Chronic sleep deprivation is the larger issue. And how we really don't have treatments on how to fix that, and how ultimately sleep phase issues are a social issues (being forced to follow a fixed modern schedule). Not to mention how closely that's tied to ND people. So a lot of us deal with sleep issues since we were little, but work and school dont give us the flexibility we need. For example, flex hours could be helpful here. I would rather work 10am to 6pm or 11am to 7pm most days. Or 5-6 hours during the day and 2-3 hours late at night.
Sure we do, however, not everyone is willing to hike 20-30 miles a day and sleep in a tent. It's not practical but it is very effective.
People have natural sleep rhythms. Society should conform to that, instead capitalism demands we conform to what it deems profit maximizing.
