I am hot all the time. I cannot function in temperatures above 75 degrees for very long. I sweat profusely and can only clean house or work around the house for 30 minutes in 73 degrees and then I have to sit and cool off for 30 minutes. Could this be hormones? I am almost 72 and had a complete hysterectomy 30 years ago. I am also about 35 pounds overweight and think that might have something to do with it although I was hot when I was not 35 pounds overweight.
