Scientists have long recognized that the light Facilitates human activity, be it light the sun Or moonlight or artificial light.
In fact, it appears to be an effect the moon, The only dependent of our planet, is clear on "Sleep" About humans, according to a scientific study published recently.
The study revealed that our ability to sleep is clearly affected by the lunar cycle, even when industrial sources of light are taken into account, according to the British newspaper The Guardian.
Using wrist monitors, the researchers tracked Sleep patterns I have 98 individuals living in 3 indigenous communities in Argentina over a period of one to two months.
These three societies were divided as follows: A rural community that does not have it ElectricityAnother rural community has limited access to electricity, while the third community is located in an urban setting and has full access to electricity.
Participants in all three communities showed the same pattern of sleep oscillations as the moon advanced through a 29.5-day cycle, with sleep duration changing between 20 and more than 90 minutes, and varying times. Sleep 30 to 80 minutes.
The study authors found that the participants’ peak sleep in each community was lower, and staying late before bedtime occurred in the three to five days leading up to the full moon nights, and the reverse happened in the nights before the new moon appeared.
The study’s author, professor of biology at the University of Washington, Horacio de la Iglesia, said the data was somewhat surprising, because the initial prediction was lack of sleep and increased activity on full moon nights.
و .ضاف "But it turns out that the nights before a full moon are the nights when the most moonlight is during the first half of the night".
Unsurprisingly, the data showed that "Lunar phase effect" Sleep appears stronger the more access to electricity is limited.
In an effort to confirm their findings, the researchers compared their results with similarly collected data from 464 students in a city Seattle In Washington state, they study at the University of Washington, and they find the same fluctuations in sleep patterns.
The researchers wrote in a journal "Science Advances" That these results together "It strongly suggests that human sleep coincides with the phases of the moon regardless of ethnic, social, cultural and level of urbanization background".
De la Iglesia added: "We humans tend to believe that we somehow manage to control nature, and use it Industrial light, Is a great example of this. But it turns out that there are some forces of nature that we cannot dismiss".
However, professor of sleep and physiology and director of the Sleep Research Center at the University of Surrey, Dirk Jan Dyck, indicated that the researchers did not address internal influences, such as biological clocks, that could affect sleep patterns.
The results of previous research on the effects of the moon on sleep seemed inconsistent. Studies have reviewed sleep in the laboratory (where the study samples are protected from external light) and most of them are not designed to specifically look at the impact of the moon, said Dr. Siro della Monica, a research fellow. At the Sleep Research Center in Surrey.
Della Monica said: "The study is very exciting, but as the authors themselves say, they cannot prove a causal relationship .. However, the data is strong and new".
