@Kitcat122 and @Whatnext2018 yes me too at 3 or near enough. I asked because...
With all the connections that are being made to histamines and long Covid...
I was reading an scientific article that mentioned the body makes most of its histamine at about 3am.
Having been plagued at that time by various issues and very weird sleep / dreams etc I thought it was interesting when I read it.
Apparently histamines also effect the contraction strength of the heart muscle which results in a forceful heartbeat. A lot of people (myself included) are experiencing this at the same time.
However, I think the body does a lot in regards to hormones, blood pressure and who knows what else in the early hours?? so who knows!
Hopefully we’ll find out.
