Adults should be careful too, according to the doctor, who says longer virtual reality experiences can lead to balance problems. You should be careful of your surroundings and be careful not to trip over wires(电线). Those with heart conditions are advised not to play.
But there are some positive health uses of virtual reality. The technology has been used to treat conditions like fear of heights, and it’s also being used to help treat addictions(瘾)．
“What we’re trying to do is take people into a drug-related setting and let them experience cravings (extremely strong wishes for something)，” Dr.Zach Rosenthal with Duke University said. He and his team take addicts inside a virtual house and use a series of tones to condition them to reduce their cravings.
A lot more research needs to be done about the long-term health effects of VR, but in the meantime you had better spend only a limited time on VR and make sure your children use it as little as possible.
