The "sleepy hormone" is melatonin. This hormone is produced by your brain's pineal gland in response to darkness and plays a vital role in regulating your sleep-wake cycle, also known as your circadian rhythm.
Melatonin production is inhibited by light, which is why being exposed to bright lights at night can disrupt sleep. As darkness sets in, your pineal gland releases melatonin, signaling your body to prepare for rest. This hormone promotes drowsiness and helps you fall asleep.
Here are some key facts about melatonin:
- Production: The pineal gland, located in the center of your brain, produces melatonin.
- Trigger: Darkness triggers the release of melatonin.
- Function: Melatonin helps regulate your circadian rhythm and promotes sleep.
- Inhibition: Light inhibits melatonin production.
Melatonin is available as a supplement, which can be helpful for people with sleep disorders or those who travel frequently and experience jet lag. However, it's important to consult with a healthcare professional before taking melatonin supplements, especially if you have any underlying health conditions or are taking other medications.
