Sleep and the Moon: Facts About Sleeping During a Full Moon

You're lying in bed after a long day, but sleep just won't come. Outside, the full moon shines brightly through your window, almost as if it's keeping you awake. Have you ever felt like you sleep worse during a full moon?

Coincidence or reality?

You might wonder whether this is pure coincidence, or whether the full moon really does affect your sleep. You're certainly not the only one who thinks this. Many people report sleeping worse during a full moon. But what does science say about this?

The relationship between the moon and sleep

Let's look together at the relationship between the full moon and your night's sleep. We'll examine how the moon might affect your sleep and what you can do to sleep better, even when the moon is shining brightly in the sky.

What we're going to discover

We're going to look at various aspects of the full moon, from scientific studies to practical tips. So keep reading to discover whether there's a link between poor sleep during a full moon and how you can improve your night's sleep.

The moon and the tides

The moon has a strong influence on the earth's tides. The moon's gravity pulls on the oceans, causing tides. These tides are vital for marine ecosystems. Coastal animals, such as limpets, have adapted to the extreme variations of the tide. They use this cycle for their feeding and reproductive behaviour. Without the tides caused by the moon, these ecosystems would change drastically​​. Moreover, the moon influences not only the tides but also other bodies of water such as lakes and rivers, which in turn affects life in these environments.

Animal migrations and the moon

Many animals use the moonlight cycle as a navigational aid. One example is the Barau's petrel, an endangered seabird species. These birds plan their migrations and breeding cycle around the full moon. By synchronising with the lunar cycle, they significantly increase their chances of survival. This pattern helps them not only with navigation, but also with finding food and evading predators​​. In addition, other animals such as sea turtles and certain species of fish use the phase of the moon to determine their reproductive cycle. This creates coordinated timing that is enormously important for the success of their reproduction.

Research into sleep quality

Several studies have shown that people experience less deep sleep, fall asleep later, and sleep for a shorter time during a full moon. For example, one study found that subjects needed on average five minutes longer to fall asleep during a full moon, slept twenty minutes less, and experienced a thirty percent decrease in deep sleep. These sleep disruptions can lead to fatigue and irritability during the day. Although not all studies confirm this, many results point in the same direction, suggesting that there may be a link between the full moon and reduced sleep quality.

Light and circadian rhythms

The light of the full moon, although less bright than artificial light, can disrupt sleep because our internal 24-hour rhythm is sensitive to light levels. Our biological clock, or circadian rhythm, regulates when we feel sleepy or awake. This rhythm is strongly influenced by light and dark. During a full moon, the nighttime environment is brighter, which can lead to reduced production of melatonin, the hormone that helps us fall asleep. This increased natural light can make it harder for you to fall asleep and wake you up more often during the night.

Evolutionary adaptations

It's speculated that our ancestors used the extra natural light of the full moon to stay active longer for hunting and gathering activities. This could explain why some people are still sensitive to moonlight. In pre-industrial societies, the full moon may have played an important role in nighttime activities, as the extra light improved safety and efficiency during hunting. These adaptations may still influence our modern biological rhythms, keeping us alert and sleeping less well during a full moon.

Emotional and psychological influences

Many people believe that the full moon leads to an increase in crime, violence, and psychiatric problems. However, historical data and modern studies show that there are no significant correlations between the full moon and such behaviour. A study from Switzerland even showed that incidents of violence decreased slightly during the full moon. It seems that these beliefs are based more on myths and folklore than on scientific evidence. Despite the lack of hard facts, the idea of the "crazy" full moon remains persistent in our culture.

Myths and folklore

The moon has always played a major role in much mythology and folklore. Many ancient cultures believed that the moon could cause madness, which is the origin of the word "lunacy". This idea stems from ancient beliefs that have persisted through the centuries. People thought that the changing phases of the moon influenced human behaviour and emotions, leading to stories about werewolves and other mysterious phenomena. These myths have stood the test of time and are still part of our modern culture​​.

Misconceptions and superstition

Despite scientific debunking, many misconceptions about the moon persist. One example is the belief that food can become poisonous during a lunar eclipse. This kind of superstition often reflects deep-rooted cultural traditions and fears that have been passed down from generation to generation. Although there is no scientific evidence to support these beliefs, they remain a persistent part of folklore in various cultures​​.

Practical tips for better sleep during a full moon

• A fixed bedtime routine: A consistent sleep schedule can work wonders for your sleep. Try to go to bed at the same time every night and get up at the same time, even on weekends. This helps your body develop a fixed sleep rhythm. For example, by reading for half an hour before bed or taking a warm shower, you signal to your body that it's time to relax and prepare for sleep.

• Keep your room dark: The light of the full moon can be quite bright and disrupt your sleep. To prevent this, you can use blackout curtains to keep your bedroom dark. A sleep mask can also help keep the light out. In addition, it's important to limit the use of electronic devices that emit blue light before you go to bed. Blue light can disrupt the production of melatonin, the hormone that helps you fall asleep.

• Breathe in, breathe out: Relaxation techniques such as breathing exercises, meditation, and gentle yoga can help your body and mind settle down before bed. Breathing and sleep is a combination that can sometimes use an extra nudge. Try, for example, deep belly breathing or progressive muscle relaxation to release tension. Meditation can help clear your mind of the day's worries, which is beneficial for a good night's sleep.

• Eat healthily: What you eat and drink can have a big impact on your sleep. Avoid caffeine and heavy meals in the evening, as these can keep you awake. Instead, choose light snacks such as a banana or a handful of nuts if you're hungry before bed. Also make sure you drink enough water during the day, but limit your fluid intake right before bed to avoid nighttime trips to the bathroom. Drinking alcohol before bed is also not a

The moon and our sleep

Although scientific studies show mixed results regarding the influence of the full moon on sleep, many findings suggest there may be a subtle impact. The light of the moon, our biological rhythms, and cultural influences all seem to play a role. Some people genuinely experience reduced sleep quality during full moon nights, while others aren't affected at all.

Being mindful of the full moon

It's clear that the moon plays a role in our lives and perhaps even in our sleep habits. By adjusting your sleep rhythm and being mindful of the effects of the full moon, you may be able to improve your night's sleep. Think of practical tips such as minimising light exposure, creating a consistent bedtime routine, and practising relaxation techniques.

Improve your night's sleep

Regardless of whether you believe in the influence of the full moon, following good sleep habits can help you sleep better. Experiment with different techniques to see what works best for you. Don't forget that a good night's sleep is important for your overall wellbeing and health.
