Do Electronic Devices Alter Melatonin Levels

Best Melatonin For Sleep? New Melatonin Sleep Supplement Review!!

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.

What Is The Optimal Melatonin Dosage

This is a 7-minute read

When taking melatonin, it is important to take an appropriate dosage at the right time when needed for safe and effective use. It is a common misconception that taking more melatonin will result in a deeper and more restful sleep. But the reality is, too much melatonin can lead to nighttime restlessness and daytime grogginess.

What Is The Recommended Melatonin Dosage

Several studies have looked at the effective melatonin dosage for accelerating sleep onset. Some scientists are concerned that the 3mg pills commonly sold as dietary supplements might actually be detrimental. If you are thinking about taking the supplement, heres what you need to know.

The natural circadian rhythm is what causes people to sleep at night and wake up in the morning. The hormone melatonin is one of the things that make us sleepy.

If artificial lighting is dim or absent, the body begins to produce the hormone about two hours before bedtime. In most cases, this happens at around 9pm and a person is able to fall asleep around 11pm. Secretion of the hormone normally stops at around 7:30 in the morning.

In circadian rhythm sleep disorders, the clock may be different. Examples of circadian rhythm sleep disorders include delayed sleep phase syndrome and advanced sleep phase syndrome.

In delayed sleep phase syndrome, a person might not fall asleep until 2am, when most people are in their deepest phase of sleep. In advanced sleep phase syndrome, a person might fall asleep at 9pm and wake at around 4 or 5 in the morning.

The right melatonin dosage taken at the right time of the day could be beneficial for either of those conditions. The supplement is sometimes recommended for all kinds of insomnia because it has a mild hypnotic or sleep-inducing effect and is believed to be safe.

Can You Overdose On Melatonin How To Determine The Right Dosage For You

Melatonin is natural, but taking too much of the supplement may lead to adverse side effects. Heres how to recognize signs of a potential overdose.

Tossing and turning night after night can take a toll on your mental and physical health. This can make you feel sluggish, irritable, and achy throughout the day. So naturally you might seek a sleep aid for better rest.

Some people see results with over-the-counter and prescription sleeping pills. But before going down this path, consider a natural approach, like melatonin supplements.

Melatonin is a neurohormone that controls our sleep-wake cycle, and many formulations and dosages are available over the counter, explains Ofer Jacobowitz, MD, PhD, an otolaryngologist and sleep expert based in New York City. It can be useful when you are trying to advance your bedtime, especially when combined with reducing light exposure two hours before bedtime.

Melatonin is naturally produced by the pineal gland and gradually released into your bloodstream as you prepare for sleep. But if your body doesnt produce enough of this hormone, you may have problems falling asleep or staying asleep.

Melatonin supplements are generally safe when taken appropriately, but it is possible to overdo it. Read on to learn how to recognize a melatonin overdose.

Does Food Contain Melatonin

A study published in Food and Nutrition Research notes that certain food products do contain various amounts of melatonin as measured by immunological and chromatographic laboratory techniques. How consumption of these various foods might affect endogenous production sleep or was not evaluated:

  • Tomatoes
  • Wine, beer
  • Cows milk

Research finds that melatonin synthesis depends upon availability of the essential amino acid tryptophan, a needed component of the diet. If intake of tryptophan is severely restricted, synthesis of melatonin is significantly reduced in humans.

In the Nurses Health Study, no link was found between the consumption of various nutrients, such as folate, vitamin B6 and zinc and increased urinary excretion.

Diets rich in vegetables, fruits and grain products will contain considerable levels of dietary melatonin. The overall effect of dietary consumption on nighttime levels of melatonin is very limited. Melatonin production is primarily driven by the effects of light and darkness and by age, declining as we get older.

What Are The Side Effects Of Melatonin

Melatonin For Sleep Guide: How Much Melatonin To Take (Dosage) & Which Type!

Short-term use of melatonin has relatively few side effects and is well-tolerated by the majority of people who take it. The most commonly reported side effects are daytime drowsiness, headaches, and dizziness, but these are experienced by only a small percentage of people who take melatonin.

In children, the reported side effects of short-term use are similar as in adults. Some children may experience agitation or an increased risk of bedwetting when using melatonin.

For both children and adults, talking with a doctor before taking melatonin can help prevent possible allergic reactions or harmful interactions with other medications. People taking anti-epilepsy and blood thinning medications, in particular, should ask their physician about potential drug interactions.

The American Academy of Sleep Medicine recommends against melatonin use in people with dementia, and there is little research about its safety in women who are pregnant or breastfeeding.

There is also very little data about the long-term effects of melatonin supplements in children or adults. There is some concern that sustained use of melatonin could affect the onset of puberty in children, but research so far is inconclusive. Because the long-term effects are unknown, people should maintain an ongoing conversation with their doctor about using melatonin and the quality of their sleep and overall health.

Dosage: How Much Melatonin Can You Give A Dog

Heres dosage chart based on weight.

Dogs Weight
Over 100 lbs3 6 mg

Melatonin for dogs is available over the counter. However, you should always consult your veterinarian to help you determine the right dosage for your dog.

Individual dogs are given different dosages based on their difference in body size and the type of condition being managed. This means that the amount required to induce sleep in sleeping disorders may differ from the amount used to treat anxiety and fear.

