Melatonin is the sleep hormone, but it doesn’t just help you drift off at night. It’s an antioxidant, anti-inflammatory, and it even has .
As important as it is, you don’t need to take a melatonin supplement to get better sleep and health.
Below, we'll explain how to naturally increase melatonin levels. We’ll also show you how to use the RISE app to boost your natural production of the sleep hormone and go to bed when your body’s rate of melatonin production is highest for an easier time falling and staying asleep.
“Light is our most powerful tool when it comes to increasing melatonin. Try to get some natural light exposure each morning and day, and then avoid bright light in the run-up to bedtime,” says Dr. Chester Wu, who is double board certified in Psychiatry and Sleep Medicine, and provides sleep medicine services, medication management, and psychotherapy to adults at his private sleep medicine and psychiatry practice.
Here’s how to increase your melatonin levels naturally.
Aim for 10 minutes of natural light exposure as soon as you can each morning. And make that 15 to 20 minutes if it’s overcast or you’re getting light through a window.
If it’s dark when you wake up, try light therapy. Sit in front of a 10,000 lux for 30 minutes. Place the lamp about 16 to 24 inches from your face and positioned over your eye-level at an angle. Then try to get outside when the sun is up.
Light suppresses the production of melatonin by your pineal gland, which is a good thing in the morning. When you get out in natural light, you reset your circadian rhythm — your body’s roughly 24-hour internal clock that helps control your sleep-wake cycle.
Try working by a window, going for a walk, and exercising outside. The more light you get throughout the day, the less sensitive you’ll be to it in the evening, when it can reduce your natural melatonin levels.
One found daytime bright light exposure increased nighttime melatonin compared to dim light exposure.
More research needs to be done to find the ideal amount of light exposure needed during the day, but one of our science advisors, Dr. Jamie Zeitzer, who’s the Co-Director of the Center for Sleep & Circadian Sciences at Stanford University, says an hour or two may be enough, but the more light you can get the better.
Early evening bright light exposure may also help — the key word here is early. A small found bright light exposure from 6:30 p.m. to 9 p.m. reduced how much late evening light exposure (10:30 p.m. to 11:30 p.m.) suppressed melatonin levels.

This is a key behavior to increase melatonin naturally. About 90 minutes before bed, turn off overhead lights and switch to dim lighting, turn on a blue light filter on your TV or the f.lux app on your computer, and put on blue-light blocking glasses. You might want to avoid screen time before bed altogether.
One found exposure to room light in the hours before bed can delay melatonin production and shorten how long your body makes it by about 90 minutes. This was compared to dim light conditions.
If you’re trying to fall asleep earlier, avoiding bright evening light can make a big difference. One found when night owls went camping for a week and were exposed to natural light only — so no artificial light in the evening — their circadian rhythms shifted earlier and looked more like those of early birds.
RISE can tell you when to get and avoid bright light based on your circadian rhythm.
Make your bedroom as dark as possible. Use blackout curtains or blinds, wear an , and turn off or cover up any electronics that emit light.
If you wake up in the night to use the bathroom or check on a child, keep the lights off or as low as possible. The same goes for if you wake up and can’t fall back asleep.
shows room light exposure during normal sleep hours can reduce melatonin levels by more than 50%!
Expert tip: Consider a red light lamp or flashlight if you’re often up at night. shows red light may not disrupt your melatonin secretion as much as blue light.
We’ve covered other reasons why you shouldn’t sleep with the lights on here.
It may make you feel drowsy, but alcohol isn’t doing your melatonin levels any favors. As a general rule, avoid alcohol three to four hours before bed to minimize the risk of sleep disruptions.
One found when participants drank alcohol an hour before bed, their melatonin levels were down by 15% two hours 20 minutes later and reduced by 19% three hours 10 minutes later.
This was after a relatively moderate dose too — about three standard drinks for men and two and a half drinks for women weighing about 154 pounds.

Eating melatonin-rich foods can increase your melatonin levels, but more is needed to know whether dietary melatonin can improve sleep problems. Your diet in your daytime levels of melatonin than your nighttime levels.
Even if it can, the amount of melatonin in a normal portion size may not be enough to affect your sleep.
Dietary sources of melatonin include:
And your melatonin levels may increase as certain foods increase your natural melatonin synthesis, as opposed to you getting melatonin content from the food itself. For example, foods that affect the availability of the amino acid tryptophan, which is synthesized into melatonin, could also impact your melatonin levels if you are tryptophan deficient (this is uncommon but may be true for some vegan or vegetarian diets). Foods high in tryptophan include tart cherry juice, quinoa, and poultry.
The health benefits of melatonin may come from an overall healthy diet, not one specific food. Other factors, like your weight, may have as much of an impact on melatonin as specific dietary choices. And diets rich in fruits, veggies, and grains contain high amounts of melatonin and help keep your weight in check.
Even if melatonin doesn’t help your sleep, it may come with other health benefits. It’s an antioxidant, anti-inflammatory, and may even have cancer-fighting properties.
Beyond what you eat, how much you eat may also make a difference to melatonin. shows cutting your calories or fasting can reduce nighttime melatonin secretion. But again, more research is needed.
Expert tip: Light is much more important than diet for melatonin, however. As one published in Food & Nutrition Research puts it, “Diet and nutrients modulate fluctuating melatonin levels, but the influence is minor if compared with the power of the light-dark cycle.”
As a general rule, avoid caffeine about 12 hours before bed.
Coffee contains melatonin, but it’s not clear whether caffeine can affect your melatonin levels. Some suggest caffeine can increase melatonin, while other studies have found it can reduce nighttime melatonin levels.
Caffeine can definitely affect your sleep in other ways. A found it can reduce your sleep time by 45 minutes — so it’s worth cutting yourself off early.
Cutting yourself off from caffeine at the right time can make sure that you’re not undermining any steps you’ve taken to increase your melatonin levels via light or alcohol timing. You want to feel sleepy (not wired on caffeine) when your body is producing melatonin at bedtime.

