My tip of the hat to those hunkering down to weather the cold on both the US and Chinese east coasts. Take care, keep warm, stay safe.
The greek "rheuma" meaning "catarrhal flow" (cold), and the Chinese "风湿" meaning "wind & dampness", sum up the popular belief that cold and wet weather conditions can worsen (or possibly even cause) arthritis and rheumatism. Is there a scientific basis?
I get this a lot: patients swear by Thor that their joints hurt more when it rains more, or that their disease flares up during the cooler months. In the absence of good evidence to corroborate their experience, I hypothesise that wind chill may cause vasoconstriction, thereby resulting in ischaemic aches in scarred tissues and damaged joints.
Not that we can do anything about it, but the weather does serve as a talking point.
