The general belief in the 1950s was that sleep was just a passive activity during which the body and brain are inactive. However, different studies have proven that sleep is a period during which the brain is involved in a number of activities necessary to life. Neurologist Mark Wu and sleep expert John Hopkins both agreed that sleep is closely linked to the quality of life. Different other researchers after various hours invested in finding out about sleep, the process of sleep and how it affects the body system and surprisingly discovered that all sleep are not the same.
Studies have also revealed that throughout the period of sleep, the brain will cycle repeatedly in two various forms of sleep; the non-rapid eye movement sleep and the rapid eye movement sleep.When the body sleeps, the first part of the cycle it experiences is the non-rapid eye movement form of sleep. In this cycle, the initial stage is between being awake and falling asleep, and then in the second stage the heart rate and breathing are controlled and then the body temperature drops. In the other stages comes the most important stage of sleep which is the deep sleep. According to updated reviews on sleep, the non-rapid eye movement sleep is the most important sleep phase for learning and refreshing of memory.
When the body does not get enough sleep, it can be very disastrous for the immune system and bring about other disease causing conditions. Insufficient sleep can cause lowered sex drive, weaken your immune system, cause thinking concerns, and lead to weight gain. When there is inadequate sleep, there is also increase in the risk of certain cancers, diabetes, and even car accidents. Losing sleep can weaken the ability for the body to fight off disease making it a lot effortless to get sick. There are also higher chances of having coronary heart disease or even a stroke with less sleep.
Other mishaps that loss of sleep can cause to the body systems are major cognition or thinking issues, reduced sex libido, gained body weight that could lead to obesity, chances of increasing adult-onset diabetes, and an aged skin.
The body is regulated night and day or in sleep-wake cycles by a special hormone found naturally in the body. This hormone is known as Melatonin and it is produced in the body during dark hours to prepare the body for sleep. The presence of light decreases melatonin’s production and thereby a loss of sleep, it can also be a source of keeping the body aware and awake. Darkness makes the body to produce more melatonin, which acts as an indicator for sleep in the body.
Some people who have trouble sleeping have low levels of melatonin and may need an addition of melatonin supplementation to keep the body in shape. It is in contemplation that an addition of melatonin from supplements might help them sleep. Melatonin supplements are made synthetically in a laboratory and used as medicines. It is most commonly available in capsules and other forms that can be placed in the cheek or under the tongue this is to allow it to be absorbed directly into the body.
Melatonin supplement is generally used for loss of sleep or insomnia and improving sleep in various situations such as jetlag. It is also used to adjust sleep-wake cycles in people with shift-work disorders, it is very helpful in making the brain establish a day and night cycle.
FACTS ABOUT MELATONIN
Melatonin is a highly pleiotropic indicating molecule, which the body releases as a hormone in the pineal gland primarily in night. Age can considerably reduce the production of melatonin in the body; some other diseases like diabetes type 2, dementia, mood disorders, cancer, and severe pains can also cause a reduction in the production of melatonin in the body system. Melatonin dysfunction is most times related to deviations in phasing, timing, and amplitudes of circadian rhythms.
A common symptom of insufficient melatonin indicators is sleep disturbances. According to survey conducted in 2002 and again in 2007, however, melatonin supplement is the most sought after capsule for sleeping problems in about 1.6 million adults in the United States of America.
Melatonin is converted into serotonin, a neurotransmitter that is increased by some antidepressant medications.
USES OF MELATONIN SUPPLEMENT
Melatonin does more than persuade sleep, according to a research carried out by the University of Maryland Medical Center, melatonin also controls the start of menstruation, the length of ovulation cycles and menopause. Another study reportedly claim that supplements of melatonin are supposed to help bone loss and menopause symptoms.
Melatonin levels are also linked to cancer in a variety of ways. A detailed survey conducted by University of Maryland Medical Center on several number of women with and without breast cancer revealed that women with breast cancer naturally have lower levels of melatonin than women who don’t have it. Similarly, men with prostate cancer typically have lower melatonin levels than men without prostate cancer. Some studies done by the American Cancer Society on shift-workers with irregular sleep schedules revealed an increased risk of cancer in the workers. Melatonin is believed to have antioxidant effects and the ability to stimulate white blood cells, which attack cancer cells.
Sporadically, melatonin is used as a corresponding medicine in cancer treatment for breast, brain, lung, prostate, head and neck, and gastrointestinal cancer. Melatonin is sometimes used to tone down the side effects of chemotherapy, abate weight loss, nerve pain, weakness and a condition called thrombocytopenia.
A variety of other conditions are alleged to benefit from melatonin supplements including Alzheimer’s disease, tinnitus, depression, chronic fatigue syndrome, fibromyalgia, migraine, irritable bowel syndrome and epilepsy. Although there is no substantial amount of proof to back this claim up, some studies however, have professed it to be so.
Melatonin supplement manufacturers now produce melatonin in pill, liquid, chewable or lozenge form. Melatonin supplements are sold doses that can range from 1 to10 milligrams. Some dietary supplements contain so-called melatonin precursors, which are converted into melatonin in the body.
WHEN THE BODY NEEDS MELATONIN
The signs and indication the body gets when there is low level of melatonin in the body can sometimes be confused with the symptoms of other diseases, however, often times the body experience the following manner of discomfort it is seeking an increase in melatonin intake.
The first sign that is most times notice when there is little or no melatonin in the body is tense muscles at night and restless legs. Again if sleeping is a problem and one can easily wake up in the middle of the night and or have trouble going back to sleep, then there is certainly a deficiency in melatonin in the body.
Another cardinal sign for low melatonin could be dreamless sleeps, superficial or anxious sleep and anxious thinking at night. Although in this case however, the cortisol levels may also be to blame. In fact, cortisol and melatonin levels have an contrary relationship relative to each other in the body.
Lack of inner peace, constant anxiety, seasonal affective disorder or depression, always being on the edge with regards to emotions, and always irritable are also clear indication for low melatonin in the body.
Symptoms like hot flashes, heart palpitations, morning depression and irregular cycles usually experienced with menopause are believed to be improved by melatonin supplementation.
Melatonin is chiefly believed to be instrumental in converting the thyroxine (T4) to the active triiodothyronine (T3), and this gives the body energy and the ability to generate heat. In fact, melatonin and thyroid stimulating hormone all originate in the pineal gland, therefore, hypothyroidism symptoms may clearly indicate a low level of melatonin.
Melatonin can also be said to be missing when the body experiences intestinal problems such as pain, hyperactivity and intestinal spasms.
Melatonin supplementation has been shown to decrease the aging process in the brain tissues. This is simply because melatonin is a powerful antioxidant that helps protect all tissues in the body.
Several other studies have shown the benefits of melatonin in weight loss, cardiac function, breast cancer/prostate cancer prevention, mitochondrial function, improvement of stroke outcome, Parkinsons disease symptoms, high blood pressure, Alzheimer’s, fertility, type 2 diabetes, and immune function.
Supplementation with pharmaceutical grade melatonin can help, however, it is always advised to improve natural production of melatonin in the body at the right time of day; this can be made possible without supplementation.
Maximizing darkness at night the best way possible would be the best way for melatonin production to increase. This includes shutting off personal electronic devices when necessary. On the other hand, exposure to sunlight in the morning after sleep can also help the gland in melatonin production in the night. These steps are especially important as one ages since melatonin production drops off as the body gets older.
