Movies are a great means of entertainment for many. There are some advantages of watching movies. Comedies, for example, help lower your blood pressure. When you laugh for extended periods of time, your blood vessels(血管) become wider. Intense laughter for 15 minutes during a film has the same effect on your cardiovascular(心血管的) system as exercising. Besides, when you watch a sad movie, you’re more likely to come away from it thinking about loved ones and feeling happy about what you have.
Watching movies can make you creative. A study showed that young children who watched short clips from Harry Potter, specifically ones that involved the use of magic, scored significantly higher in a creative thinking test than children who had watched something else. Moreover, movies are very useful for enhancing individuals’ mental health. They enable people to take time to really relax and momentarily forget about their daily concerns and problems.
However, watching movies aren’t always beneficial. Studies have shown that some people get real pleasure out of being scared by horror movies, but in various ways they may be risking their physical and mental health without even knowing it. When you watch an intense scene in a movie, your heart rate and blood pressure increase. Meanwhile this change in your brain chemistry reminds you of times when you were in a similar state, even if you have no idea you even had those memories. So if something horrible happened to you, being scared again by a movie can unintentionally make you relive it.
Scientists, politicians and parents have debated for decades if being exposed to movie violence leads to actual real-life violence. Overall the answer to that is probably still up in the air, but a new study seems to prove that watching aggression on screen can contribute to being a bully(欺凌行为) in real life, even if it is just in the short term.
In conclusion, certain movies play a positive role, but not all movies do. It depends completely on the subject matter of the movie. So it’s always advisable to choose the movies concerning something positive.
