總是感冒,怎麼辦?
It's a yearly occurrence. From the January blues, to spring flu.
流感一年一次，從一月的焦慮到春季流感。There's always one person in your friendship group, at your workplace or in your family who seems immune to all illness. While others around them sniff into their tissues, take paracetamol and drink green tea, they appear fit and healthy. Occasionally, you might even meet someone who claims they have NEVER been ill, making you wonder what their secret is.
你的朋友、同事或家人中總有一個人似乎能對所有的疾病免疫。當別人圍着他們用面紙擤鼻涕、服用撲熱息痛藥、喝綠茶的時候，他們似乎總是很健康。你偶爾還會遇到稱自己從未生過病的人，讓你不禁思考他們不生病的祕訣是什麼。But are they being truthful? Why is it that some people appear immune to illness - while others (perhaps like yourself) get sick every year? Experts are uncertain exactly why some adults never seem to catch the common cold and other illnesses - but they have some suggestions. Here are some of the ideas behind why some of us always get ill - and changes you can make.
但他們說的是實話嗎？爲什麼有些人似乎能對疾病產生免疫--而其他人（或許還包括你）卻每年都會生病呢？專家尚不能解釋爲什麼有些成年人似乎從不感冒或生病--但他們給出了一些建議。以下的一些原因解釋了爲什麼有些人總是生病--以及你可以做些什麼來改變這種狀況。
1. Exercise
1. 鍛鍊In our lifetime, we typically suffer from around 200 bouts of the common cold, each one lasting around five days. We also are struck down by the flu an average of 16 times. Experts believe the better shape your body is in, the easier it is for you to fight off illnesses and infections.
在我們的有生之年，我們通常會感冒200次，每一次大約持續5天。平均而言，我們會患流感16次。專家認爲身體狀況越好，對抗疾病和感染也會越輕鬆。Research suggests people who exercise regularly have a reduced chance of getting ill - possibly because it boosts their immune system. Inactivity can lead to obesity and a huge drop in white blood cell levels - the cells that help us fight off nasty bugs like the common cold. Feeling fit and being active cuts the risk of having a cold by almost 50 per cent, a study in the British Journal of Sports Medicine found.
研究表明，定期鍛鍊的人生病的可能性更低--可能是因爲鍛鍊增強了他們的免疫系統。不活動會導致肥胖以及白血球水平大幅度下降--白血球是幫助我們抵禦普通感冒等病菌的細胞。發表於《英國運動醫學雜誌》（the British Journal of Sports Medicine）的一項研究發現：感覺健康、保持活躍能降低50%患感冒的機率。2. Getting outside as a child
2. 小時候經常呆在外面There is evidence to suggest that the more bacteria and viruses a child comes into contact with, the more resilient their immune system will be as an adult. Scientists call this the "Hygiene Hypothesis". So, if you were allowed to eat worms and play in the dirt as a child, then you could be in luck.
有證據表明，孩子接觸的細菌和病毒越多，他們長大成年後免疫系統的彈性就越大。科學家稱之爲"衛生假說"。所以，如果你小的時候能吃蟲子、玩泥巴，那你就幸運了。Widespread use of disinfectant, antibacterial products and the avoidance of dirt could stop children from developing healthy gut bacteria, research suggests.
研究表明：消毒劑、抗菌產品的廣泛使用，和避免與塵土接觸可能會阻礙兒童發展出健康的腸道細菌。
