  The Internet plays a big part in human life. People benefit a lot from it.We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.
As far as the Internet being a part of our lives—well,that train has left the station. There is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected with high blood pressure (血压) in a young group: teenagers. 
The study results show that teens who spend at least 14 hours a week online may have high blood pressure, which makes your heart and blood vessels (血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and other diseases.
The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens were described as “heavy Internet users”. And
researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy Web use with high blood pressure.
The lead researcher is Andrea Cassidy Bushrow. She says, “Using the Internet is part of our daily life, but it shouldn’t ruin us.” She adds that it is important for teens to stop to have a rest regularly from their computers or smart phones and do some kinds of physical activities. She also suggests that parents shouldn’t let their children use the Internet for more than two hours a day, five days a week.
