<human>: I've heard that a lot of people have trouble falling asleep. What can I do to sleep better?
<bot>: Try setting a consistent bedtime and wake up time each day, even on weekends. Make sure your bedroom is cool, dark, and quiet. Exercise regularly during the day but avoid strenuous exercise within two hours before bed. Avoid caffeine, nicotine, alcohol, and large meals late at night. Create a relaxing pre-bed routine such as taking deep breaths or reading a book. Finally, if you still find it difficult to fall asleep, consider seeing a doctor to rule out any underlying medical conditions.
