Light affects our biology and that includes artificial light, as well.

From regulating sleep cycles and menstrual cycles in addition to combating tumors, our bodies rely on natural cycles of light and dark to manage our hormones which govern a variety of necessary functions in the human body.

It seems our bodies have yet to adjust to the luminous 24-hour cityscape many of us know today. Considering that artificial light stimulates non-visual systems like hormones, fertility and the sleep-wake cycle, it might be worth it to cut your exposure to TVs and computers a few hours before bed-time and enjoy your shut-eye in total darkness. A happy pineal gland pays off for your body, mind and soul.
