I don’t need a calendar to know when the moon is full. I can feel it.
There’s a certain clarity in my mind—like fog has lifted and I can think more clearly. I sleep a little lighter, yet I wake up feeling surprisingly alert. There’s this underlying sense of well-being I can’t quite explain, but I know it’s tied to that bright, glowing moon hanging in the night sky.
At first, I thought maybe it was all in my head. After all, we’ve all heard people blame everything from mood swings to wild behavior on the full moon. But could there really be something to it? Could the moon actually be affecting me—and maybe even you—in subtle ways?
So, I did a little digging. And what I found might surprise you.

🌕 Is There Any Science Behind This Feeling?
We know the moon affects the tides—so it seems natural to wonder if it might affect us too, especially considering that the human body is made up of roughly 60% water. That’s a theory that gets passed around a lot: “If it pulls on oceans, surely it’s tugging on us too!”
But according to physicists, it’s not quite that simple. Tides happen because the moon’s gravity creates a difference in pull between one side of the Earth and the other. Our bodies, being much smaller than oceans and having fluids mostly bound up in cells and vessels, aren’t affected in the same way. So, scientifically speaking, the moon’s gravity isn’t pulling at our cells like it does the sea.
But here’s where it gets interesting…

🛏️ The Full Moon & Sleep Patterns
Several studies have shown that sleep can be disrupted around the full moon—even in people who weren’t aware of the lunar phase.
One Swiss study published in Current Biology found that during a full moon, participants:
-
Took 5 minutes longer to fall asleep
-
Slept 20 minutes less
-
Spent 30% less time in deep (NREM) sleep
-
Had lower levels of melatonin, the hormone that helps regulate sleep
And that’s not the only research. A 2021 study showed that people across different cultures and environments consistently went to bed later and slept less in the days leading up to the full moon. Some experts think this might be because of ancestral instincts—maybe our bodies are wired to stay alert under moonlight, like our ancestors once did.
🧠 Clear-Headed or Sleep-Deprived?
Now here’s the twist: we tend to associate less sleep with sluggishness and brain fog, but in some people—like me—it seems to do the opposite. I feel more alert, more creative, and somehow more in tune with my thoughts.
Could it be that small shifts in sleep architecture are nudging my brain into a different kind of rhythm—one that feels fresh and productive?
Maybe. Some researchers suggest that the light from the full moon may influence our internal clocks, impacting everything from hormone release to mood regulation. Even if it’s subtle, those little changes might be just enough to make certain people feel a mental shift.
💬 So… Is It All in My Head?
Maybe. But that doesn’t make it any less real. Science is still exploring how lunar phases affect our biology, and not everyone will notice the same effects. Some studies even suggest that people who believe the moon affects them may be more likely to experience those effects—a kind of mind-body feedback loop.
But here’s what I know for sure:
Every time the full moon rolls around, I feel it.
In my thoughts. In my energy.
In my deep breath under a moonlit sky.
And if you’ve ever felt something stir inside you during the full moon—whether it’s restlessness, reflection, or clarity—maybe you feel it too.
🌟 Final Thoughts
Whether it’s rooted in sleep cycles, hormone shifts, or simply a beautiful connection to nature, the full moon has a way of getting our attention. For some of us, it’s more than just a pretty sky—it’s a rhythm we can feel in our bones.
So the next time the moon is full, take a moment to notice how you feel.
Who knows? You might just discover that you’re more in tune with the moon than you ever realized.
