We often don’t think that being out in the sun could be a treatment for insomnia, but there are lots of benefits to getting a bit of sun!
I wonder if insomnia is just a modern day problem, or has it always been a human issue. Personally, I think insomnia is an epidemic in this day and age, and if it existed at all in ancient times, in comparison, I imagine it was a very low percentage! People throughout time have worshipped the sun for its power.
