Endocrinology experts explain that sleep plays an important role in weight loss. However, it is not possible to state that the use of melatonin itself helps to lose weight. What happens is that during quality sleep, the body regulates the hormones related to satiety (ghrelin and leptin). When one sleeps little or has poor quality sleep, these hormones also act in a worse way, causing the person to eat more until they are satisfied. That is, those who sleep better can control their weight more efficiently, and melatonin can be combined in this process. However, factors such as a balanced diet and physical activity are also determinants in weight loss, as much or more than a good night's sleep.
Benefits of melatonin in study
In addition to its sleep benefits, researchers have looked at other health uses of melatonin. Here are some lines of research: Migraine treatment Recent studies, some done here in Brazil, show the uses of melatonin in the treatment of some specific types of migraine. It has been studied for cases in which patients do not respond to common treatments, which include the use of painkillers, among other therapies. But it is not yet known what effect it can have in these cases, nor has a protocol for its use been established. Improved response to chemotherapy Some studies in mice have shown that melatonin can help increase the effectiveness of cancer treatments using chemotherapy. Studies are still being done in humans, but it is not yet known whether this hormone will act in the same way. Cancer prevention Some scholars go further and believe that melatonin can influence the prevention of some types of cancer. There are biological arguments for this since one of the body's processes during sleep is precisely to regulate the mechanism that controls whether the new cells created by the body are functioning as they should, preventing the appearance of tumors. But tests on humans are still being done and it takes a few years to reach a more concrete conclusion.
