Most people think using mobile phones for too long is harmful to people's health. Not only does it do harm to the eyesight of mobile phone users, but also it makes them feel pain in their necks. Recently, a research by a phone company in the UK has found something new.
One of the trends (趋势) researchers have found recently is in the thumb (拇指) size of mobile phone users. According to the research of 2, 000 mobile phone users, the sizes of the thumbs of people who spend a lot of time on his or her mobile phone could be 15% larger than the others'. This trend is most often seen in users aged 18-34, and one in eight people have a larger thumb as a result of often using the touch screen smart phones. Not only that, some of these mobile phone users say their little fingers are a little curved (弯曲的) for the same reason.
The same research also shows the average (平均的) time each person spends on his or her mobile phone is two hours a day. 19% of the mobile phone. users say they can't live without a smart phone even. if only for a day. "When these people swipe (滑动) the screen, the muscles (肌肉) of the their thumbs are used a lot for a long time, so that the thumb muscles become stronger. That's why the thumb becomes increasingly bigger, " explained the hand therapist (治疗师) Nicola Goldsmith.
The research doesn't say whether this finding is alarming (令人担忧的). However, the famous doctor Jordan Green said, "The use of mobile phones for a long time without stopping can cause great harm to your muscles and bring you great pain and even illness in the hand." "It's not easy to separate people from mobile phones. Thus, taking a regular (有规律的) rest while using the mobile phones is a good way to protect the thumbs." he added.
