Overheating and dehydration during marathon can be prevented by wearing pre-cooling vests and drinking adequate amounts of fluids.

Dehydration is the excessive loss of water in the body. This can happen due to less intake of water, due to some disease or during heavy workouts. During workouts the body produces heat to burn the calories and therefore to cool down the body, water is released in the form of sweat.

Pre-cooling vests are the type of vests that can be wore some time before any physical activity. In these vests, there are various pockets present where ice packs can be stored. This delays the production of excessive heat in the body and sweating. The vests can be wore during warm-up but must be removed during excessive physical activities.
