What you can do:
Check on elderly family members and neighbors to make sure they have a cool place to go if they have no air conditioning.
During extreme temperatures, fans by themselves are not enough to prevent heat related illnesses. Cold baths or showers can help cool you down. Drink cool, non-alcoholic beverages and increase your fluid intake, regardless of your activity level.
Never leave children or pets in cars. Temperatures inside a car can reach more than 150 degrees quickly, resulting in heat stroke and death.
Here are additional steps you can take to protect yourself against heat-related illnesses:
Keep cool in an air-conditioned area. Take a cool shower or a bath. Consider a trip to the mall or a local library or visit a friend with air conditioning. Spending at least two hours per day in air conditioning significantly reduces the number of heat-related illnesses. When temperatures reach the upper 90s or above, a fan may not prevent heat-related illness.
Drink plenty of fluids (2-4 glasses of cool fluids each hour.) To replace salt and minerals lost from sweating, drink fruit juice or a sports beverage during exercise or when you have to work outside. However, talk to your doctor first if you're on a fluid-restricted diet or medications, or on a low-salt diet.
Avoid sunburn and wear light clothing. Sunburn limits your body's ability to keep itself cool and causes loss of body fluids. Use sunscreen with a higher SPF. Lighter-weight clothing that is loose fitting and light colored is more comfortable during extreme temperatures. Use a hat to keep the head cool.
Give your body a break as the heat wave can be stressful on your body. Limit physical activity until your body adjusts to the heat.
Use the 'buddy system' if you're working outside. If you're working outside and suffer a heat-related illness, you could become confused or could lose consciousness. Therefore, make sure someone else knows of your plans.
