Healthy people are suitable for running in cold weather, because in cold weather, blood circulation in the body will slow down, so running can increase blood circulation in the body, promote metabolism in the body, help to increase cold tolerance and improve sleep quality.
But it is not suitable for cardiovascular disease, serious knee injury, asthma and elderly people running in cold weather. Details are as follows:
Slow blood flow in cold weather and accelerated heart rate during running will increase the burden of heart pumping in patients with cardiovascular diseases, leading to aggravation of the disease. Secondly, when the weather is cold, muscle viscosity is high, ligament elasticity and joint flexibility will deteriorate, and joint mobility of patients with serious knee joint injury will decrease. If you exercise at this time, it will not only increase the burden on your knees, but also increase the risk of being injured again. For asthma patients, cold air will stimulate the respiratory tract and may induce asthma attacks. If you don't see a doctor in time, it will even lead to life-threatening, so it is not suitable for running in cold weather. Finally, the elderly themselves are relatively lacking in bone and muscle strength. If you have cardiovascular and cerebrovascular diseases, the chances of running in cold weather will be higher, so the elderly are not suitable for running in cold weather.
