Heat Exhaustion

 What it is: If you play too hard in the summer heat and humidity and take too few breaks for nonalcoholic liquid refreshment, you may feel faint, nauseated, and headachy.
 
 What to do at home:
 

• Stop what you're doing and rest in a cool, shady area.
• Spritz yourself with water and sit in front of a fan.
• Sip a sports drink to replace fluid and electrolytes. Or mix juice with a little water, or add 1/4 teaspoon salt to a quart of water. Avoid caffeine and alcohol.

 Seek immediate help:

• If you can't keep fluids down or if you start to feel confused. You may be developing potentially deadly heatstroke. Other signs include delirium or unconsciousness, hyperventilation, muscle cramps, and a temperature of 102 degrees or more.
