I am 71 yrs old . I have always been hot when other people are cold. But it has gotten worse. I sweat when I am cleaning the house. Dripping sweat. If it's above 74 temp. I am hot. Sweat on hair line and back of neck. Friends say it looks like I just got out of the shower. Dr's have told me it's just my matablism. If there is a breeze or moving air it's better. I have a fan on me while watching tv. 74 temp. Is too high.
