I have dizziness sometimes best thing to do is drink water it really helps

I sweat all the time. I carry a small towel with me because it gets really bad if I have an appointment and I’ve never been there before. It stresses me out. When I’m at home my husband is saying it’s cold and I’m sitting in same room with sweat pouring down my face and back with a fan on and my towel in hand. It could be because I’m at a certain age and they say you may sweat a lot but I’m not sure because this has been going on for 10 years.
