Drink blue water 

Fill a clear glass bottle or jar with water, and cover it with some translucent blue paper (such as blue cellophane, available at art supply and some grocery stores). Put the bottle in the sun for about 2 hours. Drink 1 to 3 cups of the water each day. This will have a cooling, soothing effect. Believe it or not, it works!

Drink aloe vera juice 

You might try drinking half a cup of pure aloe vera juice twice a day.

Keep your colon clean

Keeping your colon clean is important, in order to remove toxins from the body. You can easily accomplish this by taking the herb amalaki, ½ to 1 teaspoon daily, as a powder on the tongue. Take it before bedtime, and wash it down with warm water.

Apply Melon 

Rub some melon on the skin at bedtime, and leave it on overnight. It's cooling.

Berating Exercise

Breathing through the left nostril only for 5 to 10 minutes, will help reduce acne (This is called the Moon Breath and is said to be cooling). Simply cover the right nostril with your thumb, and breathe normally through the left side. If the nostril is blocked, don't force it, try again later.

Relax your face

Rub your hands together vigorously to create a bit of warmth and place both hands over your face for a couple of minutes. This will relax the facial muscles and increase the blood supply.

You can also rub your hands until the palms become warm. Then gently touch just the heart of the palm to the eyelashes.
