However, some of the habitual actions that we usually take for granted are likely to accelerate joint degeneration, and as long as we pay more attention to correcting our behavior, we can maximize joint protection. Going up and down stairs Among all the joints in the human body, the knee joint bears the main weight of the body, and is one of the most vulnerable joints. The knee joint bears 4.8 times the body’s weight when going up stairs and 6.7 times the body’s weight when going down stairs. It is very easy to put pressure on the patellofemoral joint when going up and down stairs for a long time, which can cause pain between the cartilage. Solution: Try to slow down the speed of going up and down the stairs and up and down the slope, you can try to turn sideways 45 to 90 degrees; downhill, try to use the handrail; the elderly can use more crutches, thus reducing the pressure of the body on the knee. Kneeling to wipe the floor Many women are used to kneeling on the floor “wipe the floor” – in fact, this is a very wrong posture, kneeling to wipe the floor, the pressure of the patella will be pressed on the femur, equal to the cartilage between the two bones directly to the ground, a long time, some knees can not straighten, can not get up. Solution: Try not to kneel to wipe the floor, even if you have to kneel to wipe, you can consider a cushion under the knee, and kneeling time can not be too long, it is best to take a break every 10 to 20 minutes, so as to maintain blood circulation, nourishing joint cartilage. If you want to be more comfortable, why not simply sit directly on the floor, or prepare a small bench. Sitting cross-legged Many people like to sit cross-legged, some young people also like to sit cross-legged in bed to use the laptop. In fact, while sitting cross-legged, the knee cartilage has been under pressure, while also bearing the weight of the upper body. If you sit cross-legged using the wrong force for a long time, some people’s knees can even be too painful to get up immediately. Solution: people who have the habit of cross-legged, you can only bend a leg, natural and easy, do not bend both feet together, and do not force the leg down.
