Night Sweats combined with feeling cold when its really warm (in bed)

 

One that I notice (aside from being tired all the time) is that at night he is always complaining about being cold, even when its really warm.  Ie if its a summer night and its like 22 or more degrees centigrade and im so hot I cant even handle a sheet, he will be beside me with duvet and everything wrapped around him like he's trying to mummify himself and still complaining he is cold

 

yet in the middle of the night if i read out for him he is drenched in sweat

 

is this a common CFS thing? is there anything he can do to alleviate it?  It is like his bodys 'temperature guage' is telling him its cold even though its hot, so he reacts by putting on heaps of blankets etc, which makes him sweat because hes actually overheating his body.  But if he doesnt do that he is freezing cold.

 

Tonight he it telling me he has a heater on at his place and a load of blankets and he is shivering because he is cold

 

odd thing is - when we are up and about he will be wearing a tee shirt when I want to wear a jersey or even coat - when hes up his temperature sensitivity is pretty much normal.
