Question

Why do we sweat more on a humid day?

Answer 1

• In hot dry summer days the temperature of our body is high, and as a mechanism of cooling our bodies, we sweat and since the atmosphere around are bodies is dry (less amount of water vapour is present), the sweat evaporates, and thus, lowering our body temperature.
• In hot humid days, sweating occurs​ because sweat does not evaporate easily in humid weather, as the air already has enough water vapor in it.
• As a result, sweat remains on the skin and the body does not cool down efficiently, unlike during hot, dry days when sweat quickly evaporates from the skin.
