The sleep tips so far have required adapting to new sleep schedules. When you first adopt a new sleep habit, like waking up at 6am every morning, you will struggle and feel tired. But keep it up for a while. It sometimes takes 7-10 days for a new schedule to “click”.
One older study followed six 8-hour sleepers for over a year. Once every 5 weeks the subjects reduced their sleep by 30m. Started at 8 hours, then 7.5, 7.0, 6.5, etc…
All subjects reported that every time they reduced sleep by 30m the first 7-10 days were difficult. But after 7-10 days their energy levels “clicked.”
