The human body evolved to fall asleep soon after the descent of night’s curtain and to wake with the appearance of the dawn. Sleep cycles were governed by patterns of light and darkness for thousands of years, meaning that for much of history, humanity has enjoyed nine or more hours of sleep each night. Our bodies are naturally encoded to respond to light and dark and sleep with the rhythms of Mother Nature. In the present, artificial light has changed the way we schedule our day-to-day lives, and most of us slumber for less than seven hours at a stretch. It is possible, however, to come back to natural sleeping cycles by making a few small changes. When our bodies and minds are attuned to the world’s natural rhythms, we feel calmer, more centered, and more energetic while awake. Sleep is more satisfying because we afford ourselves more than enough time for restoration and rejuvenation.

Our reliance on indoor lighting further compounds our disassociation from the natural cycles of light and darkness that would otherwise preside over our sleep. You can mimic the passage of the day by changing the quality of the light. Sleeping without heavy drapery or shades is best, so you can wake up with the sun. If sleeping by a window without a curtain is not an option, you can use a dawn simulator lamp that imitates the sun by growing steadily brighter with the coming of morning.

You will likely discover that changing your sleep patterns to be in sync with the daily cycle of light and darkness is easy and that you feel more alive when your sleeping. Your waking rhythms also will be in alignment to those of the Earth. Nature’s own phases will be your guide to wellness, granting you more waking hours in the summertime when you will benefit greatly from spending time outside and ensuring you get plenty of sleep in the winter when you likely need it most.
