If the weather is extremely hot:
- Stay indoors as much as possible and limit exposure to the sun.
- Stay on the lowest floor out of the sunshine if air conditioning is not available.
- Consider spending the warmest part of the day in public buildings such as libraries, movie theaters, shopping malls, and other community facilities.
- Circulating air can cool the body by increasing the perspiration rate of evaporation.
- If possible, avoid strenuous outdoor activities, particularly between 10 a.m. and 4 p.m. when the sun's rays are strongest.
- Use a buddy system when working in extreme heat.
- It may be uncomfortable, but wear loose-fitting, lightweight, and light-colored long sleeve shirts and long pants that cover as much skin as possible.
- Protect the face, eyes and head by wearing UV protective sunglasses, and a hat to protect your skin and corneas.
- Apply sunscreen with an SPF of 15 or more if you go out with exposed skin.
- Take frequent breaks and stay hydrated to prevent heat exhaustion.
- Eat well-balanced, light, and regular meals. Avoid using salt tablets unless directed to do so by a physician.
- Restrict or limit the number of caffeinated or alcoholic beverages you drink. These will dehydrate the body quicker. Drink plenty of water.
- Persons who have epilepsy or heart, kidney, or liver disease; or are on fluid-restricted diets; or have a problem with fluid retention should consult a doctor before increasing liquid intake.
- When on vacation or on a trip, take a supply of water in case you break down on the road.
- Check on family, friends, and neighbors who do not have air conditioning and who spend much of their time alone.
- Never leave persons or animals alone in closed vehicles.
