Will I get arthritis?

People often talk about "arthritis" and "rheumatism pain", which is strictly called "osteoarthritis" in the medical sense. It is a joint degenerative disease that often occurs in joints such as the knees, hips, and hands. The most common manifestation is joint pain. It is caused by many factors such as old age, obesity, strain, trauma, estrogen deficiency, excessive exercise, joint deformity, etc., which causes degeneration of articular cartilage, reactive hyperplasia of joint margins and subchondral bone. In other words, you won't get "arthritis" if you don't wear long underwear.

Although cold weather itself cannot cause arthritis, it can aggravate the pain of arthritis patients. Cold weather is not the cause of osteoarthritis, but a cold and damp environment is more likely to cause knee pain to worsen. If you don't pay attention to keeping your joints warm because of the cold weather, you may increase the chance of accidental injury, cause indirect harm, or cause joint burden to a certain extent. Therefore, it is still necessary to keep your legs, especially your knees, warm. Whether it's autumn trousers, woolen trousers or cotton trousers, wear them when it's cold.

Why is it necessary to wear long johns?

1. Protect the knee joint

As an important weight-bearing joint of the human body, the knee joint is most afraid of cold, especially in autumn and winter, when not only the temperature is low but it is often accompanied by cold winds. The cold winds will invade the unprotected knee joints and cause them to catch cold.

2. Improve immunity

Among all parts of the human body, the calves and feet not only have a long distance for blood to flow, but also gather the meridians of the whole body. Therefore, if the feet are cold, the whole body will be cold, the body's resistance will decrease, and viruses may take advantage of the opportunity to enter.

3. Prevent back and leg pain

If you do not pay attention to keeping your legs warm in cold seasons, it will cause low back pain, sciatica, knee pain, etc. over the years.

4. Prevent body damage

Although young people have good heat production function, they are easily damaged by being in a cold and damp environment for a long time, and the disease will occur after middle age, which will pose a hidden danger to health in old age.

When should we start wearing long johns?

Time: There are differences between the north and south

Although "autumn freezing" can enhance cold resistance, it is only suitable in early autumn when the summer heat has not yet subsided. When it comes to late autumn, especially after the Cold Dew, the temperature drops significantly, the temperature difference between day and night changes greatly, and strong cold air often invades, you should add autumn clothes and autumn trousers. For the elderly and arthritis patients living in the southern region, due to the cold and humid climate, they should wear autumn trousers in advance.

Temperature: below 10℃

Taking 10℃ as the boundary, if the minimum temperature is below 10℃, you should wear long johns, and as the temperature drops, the long johns should be appropriately thickened.

Self-perception: Feeling cold legs

If you feel your legs are cold and they take a long time to return to normal temperature after coming back from the outdoors, you should wear warm johns and thick socks immediately when you feel your legs are cold, even if the temperature is not particularly low, and soak your feet in hot water for 15 minutes every day before going to bed.

Sensitive groups should pay attention

The sudden drop in temperature in winter has the greatest and most obvious impact on the elderly, pregnant women, infants and young children, patients with chronic diseases such as cardiovascular and cerebrovascular diseases, respiratory diseases, and people who work outdoors for a long time. Compared with the general population, the above-mentioned groups are more susceptible to cold waves. They should pay attention to adding clothes in time and try to reduce going out. As they age, the body temperature regulation system of elderly patients with chronic diseases is difficult to adapt to changes in external temperature, so they are also sensitive to cold waves.
