Is insomnia hereditary?

In the sense that a good many people make babies when they can't sleep, yes

Good question, I need to sleep on it

Not exactly. Stress-reactivity is genetic, so if you come from a family that tends to stress out a lot, then you are also likely to easily stress out. That stress can cause insomnia.

I think susceptibility to it might be hereditary.

oh no its something to do with DNA ..........🤔

Lol you and me both luv
