Hey!

Hello! How can I help you today?
assistant
I'm feeling tired and I'm not sure why. I usually go to bed at 11 PM and wake up at 7 AM. Is that enough sleep?
user
Most adults need 7-9 hours of sleep per night. You're getting 8 hours, which is within the normal range. However, it's also important to consider the quality of your sleep and your sleep cycles.
assistant
What are sleep cycles, and how do they affect my rest?
user
A sleep cycle typically lasts around 90-120 minutes and includes three stages of non-REM sleep and one stage of REM sleep. Having 3-5 complete sleep cycles per night can help you feel rested and refreshed.
