Cooling down in hot weather is important for our health and comfort. Severe heat waves have become more frequent, and this trend will continue for a long time because of global warming.
You can effectively cool down your body by either giving your feet a cold-water bath or by wetting your scalp with cold water. The water needs to penetrate through the hair to the scalp to be effective. In this way we can lower our use of air conditioning which helps to reduce global warming.
