Products to help us sleep better

I struggle to get a good night sleep chronically. I am curious what products and ideas other chiarians have tried and tested that helps besides medications. I am posting some products that have helped me. If you suggest a product to buy, please include a pic with info on where it can be bought. Thanks!

I love mine, but i do have to soak the heating element in vinager every two weeks the hardwater deposits off of it. It’s pretty easy to clean (after I’ve soaked it for a couple of hours).
