It is not a psychological effect that the weather can affect people’s state of health, according to Lu Liangjing of the Department of Rheumatology at Shanghai Renji Hospital. Foreign studies have been reported, revealing a link between weather and joint pain. Although the exact cause is not known, changes in temperature and air pressure can indeed cause changes in the gravity of the air around joints, which can trigger joint pain. 2007 researchers at Tufts University in Boston, USA, reported results that suggested that every 10-degree drop in temperature can cause an exponential increase in joint pain, while changes in air pressure can also be a trigger for joint pain. Studies conducted on cadavers have shown that atmospheric pressure can affect joints by altering intra-articular pressure. An experiment conducted by researchers found that when the hip joint pressure was equal to atmospheric pressure, the femoral head would be squeezed one-third of an inch out of its normal position. Therefore, every rainy day or weather change, the joint will be painful, stiff and other uncomfortable symptoms, you can take the above-mentioned simple small methods to keep the joint warm, increase blood circulation in the tissues around the joint and relieve pain.
