Wondering why you’ve been sweating so much of late? We tell you about the possible reasons and give you the science behind how it happens
As the weather gets hotter, you’re bound to sweat more, even if you’re doing the same things you used to during cooler months. So, while you can blame it on the heat, that’s not the only reason you may be sweating more than usual. But, if you’re rushing to work or an important meeting, the last thing you want is annoying sweat stains. So, if you were wondering what all the fuss is about and why you may be sweating more than usual, we’re telling you.
Why we sweat
Sweating is the body’s way of maintaining its temperature. In fact, the cells of your body need to be within a very narrow temperature range to function properly. So, it’s natural to sweat more on a hot day. While it may not be very efficient if the sweat doesn’t cool you down, it’s your body’s way of dealing with the increase in temperature.
Reasons for sweating
Quite obviously, the external temperature is one factor that controls sweating. The higher it is, the more you tend to sweat. Another factor that leads to sweating is exercise. When you exercise, your body temperature increases and your sweat glands start working to produce more sweat. Even walking is exercise for the body and can increase your body temperature, causing you to sweat. You could also sweat more than usual if you have a fever, or if you’re anxious, nervous or stressed out. Besides this, a condition called hyperhidrosis causes people to sweat excessively. Sufferers will sweat even when there is no need to; their body’s sweat glands don’t shut off, which causes the excessive sweating (even in an air-conditioned room!).
How your body produces sweat
You have millions of sweat glands in your skin, and each consists of a long, coiled hollow tube in which sweat forms and collects. A long straight section of this tube rises to the surface of your skin where it terminates. As the temperature of your body rises, you nervous system triggers your sweat glands, the convoluted part of which contracts and straightens, pushing sweat to the surface of your skin.
