How Does Melatonin Affect The Brain And The Body
Melatonin turns certain areas of the brain on and off, says Alon Y. Avidan MD, MPH, director of the UCLA Sleep Disorders Center, and Professor at the UCLA Department of Neurology in Los Angeles, California. Melatonin helps with the timing of sleep to allow people to have a more regular circadian phase and it may help to strengthen the immune system, too. Its important to improve sleep and the timing of sleep so people can have an optimal immune response, he says.
It Can Lower Your Energy Levels And Mood
Dealing with pre-existing mental health conditions on a daily basis is challenging enough as it is. Unfortunately, Adimoolam explains, “Individuals with known mood disorders like depression may experience worsening depressed mood and/or anxiety.” Melatonin can lower one’s mood and energy levelsin the process of relaxing and preparing the body for sleepwhich can mimic or foster a depressive state in people who already suffer from the illness.
Although, some experts have reported that you can attempt to counteract the negative toll melatonin takes on mental health by increasing your vitamin D intake. Since vitamin D is a natural way to improve one’s mood, it may help some. But many who still experience excessive mood changes must stop taking the supplement altogether and discuss uneasy sleep patterns with a doctor.
Is It Worth The Risks
Melatonin is a powerful hormone, and works unlike other sleeping aids. Its a sleep regulator, rather than a sleep initiator. Those who are really struggling with insomnia may feel compelled to take a high dose, thinking itll have a stronger effect. However, at the wrong dose, melatonin can actually make the sleeping cycle much worse, inducing drowsiness and preventing the body self-regulating its natural sleep cycle.
Melatonin dosage comes in a wide variety of strengths, from 0.2 mg to 20.0 mg. The most commonly useful dosage falls between 0.3 and 1.0 mg. Typically, if you can find the dosage perfect for you, you can get all the benefits of melatonin whilst still minimizing the side effects. Just because its unregulated and easy to purchase doesnt mean it can be taken without consequence. Exercising caution when taking melatonin is the best way to get maximum benefits with minimum drawbacks.

How To Use Melatonin For Jet Lag
Jet lag is an air travel problem that causes difficulty in sleeping, fatigue, trouble concentrating, constipation, and other symptoms. Jet lag is much more likely if you cross over several time zones, and can worsen the more time zones you cross.
Effective starting doses for jet lag range from 0.3 to 0.5 mg. Smaller doses may work for some while others may need a higher dose. It may be more difficult to fly east, when time is lost, rather than to fly west, when you gain it back. High doses, such as 20 mg pills are available for purchase on the Internet, but such high doses are not normally recommended or needed, and may greatly increase side effects.
- Eastbound: If you are traveling east, say from the US to Europe, take supplemental melatonin for sleep after dark, 30 minutes before bedtime in the new time zone or if you are on the plane. Then take it for the next 4 nights in the new time zone, after dark, 30 minutes before bedtime. If you are still feeling drowsy the day after using this medication, try a lower dose.
- Westbound: If you are heading west, for example, from the US to Australia, a dose is not needed for your first travel night, but you then may take it for the next 4 nights in the new time zone, after dark, 30 minutes before bedtime. Melatonin may not always be needed for westbound travel.
Given enough time , jet lag will usually resolve on its own, but this is not always optimal when traveling.

Melatonin: What Is It Side Effects And Benefits
Melatonin, also known as the sleep hormone, is produced in our brain, specifically in the pineal gland. Although this gland performs various functions in our body, its main function is to regulate the sleep-wake cycle, which it does by transforming serotonin into melatonin. Melatonin is synthesised from an amino acid known as tryptophan

Can You Naturally Raise Your Melatonin Levels
Melatonin is a natural hormone and there are ways to measure levels in the body, says Dr. Kolla, but this is usually done in research settings. There really is nothing we can do to increase our levels. Light can suppress its secretion, so avoiding light, especially bright light, in the evenings is helpful.
Being conscious of the screens youre staring at in the evening can play a huge role in when your melatonin levels change, but this doesnt raise the percentage of the hormone in your body.
Taking supplements orally can increase the levels of melatonin in the blood to much higher levels than the body naturally produces. So exercise caution before ingesting high dosages as it can lead to spill-over effects and disrupt sleep further.
Is Melatonin Safe For People With Mental Illness
Taking melatonin can help those with depression because it improves seasonal affective disorder, says Dr. Avidan. When people are not getting enough light exposure , like in Washington state or the Midwest, they tend to get more severe depression, he says. Using artificial light during the day can help the timing and release of melatonin, which will have a positive effect on mood.
People with major depression or psychotic disorders should consult with their doctor before taking melatonin since mood changes, hallucinations, and paranoia have been reported. If youre dealing with anxiety or depressionlike many of us this past yearor if you have , melatonin may be able to help but only your doctor can tell you for sure.

