Using artificial lighting at night can trick your brain into thinking it’s still daytime. But light exposure at night can be problematic, especially in the 90 minutes before bedtime. That works out perfectly in the morning, as exposure to sunlight can help you feel more awake as you start your day.

For a more in-depth look at what does melatonin do, head here. The RISE app can predict your circadian rhythm and tell you when your Melatonin Window is each night, so you can aim to go to sleep in this roughly one-hour window, meaning you can skip the supplements altogether. The tricky thing is the timing of your Melatonin Window can change each day depending on how much sleep you got the night before. Going to bed during this window will give you the best chance of falling asleep quickly and staying asleep through the night. In the RISE app, we call this your Melatonin Window.

The melatonin your brain produces helps regulate your circadian rhythm - the internal clock that tells your body when to sleep and when to be awake over a roughly 24-hour cycle.Įven though melatonin is naturally produced by your body, over-the-counter melatonin supplements (exogenous melatonin) are also available. Melatonin is a naturally occurring hormone that promotes sleepiness. We’ll explain how good sleep hygiene - especially being strategic about the timing of your light exposure - can help you make the most of your body’s natural melatonin production for optimal sleep and daytime energy. But our main goal is to share tips on how you can get the sleep you need without spending a dime. Rest assured, this article will answer your questions about melatonin supplements.
