Osteoarthritis is a common joint disease in middle-aged and elderly people, mostly seen in the cervical and lumbar spine and knee and hip joints, such as cervical spondylosis, lumbar spondylosis, and osteoarthritis of the knee or hip joints. So, how to prevent and treat osteoarthritis in daily life? 1, physical therapy: hot water bath or other simple heat therapy given to the affected joint can help reduce pain. However, if the bone and joint pain is caused by trauma, do not rush to use heat therapy, otherwise it will cause joint bleeding and more swelling and pain. 2, exercise: exercise issues should be viewed in two ways, the correct and appropriate exercise can prevent, delay and slow down the process of osteoarthritis. Beneficial exercise includes swimming, walking, cycling, supine straight leg raise or resistance training and non-weight bearing joint flexion and extension activities; incorrect excessive exercise includes climbing, climbing stairs or squatting up and down activities. 3, pay attention to a reasonable diet: overweight can also lead to the occurrence of osteoarthritis. Therefore, patients should ensure a reasonable diet and increase calcium intake to prevent overweight. Special lifestyle can produce special strains on certain joints, causing, or even aggravating, osteoarthritis, such as sleeping on soft beds, high pillows, squatting to eat, and long hours of physical labor can have an impact on the joints, so protecting your joints does not have to start with good lifestyle habits.
