Precautions for morning exercise:
First, it is not advisable to get up too early.
At about 4: 00 a.m., blood has the highest viscosity and the worst fluidity, and it is easy to coagulate into thrombus, which hinders blood circulation. This is the time when cardiovascular diseases occur frequently. Therefore, it is not advisable to get up too early for morning exercises, especially for patients with diabetes complicated with cardiovascular diseases. Do not participate in strenuous and strenuous activities during this time. If you have the habit of exercising in the morning and don't want to change it, then you should gradually increase the amount of exercise during this time.
Second, it is not advisable to exercise in the Woods before sunrise.
At night, trees can't do photosynthesis, so they can only breathe. As we all know, trees breathe out carbon dioxide and breathe in oxygen. After a night's breathing, the carbon dioxide content in the Woods is high in the morning, but the oxygen content is low. Therefore, if you exercise in the Woods before sunrise, you will inhale more carbon dioxide, and in severe cases, you will feel dizzy or even faint. Only after sunrise, when the trees start photosynthesis, will the air quality in the forest get better and better.
Third, the strength should not be too great.
Just getting up, the tissues and organs of the body are in a state of inhibition. Sudden and strenuous exercise, the blood flow in the muscle increases sharply, which will increase the contraction intensity and frequency of the heart, and the myocardium will be prematurely tired due to insufficient oxygen supply, leading to chest tightness. In addition, diabetic patients should also prevent hypoglycemia caused by excessive exercise intensity.
Fourth, it is not appropriate to be inattentive.
In the process of morning exercise, if you are still listening to the radio while recording, it will affect the sustained and stable excitability of the central nervous system, cause irregular fluctuations in sports emotions, break the regulation law of the body system, and greatly reduce the effect of morning exercise.
Fifth, rainy and foggy days are not suitable for morning exercises.
Because smog pollution is relatively heavy now, fog droplets contain a lot of pathogenic bacteria and pollutants. At the same time, it is not suitable for doing morning exercises near factories, along highways and crowded places, because serious pollution will do harm to human health.
Sixth, it is not appropriate to exercise in buildings.
Because high-rise buildings often form a "high-rise wind" that is strong and weak, up and down, and constantly changing, people who exercise in this environment are prone to catch a cold and make blood sugar levels change.
