Can achy joints really forecast the weather?

關節疼痛真的可以預測天氣嗎？

Maybe. A change in barometric readings may be part of the reason: Atmospheric pressure often drops right before bad weather sets in; this shift could cause body tissue to expand, which can lead to swelling and pain.

也許吧，氣壓變化有可能是一部分原因：壞天氣來臨時，氣壓往往會降低，這會導致機體組織擴張，會讓人感覺疼痛。

The effect is slight, but people who have arthritic or inflamed joints may detect the difference.

這種影響是十分輕微的，但如果有人患了關節炎又或關節受傷，影響或許會增大。

Temperature may have an impact too: In 2007, researchers found that every ten-degree drop in temperature corresponded with a small increase in osteoarthritic knee pain.

溫度也是一方面原因：2007年，研究者發現氣溫每降低10度會增加膝骨關節炎的疼痛程度。
