The Impact of Melatonin on Human Health


Melatonin is a hormone naturally produced in the human body that regulates sleep, wakefulness, and other physiological processes. It is primarily synthesized and secreted by the pineal gland, a small endocrine gland situated inside the brain. While scientists are still uncovering the myriad roles melatonin plays in our body, its main purpose is to send signals to the body telling it when it’s time to shut off and when it’s time to wake up.

In addition to sleep regulation, melatonin is believed to have many other health benefits including anti-aging properties and reducing inflammation. Studies have shown it may help reduce the risk of some cancers, reduce bone loss and even boost the immune system. It also shows promise in treating anxiety, depression and bipolar disorder, insomnia and jet lag, and even fibromyalgia.

Melatonin can also regulate hormones, including hormones associated with stress. Chronic stress weakens the immune system and increases the risk of chronic diseases. Melatonin works to help reduce stress hormone levels, thereby reducing the risk of chronic diseases.

Melatonin also has antioxidant effects, helping to protect the body from damage by free radicals. Additionally, melatonin appears to decrease oxidation of lipids, which has been tied to the development of coronary heart disease. Further, melatonin has been linked to anti-cancer properties as it has been shown to reduce the growth of some cancer cells in laboratory studies.

The impact melatonin has on human health is extensive. Its ability to regulate hormones, combat inflammation, reduce stress, and provide antioxidant protection are just part of the many health benefits associated with supplementing with melatonin. However, it is important to note that more research is needed to fully understand the effects melatonin has on our overall health and wellness. Additionally, as melatonin supplements have gained popularity, it’s not recommended to exceed the recommended dose as this may have negative effects on health.

Melatonin supplements are a form of a hormone derived from the pineal gland in mammals. Melatonin helps regulate our sleep-wake cycle, known as the circadian rhythm, in reaction to shifts in light and dark environments. Melatonin supplements are available over the counter with no need for a prescription. This makes the supplement popular among people seeking treatment for sleeping disorders, particularly those suffering from insomnia.

Melatonin supplements are usually provided in capsule, tablet or liquid form. The highest recommended dosage is 9 milligrams (mg) for adults. Improperly dosaged administration of melatonin may result in an increase in one’s anxiety level or result in other unwanted effects like headaches or sleep paralysis. When taken within an recommended dose, some benefits of the supplement for adults include a reduction in the amount of time it takes to fall asleep and an increase in the quality of sleep one experiences overall. It may also provide relief from jet lag and schedule-related sleep interruptions.

Despite its use as a sleep aid, melatonin should not be taken as a substitute for a healthy lifestyle, where physical activity and adequate rest should be pursued. In addition, it should be noted that melatonin can interfere with blood pressure and diabetes medications, as well as other forms sedative prescriptions, so a doctor should be consulted before beginning its use.

Despite the potential side effects, melatonin supplements are generally considered safe and effective form of sleep aid. The supplement may be particularly useful for those who suffer from insomnia or general sleep troubles related to scheduling, lifestyle or environment regulation. 2016 Duke University Medical Center research has even gone as far to suggest that short-term use (under three months) of melatonin might be helpful for addressing sleep issues within the elderly.

Overall, melatonin, when taken responsibly and within the recommended dose, may provide health benefits for people of all ages that suffer from difficulties related to their sleep patterns and circadian rhythms. Due to its availability without a prescription, it has gained popularity as a form of self-care, though the public should always consult with a doctor before introducing a new supplement into their lives.
