Busting Summer Myths

Here are a few truths about the adages you may have heard over and over again in your childhood.

·Wait 30 minutes after eating to go swimming

False. No need to wait 30 minutes. The body produces enough blood and carries enough oxygen to digest food and move your arms and legs. For competitive swimmers however, incorrect eating can cause cramping, but not to the point of drowning due to cramps.

以下是几则你可能童年时就听说过一遍又一遍的神话的真相。

·餐后三十分钟才可以游泳

破解夏日神话的6个真相

错误。不必等待30分钟。身体会产生充足的血液并且运输足够的氧气去消化食物并运动你的四肢。然而，对于竞技游泳运动员而言，不正确的饮食可致痉挛，但并不至于由痉挛导致溺亡。

·If water is stuck in your ear, stand on one foot and tilt your head

False. Your ear canal is curved, so just tilting your head often isn't enough to release the water. The better move: Tilt your head so the waterlogged ear faces down. Place the tip of your index finger in the cuplike spot at the bottom of your ear, and position your thumb behind the ear on the cartilage above your earlobe. Hold firmly and wiggle your ear to straighten the ear canal and dislodge the water.

·如果水堵塞了你的耳朵，单脚站立并倾侧你的头部

错误。因为你的耳道是弯曲的，所以仅倾侧头部仍不足以让水流出。更好的举措是：倾侧你的头，让进水的耳朵朝下。把你的食指尖放在你耳朵靠底部的像杯状一样的位置，并把你的大拇指放在耳后的耳垂上方的软骨位置。牢牢抓紧这两处的同时摇晃你的耳朵，以致耳道拉直并排出水。

·You'll get sick walking in and out of air-conditioned buildings

False. Simply going from a cool room to the outside won't make you sick, but going from an indoor clean environment to an outdoor dirty environment can inflame allergies.

·频繁进出有空调的建筑物会使你生病

错误。仅仅是从一个凉爽的房间走到外面去是不会使你生病的。但是从一个室内的干净的环境走到一个户外的不洁的环境则可能会引发过敏反应。

·Placing open wounds in the ocean will help healing

False. While salt-water may be cleansing, the water in the ocean is far more complex and dirty with bacteria and animals life. I mean, fish pee in there.

·把开放性伤口浸泡在海水中有助其愈合

错误。尽管盐水具有清洁伤口的作用，但是海水的成分却远更复杂，也因为有细菌和动物生态而更脏--我的意思是，鱼类可是在那里随地小便的。

·Scratching bug bites will make them worse

Yeah, don't scratch bug bites, it makes them worse. Not only can the germs and bacteria on your hands infect the wound, scratching actually intensifies the itch by inflaming system messenger proteins. Use ice or a cold cloth to sooth irritated areas.

·抓挠蚊虫叮咬处只会使其更糟

正确。不要抓挠被虫子叮咬的地方，这只会让患处恶化。不仅仅是你手上的细菌会感染伤口，抓挠的动作本身也通过刺激体内信使蛋白而加剧了叮痒感。应该用冰块或者冷冻的毛巾舒缓患处。

·Urinating on jellyfish sting myth

Bad idea. It can only make matters worse. Double negative.

·在水母蜇伤处撒尿的传说

错误。这只会让事情更糟糕。简直是雪上加霜。
