Heat exhaustion is a form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids.
Warning signs vary but may include the following:
* Heavy sweating
* Paleness
* Muscle Cramps
* Tiredness
* Weakness
* Dizziness
* Headache
* Nausea or vomiting
* Fainting
* Skin: may be cool and moist
* Pulse rate: fast and weak
* Breathing: fast and shallow
To protect yourself from heat stress and heat stroke, follow these tips:
# Drink cool, nonalcoholic beverages. (If your doctor generally limits the amount of fluid you drink or has you on water pills ex. furosemide or hydrochlorothiazide, ask him how much you should drink when the weather is hot. Also, avoid extremely cold liquids because they can cause cramps.)
# Rest.
# Take a cool shower, bath, or sponge bath.
# If possible, seek an air-conditioned environment. (If you don’t have air conditioning, consider visiting an air-conditioned shopping mall or public building to cool off.)
# Wear lightweight clothing.
# If possible, remain indoors in the heat of the day.
# Do not engage in strenuous activities.
If you are living with or taking care of an older person
* Visit older adults at risk at least twice a day and watch them for signs of heat exhaustion or heat stroke.
* Encourage them to increase their fluid intake by drinking cool, nonalcoholic beverages regardless of their activity level.
Warning: If their doctor generally limits the amount of fluid they drink or they are on water pills, they will need to ask their doctor how much they should drink while the weather is hot.
* Take them to air-conditioned locations if they have transportation problems.
If You Don’t Have Air Conditioning:
• Take a cool shower, bath or sponge bath.
• Create cross-ventilation by opening windows on two sides of your house.
• Keep windows open at night.
• Keep curtains, shades or blinds drawn during the hottest part of the day.
• Cover windows when they are in direct sunlight.
• Electric fans may help, but when the temperature reaches the high 90s, fans won’t prevent heat-related illness.
• Go somewhere that’s air-conditioned like the shopping mall, the movies, the library, a senior center or a friend’s house. If you don’t have a car or no longer drive, ask a friend or relative to drive you. If necessary, take a taxi. Don’t stand outside waiting for a bus.
