Melatonin growth hormone Video2-Minute Neuroscience: Melatonin melatonin growth hormone
Melatonin is a hormone made by the pineal gland.
The pineal gland is a small neuroendocrine gland at the base of the brain. It makes and secretes melatonin.
The secretion of melatonin is controlled by exposure to light. Melatonin may be a part of the diurnal cycle.
This is also known as the circadian rhythm. This is the regular cycle of wakefulness and sleep linked with day and night. Studies show above-average serum levels of melatonin in people with seasonal affective disorder SAD. This is a type of depression. Taking melatonih can shift the circadian hour clock by about 1 hour.
This makes up for 1 hour of jet lag. But studies show that jet lag due to travel through more than 2 time zones cannot be quickly corrected by melatonin.
Melatonin may help ease sleep disorders, such as insomnia. It may also help treat depression. It may improve how the immune system works.]
