However, this is one of the common causes affecting sleep quality that not everyone realizes.
According to a survey on the sleep health of Chinese people in 2025 cited by Xinhua News Agency, up to 48.5% of adults experience sleep-related problems and this situation tends to increase with age. Experts warn that the use of electronic devices before bed is contributing to increasing difficulty falling asleep and not sleeping deeply.
Notably, people who spend more than 3 hours a day using social media are 2.3 times more likely to experience sleep disorders than those who use less. Each hour of exposure to electronic screens can reduce 10-20 minutes of deep sleep in the body.
According to experts, blue light emitted from smartphones has the ability to reduce the secretion of melatonin - a hormone that plays an important role in regulating sleep. Not only that, continuously receiving information from social networks, short videos or entertainment content also causes the brain to maintain a state of excitement, prolonging the time spent going to sleep.
Experts recommend limiting the use of phones and electronic devices for at least 30 minutes to 1 hour before bed. Instead, people can read books, listen to light music, meditate or perform relaxing breathing exercises to help the body fall asleep more easily.
A small change in evening habits can be the key to significantly improving sleep quality and long-term health.
