Drink lots of water to regain the water lost due to sweating.
Stay in the shade. Read a good book, sit still or take a nap.When
you move around you will get hotter and hotter
Open the windows to let in a breeze. Use screens to keep out insects if they are a problem.
Go swimming. If you can, select a shady body of water.
Have a cold shower or bath. Even a small amount of water sprayed or splashed on you can help. Or try a face washer dipped in cold water and held against your face and forehead for instant cooling relief. Wet towels if you need to cool all of your body and wrap your legs, torso and arms with them.
Wet your hair with cold water every half an hour.
Use fans. Fans keep the air circulating and produce a small cooling effect. Place a wet face cloth on the fan to produce a mini air-conditioning effect. Be careful to sit the wet face washer only on the outer cage part of the fan so that it cannot be caught by the fan blades and do not leave the room without taking it off.
Try and get used to the heat. Try to do this without relyi
ng on fans too much. That way, you can be more independent of relying on any electrical equipment, something that become very important should there be a summer blackout.
Apply lots of sunscreen throughout the day. The protective function of such lotion only lasts for a few hours and less when you are in water. Reapply frequently for best coverage. Do not rely on it alone, however. Always combine with wearing a hat, long-sleeved clothing and keeping out of the sun during the hottest part of the day.
Consider running through sprinklers.
Wear a hat and don't expose too much skin. Long-sleeved shirts made of cotton, hemp and other natural fabrics will help deflect the sun's rays and protect your skin. A broad-brimmed hat is essential to protect your face and to create some shade over your head.
Keep inside or in the shade when the sun is at its height. Don't go outside if you can help it between 11 o' clock and 3 o' clock, as these are the hours during which the sun is at its strongest.
Use a washcloth. Get a washcloth and soak it in cold water . Barely ring it out, and lay it on your neck . Repeat when needed .
Run the insides of your wrists under cold water. If your major veins are cold or warm, your body is cold/warm.
Get a bag of ice. Put it on your forehead for 30 minutes.
Chew on ice cubes. Its just like drinking water, only colder!
When you go outside repeatedly spray yourself with cold water from a spray bottle. It keeps you cool and feels good.
Every half a hour, you can take a cold wet napkin and put in on your head for about 5 min. or so. It relieves the heat going to your head - and feels good!
