Fall Asleep Faster and Sleep Better With This!

An estimated 40 percent of Americans are sleep deprived, according to the documentary “Sleepless in America,” with many getting less than five hours of sleep per night.

There are many reasons for this, from intentionally staying up late to watch TV or surf the web to health problems (like pain) that keep you awake.

Millions of Americans struggle to fall asleep each night, including about 10 percent who suffer from chronic insomnia. This latter condition involves difficulty falling asleep and staying asleep, as well as waking up too early in the morning.

In many cases, making changes to your sleep-hygiene routine and lifestyle, such as exercising more and avoiding exposure to blue light at night, can significantly improve your sleep.

However, if you feel like you’ve tried virtually everything and you’re still struggling to get a restful night’s sleep, it might be time to consider two natural supplements, melatonin and 5-hydroxytryptophan (5-HTP).

Why Melatonin Is Important for Sound Sleep

Your brain typically starts secreting the hormone melatonin around 9 or 10 p.m., which makes you sleepy. These regularly occurring secretions help regulate your sleep cycle as well as provide other important health benefits, including helping to prevent cancer.

Melatonin acts as a marker of your circadian phase or biological timing. In a nutshell, this hormone influences what time of day or night your body thinks it is, regardless of what time the clock on the wall displays.

Melatonin is produced by a pea-sized gland in the middle of your brain called the pineal gland.

In a normal night’s sleep, your melatonin levels stay elevated for about 12 hours. Then, as the sun rises, your pineal gland reduces your production of melatonin, and the levels in your blood decrease until they’re hardly measurable at all.

When your circadian rhythms are disrupted, such as from shift work, jet lag or nighttime light exposure, your body produces less melatonin.

Melatonin deficiency may come with some profound biological disadvantages, such as higher levels of inflammation, a weakened immune system, and an increased risk of cancer.

Who May Benefit From Melatonin Supplements?

It is best to encourage your body to produce its own melatonin. Your pineal gland produces melatonin roughly in approximation to the contrast of bright sun exposure in the day and complete darkness at night.

If you are in darkness all day long, it can’t appreciate the difference and will not optimize your melatonin production.

So one of the best ways to increase your melatonin production naturally is to get exposure to bright sunlight during the day and sleep in complete blackness at night. Supplementation may be beneficial in some cases, particularly if your circadian rhythm is off (such as from jet lag).

In a Cochrane review that analyzed 10 randomized trials, melatonin significantly reduced or prevented jet lag when taken close to the target bedtime at the destination.

The researchers recommended melatonin for adult travelers flying across five or more time zones, particularly in the eastern direction, and, if necessary, for those flying across two to four time zones.1

A recent review published in the French journal Annales Pharmaceutiques Françaises further revealed the importance of melatonin in regulating the body’s internal clock for optimal sleep:2

“The internal or biological clock which is located in the suprachiasmatic nuclei of the anterior hypothalamus is controlled by clock genes and environmental factors which are able to synchronize the clock to 24h.

Rhythm desynchronization (shiftwork and nightwork, transmeridian flights, aging, some psychiatric diseases, blindness, intake of some drugs … ) occurs when the internal clock does no longer work in harmony with the astronomical time i.e. our watch.

The circadian system consists of three major elements, which are the clock, the retinohypothalamic tract and melatonin which is secreted by the pineal gland and considered as the arrow of the clock.

Both light and melatonin present a phase response curve useful for the treatment of sleep circadian disorders.”

More Is Not Typically Better With Melatonin Supplementation

As for dosage, the researchers noted, “Daily doses of melatonin between 0.5 and 5 mg [milligrams] are similarly effective, except that people fall asleep faster and sleep better after 5 mg than 0.5 mg. Doses above 5 mg appear to be no more effective.”

In a study looking into the use of melatonin for primary sleep disorders, the supplement also appeared safe and effective, working to decrease the time it takes to fall asleep and improve total sleep time and quality.3

Keep in mind that only a very small dose is required — typically 0.25 mg or 0.5 mg to start with, and you can adjust it up from there.

Taking higher doses, such as 3 mg, can sometimes make you more wakeful instead of sleepier, so adjust your dose carefully and, ideally, under the guidance of a holistic health care practitioner.

In addition, melatonin supplementation may be most effective in people with low melatonin levels. If your levels are optimized, you may not experience additional sleep benefits from added supplementation.

