I'm currently working on getting fit. And as always if I do a lot of something I wonder what unintended benefits there are. Those that drink beer and wine do this all the time.
So I was thinking, when you have a nasty virus or bacteria infection, one of the things your body does is raise the body temperature (fever). We believe this happens to make the body less hospitable for nasties that are sensitive to high temperatures.
I assume your body doesn't keep an elevated temperature all the time as a precaution because it would use a lot of energy which isn't an evolutionary benefit. I assume there are other negatives also.
The exception to the above however is when you do exercise. As you release more energy from your blood via work done by your muscles you also produce a lot of heat which our bodies try and get rid of. This is why you become a sweaty monster.
If you do exercise on a regular basis, does this repetitive increase in body temperature weed out nasties that are lurking inside of you ready and waiting for you to feel a little run down to take over?
In other words, does exercise help you fight off viruses and Bacteria diseases?
