Before humans invented artificial light, we relied on the sun and moon to guide our sleep cycles. With the invention of fire, and eventually the light bulb, we found a way to extend our waking time past the sunset.
Think of your street – do streetlights, porch lights or security lights keep you awake?
Light is not just making you tired
Unfortunately, staying awake longer may do damage to our circadian rhythm, which responds to the natural ebb and flow of darkness in a 24-hour period. Basically, it’s like setting a “reset” button at the end of each day.
Fast Company recently published new research that suggests light pollution may also affect your circadian rhythm, which in turn could affect the way your body releases hormones, its temperature and other critical functions, including fighting off the bacteria and viruses that make you sick. A disrupted circadian rhythm may even put you at risk for obesity, cancer, diabetes and mental disorders.
What can you do to combat the “night light?”
Avoid using electronic devices, such as your computer, tablet or smartphone, before bed and try to dim your lights as much as possible at night, especially if you need to use the bathroom or get a glass of water. Turning on all the lights in your house in the middle of the night will trick your body into thinking it’s morning.
