I over heat during the night when im in bed and have for as long as i can remember. now i am even waking up drenched in sweat when my partner is a completely cool normal temperature. is this actually okay if i have always been hot at night?

You should see a doctor as several endocrine diseases such as hyperthyroidism can cause this. Good Luck

Since these night sweats have been occurring for years and you have no fevers,chills,weight loss, or body aches & pains, they appear to be more of a nuisance than anything serious. I assume that you don't take medication like aspirin, Aleve, advil,Tylenol in the evening as these can occasionally cause night sweats. I'm sure your bedroom is not overheated& you don't use heavy blankets, bedclothes
