So, I tried to improve my sleeping habit by reading more books about health and sleeping. I basically summarized all of the points that I got from those books, tried them one by one, and keep what works for me. So far, my sleeping score has been improving to >80 and my face skin has become very moist and plumpy somehow, just by changing my sleep routines. It's a nice bonus lol. I still have some days when I found it hard to fall asleep and feeling not so well-rested when I awake, but as long as things are improving, 80% of good sleep and 20% of bad sleep, is good enough for me. Turns out it wasn't only me who have trouble sleeping. My own family and my close friends all have trouble sleeping. So, I shared them my tips, and here I post what works for me, I hope it helps a bit should you also have trouble with sleeping. Pls note that what works for me may not works for you, and you may have different things that work for you, so for complete info pls read books about health
