#Lunacy has found me full
So, are full moons really associated with changes in mood and mental health? When circadian rhythms wobble, it can cause or increase symptoms of certain mental health disorders, including:ĭoes the full moon still have the power to disrupt your circadian rhythm? It brightens the sky by a lowly 0.1 to 0.3 lux compared with a single streetlight (15 lux) or a cell phone screen (40 lux). Circadian rhythms affect your physical and mental health, too.īut the widespread use of electric light means many of your circadian rhythms are adapting to new light and dark patterns. This has led to the development of circadian rhythms that affect many of your body’s systems - not just your sleep-wake cycle. The human body has adapted to eons of exposure to daylight and darkness. However, this finding conflicts somewhat with other research - including a 2020 study on male athletes that found no significant difference in athletic performance during different lunar phases. In this study, researchers concluded that humans were more physically efficient during full and new moons. Plus, their heart rates returned to normal levels more quickly during full and new moons. Their heart rate and blood pressure were both lower during full and new moons. They found that blood pressure dropped by around 5 mm Hg during new moon and full moon phases. In a 2013 study on male university students, researchers measured the effects of changing lunar cycles on the participants’ cardiovascular systems.
Scientists have wondered whether the changing gravitational pull might also affect how fluids react inside your body. A 2015 study involving 2,125 people found no link between the full moon and changes in sleep patterns.Īs the moon comes closer to the Earth, its gravitational pull changes - and the Earth’s large bodies of water respond with higher tides. Though many studies point to an association between sleep and lunar cycles, not all of them do. However, they didn’t find any association between this change in sleep and significant difference in behavior during that period. They found that the children slept 1 percent less during the full moon phase. In 2016, a group of researchers examined the sleep cycles of children in 12 countries. Many females sleep less and have less REM sleep when the full moon phase is near, whereas males have more REM sleep close to a full moon. May affect men and women differentlyĪ 2015 study of 205 people found that the full moon may affect sleep differently in males and females. Other causes of REM sleep latency can include:ĭeep sleep is believed to occur during your last period of REM sleep. So, increased latency means it takes a longer time to get to REM sleep. Sleep latency is the period between when you first fall asleep and when you enter the first stage of REM sleep. In a 2014 analysis involving 319 people who’d been referred to a sleep center, researchers found that the full moon was associated with less deep sleep and increased REM (rapid eye movement) latency. When the moon is full and bright, it may affect the quality of your sleep.
