Pregnancy Over 40, Ovulation Is Key To Get PregnantI've written before about the importance of melatonin (which is stimulated by darkness) when you're trying to conceive.

In addition to incorporating Dr. Price's principles into their diets, many women with irregular cycles have benefitted from addressing their night-lighting situation. Exposure to light at night can inhibit the pineal gland's production of melatonin. The pineal gland directs your body's rhythmic activities--including sleep, appetite, and the onset of puberty--through its production of melatonin. This hormone is primarily secreted at night, and it requires darkness to be produced. Bright light suppresses melatonin secretion.2

The hypothalamus gland, also located in the brain, is richly supplied with melatonin receptors. This gland regulates your body's overall homeostasis, including things like blood pressure, emotions, temperature, and the endocrine (hormonal) system. Hormones secreted by the hypothalamus stimulate the anterior pituitary gland to secrete its hormones; and these, in turn, stimulate the thyroid gland, the adrenals and the ovaries to secrete yet other hormones. The ovaries (and the testicles) are also thought to contain melatonin receptors.3
You can see how melatonin production--and thereby sleeping in darkness or with light--can affect the whole body's functioning, including the menstrual cycle: if the hypothalamus doesn't receive sufficient melatonin, its ability to regulate the hormonal system will be impaired...
...Other clinical researchers have also found that sleeping in the absence of light (introducing it for a few days each cycle, or sleeping only in the absence of light) can help women in a variety of situations to strengthen their cycles.6,7
