Arthritis and the weather

Arthritis patients often feel more severe joint pain before rain or snowstorm comes; When seasonal changes such as vernal equinox and autumnal equinox approach, symptoms of rheumatism will also appear. as time passes

Some experienced patients can predict the weather changes, and the accuracy is sometimes as good as the weather forecast. So, what does arthritis have to do with the weather?

It will aggravate the symptoms: someone has done an experiment: a "climate control room" has been specially built, which can control and automatically record five climate indicators at will.

(temperature, humidity, air pressure, airflow and ionization). Then let arthritis patients who know nothing about the experimental situation live in the "climate control room"

The researchers observed them scientifically. The results show that the symptoms of these patients get worse when the humidity increases and the air pressure decreases.

Persistent high humidity and low air pressure will not aggravate the symptoms. This result is consistent with the phenomenon that many patients feel worse symptoms before the weather changes such as rain and snowstorm. In patients with arthritis,

80%- 9 0% have this phenomenon, and other 10%- 20% are not affected by weather changes.

Some people may wonder why arthritis patients can "predict weather changes" and why they are so sensitive to weather changes. studies have shown

When the humidity increases and the air pressure decreases, the liquid in normal human cells oozes and the urine volume increases to adapt to the external weather changes. And arthritis patients.

Joint pathological tissues can't discharge fluid with the weather change, which makes the intracellular pressure in the inflamed area higher than that in the surrounding normal tissues, leading to aggravated pain and local swelling.

Not a cause: arthritis is closely related to the weather.

But this does not mean that weather changes are the cause of arthritis. Arthritis patients are all over the world. In the past, it was thought that the incidence of arthritis was related to the cold and warm climate, and the incidence of arthritis in tropical areas was low.

Cold may lead to arthritis. However, subsequent surveys show that the incidence of arthritis in Ecuador and Puerto Rico near the equator is almost the same as that in Hiroshima and Nagasaki in Japan.

; Finland, located between the Arctic Circle, has a lower incidence rate than the Netherlands. So, so far, it has not been proved that the weather can cause any kind of arthritis.

There is no correlation between geographical latitude and the onset of arthritis. This is related to the rainy days in summer.
