Mission + Korey Stringer Institute

Working together to raise awareness for Heat Safety

Exercise in the heat impacts performance and can lead to heat-related illness. Heat related illness is one of the leading causes of death and disability among athletes. It is also treatable and preventable.

Mission is partnering with the Korey Stringer Institute, the leading authority in heat illness and the prevention of sudden death in sports, to build the MISSION ThermoChamber to test and validate every product before it ever hits the field. The goal is to provide first-rate information, resources, assistance and advocacy for the promotion of preventing heat-related illness.

Stay safe and active.

Strategies to stay cool in intense heat

Stay Hydrated

Drink enough fluid to prevent dehydration. An average 175 lb. male loses approximately 34 fl. oz. of fluid per hour of exercise. For each 34 fl. oz. lost, it is recommended to drink 40 oz. of water.

Keep Cool

If you feel overheated, decrease your intensity or stop. Also take steps to cool yourself including: lying in a cool, shady place or applying cooling towels to the body.


It takes time for the body to adapt to the heat. Ease into an exercise regimen in the heat, especially in the first week.


These can include nausea, headache, weakness, fainting, poor concentration, light-headedness, loss of muscle coordination, fatigue and vomiting.

Be Smart

Dress appropriately with clothing or accessories that are light, breathable and cooling. Try to avoid exercise in the warmest times of the day, and have a plan to contact medical professionals in an emergency.

Watch the Weather

When the environment stress is high, modify your exercise by taking more breaks and using cooling methods, like a cooling towel.
