Disclaimer: I am not a medical professional. I can only speak to my own experience and hope that gives you some insight into what POTS is and how it can affect you or the people around you.
What it feels like: Sweating when you’re cold and not sweating when you’re hot. There are times when I don’t sweat for days and other days when I sweat a lot for no reason.
What causes it:
The best guess is the hormones that work to keep your heart rate up. Ephedrine and norephedrine are also responsible for making you sweat so that could have something to do with it. Otherwise, no one seems to know why.
Solutions I’ve found:
Keep an eye on your body temperature. For me I find I cannot regulate my own body temperature as well as others can. I sweat when it’s cold out and don’t sweat when it’s hot, this is not a good thing. Watching the temperature and keeping an eye on your body is your best bet to figure out the sweating. I have to say I haven’t tried to do a lot to stop sweating because it is such a minor symptom it’s not one that I worry about too much.
