroke is a life-threatening emergency condition that occurs when your body temperature is greater than 104 F (40 C). Your skin may be hot, but your body may stop sweating to help cool itself. You may develop confusion and irritability. You need immediate medical attention to prevent brain damage, organ failure or even death.

8. Hyperthermia-Treatment
Get Help! If you suspect a heat stroke call 911.
Get the person out of the hot environment
Water. Drink it! Get hydrated! It can lower your body temperature, prevent headaches and increase alertness. (Avoid alcohol! It can make the problem worse.)
Ice packs and a very cold bath to get the core body temperature back to 98.6
You are not always around a phone to get help. If you trying to help someone who you suspect is suffering heat exhaustion or heat stroke, get them out of direct sunlight and into some kind of shade. Get them water! Remove any excess clothing and find help when you can. The important thing to remember is to get that core body core temperature back to 98.6.

9. Hyperthermia - Prevention
Avoid exercise in the middle of the day
Easy workouts! Avoid strenuous activity.
Wear lightweight clothes that are white. Dark colors absorb light and attract heat. Try wearing a wide hat that blocks the sun.
Use sunscreen! A sunburn reduces your body’s ability to cool itself.
Drink plenty of water!
If you're unfit or new to exercise, be extra cautious when working out in the heat. Your body may have a lower tolerance to the heat. Reduce your exercise intensity and take frequent breaks. Pay attention to weather forecasts and heat alerts. Know what the temperature is expected to be for the duration of your planned outdoor activity.

Just remember that the word HYPER means HOT! We will next explore the total opposite condition called hypothermia.
