It is normal for the heart rate to increase in winter running, which is related to the sympathetic nerve excitation and the increase of the heart’s pumping function, etc. If the heart rate increases after the exercise and accompanied by symptoms such as dyspnea, it is recommended to go to the hospital in time to consult a doctor. Whether it’s winter or summer, when you start exercising, your body’s sympathetic nerve excitability increases, and sympathetic nerve excitability can cause your heart rate to increase. In addition, due to the increase in human muscle activity, oxygen consumption increases, requiring the heart to pump more blood through the cardiac muscle contractility and heart rate increases thereby realizing the heart to maintain the supply of oxygen and energy needed for human activity. This process is physiologic. If the heart rate increases after activity, accompanied by dyspnea, dizziness and other manifestations, there may be heart disease or hypoglycemia and other diseases, it is recommended to go to the hospital in a timely manner.
