Melatonin, often called the "sleep hormone," is a natural substance that helps control sleep and other important functions in the body. It plays a key role in our daily rhythms, affecting when we feel sleepy, our mood, and even some seasonal behaviors.
Dr. Russell Reiter is a well-known expert in melatonin research. He has spent many years studying this important hormone and has made many important discoveries. Dr. Reiter's work provides deep insights into how melatonin helps keep us healthy.
This article is based on an interview with Dr. Reiter on the YouTube channel "Chris Beat Cancer," titled "Dr. Russell Reiter on the Miraculous Benefits of Melatonin." Everything in this article comes from that interview.
We will cover what melatonin is, its health benefits, how much to take, and its role in treating various conditions. Whether you want to know how melatonin works, its benefits, or its role in health, this article will help you understand melatonin through Dr. Reiter's expert views.
"Melatonin is a very interesting and multifunctional molecule. It is very old, existing in every species currently living or ever existed."
Melatonin is a hormone made by the pineal gland in the brain. Often called the "sleep hormone," it helps control when you fall asleep and wake up. Dr. Aaron Lerner discovered melatonin in 1958, and it has been studied extensively since then.
Melatonin does many important things in the body:
Your body has natural processes called circadian rhythms, which follow a 24-hour cycle and are influenced by light and darkness. Melatonin is crucial in regulating these rhythms.
Dr. Russell Reiter is a highly respected professor of cell biology, known for his extensive research on melatonin. He holds four honorary MD degrees and one honorary Doctor of Science degree.
Over his long career, Dr. Reiter's work has been widely cited in medical and scientific literature, making him one of the leading experts in the field of melatonin research
Dr. Reiter's interest in melatonin began somewhat unexpectedly. Melatonin was discovered in 1958 by Dr. Aaron Lerner, and initially, Dr. Reiter did not see it as an interesting topic. However, his perspective changed during his time in the military.
In the early 1960s, there was a focus on long-distance space travel, and researchers were exploring ways to help astronauts hibernate during long missions.
Dr. Reiter was part of a team tasked with isolating a substance that could induce hibernation. This research led him to melatonin, which was found to play a role in regulating hibernation, although it is not the hibernating factor itself. This experience sparked his lifelong interest in studying melatonin.
Melatonin was first discovered in 1958 by Dr. Aaron Lerner, a dermatologist who identified it while researching the pineal gland. Early research revealed that melatonin is produced in the pineal gland, a small endocrine gland located in the brain.
The production of melatonin is directly influenced by the presence of light; it is produced in larger quantities during the night and reduced during the day.
Dr. Russell Reiter's research further elucidated that melatonin production is part of a daily cycle, aligning with the natural light-dark cycle of the environment. This cyclic production helps regulate various bodily functions, particularly those related to sleep.
Melatonin plays a crucial role in regulating circadian rhythms—the natural, internal processes that follow a 24-hour cycle.
These rhythms are essential for maintaining consistent sleep-wake cycles, hormone release, body temperature, and other vital functions.
Although humans are less influenced by seasonal changes compared to other animals, the seasonal role of melatonin underscores its importance in adapting to environmental changes.
The discovery of melatonin in 1958 marked the beginning of a new era in understanding the pineal gland and its functions. Initial studies focused on its production and role in regulating sleep.
Over time, researchers like Dr. Russell Reiter expanded the scope of melatonin research, uncovering its antioxidant properties and potential health benefits.
Melatonin plays a vital role in regulating sleep by controlling the body's circadian rhythms. These rhythms are essentially the body's internal clock, which governs the sleep-wake cycle over a 24-hour period. The production of melatonin increases as darkness falls, signaling to the body that it is time to prepare for sleep.
Dr. Reiter explains the concept of the "sleep gate," which is a window of time during the evening when the body is most ready to fall asleep. Melatonin helps to open this sleep gate, making it easier to transition from wakefulness to sleep. Here's how it works:
Understanding and utilizing the sleep gate can help improve sleep quality and ensure that you fall asleep more easily.
While melatonin is widely used to help with sleep, its effectiveness can vary significantly from person to person. Several factors contribute to this variability:
Artificial light, particularly blue light from screens and LED lights, can significantly disrupt melatonin production. Here's how:
Natural light patterns play a crucial role in regulating melatonin production and maintaining healthy circadian rhythms:
To enhance melatonin production and improve sleep quality, consider these practical tips:
Melatonin is a powerful antioxidant that helps protect cells from damage caused by free radicals. These molecules can harm cells and contribute to aging and diseases like cancer. By neutralizing free radicals, melatonin helps maintain cellular health and prevent oxidative stress.
