Staying Safe in the Heat and Knowing the Warning Signs

The summer sizzle is on! Temperatures are once again on the rise with another heat wave upon us.

Exposure to too much heat without relief or adequate fluid intake can cause various types of heat-related illness. It’s especially important that children and teenagers stay hydrated because they produce more heat with activity, than adults, and sweat less (sweating is one of the body's cooling mechanisms).

Children and teens with chronic health problems, or who take certain medications, may be more susceptible to heat-related illnesses. Also, those who are overweight or wear heavy clothing during exertion, such as marching band or football uniforms, are more susceptible.

There are three types of heat-related illnesses:

• Heat cramps (the mildest form of heat illness) - consists of painful muscle cramps and spasms that occur during or after intense exercise and sweating in high heat
• Heat exhaustion (more severe than heat cramps) - results from a loss of water and salt in the body and occurs when the body is unable to cool itself properly (not enough fluid). If left untreated, it can progress to heat stroke.
• Heat stroke (most severe form of heat illness) - occurs when the body's heat-regulating system is overwhelmed by excessive heat. It is a life-threatening emergency and requires immediate medical attention.

Read on for the most common symptoms of heat-related illness. Specific treatment will be determined by your child's doctor and may include some, or more, of the following:
