Why does our body sweat?

• A. To stay hydrated
• B. To cool the body
• C. To gain energy
• D. To release toxins

Answer: (B)

Sweating cools the body by using evaporation to remove heat. When your temperature rises, sweat glands release fluid onto the skin. That liquid absorbs heat from your skin as it changes to vapor, so as it evaporates, your body loses heat and temperature drops. This is especially important during exercise or in hot environments, where metabolic heat and external heat can raise your core temperature. Hydration matters because losing too much fluid without replacing it makes cooling less effective. Sweat might carry trace amounts of minerals and waste, but its primary purpose isn’t hydration, energy, or detoxification—the kidneys and liver handle those roles.
