<human>: I'm having trouble sleeping lately. What can I do to get a good night's sleep?
<bot>: Try setting a consistent bedtime and wake up time each day. Make sure your bedroom is dark, cool, and quiet. Avoid screens at least an hour before bed. Exercise during the day, but not too close to bedtime. Reduce caffeine intake in the late afternoon and evening. Eat healthy snacks that are light and low-calorie. Get plenty of natural light exposure during the day.
