Melatonin & Sleep Quality: Finding the Sweet-Sleep Spot

In the quest to conquer restlessness, we often turn to the mysterious workings of melatonin. 

Dubbed the “hormone of darkness,” melatonin has become synonymous with a peaceful night’s rest. However, as we dive into the intricacies of this natural phenomenon we uncover a tapestry far more complex than the common narrative would have us believe.

Melatonin: The Sleep Facilitator

Melatonin is more than just a supplement. Our bodies produce it naturally. 

When the sun sets, the pineal gland kicks into gear, releasing melatonin. This signals that it’s time to wind down for sleep.

However, melatonin doesn’t actually induce sleep. Think of it as a signal, not the engine itself. It tells our system to start the sleep process. But when it comes to taking it in pill form, don’t expect miracles. 

Research shows it may offer only a slight nudge—in fact, just under 4 extra minutes of sleep and a 2.2% bump in sleep quality.

Older adults often benefit most from supplementation. After 65, natural melatonin levels may drop. Here, a little boost can make a big difference for those with insomnia.

Yet, here’s the hitch. The melatonin doses sold are usually too strong—way beyond what the body naturally produces. 

Huberman suggests the sweet spot is between 0.1 and 0.3 milligrams. That’s a far cry from the 5 to 10 milligrams typically found in stores. And these numbers aren’t always reliable; what’s on the label doesn’t always match what’s in the pill.

High doses come with concerns, especially regarding reproductive health. Animal studies show potential effects on fertility, hinting at risks with heavy human consumption.

More doesn’t equal better, especially as a general sleep aid. For some, especially seniors, it has benefits.
