Melatonin And Sleep

Sleep is a natural part of human life and an activity that any living human being has to indulge in. In fact, even the mentally ill who are believed to be able to go without sleep are brought down by it at one point or another. Contrary to what most people believe that sleep only has to take place at night, research has established that the cycle of sleep keeps alternating and does that sleep does not entirely have to take place at night. It can even occur successfully during the day. However, exposure to darkness and light regulates sleep in humans. It is said that exposure to light stimulates hormonal activity to make a person feel sleepy or awake.

The Brain And Sleep

In the brain, there is a nerve center called the Supra-Chiasmatic Nucleus (SCN) that works by starting signals to the other sections of the brain by controlling hormones, temperature of the body and other functions that also play numerous roles in making people to feel either sleepy or wide awake. The SCN works in the notion that once the body is exposed to first light every day, the clock starts to conduct various activities that will ensure that the person is awake like raising the temperature of the body and also the release of certain hormones that help in stimulating the body such as Cortisol. The clock also delays production hormones such as Melatonin that is associated with the onset of sleep until that time when darkness shall arrive.

Melatonin Is A Hormone In The body

Melatonin is a hormone that is part of the sleep and wake cycle of humans. However, it has to be noted that taking too much of the pill does not make one to sleep faster or even stay asleep for a longer period of time. The first step that everyone having sleeping problems should take is to consult a doctor or a physician. This will help in making the person fully understand the reason for the sleeping problem rather than going for Melatonin straight away. Melatonin is natural hormone that is made by a gland in the body known as pineal gland. The gland is shaped like a pea and found in the brain. The gland is only active during sunset when it is dark. When active, it stirs the production of sleep and wake cycle hormone by the SCN. As a result of this, the blood Melatonin level sharply rises and one begins to feel less alert thus prompting sleep.

Conditions That Slow Down Melatonin Production

Bright light also inhibits formation of Melatonin. However, for the person to be able to fall asleep, they will have to get to a darker surrounding to enable the formation of Melatonin that is sufficient to cause sleep. The hormone is naturally contained in certain foods and the reason it is sometimes sold as a dietary supplement. Taking a typical dose of Melatonin pill is able to elevate the blood melatonin levels up to 20 times normal. To be able to solve your sleep problem using melatonin, always use the correct dose at the right time of the day.
