爱上网的人容易感冒
Spending too much time online can increase your risk of catching a cold or the flu. Those with greater levels of internet addiction are more likely to get ill, than those who spend fewer hours online.
Researchers at the universities of Swansea and Milan believe the reason lies in the fact that people with an internet addiction have weakened immune systems. They said the lack of communication with other people and less time spent outside exposing themselves to germs played a role.
Past studies have also found people who spend more time online experience greater sleep disorder, have worse eating habits, engage in less exercise and tend to smoke and drink more alcohol. These behaviors can harm their immune system and increase chance to diseases.
Professor Phil Read 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.”
Researchers surveyed 500 people aged 18 to 101 years old. They found that those who reported problems with much use of the internet also suffered more cold and flu symptoms than those who spent less time online. 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. People who had greater levels of internet addiction had around 30 per cent more cold and flu symptoms than those with less internet usage.
And researchers found people who are addicted to the internet may suffer from great stress when they are disconnected from the net. This cycle of stress and relief associated with internet addiction may lead to changes in levels of cortisol, a hormone that impacts on the immune system.
