天气变化与头疼微妙关系
春天开始的时候，花儿盛开，冬天的第一场雪，随着感恩节的临近，叶子变成棕色……我们都知道天气变化的感觉，以及它如何改变我们的生活。
What we can also sometimes be aware of is a physical sense of things being a little different when this happens, and sometimes it's a little difficult to put our finger on why that is. "Changes in weather are basically challenges to our immune system and to our musculoskeletal system," family medicine physician Vikash Modi told Piedmont Healthcare. When the weather changes, our bodies change too, adapting to our new environments to keep our lives in harmony and our bodily systems working correctly.
我们有时也能意识到，当这种情况发生时，事物会有一些不同的物理感觉，有时我们很难弄清楚为什么会这样。“天气的变化对我们的免疫系统和肌肉骨骼系统是一个挑战，”家庭医学医生Vikash Modi告诉皮埃蒙特医疗中心。当天气变化时，我们的身体也会发生变化，以适应新环境，使生活保持和谐，以及身体系统正常工作。
And sometimes, our bodies undergo changes that are pretty wild — and pretty extreme. From spring to summer, fall to winter, we've taken a look at the interesting changes that happen to your body when the weather starts to turn, and anything you need to watch out for when this happens.
有时，我们的身体会经历非常剧烈的变化。从春天到夏天，从秋天到冬天，我们来看看当天气开始转变时，你的身体会发生什么有趣的变化，以及当这种情况发生时你需要注意的任何事情。
When it gets colder, you get more headaches
天气变冷时，你会更头疼
Most of us have experienced the dreaded brain freeze from scarfing cold ice cream too quickly at some point or another. Well, as it turns out, cold weather can induce a similar painful sensation in your head and, in both situations, it's down to your blood vessels.
我们大多数人都有过这样或那样的经历:由于吃完冰淇淋太快，大脑会被冻住。事实证明，寒冷的天气会在你的头部引起类似的疼痛感，在这两种情况下，都会影响到你的血管。
With a brain freeze, your body reacts to the extreme cold by quickly expanding the blood vessels in your brain to create warmth, inducing pain (per the Cleveland Clinic). When it's cold outside, though, the opposite can happen. "One of the causes of headaches is constriction of blood vessels in the brain," said Tri-City Medical Center internist Xiang Li to Women's Health Magazine. "Cold weather can cause blood vessels to quickly narrow, reducing the flow of blood."
当大脑冻结时，你的身体对极端寒冷的反应是迅速扩张大脑中的血管以产生温暖，并引起疼痛来应对极端寒冷。然而，当外面很冷的时候，就会发生相反的情况。“头痛的原因之一是脑部血管收缩，”三市医疗中心内科医生李翔对《女性健康》杂志说。“寒冷的天气会导致血管迅速收缩，减少血液流动。”
When this happens, headaches can occur and, in more extreme circumstances, cold weather can cause migraines, which can be decidedly more difficult to deal with. Migraines can also be triggered by other weather changes, like particularly stormy weather or bright sunlight. If you notice that you're experiencing head pain during cold weather or any other weather change, it's worth keeping a note of any triggers you notice and discussing them with your doctor to determine a course of action.
当这种情况发生时，可能会发生头痛，在更极端的情况下，寒冷的天气可能会导致偏头痛，而偏头痛显然更难处理。偏头痛也可能由其他天气变化引起，比如暴风雨天气或明亮的阳光。如果你发现自己在寒冷的天气或任何其他天气变化时感到头痛，就应该记录下你注意到的任何诱因，并与你的医生讨论，以决定如何采取行动。
