Tonight marks the biggest supermoon of the year, a spectacle that stirs the imagination and inspires countless myths and beliefs. Many people associate full moons with chaotic behavior, strange occurrences, and even shifts in mood. While this idea has been around for centuries, the question remains: is there any scientific basis to the belief that full moons can truly cause chaos?
The belief that full moons can influence behavior dates back to ancient times. The term "lunacy" itself originates from the Latin word "luna," meaning moon. In many cultures, full moons were thought to trigger erratic behaviors, including madness and violence. Even in modern times, some people believe that full moons can affect crime rates, hospital admissions, and even sleep quality. These beliefs, often referred to as the "lunar effect," persist despite mixed scientific evidence.
There is some scientific research suggesting that full moons can have subtle effects on behavior, although these effects may not be as dramatic as folklore suggests. One of the most studied areas is the relationship between lunar phases and sleep. Some research has indicated that the full moon can influence sleep patterns. For example, a study published in the journal Current Biology found that participants took longer to fall asleep and experienced shorter, less deep sleep during full moon phases. This disruption in sleep may be linked to the brightness of the moonlight, even if it isn't directly perceived by the sleeper. However, not all studies have found a significant connection between lunar cycles and sleep disturbances, suggesting that other factors, such as personal beliefs or environmental conditions, may play a role.
The idea that full moons can increase crime rates or hospital admissions has also been explored. A study published in the Journal of Emergency Medicine found no significant increase in emergency room visits during full moons. Likewise, research on crime rates during lunar phases has yielded inconsistent results, with some studies reporting slight increases in violent behavior, while others found no association at all. These inconsistencies suggest that any potential influence of the full moon on human behavior is likely minimal and may be overshadowed by other factors, such as seasonal variations or cultural influences.
Another area where the lunar effect is often discussed is in relation to mental health. Some studies have explored whether full moons can exacerbate symptoms in individuals with psychiatric disorders. A review of psychiatric hospital admissions conducted by the American Journal of Psychiatry found no strong evidence to support the idea that full moons trigger worsening symptoms. This suggests that while some people may feel more restless or anxious during a full moon, it may not be directly caused by the lunar phase itself but rather by social and psychological expectations.
Interestingly, the moon's influence on animals has been better documented than on humans. Some studies have found that marine animals, such as corals and certain fish, time their reproductive activities with the lunar cycle, likely due to the moon’s gravitational pull affecting tides. Additionally, some nocturnal animals may become more active during full moons due to increased visibility, while others may reduce their activity to avoid predators. These effects in the animal kingdom provide some insight into how lunar cycles might exert subtle influences, although translating this to human behavior remains challenging.
While there is no definitive scientific evidence proving that full moons cause chaos, the perception of their influence persists. It’s possible that the belief itself contributes to a phenomenon known as the "self-fulfilling prophecy," where people's expectations lead them to behave in ways that confirm their beliefs. In this case, if people anticipate chaotic events or feel more restless during a full moon, they may be more likely to attribute any unusual occurrences to the lunar phase.

While the full moon’s mystique is enduring, the notion that it causes chaos remains more rooted in cultural folklore than in scientific fact.
