Do you have trouble getting to sleep? It turns out the light bulb is the culprit. Before light bulbs became common, around the turn of the 20^th century, people rarely had trouble sleeping because their body clock told them to sleep when the sun goes down and wake up when the sun rises. And if you take away artificial light, studies show that people's sleep problems disappear!

So, how do we get our sleep back on track? Caffeine’s not the answer and neither are sleeping pills. Most scientists agree that the best way to get a good night's sleep is naturally - by changing our behavior. Go to bed at the same time every night - avoid artificial light from screens, which our brain interprets as sunlight - and try relaxation techniques like yoga to quiet your mind. Scientists say those simple things can dramatically improve the quality and quantity of your sleep. I think those examples might explain why reading over watching TV at night helps many people including myself get to sleep easier.
