The pineal gland is controlled by the suprachiasmatic nucleus SCN. The SCN is a group of neurons, or nerve cells, in your hypothalamus.
These neurons control your body clock by sending signals to each other. During the day, the retina in the eye absorbs light and sends signals to the SCN. In turn, the SCN tells your pineal gland to stop making melatonin. This helps you stay awake. The opposite happens at night. As your melatonin levels increase, your body temperature and blood pressure drop. The melatonin also loops back to the SCN and slows down neuronal firing, which prepares your body for sleep.
Melatonin is quickly absorbed by the body. After you take an oral supplement, melatonin reaches its peak level in about 1 hour.