RISE can give you an exact time based on your circadian rhythm each day.
Your Melatonin Window is what we at RISE call the roughly one-hour window of time when your body’s rate of melatonin production is at its highest. Going to bed during this window can help you fall and stay asleep more easily compared to going to bed earlier or later. It won’t help increase your melatonin levels per se, but it can help you get the result you’re really looking for: better sleep.
About two hours before your typical bedtime, your body starts producing melatonin. This moment is known as the (DLMO). Melatonin levels rise as it gets closer to your bedtime and they peak overnight.
When it comes to falling asleep fast, the timing of your melatonin production may be more important than your melatonin levels alone. You want your rate of melatonin production to be at its highest around your bedtime to help you drift off. Your melatonin levels could be high — they typically peak early in the night when you’re hopefully asleep — but if you’re trying to go to bed at the wrong time in your melatonin cycle, you may still struggle to drift off.
RISE predicts the timing of your Melatonin Window, so you can go to bed when your body’s more primed to fall asleep. Keeping a regular sleep schedule can help keep your Melatonin Window at a similar time. And avoiding light at the right times can make sure your body starts producing melatonin in the run-up to bedtime.
This feature is a game-changer for RISE users who say it helps them fall asleep more easily:
“This app is life-changing. If I go to sleep according to my schedule, within my Melatonin Window, I am guaranteed to satisfy my sleep needs without any additional sleep aids, supplements, or medications.” .
Your body should produce about (about 0.01 mg to 0.08 milligrams) of melatonin per night. But everybody produces a different amount of melatonin, and it’s tricky to find out if you’ve got low melatonin levels. Plus, even if you do, low melatonin may not be the reason you can’t sleep.
Beyond the above melatonin-boosting tips, try improving your overall sleep hygiene. Light, alcohol, and caffeine timing are just three aspects of sleep hygiene.
Other good sleep hygiene habits include:
RISE can guide you through 20+ sleep hygiene habits at the right time for your circadian rhythm to help you fall and stay asleep.
We’ve covered other ways to fall asleep faster here and how to sleep without any sleeping pills at all here.
If you still struggle to sleep, speak to a healthcare provider about sleep disorders, medical conditions, and medications that could be causing sleep problems. If melatonin supplements are the answer, a doctor can tell you what you need to know about when and how much to take for your situation.
Heads-up: Synthetic melatonin supplements can add to your natural melatonin levels, but you shouldn’t take melatonin every night to fall asleep.
Melatonin use can be safe when used short term to:
Exogenous melatonin (the kind made outside of your body) works best when you take it when endogenous melatonin (the kind made inside your body) is low, like during the day. So supplements aren’t that effective if you take them at bedtime to fall asleep at your usual bedtime.
Supplements also come with potential side effects like daytime drowsiness. They aren’t suitable for everyone (seek medical advice if you’re pregnant for breastfeeding, for example), and they may not be the best treatment for .
Expert tip: Sleep hygiene is the science-backed way to optimize your natural melatonin levels for better sleep, but better sleep starts with knowing how much of it you need to begin with. Check RISE to find out how much sleep you need — it varies from person to person. When we looked at how much sleep 1.95 million RISE users aged 24 and up needed, we found it ranged from five hours to 11 hours 30 minutes. Almost half needed eight hours or more.

Getting light exposure and drinking alcohol close to bedtime can cause low melatonin levels. But so can:
The good news is having lower melatonin levels doesn’t guarantee you’ll have sleep problems.
“There are many people, like those with specific kinds of spinal cord injury, who don't make any melatonin and can sleep just fine,” says Dr. Jamie Zeitzer, the Co-Director of the Center for Sleep & Circadian Sciences at Stanford University and one of our sleep advisors.
You can increase your natural levels of melatonin by getting out in natural light during the morning and daytime and avoiding light and alcohol close to bedtime.
Use RISE to see when exactly you should do these behaviors, as well as other habits that will help you fall and stay asleep.
RISE can also tell you when your body’s rate of melatonin production will be at its highest, so you can harness your melatonin levels and have an easier time falling asleep.
All this can help you get a good night’s sleep in no time — 80% of RISE users get better sleep within five days.
