No sweat
Hi

I don't seem to perspire a lot when I exercise. I spin three times a week I can feel that I'm working, my heart rate is where the instructor idicates it should be.
Am I doing something else wrong, could there be a medical reason for this?
I drink the recomended amount of water per day, does this have any effect?

Hi BB

Sweating during exercise is a tricky one. I can pretty much guarantee that if you didn't sweat, you would be almost completely exercise intolerant. In fact, there are people like this and they simply can't do exercise. So my suspicion is that you probably sweat less than most people, but still enough to lose heat. Remember that sweating has a very very important function in the body - it allows heat to be lost and so we should (in theory) sweat only enough to lose the heat. The truth however is that most people sweat more than this, and so the excess sweat, if it can't be evaporated, drips off. This is when we notice that we are sweating. In actual fact, we sweat a lot more than just the amount we see dripping off, but because it evaporates, we don't notice it - it is actually called insensible perspiration.

So I would say that you have nothing to worry about, as long as you can exercise, you are sweating enough, it just so happens that you are evaporating your sweat.

Good luck
