Using a phone to read a novel generally does not cause direct harm to the body, but excessive use of the phone may have some negative effects on the brain. When you read a novel on your phone, your brain will constantly receive and process information, which will consume a lot of energy. In addition, reading novels on the phone would also distract the mind and prevent the brain from resting. If one was in such a state for a long time, it might have negative effects on the brain, including memory loss, lack of concentration, mood swings, and so on. In order to reduce the impact of reading novels on the brain, some measures are suggested, such as: 1. Control the time of use and try to avoid excessive use of the phone. 2. Turn off notifications and message reminders so that the phone can focus on reading novels. 3. Regular rest allows the brain to rest and recover. 4. Choose high-quality novels and don't read low-quality or overly stimulating content. Limit the time you use electronic devices to allow your body to exercise and train. Using a mobile phone to read novels may have some negative effects on the brain, but as long as you pay attention to the use of the method and take appropriate measures, you can reduce these negative effects.
