Other than walking your dog, the activities you list are sedentary. I sleep best when I am mentally AND physically exhausted. For that to happen, I walk my dog extra times (he loves it more than I do, but at least I get to see him enjoy himself); work out with an online exercise video, in an in-person tai chi class, or with equipment I have handy; do housecleaning, including organizing/reorganizing closets (anything to keep me on my feet), and extensive yard work. I used to force myself to do these things; now I know how worthwhile it is to be up and out and about. I volunteer to help others with yard work, pick up litter in the area, etc. Talking with others outside is always a boost. Physical activity gets me "out of my head" better than anything. I don't sleep during the day and night-time sleep is usually interrupted, but if I can get 5-7 hours, that's great. I urge you to try to physically exhaust yourself (provided you have no physical limitations to do so).