Melatonin’s Link to Diabetes Risk

About one-third of people are thought to carry a gene variant to melatonin receptor 1B (MTNR1B), which increases the risk of developing type 2 diabetes.

A new study from researchers at Lund University in Sweden has now revealed that the effect of melatonin is stronger in carriers of this genetic variant, and this may be responsible for the increased diabetes risk.4

The study involved 23 carriers of the genetic variant and 22 non-carriers. Both groups received 4 mg of melatonin at bedtime for three months. The variant carriers had lowered insulin secretion and significantly higher blood sugar levels after melatonin supplementation.

Similar results were first demonstrated in lab-cultured beta cells and mice, which showed melatonin causes insulin-producing cells to reduce insulin release via signaling from MTNR1B melatonin receptor proteins.

Mice with disrupted MTNR1B receptors produced more insulin, but in people with the aforementioned genetic variant, the amount of MTNR1B protein on insulin-producing cells is increased.

Since the cells then become more sensitive to melatonin, they produce less insulin, leading to higher blood sugar levels. As reported by Medical News Today:5

“Senior investigator Dr. Hindrik Mulder, a professor specializing in molecular metabolism at Lund’s Diabetes Center, says their findings could explain why the risk of developing type 2 diabetes is higher in people who work overnight or who have sleeping disorders.”

What Is 5-HTP and How Does It Affect Sleep?

Your body produces 5-HTP (5-hydroxytryptophan) from the amino acid tryptophan (found in foods like poultry, eggs and cheese).

However, eating tryptophan-rich foods is not likely to significantly increase your 5-HTP levels, so 5-HTP supplements (which are made from extracts of the seeds of the African tree Griffonia simplicifolia) are sometimes used.

The chemical 5-HTP works in your brain and central nervous system by promoting the production of the neurotransmitter serotonin, and thereby may help boost mood and enhance sleep.

In one study, an amino acid preparation containing both GABA (a calming neurotransmitter) and 5-HTP reduced time to fall asleep, increased the duration of sleep and improved sleep quality.6 Further, as noted by the University of Maryland Medical Center:7

“In one study, people who took 5-HTP went to sleep quicker and slept more deeply than those who took a placebo. Researchers recommend 200 to 400 mg at night to stimulate serotonin, but it may take six to 12 weeks to be fully effective.”

There may be some beneficial “side effects” to 5-HTP as well. Research suggests the supplement naturally reduces appetite and food intake (including reduced carbohydrate consumption) and is associated with significant weight loss.8

Another study found 5-HTP led to significant improvements in symptoms of fibromyalgia as well, with only mild and transient side effects reported.9 The anti-depressant properties of 5-HTP are also of interest, and preliminary research suggests it may work as well as certain antidepressants in people with mild to moderate depression.10

Try Natural Sleep Aids Before Sleeping Pills

Natural sleep aids work with your body’s natural circadian rhythm to help you get truly restful sleep. This is not the case with prescription sleeping pills. A study in 2012 revealed that people who take sleeping pills are not only at higher risk (by 35 percent) for certain cancers, but they are also nearly four times as likely to die as people who don’t take them. The list of health risks from sleeping pills includes:

  • Higher risk of death, including from accidents
  • Increased risk of cancer
  • Increased insulin resistance, food cravings, weight gain and diabetes
  • Complete amnesia, even from events that occurred during the day
  • Depression, confusion, disorientation, and hallucinations

Research involving data from more than 10,500 people who received drugs for poor sleep (including benzodiazepines) also showed that “as predicted, patients prescribed any hypnotic had substantially elevated hazards of dying compared to those prescribed no hypnotics.”

The association held true even when patients with poor health were taken into account — and even if the patients took fewer than 18 pills in a year.11 In “The Dark Side of Sleeping Pills,” an e-book by one of the study’s researchers, Dr. Daniel Kripke, it’s explained:12

“The patients who took sleeping pills died 4.6 times as often during follow-ups averaging 2.5 years. Patients who took higher doses (averaging over 132 pills per year) died 5.3 times as often. It seems quite likely that the sleeping pills were causing early death for many of the patients …

Theoretically, there could be confounding factors or biases in the selection of patients which caused these deaths without involving sleeping pills. We can only say that we found almost no evidence of such biases … If sleeping pills cause even a small portion of the excess deaths and cancers associated with their use, they are too dangerous to use.”
