9. Find The Balance Between Light And Dark
May sure you get outside in the sunlight every day. And don't think it has to be clear skies — just spending time in the natural light will signal to your body that it's time to be awake and alert. Additionally, make sure your bedroom is dark when it's time to go to bed at night. You can even start to dim the lights in the hour or so leading up to bedtime. If you live in the city where there is a lot of street light at night, maybe buy some blackout blinds to make your room extra dark.
