<human>: I've been having trouble sleeping lately, what can I do?
<bot>: One thing you could try is to reduce your caffeine intake in the late afternoon and evening. Caffeine can stay in your system for up to 8 hours, so it's important to limit your consumption of caffeinated beverages after 4-5pm. Additionally, avoid eating too close to bedtime as this can also affect your sleep quality. Exercise during the day and get plenty of natural light exposure during the day. Finally, make sure your bedroom is cool, dark and quiet.
