Using Melatonin For Sleep
Researchers have tested melatonin on people with insomnia. They have also looked at whether melatonin helps shift workers, military personnel, older adults, and kids.
Most studies have just looked at short-term melatonin use, ranging between a few days to just over three months.
Research has shown that melatonin may have these benefits:
- Fall asleep faster: People who took melatonin fell asleep between 22 and 34 minutes sooner than people who took placebo pills.
- Improve sleep efficiency: Sleep efficiency refers to the time you spend sleeping compared to the time you were in bed. Some studies have shown that taking melatonin might make your sleep efficiency better.
- Help children fall asleep and stay asleep longer. Melatonin may help kids with sleep problems, such as those that are common in autism spectrum disorder and attention deficit hyperactivity disorder .
- Reset your sleep-wake cycle: When you feel like going to sleep and waking up is controlled by your circadian rhythm. Some studies have shown that melatonin may help regulate this cycle.
Additional Steps To Improve Sleep
People with sleep problems can benefit from taking steps to develop healthy sleep habits. Even if melatonin offers relief, improving your sleep routines and environment can promote better sleep quality.
- Optimize your sleep hygiene: Sleep hygiene refers to behaviors that affect sleep quality for better or worse. Guidelines for healthy sleep hygiene include going to bed and waking up at the same times each day, abstaining from caffeine and alcohol in the hours leading up to bed, and maintaining a quiet, relaxing bedroom environment that is conducive to relaxation. It may also help to invest in a better mattress and new bedding.
- Limit your screen time in the evening: Cellphones, tablets, televisions, and computers all feature screens that emit blue light, which can interfere with the circadian rhythm that guides your sleep cycle. Studies have shown that reducing your exposure to screened devices can help you fall asleep more easily.
- Schedule quick afternoon naps: Napping is an effective way for sleep-deprived people to catch up on their daily sleep allotment. However, long naps can make it more difficult for you to fall asleep at your normal bedtime. Naps that last between 10 to 20 minutes are considered ideal because they are long enough to help you feel refreshed afterward without allowing you to enter the deep sleep stages of your sleep cycle.
Should Certain People Avoid It
Consult a physician prior to use if taking other drugs such as anticoagulants, anticonvulsants, blood pressure medications, immunosuppressive medications, or sedative, hypnotic or psychotropic medications. If you have an autoimmune disorder, liver or chronic kidney disease, asthma, cardiovascular disease, depression, diabetes or hypoglycaemia, hormonal disorder, migraines, or seizure disorders, you should consult your physician. For use beyond 4 weeks, or if symptoms persist for more than 4 weeks , consult your physician.

When Melatonin Can And Can’t Help
Some people with certain kinds of sleep disorders may get some relief from melatonin, research suggests, but theres less evidence for its use with more common forms of insomnia, according to the NIHs National Center for Complementary and Integrative Health.
A 2013 meta-analysis found that on average, people with insomnia fell asleep about 7 minutes faster with melatonin than with a placebo. While most melatonin side effects are mild, CRs survey showed that people may be taking it in unsafe ways, for example, driving too soon after taking it or taking it long term when theres little data indicating that longer than three months is safe.
Because of the lack of evidence, the American Academy of Sleep Medicine recommends clinicians not use melatonin as a treatment for insomnia.
But that doesnt mean it cant help anyone.
About 5 to 10 percent of people may feel sleepy after taking melatonin, says Alcibiades Rodriguez, MD, the medical director of the Comprehensive Epilepsy Center-Sleep Center at New York University.
Usually the people that get more benefit are the elderly, maybe 70 or older, and young patients, he says. Thats because older patients and young children are less likely to produce sufficient melatonin on their own, though its important to consult a medical professional before giving a child melatonin. Theres still little research on melatonin in kids and some concern about how it might affect development, especially around puberty.
Is Melatonin Useful For The Treatment Of Insomnia

People with insomnia can have trouble falling asleep, so it might seem logical that melatonin could help with this aspect. We looked at published scientific studies to see what evidence exists into whether melatonin is useful for insomnia, but the data is lacking.
At best, studies tend to conclude that melatonin may be helpful, but many raise the need for further studies being required to draw solid conclusions.
According to both the American Academy of Sleep Medicine and the American College of Physicians, data is lacking for the use of melatonin in insomnia treatment.10
In agreement with the NHS in the UK, both of these health organisations recommend the use of Cognitive Behavioural Therapy for insomnia CBTi as the first-line insomnia treatment. Itâs this technique that we use at Sleepstation and itâs an incredibly effective way to treat insomnia.

