Question

we sweat during summer and heavy exercise give reason?

Answer 1

As we work out as a result sweat release from your body.

Answer 2

So it makes sense that a particularly tough run or strenuous pick-up game ups the body's temperature and the need to sweat it out. ... But it's not just body temperature that causes sweating. During exercise, heart rate and blood pressure increase, which in turn cause the body to pump out more sweat
