Looking for a son? He sleeps in the dark and respects your circadian rhythms

Are you looking for a son? Bedroom too bright at night could make it difficult conception. Or at least that's what several researchers write in a study published Aug. 20 in the online journal Cell Reports.

It would appear in fact that female fertility is linked to a good biological clock -controlled operation of circadian rhythms. If these are stoned, they could make it difficult to conceive, particularly if you are no longer young. And this rate would in fact impaired in the presence of “light interference “.

What is the circadian rhythm?

It ' a cycle that accomplishes approximately every 24 hours, with which are repeated regularly certain physiological processes. For example, the alternating phases between sleep and wakefulness. Many body processes follow this rhythm.

What to do then?

Close the shutters well before bedtime, avoid rooms too bright at night and do not use tablets and phones, as well as the bright computer screen. Try to be more regular and avoid shifts that impair sleep.

The research published by Cell Reports was conducted by Japanese and American scientists on female mice. Scholars have busted the circadian rhythms of female rodents and found that their chances of getting pregnant had fallen by much. An effect that in particular concerned the middle-aged rodents and anyway reversible, eliminating factors that disturb the circadian rhythms (for example, irregular and too lit environments meals) .

The study covers the rodents, but “preserve the biological clock precision - set to the sunlight and not on artificial - can be a key element for the fertility of women," assures Gene Block, University of California. “In modern society, the female population is exposed to too many environmental interference that may play a role in the conception difficulties " . A problem that affects a pair of seven and often cannot find a reason.

Darren Griffin, University of Kent and sleep specialist, says research at Daily mail: “The rats are certain men , and women a proper alternating light-dark experience can only possibly face a problem . " But despite this we must not underestimate the message that fertility is linked to the "state of general well-being. And this should not be underestimated. "