Research shows that melatonin has significant anti-cancer properties:
Melatonin also plays a critical role in supporting the immune system:
As people age, their natural production of melatonin decreases. This decline can lead to disruptions in sleep patterns, reduced sleep quality, and increased susceptibility to various health issues.
Melatonin supplementation may help delay the onset of age-related diseases:
Dr. Russell Reiter has been taking melatonin for 28 years and believes it has significantly contributed to his overall health and longevity.
He suggests that melatonin supplementation can help maintain good health as people age, supporting sleep and immune function and protecting against age-related diseases.
Dr. Reiter's personal experience underscores the potential benefits of long-term melatonin use for aging individuals.
For adults, typical melatonin doses range from 1 to 5 mg, taken about 30 to 60 minutes before bedtime to help with sleep. For other health conditions, higher doses may be recommended based on individual needs and under medical supervision.
Dr. Reiter has been taking melatonin for many years, and his current regimen is higher than typical doses due to his focus on its antiviral and general health benefits. He currently takes about 100 mg nightly, especially to support his immune system against COVID-19.
As melatonin levels naturally decline with age, older adults might benefit from higher doses to maintain good sleep and overall health. It's important to adjust the dosage based on individual health status and consult with a healthcare provider.
Recent studies have explored melatonin's potential in treating COVID-19 due to its antiviral properties and ability to support the immune system. Research indicates that melatonin might reduce the severity of infections, shorten hospital stays, and decrease mortality rates.
Melatonin can help manage severe illnesses by boosting immune responses, reducing inflammation, and protecting cells from oxidative stress. This makes it beneficial for conditions like sepsis, heart attacks, and strokes.
Ischemia-reperfusion injury occurs when blood supply returns to tissue after a period of ischemia or lack of oxygen, causing significant damage. Melatonin's antioxidant properties can help mitigate this damage, improving outcomes in heart attacks and strokes.
Blue blocker glasses can help reduce the impact of artificial blue light on melatonin production. They are particularly useful in the evening to minimize melatonin suppression and support better sleep.
To enhance melatonin production:
Dr. Reiter supports the use of blue blocker glasses but notes that they should be wraparound style for maximum effectiveness. He also emphasizes the importance of overall good sleep hygiene and reducing light exposure at night.
Recent studies suggest that infrared light can stimulate melatonin production in cells. This emerging field of research highlights the potential benefits of infrared light for enhancing melatonin levels.
Infrared saunas and other devices may help increase melatonin production, offering benefits for sleep, antioxidant protection, and overall health.
Infrared light penetrates deep into the body, stimulating melatonin production directly within cells. This can enhance melatonin's protective effects throughout the body.
Research shows that melatonin can reduce damage from ischemia-reperfusion injury, which occurs during heart attacks and strokes, by neutralizing harmful free radicals.
Melatonin can support reproductive health in aging women by protecting eggs from oxidative damage and potentially delaying menopause-related changes.
Continued research on melatonin aims to uncover more of its benefits, including its potential in treating various diseases, supporting mental health, and enhancing overall well-being.
Melatonin is generally safe with minimal side effects, such as mild dizziness or sleepiness. Most people tolerate it well.
There are rare reports of adverse effects, such as severe diarrhea or gynecomastia (breast development in men). However, these instances are extremely uncommon.
Compared to medications like aspirin, which can cause serious side effects, melatonin is much safer. Aspirin toxicity can lead to gastric ulcers and even death, while melatonin has no known lethal dose.
The optimal dose of melatonin for cancer patients can vary based on the type of cancer, patient age, and overall health. Doses as high as 120-150 mg per day have been suggested in some studies.
While research is ongoing, current evidence supports the use of higher doses of melatonin for cancer patients under medical supervision to potentially inhibit tumor growth and enhance the effectiveness of other treatments.
Melatonin's antioxidant and immune-boosting properties make it a valuable adjunct in cancer treatment and prevention, potentially reducing the risk of metastasis and improving patient outcomes.
Dr. Reiter emphasizes melatonin's wide-ranging benefits and its potential to improve health and prevent diseases. He advocates for its broader use and further research to fully understand its capabilities.
