For patients with rheumatoid arthritis, osteoarthritis and carpal tunnel syndrome, soaking the hands in water can relieve morning stiffness, but the water temperature should not be too hot. In addition to soaking hands in hot water, taking a warm bath in the morning and keeping warm at night can help relieve morning stiffness. However, care should be taken to dry them in time to avoid aggravating the symptoms of morning stiffness with wind or cold.
