Swiping your phone before going to bed has become a “sense of ritual” for many people before going to bed. Recent studies have shown that swiping your phone for 8 minutes before going to bed will excite your brain for 1 hour. Experts remind that excessive use of mobile phones before going to bed will affect the release of melatonin from the amygdala in the brain, making it difficult for people to fall asleep, delaying the time to fall asleep, and reducing sleep quality. If you use your mobile phone at night, you should lower the screen brightness of your mobile phone or use night mode to reduce the stimulation of the retina by blue light. Put down your phone and rest early!
