This can well be done completely at home. A person is made to sit on his chair with his clothes on and a blanket covering his whole body except the head, which is covered with a wet towel. A glass of water is served to the person before the bath.
Anybody can do it himself, if no aid is available. The ends of the blanket should fall on the ground to make one air-tight. All you need is two buckets and a kettle with hot water inside. The larger bucket should have tolerable hot water to cover the feet upto the ankles.
Place the feet in the bucket of hot water and keep your feet slowly moving in the water to get full warmth. As you feel that the water is losing heat, pour some hot water from the kettle into the bucket so carefully that your feet are not harmed.
Take out the same amount of water and throw it into the spare bucket, so that the level of water and its temperature is maintained. Repeat it, if necessary. The time-limit of this bath is 20 minutes.
You will begin to feel the effect of the bath in 10 minutes, after which your body will begin to perspire, as if you are bathing in perspiration. After 20 minutes of complete perspiration remove everything, wash your feet with cold water and make them dry with towel.
Lie down on a bed with a covered sheet, and let the remaining sweat in the body come out fully. Then rubbing off the sweat, you can have an ordinary cold-water bath.
This is a very strong bath and its effect lasts longer. Hence it is done once or twice a week only.
