Are you sure about people dying from lack of sleep ? I read the opposite but I lack proof. To me sleeping is an essential "maintenance" of the body & the mind but that lack of sleep wouldn’t kill you in itself.
However there is no doubt sleeping is essential to psychological and physical health.
I also sometimes struggle with insomnia and I recommend reading "Why we sleep". It helped me understand sleep better than I would have thought and it actually helped me manage insomnia. The book is also actually really captivating which is a good thing given I thought I knew enough about sleep hygiene. I was so wrong.
