Interesting.........I do not sweat either. I used to work in a health and fitness club where we had free use of all the facilities. I used to have a sauna every week and never did sweat so they nick named me reptile.
I did read someone recently relating Acetylcholine levels and sweating or rather not sweating???
Do you have any muscle weakness????????????
Did an extensive medical literature search, and could not find anything regarding cholesterol and perspiration. Everyone is different, someone people just don't sweat at much as others. As long as you're in good health, and have no personal or family history of autonomic problems (abnormal heart rate, blood pressure response to positional changes, digestive problems, abnormal tearing and salivation, impotence, etc...) then it's ok if you don't sweat after exercise. Now if those symptoms are a part of your life, then there may be an autonomic system problem present, otherwise I think you're fine.
In terms of exercise, you should use heart rate to guide you rather than extent of sweating. One simple is guide is to subtract your age from 220, which would be 185 in your case and use that as your maximal heart rate during exercise. If you're just starting, get up only t0 about 60% of that and then work up to 85% maximum heart rate. As for diet, use common sense and eat a balanced diet with more fresh fruits and vegetables. Stay away from fried and fast foods. Soy products (soy milk and tofu) as well as fish oil can also be helpful. Talk to your PCP about your cholesterol as medication to help lower your cholesterol and LDL may also be considered. Good luck.
You didn't mention your height. I don't really think that your not sweating is related to your cholesterol. Do you eat a lot of salt, Do you drink enough water My thoughts are that there might be something wrong with your internal thermostat. Have you had your thyroid checked When you exercise and don't sweat, do you get overheated, red faced can't get rid of the heat Are you cold a lot What is your resting heart rate I've always had trouble sweating when exercising as well and I have Grave's disease - a thyroid disorder.
if your not going to the restroom every couple hours, or sweating during exercise then you could be dehydrated, drink lots of water.
