Very intense sweating during sleep

M33, 67kg , 185cm , smoking weed and tabbac, no alcohol , no drugs or medication

My husband is sweating incredibly while sleeping. Day or night, nap or long sleep , cold or warm, always. He sometimes has a migraine, have no idea if that's related. He sweats so much that we need to change the bedding daily and the matress can't dry out for hours and hours. He is not losing weight but can't gain either. Eats just normal , has an active way of life, very active job. Drink a lot of soda which I find bad, barely drinks any clear water.

Thanks in advance !!
