This article will explain the role of melatonin in regulating your sleep cycle and the way it works.
What is Melatonin?
Melatonin, a hormone made naturally by your body's pineal gland, which is usually a a pea-sized gland located just above the center of the brain and other areas, like the eyes, bone marrow, and gut. Also known as the "sleep hormone", high levels of melatonin can assist you in nodding off.
Usually inactive during the day, when it's night, the hormone is actively produced and released to helps your body relax and sleep easily. This happens around 9 pm, when the melatonin levels within the blood elevate sharply and you start to feel less active.
These days, melatonin supplements such as Alvizia's Melatonin Alensleep sleeping pills are available among people facing problems insomnia, lack of sleep and fatigue. Additionally, melatonin is a strong anti-oxidant, which can provide a plethora of other benefits, including, treatment of stomach ulcers and heartburn, eye, and alleviating tinnitus symptoms. According to Johns Hopkins sleep expert Luis F. Buenaver, Ph.D., C.B.S.M. "Your body produces melatonin naturally. It doesn't cause you to sleep, but as melatonin levels rise during the evening it puts you into a state of quiet wakefulness that helps promote sleep,".
How Does Melatonin Work?
Melatonin works alongside your body's biological time.
Basically, the biological time is your body's internal clock working on a circadian rhythm. It allows you to know when it's time to sleep, wake and eat.
This hormone also helps control the temperature of your body, blood pressure and some hormone levels.
The levels of melatonin start to increase in your body when it is dark outside, indicating to your body that it's time to go to bed.
Melatonin also binds to receptors within the body and assists you to relax. To substantiate , melatonin binds to receptors within the brain to supress nerve activity.
Dopamine levels are also decreased that impedes with staying awake. Moreover, melatonin is also associated with the day and night cycle of your eyes. Even though the precise way melatonin aids you to sleep is unclear, as per research these processes can assist you to sleep.
Effect of bright light on melatonin
On the other hand, light suppresses melatonin production. It works in such a way that your body realises that it is time to wake up. Other than just adjusting the timing of the clock, bright light also has the effect of directly inhibiting the discharge melatonin. This is why it is often known as the "Dracula of hormones". Simply speaking, melatonin will not be produced during the day unless you are sleeping in a dimly lit, dark surrounding.
Melatonin and Sleep
Thus, as melatonin assists your body to go to sleep, people that don't make enough of it in the dark can struggle to nod off.
And there are many reasons which will cause low levels in the dark.
Stress, smoking, exposure to an excessive amount of light in the dark (including blue light), not getting enough natural light during the day, shift work and aging are among the primary and common reasons that supress melatonin production.
So, taking a melatonin supplement can help counter reduced levels and normalize your circadian rhythm. According to an analysis of numerous studies on people with sleep disorders, scientists revealed that melatonin helped reduce the time it took to nod off by an average of seven minutes. In many of these studies, people also reported significantly better quality of sleep.
Further, melatonin can also support people with fatigue ,which is a short lived problem.
People often experience jet lag, which occurs when your body's internal clock is out of sync with the new zone. Shift workers can also experience fatigue symptoms since they work during a time normally meant for sleep. Melatonin can help reduce fatigue by syncing your biological clock with the change in time.
For example, an analysis of 10 studies explored the consequences of melatonin in people that travelled through five or more zones. Scientists showed that melatonin was remarkably effective at reducing the effects of fatigue.
