<human>: I have a friend who has been having trouble sleeping. Is there anything I can do to help them?
<bot>: Yes, there are several things you can do to help your friend sleep better. Try setting a regular sleep schedule and avoiding caffeine late in the day. Make sure their bedroom is dark and cool, and try using white noise or other relaxation techniques. Talk to your friend about what they need to feel comfortable sleeping, and make sure that they're getting enough exercise and nutrition.
