The sleep challenge continues. One participant noted that it was difficult to go to bed at 10 PM last night. It was as if their body was so used to staying up late that going to bed at a different time just felt odd. In fact, they reported sleeping worse than other nights.

Other factors, besides the time you lie down, affect how you sleep. This month we’ll spend some time on other factors. For now, let’s stay with this participant’s feedback. If you stay up later than 10 PM on a regular basis, you’ve trained yourself to stay up. That might seem like an overly obvious statement, but it’s true. Going to bed at a specific time is a habit. If you go to bed too late, it’s a bad habit. If you go to bed at a time that gives you optimal sleep and gives you max energy the next day, it’s a good habit. This challenge is all about a tiny habit that affects everything you do. Keep on going to bed at 10 PM (or earlier) and keep track of how you feel.

We’ve got 30 more nights to prove this out. If you didn’t quite make it last night, make a plan to be in bed at 10:00 sharp tonight.
