The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language. We use the Internet to connect with family and friends and stay in touch with issues 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. That expression means there is no going back. If you prefer boating, you can say that ship has sailed.
So, there may be 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 to high blood pressure in an unlikely group -- teenagers.
The study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure.
High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke.
High blood pressure can also cause heart and kidney disease. It is also closely linked to some forms of dementia, a brain disease.
