Did you know the hormone that aids in falling asleep also has benefits for heart health, aging, and possibly Alzheimer's prevention? While melatonin is primarily known for its sleep-inducing properties, recent research indicates it plays a significant role in overall health and longevity. Let's explore the unexpected ways melatonin is emerging as a crucial factor in maintaining wellness.
Overview
Antioxidant Powerhouse: Melatonin is a potent antioxidant, surpassing vitamin E by 200%, which helps reduce the risk of age-related conditions like macular degeneration, heartburn, and oxidative harm.
Heart Health Support: Melatonin aids in lowering LDL cholesterol, increasing HDL levels, and shielding the heart from post-heart attack damage.
Cognitive Protection: Melatonin can delay the onset of Alzheimer's by safeguarding neurons from oxidative damage during the initial stages of the disease.
Sleep And Melatonin
Readers familiar with this newsletter will recall our emphasis on the crucial role of adequate sleep in maintaining good health. Insufficient sleep not only affects energy levels and productivity but also heightens the risk of various diseases such as high blood pressure, diabetes, dementia, and even cancer. Melatonin, a hormone that regulates our internal body clock, signals the approach of bedtime. Due to various factors, our bodies may have insufficient levels of this hormone produced in the pineal gland of the brain. Hence, it's no surprise that melatonin supplementation has become popular among those deprived of sleep.
You may be aware of the significant impact of this essential sleep hormone, but its benefits extend far beyond promoting restful sleep.
Recent research on melatonin has piqued the interest of scientists who are uncovering its potential in addressing heart disease, diabetes, and other age-related conditions.
The decline in melatonin production with age has long been recognized by experts.1 This decline not only contributes to the aging process but also compromises overall health.2
For years, the mechanisms underlying melatonin's anti-aging effects remained uncertain. However, ongoing research is shedding light on its role in combating the aging process.
Here are three noteworthy discoveries:
#1 Defends against free radicals:
Melatonin's antioxidant properties have been a subject of fascination for scientists since its discovery half a century ago. Studies reveal that melatonin boasts 200% more antioxidant potency than vitamin E.3 Moreover, melatonin outperforms glutathione, as well as vitamins C and E, in reducing oxidative damage.4 This makes melatonin a superhero in combating diseases caused by free radicals.
Melatonin's antioxidant properties have unexpected applications, such as lowering the risk of eye conditions like age-related macular degeneration (AMD).5
In a study involving 100 AMD patients taking three mg of melatonin daily for six to 24 months, researchers observed a protective effect on the retinas, delaying damage from AMD.6 (Note: This dosage is substantial, more details to follow.)
Another study investigated the use of melatonin in treating stomach ulcers and heartburn. When combined with Omeprazole, a common GERD medication, melatonin accelerated the healing of stomach ulcers in participants.7 (Caution: Avoid the use of GERD medications.)
#2 Heart helper:
Over the past decade, researchers have closely examined melatonin as a cardio-protective agent. Animal studies indicate that melatonin's antioxidant prowess shields against heart muscle damage post-heart attack by minimizing injury.8
Human studies have shown that melatonin can reduce total cholesterol and LDL levels while elevating HDL cholesterol levels.9
#3 Delays Alzheimer's Disease:
A unique attribute of melatonin is its ability to traverse the blood-brain barrier. Its potent antioxidant properties are particularly valuable in combatting nervous system and neurodegenerative disorders.10
Melatonin can delay the onset of Alzheimer's disease and safeguard essential cellular structures from oxidative harm and degeneration. Interestingly, while melatonin may be beneficial in the early stages of Alzheimer's, its efficacy diminishes in advanced stages of the disease.11
My Takeaway
It is a well-known fact that melatonin levels decrease with age. Before resorting to supplementation, I recommend stimulating your body's natural melatonin production. This can be achieved easily by exposing yourself to sunlight in the morning, a practice that triggers melatonin production at night when it's most needed. Additionally, refrain from looking at screens for an hour or two before bedtime and ensure complete darkness in your bedroom during sleep hours.
If considering a supplement, start with a low dose (0.5 milligrams) and take it within half an hour of bedtime. Many supplements contain higher doses, so caution is advised. Gradually increase the dosage if needed until you find the optimal amount for improving your sleep quality. Remember, more is not always better.
While most individuals tolerate melatonin supplements well, there is a possibility of mild side effects like headaches, nausea, and dizziness, especially when combined with other medications. High doses may lead to insomnia.
Furthermore, prolonged use of melatonin supplements can further suppress the body's natural melatonin production. It's advisable not to use them long-term without guidance from a trusted healthcare provider.
For many individuals, enhancing melatonin levels naturally through sunlight exposure during the day and complete darkness during sleep is the first-line approach. Supplements should be considered a last resort.
Summary
Melatonin, the hormone responsible for regulating sleep, is gaining recognition for its significant health benefits beyond promoting rest. Research illustrates that melatonin's antioxidant properties can combat free radicals, support heart health, and potentially delay the onset of Alzheimer's disease. Despite a natural decline in production with age, simple lifestyle adjustments like morning sunlight exposure and screen avoidance before bedtime can enhance melatonin levels. While supplements can be beneficial in moderation, their use should be approached cautiously and as a final option.
Frequently Asked Questions
What is melatonin, and what does it do?
Melatonin is a hormone produced by the brain that regulates sleep and offers powerful antioxidant benefits for heart and brain health.How can melatonin protect against Alzheimer's disease?
By crossing the blood-brain barrier, melatonin protects neurons from oxidative damage, delaying the onset of Alzheimer's in early stages.Can melatonin help with heart health?
Yes, it lowers LDL cholesterol, raises HDL, and protects heart muscle from damage caused by heart attacks.Are melatonin supplements safe for long-term use?
Long-term use can reduce the body's natural production of melatonin, so supplements should be used sparingly and under medical guidance.How can I boost my melatonin levels naturally?
Get morning sunlight exposure, avoid screens before bed, and sleep in complete darkness to naturally increase melatonin production.
