A recent study published in the “Science of the Total Environment” journal, conducted by scientists from Uppsala University in Sweden, revealed a surprise for men in particular, when it confirmed that men’s sleep is affected more strongly during the first half of the lunar cycle than women’s sleep.
The new study is more comprehensive and detailed. It was conducted on 852 people (492 women and 360 men), across a wide age range (22-81 years).
While the results of previous studies have been conflicting – to some extent – on the association of the lunar cycle and sleep, the researchers provide an in-depth reading of the effects of the lunar cycle on human sleep in this study.
Among the effects that affect a person in his sleep, and scientists link it to the cycle of the moon; Insomnia, obstructive apnea, which occurs during sleep, when the muscles that support the soft tissues in your throat relax. When these muscles relax, the airways narrow or close, and breathing stops for a moment.
The worst nights for men
The researchers say that men whose sleep was recorded in the first half of the lunar cycle showed lower sleep efficiency and increased wake-up time after the onset of sleep compared to their peers whose sleep was recorded with the waning moonlight.
During the first half of the lunar cycle, the moon is illuminated by the sun (except in cases of lunar eclipses), and thus it is seen bright or bright, then the brightness of the moon begins to decline until it turns from “full moon” to “new moon”.
In contrast, the women’s sleep was monitored during the nights in the first half of the lunar cycle and during the retrograde period, and the researchers found that the women’s sleep was not significantly affected by the lunar cycle.
Scientists say that the mechanisms by which the moon may affect sleep is the sunlight that is reflected on the moon at the times when people usually go to bed, in addition to that, a recent study indicates that the male brain may be more responsive to ambient light than female brain.
It is noteworthy here that humans have believed for centuries that the moon has effects on human behavior, including what the philosopher Aristotle believed that the moon causes madness and epilepsy, and in other cultures it was believed that women give birth at the full moon.
