Watching horror movies is generally not harmful to your health. However, if the audience is too addicted to watching movies, they will have fear after watching movies. For example, they dare not stay at home alone, and they always feel that someone is waiting when they walk at night.
Generally speaking, horror film mode can be divided into psychological mode and visual mode.
Generally speaking, Japanese horror films are mainly psychological, which is more destructive to the audience.
Vision is generally dominated by American films, mainly because of nausea. This kind of lethality is small.
For psychological horror films, we should be optimistic and remind ourselves that this film is an entertainment film to avoid psychological shock.
