Caffeine myth or caffeine fact? It's not always easy to know. Chances are you have some misunderstanding about caffeine. Read on. Here are some of the most common myths about caffeine and some facts have been gathered to shed light on them.
Myth one: Caffeine is addictive
Caffeine is a stimulant(起刺激作用的食物) to the central nervous system, and regular use of caffeine does cause mild physical dependence. But caffeine doesn't threaten your physical, social, or economic health the way addictive drugs do. If you stop taking caffeine abruptly, you may have symptoms for a day or more, especially when you have been used to consuming two or more cups of coffee a day. However, caffeine does no cause the severity of withdrawal or harmful drug-seeking behaviors as drugs or alcohol. For this reason, most experts don't consider caffeine dependence a serious addiction.
Myth two: Caffeine probably causes insomnia(失眠症)
Processed mainly through the liver, caffeine has a relatively short half-life. This means you can get rid of half of it within about five to seven hours on average. After eight to ten hours, 75% of the caffeine is gone. For most people, a cup of coffee or two in the morning won't prevent them from sleeping at night. Consuming caffeine later in the day, however, can interfere with sleep. Your sleep won't be affected if you don't consume caffeine at least six hours before going to bed.
Myth three: Caffeine harms children
As of 2004, children aged 6 to 9 consumed about milligrams of caffeine per day. This is well within the recommended limit. However, energy drinks that contain a lot of caffeine are becoming increasingly popular, so this number may go up. Some kids are sensitive to caffeine, developing temporary anxiety or irritability, with a “crash” afterwards. Also, most caffeine that kids drink is in sodas, energy drinks, or sweetened teas, all of which have high sugar content. These empty calories put kids at higher risk for obesity. Even if the caffeine itself isn't harmful, caffeinated drinks are generally not good for kids.
Myth four: Caffeine has no health benefits
Caffeine has few proven health benefits. But the list of caffeine's potential benefits is interesting. Any regular coffee drinkers may tell you that caffeine improves alertness, concentration, energy and clear-headedness. Scientific studies support these subjective finding. One French study even showed a slower decline in cognitive ability among women who consumed caffeine. Other possible benefits include helping certain types of headaches. These research findings are interesting, but still need to be proven.

Yu Xu, one of China's first female fighter pilots who could fly a J-10 jet, died during a flight training in Tangshan in North China's Hebei province on Saturday. Almost all major media outlets have sung high praise for Yu's spirit. People's Daily said: "She died for the peace and happiness of so many families ... The name of Yu and other heroes will be carved not only in stone, but also in the hearts of millions." However, despite being a news hit, a lot of social media platforms still pay much attention to pop stars, no matter their weddings, problematic marriages or just datings. The day Yu died, she did not even make it to the top-10 hot topics on micro blogs.
Some netizens have criticized such people for being too cold to news about heroes who defend our country. They even quoted from the book, Amusing Ourselves to Death, to express their concerns over people being misled by new media while referring to pop stars as "xi zi", a contemptuous(轻蔑的) term used for entertainment stars in the old days.
However, it is unnecessary to shame those netizens who were busy reading about film stars and other celebrities. We live in the age of social and new media, where the celebrities usually draw greater public attention than real heroes. This is partly because the agents(经纪人) of celebrities(名人)are very skilled at using social tools to expand their fan base for commercial gains.
Of course, we should admit the great influence entertainment has on people's minds and it helps the media industry make money. Pop stars do take up a lot of our time, and especially many young people waste their spare energy on them, their new songs, new movies, even rumors about their love life and other scandals. The domestic media industry needs improvement, some entertainment stars should improve their public images, but it is not right to call them "xi zi".
The media may be encouraging people to pay greater attention to celebrities than military heroes, but that does not necessarily mean people pay less respect to heroes than stars. The increasing number of reports about the pilot shows the heroes are worth people's added attention, and they get it.
