I sometimes can’t sleep due to stress or sickness. So I have a book on my nightstand for this situation.
It is a field guide to trees in my area. It is very boring and I’m not retaining much of what I read at 3:30 a.m. The point is to sit in a chair and look at trees until I feel I can fall asleep again.
I often have that problem. I put on whatever history documentaries or podcasts that have smooth voices and slow down the audio, thru my earbuds and fall asleep that way. Works better than all that sleep sounds/ music ever did
Simon Whistler is basically my melatonin.
