Melatonin Magic!
What the heck is a pineal gland and what does it do? So glad you asked! The pineal gland is a magical friend deep inside your brain that releases melatonin, which helps regulate your sleep-wake cycle.
What's extra cool about the pineal gland? Even though it's deep inside your brain, it can detect light and knows the difference between day and night. How? Because light travels through the eyeballs, goes inside your brain where the pineal gland can "see" the light! Isn't that amazing? This magical melatonin gland was believed to be the third eye and the seat of the soul by many people, including philosopher Descartes. Learn more about the pineal gland on our YouTube channel! Sweet dreams.
