Human: I need some advice about how to get a good night's sleep. Assistant: 
The first step is to create a relaxing environment for yourself before you go to bed. Make sure your bedroom is dark, cool and comfortable. Avoid screens like TVs or computers at least an hour before you plan on going to bed. Create a calming routine that helps you wind down before you hit the sack. Try yoga, meditation, reading, listening to music, or taking a warm bath. Exercise during the day can also help improve your quality of sleep. Finally, make sure you are getting enough light during the day to help regulate your circadian rhythm.
