Listening to too many horror novels may have a certain impact on a person's physical and mental health. The specific impact may vary from person to person. Some horror novels may stimulate the nervous system, causing the reader to feel nervous and afraid, which may cause anxiety, insomnia, indigestion and other uncomfortable symptoms. If the readers turn these negative emotions into actions, it may lead them to make some unwise decisions such as excessive dieting, irregular work and rest, etc. Horror novels could affect a person's psychological balance. Some horror novels often depicted some creepy scenes or revealed some dark secrets. If the readers were immersed in such an environment for a long time, it might cause their psychological balance to be disturbed and affect their mental health. However, reading horror novels did not necessarily have a negative impact on one's physical and mental health. Some horror novels may bring some excitement and fun to the readers, but they can also help the readers develop their imagination and thinking ability. If readers could read horror novels with an open mind and control their reading time and frequency, they might gain some beneficial gains from it.
