We’ve all had restless nights. Whether tossing and turning is a nightly occurrence or this is the first time you’re up counting sheep, you’ve likely heard of the popular sleep aid melatonin. But what is melatonin, and how long does melatonin last for sleep?
Melatonin is a naturally occurring hormone that can help promote sleepiness, so you fall asleep fast. Many people have turned to melatonin supplements, which are available over the counter, to help them catch some zzzs in a pinch.
Before using melatonin, it’s essential to understand the potential impacts it can have on your health. Keep reading to learn everything you need to know about using melatonin for sleep.
But how does melatonin affect your body?
Melatonin levels rise in the evening to put you in a state of quiet wakefulness that helps promote sleep. Your body naturally produces melatonin, and taking melatonin in the evenings can help supplement your natural melatonin production to get the rest you need.
How Does Melatonin Work?
Melatonin is produced by the pineal gland of the brain, which transforms serotonin into melatonin when your internal clock sends it the right signal. High melatonin levels cause your blood pressure and body temperature to lower, putting you in the mood for sleep. Additionally, if your body senses that it’s nighttime and your eyes absorb less light; your body will know to switch from serotonin production to melatonin production.
This is one reason why turning down the lights and practicing proper sleep hygiene before bed is so important. If you keep the lights on, your body may have a harder time producing melatonin, meaning that you’re not as prepared for sleep.
How Long Does It Take For Melatonin To Work?
Melatonin supplements typically begin to kick in between 20 minutes and two hours after ingestion, which is why Buenaver suggests taking one to three milligrams two hours before bedtime.
Additionally, natural melatonin levels rise around two hours before bed, so having a consistent bedtime routine can help signal to your body that it’s time to ramp up melatonin production.
Melatonin can affect everyone differently, meaning there’s no single right answer to how long melatonin lasts. You may need to do some trial and error to figure out when to take melatonin before bed and how much to take so you can stay asleep.

How Long Does Melatonin Stay in Your System?
The regular melatonin half-life, or the time it takes for your body to reduce the melatonin by half, is around 40 minutes. This means half of the melatonin is processed in the first 40 minutes, and the other half is processed throughout the rest of the night.
Factors Affecting How Long Melatonin Lasts
But how long does melatonin last in your system? Melatonin typically stays in your system for around four to eight hours, but this range largely depends on external factors, including:
Ø Age: Your metabolism slows as you age; meaning the rate at which your body can metabolize the melatonin also slows. The older you are, the longer it may take for melatonin to wear off.
Ø Caffeine: Research has shown that caffeine can modify melatonin production to counteract the effectiveness of the supplement.
Ø Light exposure: Exposure to bright light, especially the blue light emitted from technology, can send signals to your brain that it’s daytime, making it harder for the melatonin to take effect.
Ø Body size: Factors like your height and weight impact how you absorb melatonin and how it affects you.
Ø Tobacco use: In animal studies, nicotine has been shown to inhibit melatonin’s effectiveness in the body.
Ø Other medications: Additional medications like blood thinners, immunosuppressants, and stimulants may counteract the effectiveness of melatonin.