Your veterinary will weigh your dog to determine his/her weight. The weight obtained will then be used to calculate the melatonin dosages for your dog with reference to the condition being managed.

Ideally, 1 mg of melatonin is the recommended dose for dogs who weigh less than 10 pounds. This is the average amount of drug that should be given to avoid complications. Dogs weighing 10 to 25 pounds are managed with a dose of 1.5mg while dogs weighing 26 to 100 pounds are managed with a dose of 3mg.

Additionally, 3 to 6 mg is recommended for dogs weighing more than 100 pounds. Some dosages may exceed these limits since these are the standard amounts for melatonin therapy in dogs.

Nevertheless, you should seek guidance from a qualified expert such as your veterinary officer to avoid the possibility of overdosing or underdosing your dog. These dosages are indicated each for a single use and should not be administered more than three times within 24 hours.

How To Tell If You Have Melatonin Deficiency

For many people, this nightly melatonin release doesn’t occur properly. Often times this is due to exposure to bright lights at night . This lack of melatonin leads to sleepless nights.

Additionally, research suggests that those who struggle with falling asleep may have a melatonin deficiency or malfunction caused by your own bodys inability to produce and/or release melatonin .

In both cases, supplementing with Melatonin is a great way to give your body what it needs to sleep at night.

If youve taken melatonin before, you know that it works well for getting you sleepy and helping your body to initially fall asleep. However, there can be some problems with this supplement depending on its quality and the quantity that you take.

Its easy to get caught up in the idea that “a natural supplement is harmless to take, so you can take however much you want if it works for you”. However, that is not the case because too much of any substance can lead to issues.

This is why low-dosage melatonin is a great alternative to the mega dosage melatonin that you often see at your local drug store.

What To Do In Case Of An Overdose

Management of melatonin overdose usually depends on how severe the condition is. The most severe manifestation of melatonin overdose is shortness of breath and difficulty in breathing.

The first thing to do in the event of an overdose is to take your dog to the veterinary officer without delay to receive prompt treatment.

If your dog is so overwhelmed that his/her breathing is failing, the veterinarian will first focus on making the dog stable before commencing any further treatment.

Once the dog is stable, it is advisable to stop the use of melatonin immediately. There are no documented effects of stopping treatment with melatonin abruptly and therefore no complication should arise due to a sudden stop in treatment

If the overdose is not severe, you only need to stop administering melatonin.

Side effects may also be caused by toxicity which have nothing to do with an overdose. In this regard, never use melatonin with artificial sweeteners in the ingredients. You will also have to take your dog to the vet for the removal of toxins and further health assessment.

What Are Signs Of A Melatonin Overdose

If you deal with insomnia, you might do anything for relief. Melatonin is a popular go-to sleep aid because its natural and has a low risk of unwanted side effects.

There dont appear to be any reports of people dying from overuse of melatonin. But while overuse might not cause death, it can cause a few of the below symptoms:

  • Headache

Theres also the threat of rebound insomnia when theres too much of the hormone in your system. Melatonin may stop working after a while, and your sleep problems could even worsen.

How Much Melatonin Should I Take For Sleep

Recommended starting doses of melatonin supplements for sleep range from around 0.5mg to about 5mg for adults, taken once daily. The maximum recommended dose is 10mg of melatonin, and taking higher doses than this may result in unwanted side effects.

That said, the proper dose depends on a few factors, including age, body weight, and sensitivity to melatonin.

The right dosage also depends on the type of severity of the sleeping disturbances you may be experiencing. Start with the lowest dose and increase each dose by 1mg if no effects are being felt at lower doses.

While melatonin may be effective to some extent for any kind of sleep disturbance, it may be especially effective for treating jet lag or certain circadian rhythm disorders.

Opting for melatonin as a short-term solution can be a great way of improving your sleep quality.

But when it comes to long-term sleeping problems your doctor may suggest re-evaluating your bedtime routines as opposed to continuing the use of melatonin as a long-term solution.

Always consult your doctor before trying new vitamins or supplements.

Studies On Melatonin Dosage

When Should You Take Melatonin

When it comes to when you should actually take melatonin supplements, many people assume that it is appropriate to take them right before bedtime. But this may not actually be the most ideal scenario.

Timing is key in terms of the effectiveness of your melatonin supplements, and taking them too close to your desired time of sleep may leave you disappointed. Instead of taking your supplements right when you are hoping to fall asleep, the right time may actually vary depending on your preferred sleeping schedule.

Someone who tends to go to sleep after midnight but who wants to be asleep by around 11 p.m. may be best satisfied by taking melatonin at 6 p.m., and someone who goes to bed around 8 p.m. but rises early, at around 4a.m., may want to take their melatonin in the afternoon.

The reason why you may want to take your melatonin a few hours before you head to bed is because melatonin actually takes a little while to start working in your body.

What Are The Appropriate Doses Of Melatonin In Elderly People

Melatonin does not have a standard dosage that fits all. But when it comes to older people, the best results showed dosages from 2 to 3 mg taken 30 minutes before bedtime. These quantities do not cause overdose symptoms or side effects, significantly improve the quality of sleep, and help maintain alertness during the next day, according to Happysleepyhead.com.

Doctors usually recommend starting with the smallest dosage and gradually increasing it. Thus, you can better understand how much melatonin has the most pronounced effect.

Quick note: A large dose does not necessarily mean falling asleep faster. In many cases, smaller doses will be digested quicker .
