Melatonin, Sleep And Cancer


Deep, restful sleep is essential for healthy immune function. It’s a foundational pillar of health, and is just as important as getting adequate nutrition, and exercising consistently. Sleep is absolutely vital for hormonal balance, keeping inflammation in check, and reducing stress levels. Melatonin is the hormone responsible for sound sleep. Not only does it help you fall asleep, it helps you stay asleep throughout the night. Let’s talk more about melatonin, sleep, and cancer.

What Is Melatonin?


Melatonin is a hormone produced from the amino acid tryptophan. The pineal gland produces minute amounts of melatonin in the absence of light with levels peaking during sleep. Tissues in the central nervous system have receptors for melatonin, but it’s in the gastrointestinal tract that the majority of melatonin is made.

Interestingly, there is an elevation in melatonin after eating, which is one reason you may feel tired after a meal. Once melatonin is produced, it only stays in the bloodstream for up to 90 minutes. People with advanced cancer have been found to have lower levels of melatonin.

This sleep-regulating hormone dictates circadian rhythms, has neurotransmitter modulatory activity, and opposes cortisol. When levels of cortisol are high in the morning, melatonin is low. The converse is also true, as the day progresses, and cortisol levels wane, melatonin production increases. All of this happens if everything is functioning as it should.

If the body is in a stress response, however, cortisol levels can be all over the place. Instead of being high in the morning to get you out of bed, they may be low, and rather than being low at night to help you wind down and promote rest, they’re often high. This is an unfortunate scenario, resulting in more and more dysfunction if the imbalance continues.

How Does Inadequate Sleep Affect Health


In order to sleep soundly at night you need healthy levels of melatonin. The importance of sleep is often not given its rightful due, in fact, getting by on little sleep can even be a badge of honor. In reality, if you don’t sleep well, you’re compromising your health because of the toll it takes on the immune, endocrine, gastrointestinal, and central nervous systems.

Exercise, optimal nutrition, detoxification, and supplementation are all foundational pillars of health, but they’ll never be able to replace or make up for sleep deprivation. Sleep keeps the immune system in tip top shape, while dampening the stress response. When you’re chronically sleep deprived, your body perceives this as a stress, which negatively impacts cortisol levels.

High cortisol leads to all sorts of dysfunction in the body, including a breakdown of the mucosal lining in the small intestine, which houses 80% of the immune system. An unhealthy gut leads to compromised immunity, inflammation, and hormonal imbalances, which are a set up for poor sleep.

Poor Sleep And Inflammation


Imbalances in cortisol and melatonin can result in a vicious cycle of sleep deprivation, cytokine production and inflammation, gut degradation, and poor immunity, all of which inhibit quality sleep, and the cycle repeats itself. If poor sleep promotes inflammation, then inadequate sleep is a precursor to chronic disease and pain syndromes, which are characterized by inflammation.

The inflammation I’m referring to is chronic inflammation. Acute inflammation is a protective response that is necessary and short lived. It’s when inflammation is chronic that it becomes problematic.

Benefits Of Melatonin


Melatonin has benefits far beyond being a powerful sleep aid and jet lag preventative. It’s also an antioxidant so if you’re not making enough of it, you won’t be able to fight oxidative stress and free-radical damage.

Low melatonin is implicated in disease states because of its adverse effect on immune function, which is significant because a strong immune system is what will ultimately prevent cancer and chronic disease. Since the vast majority of melatonin is made in the GI tract, if gastrointestinal health is sub par, melatonin levels will be low.

Melatonin:

  • Reduces the frequency and duration of migraines
  • Decreases oxidative stress and free-radical damage
  • Reduces inflammation and chronic disease
  • Prevents or alleviates tinnitus
  • Dampens the stress response
  • Lowers cholesterol levels and promotes cardiovascular health
  • Protects the esophagus from excess acid
  • Prevents insulin resistance and type II diabetes by regulating insulin
  • Promotes eye health
  • Prevents certain types of cancer, including breast and prostate cancer

Why The Sleep Hormone Is A Viable Cancer Treatment


High-dose melatonin is used as an adjunct cancer treatment because of its effect on the regulatory processes in the body. It’s also used to slow the progression of autoimmune diseases, and is gaining attention in its ability to extend life span, and treat age-related diseases. It’s also a potent antioxidant.

