Common Myths About Full Moons


Picture this: a luminous full moon hanging in the night sky, casting a mystical glow over the world below. It’s a sight that has inspired countless myths and legends throughout human history. But how much of what we believe about full moons is based on fact, and how much is pure fiction? In this article, we’ll unravel some of the most common myths surrounding full moons, using scientific evidence to shed light on these lunar misconceptions.

Myth 1: The moon affects human behavior

It’s a tale as old as time: full moons make people act strangely. From increases in crime rates to spikes in hospital admissions, this myth is widespread. However, research tells a different story. A comprehensive study published in the journal “Frontiers in Pediatrics” (2016) found no significant correlation between the full moon and human behavior. This suggests that the idea of the moon influencing our actions is more folklore than fact.

Myth 2: Full moons cause sleep disturbances

Many people report sleeping poorly during a full moon, but is there any truth to this? A study in “Current Biology” (2013) initially suggested a link between the lunar cycle and sleep quality. However, subsequent research, including a large-scale analysis in “Science Advances” (2019), found no consistent evidence supporting this claim. It seems that our sleep patterns are more likely to be disrupted by other factors, such as stress or room temperature.

Myth 3: Full moons influence childbirth

The belief that more babies are born during a full moon is another popular myth. However, a detailed study in “American Journal of Obstetrics and Gynecology” (2005) debunked this myth. After examining birth rates, the researchers found no connection between the lunar cycle and childbirth. It appears that this is another case where anecdotal evidence has been mistaken for scientific fact.

Myth 4: Full moons affect mental health

The term ‘lunatic’ itself stems from the belief that the moon influences mental health. But modern science disagrees. Numerous studies, including one in “Psychological Reports” (1995), have shown no substantial link between the moon’s phases and psychological problems. While the moon may hold a place in folklore, its influence on mental health remains unproven in the realm of science.

Myth 5: Full moons cause epileptic seizures

Another myth suggests that epileptic seizures are more frequent during a full moon. This belief was put to the test in a study published in “Epilepsy & Behavior” (2004), which found no significant increase in seizure frequency related to the lunar cycle. This indicates that epilepsy, like many other medical conditions, is not influenced by the phases of the moon.

Myth 6: Full moons influence animal behavior

It’s commonly believed that animals act differently during a full moon. While some studies, like one in “Behavioral Ecology” (2012), have observed changes in animal behavior, these are more likely attributable to increased light during the night rather than the moon itself. It’s a subtle but important distinction in understanding animal behavior.

Myth 7: The moon’s gravity affects human bodies

Given that the moon influences tides, it’s not a leap to think it might affect us too, since our bodies are mostly water. However, the gravitational pull of the moon is far too weak to have any noticeable effect on our bodies. This illustrates a misunderstanding of how gravity works on a small scale versus a large scale.

Myth 8: Full moons bring bad luck

Many cultures associate full moons with bad luck or negative events. However, this superstition lacks scientific backing. There’s no empirical evidence to support the notion that full moons are harbingers of misfortune. This myth is likely rooted in ancient beliefs and folklore.


The full moon continues to captivate our imagination, but as we’ve seen, many of the myths surrounding it are more fiction than fact. Understanding the moon’s actual influence—or lack thereof—on our world helps demystify this celestial body and allows us to appreciate its beauty without unfounded fears or beliefs.

By examining these myths through the lens of science, we not only enhance our knowledge but also deepen our wonder for the natural world. So next time you gaze up at a full moon, remember the facts behind the fiction and enjoy the view, free from misconception.
