Hi
user
Hello! How can I help you today?
assistant
I've been feeling really tired lately, and I'm wondering if my body has a built-in clock.
user
Yes, it does. Your body has a biological clock that regulates your sleep-wake cycle, also known as your circadian rhythm.
assistant
What controls my circadian rhythm?
user
Your circadian rhythm is controlled by a small group of cells in your brain that respond to light and darkness to synchronize your bodily functions with the 24-hour day-night cycle.
assistant
That makes sense. So, is it possible to reset my circadian rhythm if it gets out of sync?
user
Yes, it is possible to reset your circadian rhythm. Exposure to natural light, maintaining a consistent sleep schedule, and avoiding screens before bedtime can help regulate your biological clock.