Melatonin inhibits the growth of cancer by producing Interleukin-1 and Interleukin-2. The former prevents microbial infections, and the latter regulates T and B cells. Interleukin-2 also governs natural killer cells, which are responsible for killing cells that could potentially turn cancerous. Low levels of melatonin are implicated in cancer risk.

Using high doses of melatonin to treat cancer is not widely known as it’s not in the pharmaceutical companies’ best interest to promote an efficacious, yet inexpensive treatment. In addition to its favorable effect on immune function, melatonin also protects against the negative side effects of chemotherapy and radiation, and accelerates wound healing following surgery.

Ongoing clinical trials have been conducted showing how melatonin can be used to manage symptoms associated with cancer and its treatment, while decreasing mortality rates.

Melatonin And Apoptosis


Because melatonin is both water and fat soluble, it can easily penetrate cell membranes, and is a mild chelator, and free-radical scavenger, decreasing oxidative damage to proteins and DNA. Melatonin directly eradicates various types of tumor cells by inducing apoptosis, or programmed cell death, while inhibiting tumor and cancer cell growth.

One mechanism by which melatonin inhibits cancer growth is by lowering body temperature. It also inhibits   angiogenesis or the development of new blood vessels, which in turns prevents metastasis. Melatonin slows cancer progression by activating the cytokine system, and stimulating macrophage and monocyte activity.

Many cancer patients don’t die of the disease itself, but rather from poorly managed symptoms, such as weight loss, loss of appetite, and muscle wasting. Melatonin prevents cachexia and anemia, promotes the production of platelets, stimulates appetite, and alleviates the exhaustion and depression commonly experienced by those with cancer. And because it’s a natural analgesic, it relieves pain.

Dosages Used For Cancer


Melatonin levels have been shown to be lower in cancer patients, whereas, levels normalize when the cancer goes into remission. Certain subsets of the population are at increased risk of having low levels of melatonin, including shift workers, insomniacs, pilots, flight attendants, those exposed to high levels of EMFs, people with ulcerative colitis, quadriplegics, spinal cord injury patients, and people taking medications for high blood pressure, which lower serum levels of melatonin.

20-100 milligrams of melatonin per day are used to treat cancer, and slow the progression of autoimmune diseases. It can be taken orally by mouth or as a lozenge that is dissolved underneath the tongue. Melatonin is injected into muscles as a cancer treatment or applied topically to prevent and soothe mouth ulcers caused from chemotherapy and radiation.

Side Effects


Toxicity associated with melatonin is extremely low even when high doses in the 3 to 6 gram range are used. Side effects are typically minimal, but may include headaches, nausea, or abdominal pain. Supplementing with melatonin is safe, and is certainly much safer than taking prescription medications for sleep.

Since melatonin decreases with age, supplementing with it may be beneficial for those with age-related diseases, such as Alzheimer’s disease. Elderly men have lower levels of melatonin than do women, which may be one reason women live longer than men. Meditation boosts melatonin and may be why it’s so effective.

Here’s a reputable brand of high-dose melatonin.

Key Points


Melatonin not only promotes deep sleep, it’s also essential for an optimally functioning immune system, which is the best defense against cancer. It induces apoptosis, inhibits angiogenesis, stimulates monocyte and macrophage activity, scavenges free radicals, and mitigates the side effects of chemotherapy and radiation.

Melatonin is safe, affordable, and effective. Please learn more about using melatonin as an adjuvant cancer treatment if you or someone you love has cancer.

  1. This was an extremely useful post for me, as I have stage 2 cancer (skin) and am treating it now using natural treatment as opposed to other types of treatments that typically are prescribed by doctors. So far it appears that the regimen is effective, and I feel better than many do when they undergo chemotherapy or radiation therapy.

    The melatonin angle is new information for me, and the ways it can help are many and varied per your information. Not only does it help with sleep and all the benefits that brings to bear, but cancer as well. That alone is enough for me to add the 3-6 gram range you mention.

    Thanks for opening my eyes to a whole new avenue of intervention through adding supplements of melatonin to my regimen. I will be taking action, as I plan on being around a while longer yet!

    • Thank you Dave. I’m sorry to hear you have cancer, but am glad you are using natural treatments. Please learn more about melatonin and cancer. I’m happy you’re willing to try it. Best to you!
