Osteoarthritis can benefit from soaking the feet in warm water, slightly hotter if possible, as the feet have numerous nerves. This can promote blood circulation and facilitate metabolism, such as the elimination of bodily waste, which is beneficial, especially for middle-aged and elderly people, in preventing cardiovascular and cerebrovascular diseases. Osteoarthritis depends on the location and is a chronic joint disease. Its primary pathological change is the degenerative alteration of the joint cartilage. Typically, this condition affects middle-aged and older individuals, more so women than men. Early changes include the deterioration of the joint cartilage, leading to the exposure of the subchondral bone, which can then cause periostitis, changes in the joint capsule, and surrounding muscles. Usually, it presents as rest pain, which may decrease with light activity. Treatment often involves nonsteroidal anti-inflammatory drugs or intra-articular injections of sodium hyaluronate for lubrication and joint protection. In severe cases, joint replacement, such as knee replacement, may be necessary. Thus, soaking the feet can be beneficial for those with osteoarthritis.
