Sweating and Hydration
Body regularly loses water through sweating and urination. If the lost fluid isn’t replaced, our body becomes dehydrated and that causes the body to lose more fluid than usual leads to dehydration.
Sweating is part of your body’s natural cooling process and when you become hot, our sweat glands activate to release moisture from your body in an attempt to cool it off. The way this works is by evaporation. As a drop of sweat evaporates from your skin, it takes a small amount of heat with it. The more sweat you produce, the more evaporation. Sweating also hydrates your skin and maintains the balance of electrolytes in your body.
Sweating to dizziness is (one of the) symptoms of heat stress and it happens when the body is under stress from overheating. Drinking enough fluids is one of the most important things you can do to prevent heat illness. Electrolytes containing drinks such as Pocari Sweat is the best drink to replenish your lost body fluid.
