The human body has an adaptation process to the drop in temperature, the temperature gradually drops, the human body's reaction is not strong, and can gradually adapt to this cold environment, when the environment suddenly becomes cold, we often can not adapt, especially the elderly and patients with various chronic diseases, blood sugar and blood pressure will rise. If left unattended, severe cases can lead to conditions such as myocardial infarction, cerebral infarction, and cerebral hemorrhage. In addition, many elderly friends will choose to exercise in the morning, and here I will tell you the precautions.
1. The temperature difference between morning and evening in winter is large, the temperature is low in the morning, and it is not suitable for morning exercise, so exercise when the wind is beautiful at 9 or 10 o'clock, and bask in the sun to promote calcium synthesis and absorption.
2. Exercise should be moderate, aerobic exercise should not be less than 30 minutes a day, exercise should have a certain intensity, and it should be persistent, generally not less than 3 times a week, 20 40 minutes each time. It is advisable to exercise without increasing heart rate, or although the heart rate increases significantly, it will gradually return to normal after a short period of rest, and it is not accompanied by chest tightness, shortness of breath, cough, chest pain, etc., and it is advisable to feel good.
The last thing to pay special attention to is to "wake up slowly", wake up in the early morning and refresh for 5 minutes before getting up and moving. Because the vascular strain of the human body is the worst in the early morning, sudden activity is easy to cause cardiovascular and cerebrovascular diseases.