Can Melatonin Supplements Improve Sleep
It is well-established that melatonin produced by the body plays a fundamental role in getting quality sleep, so its natural to consider whether melatonin supplements can be used to address sleeping difficulties.
Research to date has shown that melatonin supplements may be useful in certain situations for both adults and children.
How To Use Melatonin Effectively
Melatonins short half-life is both a blessing and a curse. Because it works quickly and doesnt stick around for too long in your body, its great for preparing your body for sleep and assisting with issues such as delayed sleep onset.
Its also a useful supplement for those nights of occasional sleeplessness, where you may just need a little extra help falling into your normal sleep schedule.
However, because melatonin wears off quite quickly, its important to time your bedtime dose of melatonin so that it kicks in just before you plan to go to bed.
To counter melatonins short half-life, some supplement brands sell extended-release melatonin pills that are absorbed more slowly by your body. These give you a longer window in which you can take melatonin before going to bed.
Although theres no exact time to take melatonin before sleep, taking it 30 minutes to two hours before your ideal bedtime is a common approach. This approach keeps levels of melatonin high right when you get into bed, which is when its needed most as a sleep hormone.
To get the best results from melatonin, try to combine the effects of a melatonin supplement with your bodys natural melatonin production by practicing good sleep hygiene. This means:

What Are The Health Benefits Of Taking Melatonin
Melatonin supplements may help with certain conditions, such as jet lag, delayed sleep-wake phase disorder, some sleep disorders in children, and anxiety before and after surgery.
Jet lag
Jet lag affects people when they travel by air across multiple time zones. With jet lag, you may not feel well overall and you may have disturbed sleep, daytime tiredness, impaired functioning, and digestive problems.
Research suggests that melatonin supplements may help with jet lag. This is based on medium-sized reviews from 2010 and 2014.
- Four studies that included a total of 142 travelers showed that melatonin may be better than a placebo in reducing overall symptoms of jet lag after eastward flights. Another study of 234 travelers on eastward flights looked at only sleep quality and found low-quality evidence that melatonin may be better than placebo for improving sleep quality.
- Two studies that included a total of 90 travelers showed that melatonin may be better than a placebo in reducing symptoms of jet lag after westward flights.
Delayed sleep-wake phase disorder
People with DSWPD have trouble falling asleep at the usual times and waking up in the morning. They typically have difficulty getting to sleep before 2 to 6 a.m. and would prefer to wake up between 10 a.m. and 1 p.m.
Some sleep disorders in children
Because of these uncertainties, itâs best to work with a health care provider if youâre considering giving a child melatonin for sleep problems.
Sleepless Five Things To Know About Using Melatonin Correctly
I cant fall asleep, but melatonin doesnt work for me. Sleep eludes a lot of us, so I hear this fairly often. And almost as often, its because the poor tired person has been taking it wrong. Heres how to get it right.
Melatonin can be a very effective way to help your body sleep better not just longer, or faster, but better, giving your brain the rest and cycles it needs to work well.
Heres some helpful information so you can actually give melatonin a fair try before deciding whether or not it can help you:
1. Melatonin is not a sleeping pill, so taking it just before bedtime will make things worse, not better.
In and of itself, melatonin doesnt make you sleepy or fall asleep. Under normal circumstances, the amount melatonin we have naturally in our body rises in response to when the sun goes down . It tells your brain and body that its the end of the day its basically sends out the hey, its getting dark signal and in response to melatonins natural increase at sundown, the body starts the rest of the biological process of winding down and preparing for sleep which takes a few hours.
The wrong approach, then, is what most people mistakenly do: taking it shortly before you want to fall asleep. You need to take it 2-3 hours before your planned/desired sleep time.
2. More is not better.
In the US, we tend to think that if a little helps, more is better definitely not so in the case of melatonin dosage, where less is more.
3. Light defeats melatonin.

Is Melatonin Safe To Take Every Night
Americans arent sleeping well. Roughly 80% of U.S. adults say they struggle to fall asleep at least one night a week, according to a recent Consumer Reports survey. And research has found that sleep problems are also on the rise among adolescents.

Other Possible Melatonin Side Effects
- Melatonin and birth control effects melatonin supplements may not be safe for women trying to get pregnant. It seems that melatonin has similar effects as birth control, making it more difficult for women to reach ovulation and become pregnant. Some evidence shows that lower doses, up to 3mg are safe, but there is not enough research to prove that.
- Melatonin and bleeding disorders it is believed that regular melatonin intake can worsen the symptoms and effects of bleeding disorders. Studies show that melatonin may slow blood clotting or coagulation, which may lead to excessive bleeding and bruising.
- Melatonin and epilepsy studies and current data show that melatonin can trigger or worsen epilepsy and seizure frequency in some people. While some experts argue otherwise, some professionals do not recommend melatonin intake in people who are prone to having epileptic or other types of seizures not even small doses.
- Melatonin and transplant recipients because melatonin can increase the immune function, it might interfere with immunosuppressive therapy used by transplant recipients.
