Is it normal to not sweat a lot?
Depends.It depends
Yes, some people naturally sweat less than others. But if you barely sweat even in heat or during exercise, especially if you feel overheated, it’s worth getting checked.
Sweat levels vary a lot from person to person, so not sweating much can simply be normal for you. How much you sweat also depends on the temperature, what you’re doing, and how your body handles heat.
The important distinction is whether you can sweat when you need to cool down. If you’re getting overheated, dizzy, or unwell in hot conditions—or this is a new change—check in with a healthcare professional.
