#Melatonin #work
Melatonin is a natural hormone produced by the pineal gland, a small gland in the brain. It is crucial in regulating the circadian rhythm and the sleep-wake cycle. Melatonin production is closely related to exposure to light – its level increases in the dark and decreases in the light. Due to this, melatonin is often called the “sleep hormone”. In recent years, it has gained popularity as a dietary supplement, especially in the context of sleep problems and adjusting the circadian rhythm, for example when changing time zones.
How does melatonin work?
Melatonin has many functions in the body, but its main task is to regulate the sleep-wake cycle. When it gets dark, the pineal gland begins to produce melatonin, which signals the body that it’s time to rest. In turn, in the morning, when light begins to reach the eyes, the production of melatonin decreases, which helps you wake up and start the day.
The mechanism of action of melatonin can be divided into several stages:
- Light signal: Light reaching the retina of the eye is converted into a nerve signal that reaches the pineal gland.
- Melatonin production: In response to a decrease in light, the pineal gland begins to produce melatonin.
- Effects on the body: Melatonin affects receptors in the brain, reducing the activity of neurons responsible for wakefulness and increasing the activity of those responsible for sleep.
- Regulation of circadian rhythm: Through its activity, melatonin helps synchronize the internal biological clock, which is crucial for regular sleep-wake cycles.
Who needs melatonin?
Melatonin may be helpful for different groups of people, depending on their specific needs and health concerns:
- People with insomnia: Melatonin is often used as a sleep aid for people suffering from insomnia, especially those who have difficulty falling asleep.
- Travelers: For people who frequently travel between different time zones, melatonin can help adapt to new times by alleviating the symptoms of jet lag.
- Shift workers: People who work shifts and have irregular work and sleep hours may benefit from melatonin to regulate their circadian rhythm.
- Seniors: As we age, the natural production of melatonin may decrease, leading to sleep problems. Melatonin supplementation may be beneficial for older people.
- People with circadian rhythm disorders: Some conditions, such as delayed sleep phase syndrome, may require melatonin supplementation to improve sleep quality.
