My partner has a current issue of sweating at night after he first goes to sleep, to the point where the bedding and myself are both soaked!!
It seems to be getting worse recently - think my arm is wet (not damp!) and any other body part which is touching him 
It usually happens within the first hour of sleep. He says He doesn’t feel like he is overheating or too warm. Last night after it woke us both up he got up and had a rinse before getting back in bed - he was fine after that but the sheets were still damp when we woke this morning.
It’s not too much as a problem for me, I’m just worried it’s something more. He’s generally healthy and very active, he doesn’t smoke or take any medication and no long term medical conditions. He is 28.
Has anyone else experienced this?
