Melatonin: The Regulator Of Your ZEN
Melatonin is secreted from the pineal gland deep inside the brain.
For more than a quarter-century, scientists have been intrigued by melatonin’s ability to coordinate the body’s physiological rhythms that help set the brain’s biological clock.
The principal factor affecting melatonin is light, which inhibits the secretion of this hormone. Darkness has the opposite effect from light, resulting in signaling to the pineal gland to increase melatonin secretion.
The normal cycles of melatonin production are altered due to factors including aging, medications, and light exposure at night.
While the long-term health effects of disrupted melatonin secretion are not yet fully known, some scientists have suggested that years of working nights could lead to adverse effects—even cancer.
Fortunately, melatonin supplements can safely and effectively restore balance to the body’s circadian rhythm of this important hormone—helping achieve a restful night’s sleep and keeping your biological clock ticking throughout a long, healthy life span.
Melatonin is known as the sleeping hormone, but it plays a bigger role in the body than most would presume.
Those with neurodegenerative diseases such as Alzheimer’s and Parkinson’s have decreased production of melatonin and receive advantages from supplementation. Melatonin does this by easily diffusing into cells and crossing the blood-brain barrier to protect against oxidative damage.
Obtaining sufficient amounts of quality sleep is an absolute necessity for good health, yet many of us experience sleep difficulties on occasion. Insomnia occurs due to a variety of factors—ranging from long hours of work or travel to sleep-disruptive conditions, such as urinary frequency and stressful events.
A large analysis revealed several of melatonin’s sleep-enhancing benefits.
Reviewing 15 studies of sleep in healthy adults, scientists noted that melatonin administration significantly reduced sleep latency (the amount of time needed to fall asleep), while boosting sleep efficiency (the percentage of time in bed spent asleep) and increasing total sleep duration.
Traveling to different time zones often leads to the fatigue and insomnia known as jet lag.
Supplementing with melatonin can help prevent or reduce jet lag, particularly when traveling across several time zones. Melatonin works by helping re-synchronize the body’s circadian rhythms, helping the traveler adapt to the local time
Individuals who work the night shift are often chronically tired due to difficulty falling asleep during the daytime.
Supplementing with melatonin has helped improve the length and quality of daytime sleep in these individuals. These findings demonstrate an important characteristic of melatonin: the hormone exerts its hypnotic (sleep-inducing) and sedative (anxiety-relieving) effects, regardless of dosage time.
To summarize, Melatonin is great for your brain and dosages are recommended at .3mg-5mg a day for safe and effective balancing of your body's circadian rhythm.
