Question

We sweat during summer and heavy exercise.

Answer 1

1. During summer, the environmental temperature is high, and heavy exercise also increases body temperature.
2. The rise in body temperature stimulates the sweat glands.
3. The sweat glands produce sweat (perspiration).
4. The sweat evaporates from the skin, removing heat and lowering body temperature.

Thus, we sweat during summer and after heavy exercise to regulate body temperature.
