The idea that weather influences aches and pains has been around since ancient Greece.
天气影响周身疼痛的说法自古希腊开始。
And most of us probably have that relative who swears their knee always knows when there's a storm comin.
大多数人可能都有这样的亲戚，他们总说自己的膝盖能够预知暴风雨。
But while studies show that a lot of people believe this is true, the actual evidence to back it up is mixed at best.
虽然研究发现许多人都相信这是真的，但至少支撑这一观点的真实证据却很模糊。
In 1995, scientists surveyed 558 chronic pain patients living in four cities across the US
1995年，科学家调查了生活在美国四座不同城市的558名慢性疼痛患者
and most of them reported that changes in the weather affected their pain.
其中大多数都称天气的变化影响他们的疼痛。
That's only what the patients thought was happening though,
这仅是患者的想法，
the researchers didn't actually find a correlation.
研究员并未真正找到其中关联。
A 2007 study looked at 200 people with knee pain from osteoarthritis where the cartilage that cushions the bones is worn away
2007年的研究调查了200名膝痛患者，他们都因缓冲骨头的软骨被磨损而患有骨关节炎
and the data they collected over three months did suggest a link between some weather changes and reported pain.
研究员们在过去三个月收集的数据确实暗示一些天气变化和报告疼痛之间有关联。
People's pain went up a smidge with increasing atmospheric pressure and decreasing temperature.
人类疼痛随着增强大气压强和下降的温度也有些许变化。
This doesn't quite fit the my knee can predict the rain idea though,
这和我的膝盖可以预测雨天的想法并不相符，
higher atmospheric pressure usually means nice weather on the way not storms.
更高的大气压强通常意味着好天气而不是暴风雨。
This is because when atmospheric pressure is low,
这是因为当大气压强低降低，
air molecules get pushed from nearby higher pressure regions into the low-pressure one,
空气分子从附近的高压区域被挤压到低压区域，
this makes wind and usually brings along the ingredients for rain.
这就形成了风并且为下雨创造了条件。
When air pressure is high though, things tend to stay nice and stable.
当大气压强足够高时，一切就会易保持美好和稳定。
That being said changes in air pressure can affect our bodies.
这就是所谓的大气压强的变化可以影响我们的身体。
For example, a difference in air pressure between the outside and those little hollow bits in your skull called sinuses
例如，户外和你头盖骨那些被称为鼻窦的空空的小孔之间的大气压强的不同
can lead to a pretty bad headache.
会导致相当严重的头疼。
So there's a chance that the nerve endings in the uncushioned bones of osteoarthritis patients
因此，可能骨关节炎病患无垫骨中的神经末梢
could respond to pressure changes and ache, too.
会对气压的变化和疼痛有所反应。
But larger and more recent studies have had more negative results.
但更大范围和更近期的研究却得出了更加负面的结果。
Like a 1997 review of 16 studies on joint pain and weather couldn't conclude anything for sure
比如1997年在对16项对关节痛和天气的研究进行回顾时，并未得出准确的结论
and one study from 2016 looked at 345 osteoarthritis patients on Australia for three months
以及2016年对澳大利亚345名骨关节炎患者进行了为期三个月的研究
who reported their pain online when it got worse.
病患会在骨关节炎加重时在线进行记录。
The researchers took temperature, humidity, atmospheric pressure and precipitation data in the places where the patients lived.
研究员在患者生活的地方收集了气温、大气压强以及降雨数据。
Both at the times they reported pain and when they didn't as a control,
他们同时会记录疼痛并与没有疼痛记录的情况作对照，
and overall they couldn't find any connection between changes in the weather and people's pain.
总的来说他们没有找到天气变化和人类疼痛之间的任何关联。
A similar study looking at lower back pain in 981 Australian participants couldn't find any link to weather either
在一项对981名澳大利亚参与者的下腰痛研究中也并未找到任何与天气变化的联系
and they looked at factors like wind speed and direction, too
他们也查看风速和方向等因素。
some pain triggers like stress and weight gain are absolutely backed up by science
一些触发疼痛的因素，如压力和体重增加绝对得到了科学的支持
but weather, not so much at least as far as we know right now.
但至于天气，至少目前我们还不清楚。
