The Miracle Hormone for Sleep, Appearance, and Health - Melatonin
Melatonin is often referred to as the "sleep hormone" and has been a topic of discussion for decades. But there is much more to this hormone than just promoting sleep. In this article, we discuss how melatonin "times" your sleep rather than keeping you asleep, why melatonin supplements should be used with caution, and how melatonin acts as one of the most powerful antioxidants in your body.
The Sleep Timer
Contrary to popular belief, melatonin does not keep you asleep; it acts as a biological seismograph that signals when your body needs to prepare for rest. During the evening hours (in the absence of blue light), melatonin production in the pineal gland increases.
Why Melatonin Supplements Are Often Discouraged
The natural production of melatonin is essential for a healthy sleep cycle, and the use of melatonin supplements is not without risks. Various negative aspects of supplementation include the development of dependence, inaccuracies in dosage, and possible side effects.
Regular use of melatonin can lead to a certain degree of tolerance. This means that the body adapts and needs a higher dose to achieve the same effect, which can lead to dependence in the long term. In addition, research shows that the dosage on the packaging of melatonin products often does not correspond to the actual amount of melatonin in the supplement. A study published in the Journal of Clinical Sleep Medicine has shown that some products contain up to 478% more, or 83% less, melatonin than indicated. Such variations increase the risk of side effects due to over- or under-dosage.
In addition to dosage issues, users also report various side effects such as daytime sleepiness, headaches, and dizziness. Melatonin supplementation can affect hormonal development, particularly in children, and there is an increased risk of interactions with other medications in the elderly (PMID: 10053496). For this reason, it is recommended that melatonin supplements only be used under strict medical supervision.
A Powerful Antioxidant
In addition to its role in regulating the sleep cycle, melatonin is also one of the most powerful antioxidants known to the human body. Oxidative stress caused by free radicals contributes significantly to the development of aging and various chronic diseases. Melatonin combats these harmful substances.
The powerful antioxidant effect of melatonin translates into various health benefits. For example, the hormone offers neuroprotective effects that are important in the prevention of neurodegenerative diseases such as Alzheimer's and Parkinson's (PMID: 36654092). Melatonin also contributes to the protection of cardiovascular health by reducing oxidative stress and inflammation levels. Melatonin also plays a protective role in the aging process by maintaining the integrity of mitochondria, which contributes to improved cellular energy balance and slows down the aging process.
Furthermore, research suggests that melatonin may be able to increase the effectiveness of chemotherapy and reduce the toxicity of certain drug treatments. The versatility and power of this hormone make it a valuable link in the protection against various conditions, ranging from cardiovascular disease to certain forms of cancer.
Practical Tip
In addition to the points already discussed, there are a few more interesting facts that will help you make the most of your natural melatonin production:
The effect of blue light on melatonin production should not be underestimated. Modern lifestyles, with lots of time spent in front of computer screens and smartphones, can disrupt the natural release of melatonin. Limiting exposure to blue light in the evening is therefore seen as an effective way to avoid disrupting your internal clock. Use blue light glasses to effectively block blue light without havingto giveup your screens.
