Smartphones and Sleep
Many people have a habit of looking at their smartphones before going to sleep. However, this can be bad for their health. The screens of smartphones and computers produce a special kind of light called "blue light." When our eyes see blue light, our brains think it is still daytime. This stops the body from making melatonin, a hormone that helps us feel sleepy. As a result, people may have a hard time falling asleep or may not sleep deeply.
To get a good night's sleep, doctors suggest turning off electronic devices at least an hour before bed. Instead of looking at a screen, reading a printed book or listening to relaxing music is a better way to prepare for sleep. By changing our nighttime habits, we can wake up feeling much more refreshed the next morning.
