In a former time, I wrestled. Not that fake WWE stuff. Collegiate style. I used to be pretty good at it, too. Anyone who knows a current or previous wrestler will attest to the fact that wrestlers will do anything to lose that extra couple of pounds to make weight including, but not limited to wearing plastic bags, riding a bike in a sauna, skipping one too many meals and even shaving body hair. Things can get pretty desperate. But as one who has direct experience will tell you, few things will cause you to lose weight quickly except dehydration and fasting. Everything else is smoke and mirrors.
One particular wrestler friend shaved his head and the rest of his body in an effort to make weight. It quite literally did nothing to move the needle that was after his complete manscaping session, which included hair removal from his legs, chest, groin and head.
The same holds true for those looking to sacrifice their body hair by manscaping in an effort to have an impact on their heat coefficient.
A study entitled Hair Density, Wind Speed and Heat Loss in Mammalsgives similar conclusions as to why people do not get any cooler if they shave their body hair. The study indicated that the threshold for heat retention is somewhere in the range of 1,000 hairs per square inch of body area. Given that the average male might have 200 to 300 hairs per square inch of body area, we simply do not have the amount of hair necessary to make a meaningful impact on our body’s temperature.
So, before you go doing a complete manscape routine to your entire body thinking it is going to effect the temperature.
