However, outdoor exercise in the early morning hours of winter has many risk factors, so caution is needed. In particular, people who are at risk of blood pressure and cardiovascular disease or are sensitive to cold should be more careful. Dawn is the coldest time of the day, and cold air causes vasoconstriction, increased blood pressure, and increased heart burden. In particular, if you are at risk of high blood pressure, angina, and myocardial infarction, the sudden cold can be a threat.
Jang Jun-hee, head of the Department of Internal Medicine at Seran Hospital, said "The cold constricts blood vessels, so it raises blood pressure, increases heart rate and stress hormones, causing blood pressure to rise."`"Obesity also activates the sympathetic nervous system, increasing heart rate and blood pressure. In winter, weight gain and the action of the cold itself double blood pressure".
Dawn and morning hours are the time when sympathetic nerve activity increases and morning blood pressure increases. The combination of cold and morning blood pressure increases the cardiovascular burden, and the risk of falls and fractures increases due to the dark environment and the possibility of ice.
Therefore, if you have high blood pressure and heart disease, you should be careful about outdoor exercise. After measuring your morning blood pressure, decide whether to exercise or not, and if your blood pressure is higher than usual, you should postpone your exercise or replace it with indoor exercise. In addition, sudden high-intensity exercise in cold weather raises blood pressure, so it is better to gradually increase the intensity of exercise.
Manager Jang Jun-hee said, `It is recommended to exercise from 10 a.m. to 3 p.m., when there is sunlight in winter, the temperature is relatively high, and the fluctuation of blood pressure is stable. However, it is safe to replace it with indoor exercise on very cold days. "Before exercising, you should warm up for 10-15 minutes to give your skin, blood vessels, and muscles time to adjust to the cold, and pay attention to keeping your ears, hands and feet warm and layering."
