Running at night will not affect sleep because proper physical exercise, especially when the body is slightly tired is more conducive to sleep improvement. If the patient has just started running, the pain of muscles as well as joints will appear in the first few days of running, which may have some effect on sleep. When it is tolerated, the pain of muscles and joints will be reduced and it will have no effect on sleep. Therefore, it is recommended to do appropriate aerobic exercise after dinner, such as running or walking, which has a good effect on the improvement of sleep. In the case of arthritis or rheumatoid arthritis, running afterwards may affect sleep because the patient has joint problems. Running may cause localized friction in the joints, resulting in more pronounced pain, which is more pronounced at night. When the pain is more intense it may have an effect on a person’s sleep. Patients with bone and osteoarthritis are advised to run or exercise under the guidance of a physician.
