In our modern world, many people stay up far too late on their smartphones, tablets, and computers, and this comes at a very hefty cost. Not only does technology keep our brains stimulated at night, but it also can disrupt our sleep, even delaying it for hours past our bedtime. Bedrooms today become a den for games and entertainment, but not so much a good night’s rest.
Exposure to light at night might not seem like that big a deal to you, but remember that before the advent of modern technology, we basically had two lights guiding us at all times – the sun and the moon. These natural lights helped us to see during the day, and lull us to sleep at night. We became accustomed to these natural patterns, waking with the sun and falling asleep with the moon.
