I often read novels at night until after 11 o'clock. Now (for a long time), I can't sleep well at night because I can't stop thinking about things (dreaming). This was a very common condition known as "night reading disorder." Nighttime dyslexia refers to a situation where it is easy to enter a deep reading state when reading at night, causing difficulty in falling asleep or frequent dreaming. This could be caused by the brain being excited when reading a novel or the brain being active for a long time. In order to avoid night reading disorder, it is recommended to do some relaxing activities before reading at night, such as meditation, deep breathing, listening to soft music, etc., to help relax the body and mind and reduce the excitement of the brain. At the same time, he could also try to change the reading environment, such as dimming the lights and changing the reading materials. If you have tried these methods but still cannot improve your sleep, it is recommended to consult a doctor to find out if there are other health problems.
