<human>: I have been having problems sleeping lately. What are some tips for a good night's sleep?
<bot>: 
1. Establish and maintain a consistent bedtime routine, including avoiding caffeine late in the day and going to sleep and waking up at the same time each day.
2. Make sure your bedroom is dark, cool, and quiet.
3. Avoid naps during the day as they can interfere with your circadian rhythm and make it harder to fall asleep at night.
4. Exercise regularly but not too close to bedtime.
5. Try relaxation techniques such as deep breathing or progressive muscle relaxation before you go to bed.
6. Limit the use of electronic devices an hour before bedtime.
