The moon, with its 29.5-day cycle around the Earth, has long fascinated humanity. Phenomena like the blue moon, blood moon, and lunar eclipses continue to captivate our imagination. Given that the moon, along with the sun, controls the tides, it’s no wonder that some people believe it may also influence the water in our bodies, and by extension, our sleep. In fact, many claim to experience poorer sleep during a full or new moon. But is there any truth to this?

The moon and sleep: what does science say?

The idea that the moon affects sleep has been around for centuries, but concrete scientific evidence remains limited. However, several studies suggest that the full moon may indeed disturb our sleep patterns.

One study published in Current Biology found that it takes longer to enter REM sleep, the dreaming phase, during a full moon. Another study showed that people slept, on average, 25 minutes less on nights when the moon was full. Sleep quality also appears to suffer, with research from 2014 revealing that deep sleep decreased by up to 30% during this lunar phase.

Why do some people sleep worse during a full moon?

Several theories attempt to explain why some people struggle to sleep when the moon is full.

Moonlight and sleep

A common theory suggests that the full moon’s bright light disrupts sleep by interfering with circadian rhythms and reducing melatonin production, the hormone responsible for regulating sleep.

While this seems like a plausible explanation, in today’s world, we are constantly exposed to artificial light, which is far stronger than moonlight. Additionally, sleeping in a dark bedroom with blackout curtains should minimize the impact of moonlight in the bedroom.

Biological rhythms

Another theory proposes that, much like the tides, our bodies are subtly influenced by the moon’s cycles. Since the human body is largely composed of water, the full moon might affect our internal biological rhythms. However, more research is needed to validate this idea.

Full moon and HSPs

Highly sensitive people (HSPs) may be more attuned to environmental changes, making them more vulnerable to the full moon’s effects. This heightened sensitivity can result in restlessness and disturbed sleep, as the increased stimuli during this phase make it harder to fall or stay asleep.

Electromagnetic fluctuations

One hypothesis suggests that the moon’s movement through the Earth’s “magnetotail” during its full phase could cause changes in the Earth’s electromagnetic field. A study indicated that these fluctuations may influence biological processes, potentially causing symptoms like headaches and insomnia.

However, other research has found that electromagnetic fields have little to no impact on sleep, leaving us with more questions than answers about the full moon’s real effect on our rest.

Does the new moon affect sleep?

While the full moon often gets blamed for sleepless nights, the new moon can also impact sleep. During this phase, the moon is invisible, creating complete darkness. Some people find it harder to fall asleep or sleep restlessly during this time, potentially due to the disruption of natural light patterns. Additionally, some theories suggest that changes in energy or biological rhythms may occur during the new moon, further affecting sleep.

Tips for sleeping better during all moon phases

Whether the full or new moon disrupts your sleep, there are ways to improve your rest. Here are a few tips to help you get better sleep during these lunar phases:

  • Keep your bedroom dark: Use blackout curtains to prevent any (moon)light from disturbing your sleep.
  • Practice relaxation techniques: Try meditation or deep-breathing exercises before bed to calm your mind and body.
  • Stick to a regular sleep schedule: Maintain consistent bedtimes, even during different moon phases.
  • Reduce screen time: Avoid electronic devices before bed, as the blue light can interfere with melatonin production.
  • Create a calming bedtime routine: Establish rituals that help you unwind, such as reading a book or enjoying a cup of herbal tea.
  • Invest in a good mattress: A mattress tailored to your body and sleep position can make a significant difference, especially when you’re more sensitive to external factors like moon phases.
