Your body tries to maintain a body temperature of 98.6F.
Your body has two main ways of handling temperature changes that can occur. If you become too hot, your body triggers the sweat glands. If you become too cold, your body triggers your muscles to shiver.
Sweat, is your body's way of cooling itself. I think after 3 games you should be soaked.
It's normal and healthy to sweat a lot after sports, if anything it's unhealthy not to sweat. People who sweat more (not excessive sweating) have healthy circulatory systems, are well hydrated and their bodies are releasing all the toxins. The more you sweat the longer you can play and endure. There are weird myths that apparently only overweight people sweat a lot, but that's not true. Overweight people can sweat very little during physical activity and skinny people can sweat a lot and vice versa, it all depends on how fit your lungs and heart are, for example someone who is more fit will have the ability to produce more sweat to cool the body down faster than someone who is not as fit. But of course, you also have to remember that medical conditions can cause true excessive sweating, which is usually a lot worse than what you are experiencing.
As an athlete, my sweat tells me a lot about my health. When I drink tons of water, am healthy and hydrated it encourages my body to release way more sweat than usual, but the sweat has no smell. When I drink lots of water, my sweat never has a strong smell but there is a lot of it.
When I'm dehydrated and haven't detoxified in a while, then what little sweat I do produce tends to smell.
When I am lacking carbs, I sweat excessively in a bad way and it smells like amonia/cat ****/vinegar. That foul odor is ketones and is a bad sign that your body is starting to use protien (break down your muscles) as a fuel. So if this is happening to you, an easy fix is to eat some carbohydrates. For me, it goes away within an hour or so after eating carbs. Playing for 3 hours non-stop is a little excessive and can cause excessive sweating caused by ketosis if you have a fast metabolism like me (not eating enough carbs) and that isn't a good thing. If you are healthy, there really shouldn't be a terrible smell to your sweat. The smells are toxins being released, which is good, but if you sweat regularily, keep well hydrated and eat properly, you shouldn't smell bad when you sweat at all.
Excessive sweating can also be caused by medical problems like Diabetes and thyroid problems, so if you have any doubt, go see a Doctor, but typically excessive sweating seems to be classified as a health issue when it is much more excesssive than your case, for example, some people complain of excessive sweating when they are not working out at all and it becomes a very embarassing problem for them.
Very informative. Thank you both for your replies.
Have you tried eating chlorophyll? You can test this out by eating lots of parsley. Or you can buy chlorophyllin pills. Chlorophyllin is the water soluble derivative of chlorophyll.
