The Federal Emergency Management Agency (FEMA) offers the following extreme heat survival and safety tips:
Drink plenty of water; even if you do not feel thirsty. Avoid drinks with caffeine, as this can contribute to dehydration. Persons who have epilepsy or heart, kidney, or liver disease; are on fluid-restricted diets; or have a problem with fluid retention should consult a doctor before increasing liquid intake.
Never leave children or pets alone in a closed vehicle – even on a “moderately warm” day. NHTSA highway safety experts remind us that it is extremely dangerous to leave children (or pets!) alone in a parked car in warm or hot weather “even for a few minutes.” When it is 80 degrees outside, it can get up to 114 degrees inside your car in just 30 minutes!
Check on family, friends, and neighbors whose homes do not have air conditioning and who may spend much of their time alone.
Check on your animals frequently to ensure that they have plenty of water and are not suffering from the heat.
Go to a designated public shelter if your home loses power during periods of extreme heat. Stay on the lowest floor out of the sunshine if air conditioning is not available.
