Night Sweats in Winter

Hi there, I'm having an issue with night sweats specifically in winter and autumn. I've always been a sweaty person but recently I've found that when its cold I sweat SIGNIFICANTLY more than normal. I'm waking up multiple times a night with sheets soaked in sweat.

I (25 FTM, taking testosterone) am hesitant to saying its medications. I do take several medications known for increasing sweating (testosterone and venlafaxine 150 mg) however the fact that its specifically in cold weather is bizarre. Neither medication is new. I am overweight, 100 kg and 178 cm, but again its just in cold weather.

Honestly I'm kind of losing my mind here, any ideas at all?
