achooThe UK has been enjoying some lovely summer weather recently. Brits have been making the most of the sunny spell by flocking to the beach and having barbeques in their gardens.
But there is often an unwelcome accompaniment to the sounds of sizzling sausages on the barbeque and buzzing bees in the flowers. The clamour of sneezing and people blowing their noses makes an unpleasant soundtrack to Britain's best summer weather. What is going on?
It is hay fever, an allergic reaction to pollen from trees, grass and other plants. When the pollens come into contact with the tissue inside the nose, they start an immune reaction that causes sneezing, itching and a runny nose.
Between 15 and 20% of people in the UK are thought to be affected by hay fever, with the numbers being even higher among teenagers.
Allergy specialist Professor Stephen Durham has calculated that the number of sufferers has doubled over the last twenty years. What is causing the rise?
"There's some evidence that pollution exacerbates it," he says. "And you've also got the hygiene hypothesis - that our bodies aren't as strong because we aren't exposed to infections when we are small children that our systems rebel against."
There is interesting evidence from Austria to suggest that hay fever is related to living in an increasingly sanitised environment.
Researchers there found that young children in regular contact with farm animals are less likely to develop allergies later on. Children living on farms were found to be three times less sensitive to hay fever and nearly four times less likely to suffer from asthma than those living in a non-rural environment.
Perhaps the worst news for hay fever sufferers is that their ailment can never be cured completely. So perhaps it's time we got used to a... a... a... achoo!最近的英国一直沐浴在风和日丽的夏日之中。人们涌向海滩，在自家的花园里烧烤，尽享这段阳光持续明媚的日子。
但伴随烤架上香肠滋滋作响与花丛间蜜蜂嗡嗡低鸣而来的不速之客可就不那么招人喜欢了。人们打喷嚏和擤鼻涕的声音给明媚的英伦夏日带来了不和谐的声音。究竟是怎么一回事呢？
元凶其实是枯草热。这是一种对草木以及其他植物花粉的过敏反应。当花粉与鼻腔内的组织发生接触时会引起喷嚏，发痒和流涕等免疫反应。
据信有15%-20%的英国人患有枯草热，而这一数据在年轻人中甚至更高。
过敏症研究专家斯蒂芬.达拉谟教授得出的数据称枯草热患者人数在过去的20年间翻了一番。是什么导致了感染人数的上升呢？
“有证据表明污染加剧了枯草热感染率,”他说道。“现在有这么一个卫生学假想：我们身体系统所抵触的这种感染是我们在孩提时没有碰到过的。因此我们的身体便无法抵御它了。”
一条来自奥地利的有趣的证据表明枯草热与日益清洁卫生的生活环境中有密切关系。
奥地利的研究者发现经常与农场动物接触的小孩子长大后出现过敏的情况较少。比起居住在非农村地区的孩子们，在农村长大的孩子患枯草热的概率要小三倍，患哮喘的概率要小四倍。
或许对枯草热患者而言最不幸的消息就是他们的这个小毛病是无法彻底治愈的。或许我们该试着习惯阿…阿…阿嚏！
