My husband is a atheletiv runner, normally healthy, he even had his blood tests done a couple of months ago (full blood count) apparently everything normal, this is the second night he has woke up drenched in sweat out the blue. He is very very slim and it’s winter and my bedroom is not hot at all. He doesn’t wear pjs at night. He has requested more blood tests but please is there anyone out there who can reassure me. I’m heavily pregnant and being from a family in healthcare, a 36 yr old starting to get nightsweats in winter isn’t a good sign. Worried sick, thank you in advance.
