Sleep is a fickle thing. I think some sleep habits are programmed into us when we are young (theory based on anecdotal observation with my kids and talking with others over the years). That said, having a shut down process and consistent schedule is really important. Getting rid of blue light, not eating several hours before bed, relaxing with less stimulatong activity, taking some Melatonin. Melatonin is not habit forming really works well for most people based on sleep studies. You still need the shutdown process, and then Melatonin boosts you into a sleep state. Excercising is also important for setting up good sleep. I think this is all most people need to do if they just have minor trouble falling asleep. Moderate to severe sleep issues can be symptoms of something else.