Can You Develop A Melatonin Dependency
Melatonin does not cause physical dependency. However, it is not meant to be used long term. Talk with your healthcare provider about other options if you have been using melatonin for one to two months.
Melatonin is not safe for people with an autoimmune disorder, a seizure disorder, or depression. It is also not considered safe for people who are pregnant or breastfeeding.
Is Melatonin Safe Common And Uncommon Side Effects
For those struggling with their sleep cycles, taking oral melatonin is one of the first ports of call. But in spite of its common usage and over the counter status, there are still a few question marks surrounding it. Taking melatonin, as with anything else, as a supplement comes with potential for side effects. Some of these are well-known and publicized, but other, rarer side effects are more obscure and unknown to the general public. So is the taking of melatonin to aid sleep safe?

Who Should Avoid Melatonin
There are several groups that should consider avoiding melatonin.
- People taking interfering medications
- Young children who simply have a hard time sleeping.
- People with chronic insomnia. Insomnia is a much bigger issue than simple melatonin supplementation can solve. If you suffer from this – please see a doctor.
- People with restless leg syndrome. Melatonin can sometimes interfere or make this worse.
- People with dementia. Because dementia can cause people to metabolize the hormone more slowly – they may become drowsy during the daytime and pose a danger to themselves.
What Are Melatonin Supplements
Oral forms of synthetic melatonin include melatonin gummies, pills, liquids, chewables, and capsules. You can purchase the hormone in other forms, too, including melatonin sprays, powder, patches, and creams, all of which are available in grocery stores, pharmacies, and health food stores. Melatonin supplements are marketed to help with sleep and jet lag.
As pointed out by the JAMA study, many melatonin users regularly take doses higher than the maximum recommended 5 milligrams per night. This is particularly concerning in regard to children. A report published in June 2022 by the Centers for Disease Control and Prevention examined data between the years 2012 and 2021 and found that poison control had fielded 260,435 calls about kids who had taken too much melatonin. Of those, two children under the age of 2 died, five were put on a ventilator, nearly 300 ended up in intensive care, and more than 4,000 were hospitalized.
Part of the problem may be that there is no general consensus regarding melatonin dosage, according to the aforementioned book. Recommended dosages vary by brand, and can range from 0.3 to 10 mg, per the The Sleep Doctor. Low doses may be used for circadian rhythm synchronization, while sleep disorders may require doses ranging from 0.6 to 5 mg.
Its important to speak to a qualified healthcare provider about the correct dosage for yourself, or for a child who has sleep issues because of a developmental or neurological problem.

Is It A Hormone
Melatonin is a hormone. The pineal gland in the brain releases it in cycles. Production increases at night when the light outside starts to fade.
Melatonin acts as a chemical messenger. It tells other organs and tissues how to function. Melatonin signals to the body that it is time to go to sleep.
Melatonin is known as the sleep hormone. People with low melatonin levels may not sleep as well as those who have higher levels.
Do Electronic Devices Alter Melatonin Levels
Light at night blocks the production of melatonin, and this has been shown to cause sleep disturbances in people who use electronics that emit light at night. Researchers have found that light from electronic devices can block the release of natural hormone melatonin at night. The effect was most significant for younger children, with nighttime levels reduced by up to 37 percent in certain cases. This can also be problematic for children between ages 9 and 16.
Studies show that light after dark lowers melatonin levels which may lead to difficulty in initiating sleep. Electronic light-emitting devices such as the television, laptops, smartphones and tablets often find their way into the bedroom at night, or are used after dark. Children should not have electronics, including TVs, in their bedroom at bedtime and everyone should avoid use of light-emitting devices and screen time at least one hour before bedtime.
