“Melatonin doesn’t work for me.” I hear this fairly often, and almost as often, it’s because the poor tired person has been taking it wrong.
Here’s 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 doesn’t 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 (when there’s less available light). It tells your brain and body that it’s the end of the day – it’s basically sends out the “hey, it’s getting dark” signal – and in response to melatonin’s 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.
I cringe when I hear that people have been taking 10mg doses. At most, the average adult should take no more than 2mg to help with sleep, and there are studies showing that even that is often too much – the correct dose might be closer to just 5% of that (100 to 150 micrograms, depending on size and weight).
(Note that if you have higher dose melatonin and want to try to reduce the dose by cutting the pills, you shouldn’t cut time-release melatonin – it effectively means you’re taking more all at once.)
3. Light defeats melatonin.
If you correctly take melatonin 2-3 hours before you want to fall asleep, but you continue to be exposed to bright light or “blue light” (such as every electronic screen you own, from your mobile phone to the TV), your body is getting mixed messages, and taking melatonin won’t help.
So (and you’re not gonna like this, sorry): Two to three hours before your intended bedtime, turn off the electronic screens (or at least use an effective blue light filter), and turn down the ambient lighting. Also the “warmer” (more yellow) the light from your lamps, the better, since “cooler” lighting tells your body it’s daytime, defeating your body’s preparations for sleep.
4. Melatonin isn’t necessarily the answer, even if it does help you fall asleep more easily.
There are many reasons why we have trouble falling asleep and staying asleep, and chronic use of sleep aids, including melatonin, can “hide” the problem temporarily. The underlying problem, however, doesn’t get addressed.
For example, it might be a problem with your sleep-wake cycle related to a circadian rhythm disorder, and melatonin supplementation can’t repair that (better: well-designed light therapy).
What’s true for many is that sleep issues stem from problems with stress, anxiety, or depression — any of which can cause difficulty falling asleep, staying asleep, or getting deep restful sleep. Psychotherapy can be highly effective for helping with sleep and related mood problems, and there are also excellent results from CBT-I (Cognitive Behavioral Therapy for Insomnia). It can be hard to find a CBT-I trained practitioner, but here is a link to a review of some of the online options: http://www.sleepreviewmag.com/2014/12/online-options-insomnia-therapy/
If you aren’t back to being able to sleep well on your own after taking melatonin for 2-3 weeks, looking into the possibility of an underlying sleep disorder, or finding more effective ways to solve the stress, anxiety, or other mood issue you might be dealing with, is the next step. You shouldn’t take melatonin chronically or long term to sleep, primarily because you risk “masking” the real underlying issue that can cause other problems.
5. Melatonin and daytime don’t mix.
Keep in mind that melatonin as it occurs naturally in the body doesn’t have much of a daytime presence, so if you take melatonin too close to morning (such as if you wake up at 4am and erroneously take some to get back to sleep), or during the day, you can set yourself up for not just being drowsy and groggy, but potentially even depressed.
There are ways to use melatonin during the day to adjust your sleep cycle (for example, to prevent or reduce jet lag, or if you work night shifts), but for those who are simply struggling to sleep well at night, keep melatonin away from daytime hours.
