沉迷上网影响免疫力更易感冒
How being addicted to the internet could make you sick: Too much time online weakens the immune system, increasing the risk of colds and flu
Spending too much time online can increase your risk of catching a cold or the flu, scientists have warned.
科学家近日警告,上网时间过长会增加患感冒和流感的几率.
Those with greater levels of internet addiction are more likely to succumb to illness, than those who spend fewer hours online.
那些网瘾更严重的人要比上网时间较短的人更易生病.
Researchers at the universities of Swansea and Milan believe the reason lies in the fact people with an internet addiction are more secluded, and as a result have weakened immune systems.
斯旺西大学和米兰大学的研究人员认为造成这一结果的原因是沉溺于网络的人更喜欢足不出户,因而导致免疫系统下降.
They said the lack of interaction with other people and less time spent outside exposing themselves to germs played a role.
研究人员表示,缺乏与他人的互动以及在户外接触细菌的时间较短也是一方面原因.
Past studies have also found people who spend more time online experience greater sleep deprivation, have worse eating habits, engage in less exercise and tend to smoke and drink more alcohol.
以往的研究还发现上网时间较长的人往往睡眠不足更严重,饮食习惯较差,锻炼得更少,并且更可能吸烟酗酒.
These behaviours can harm their immune system and increase vulnerability to diseases.
这些不良行为都会破坏人体免疫系统,增加得病几率.
Professor Phil Read, from Swansea University, said: 'We found that the impact of the internet on people's health was independent of a range of other factors, like depression, sleep deprivation, and loneliness, which are associated with high levels of internet use and also with poor health.'
斯旺西大学的费尔•里德教授（Phil Read）说："我们发现网络对人类健康的影响与抑郁、睡眠不足、孤独等一系列其他因素并不相关.这些问题被认为与高频度的上网和健康状况差有关."
Researchers evaluated 500 people aged 18 to 101 years old.
研究人员针对18岁到101岁间的500人进行了评估.
They found that those who reported problems with excessive use of the internet also suffered more cold and flu symptoms than those who spent less time online.
他们发现,那些有过度上网问题的人比上网时间较短的人出现了更多的感冒和流感症状.
Around 40 per cent of the sample reported mild or worse levels of internet addiction - a figure which did not differ between males and females.
