How to use the wet pack?
Take the big cotton cotton, fold it into a long strip about 10 inches wide and 1 meter long. Dip it in cold water (Water should be as cold as you can easily bear. If your tap gives out cold water, that's good enough, otherwise you may use some ice), squeeze out the excess water and wrap it around your abdomen. Tuck it in so it doesn't fall off. Half the pack should lie above the navel and the other half should lie below the navel. 
Take the small strip, dip it in cold water, squeeze out the excess water and wrap around your neck. 
Take the other small strip, dip it in cold water, squeeze out the excess water and wrap around your forehead.
