Strenuous activities should be reduced, eliminated or rescheduled to the coolest time of the day; individuals at risk should stay in the coolest available place, not necessarily indoors.
Dress for Summer
Lightweight, loose fitting, light-colored clothing reflects heat and sunlight and helps your body maintain normal temperatures.
Drink plenty of water or other non-alcohol fluids
Your body needs water to keep cool. Drink plenty of fluids even if you don't feel thirsty. Persons who (1) have epilepsy or heart, kidney or liver disease, (2) are on fluid restrictive diets or (3) have a problem with fluid retention should consult a physician before increasing their consumption of fluids.
Do not drink alcoholic beverages
Do not take salt tablets unless specified by a physician
Persons on salt restrictive diets should consult a physician before increasing their salt intake.
Spend more time in air conditioned places
Air conditioning in homes and other buildings markedly reduces danger from the heat. If you cannot afford an air conditioner, spending some time each day (during hot weather) in an air conditioned environment affords some protection. Visit air-conditioned local public spaces such as shopping malls, community centers and libraries.
Don't get too much sun. Sunburn makes the job of heat dissipation more difficult
Reduce physically strenuous outdoor activity, especially between 11 a.m. and 4 p.m.
Never leave the elderly, children or pets unattended in a car
