Regular Sleep = Healthy Pregnancy
Our circadian rhythm is set by the natural light/dark nature of our days and night and is associated with many biological processes. And, as one study found, it can also have a negative impact on female reproduction.
While the exact physiological process is a bit complicated, the authors note that “both stable circadian rhythms and cyclic melatonin availability are critical for optimal ovarian physiology and placental function. Because light exposure after darkness onset at night disrupts the master circadian clock and suppresses elevated nocturnal melatonin levels, light at night should be avoided.”
