Porfirio Villarreal with the Houston Health Department says people really need to take precautions against the high temperatures to avoid heat-related illnesses.

Villarreal says, "Heat exhaustion, usually associated with heavy activity, is the body's response to an excessive loss of water and salt contained in sweat. Signs include profuse sweating, paleness, muscle cramps weakness, dizziness, headache, nausea or vomiting, a weak-but-rapid pulse and fainting. The skin may be cool and moist. If heat exhaustion is untreated, it may progress to heat stroke."

Villarreal says heat stroke occurs when the body's temperature rises rapidly, the perspiration system fails and the body is unable to cool down. The body's temperature may rise to 106°F or higher within 10 to 15 minutes. 

Heat stroke can cause death or permanent disability if emergency treatment is not provided.

Villarreal says doctors recommend drinking more water, wearing light colored and loose fitting clothing.

Also, make sure you keep a close eye on children ages four and under. Also, check on the elderly.
