Mask has become one of the essential items in life. Some people are exercising. When they exercise their bodies, they occasionally forget to pick off the mask; others are worried about the risk of epidemic or air pollution, and put on the mask during exercise.

However, when a mask exercise suddenly happened, it was inevitable that it was inevitable that when exercising and exercising, do you want to wear a mask? Will it cause damage to the body?

If you want to figure out this problem, let's take a look at the two real experiments first.

The CCTV News Life reminder column group went to the Heart Rehabilitation Center of the Beijing Rehabilitation Hospital for a group of tests under the guidance of a doctor. Two middle -aged sports masters wearing disposable medical masks for exercise, doctors conducted a comprehensive analysis of their physical signs and related data with professional testing equipment.

It was found that when the two experimenters wearing a mask and not wearing a mask walked on a treadmill at a speed of 3 km/h, the data differences of the body were not large.

However, when the speed of the wallet was increased to 8 km/h, within twenty minutes without a mask, the heart rate of the two experimenters was about 150, and the blood oxygen saturation was 99%. When wearing a mask to do the same exercise, about three minutes, the physical index of the two experimenters appeared more obvious fluctuations. The blood oxygen saturation dropped significantly to 97%, and the heart rate reached about 200.

Our normal people's blood oxygen saturation should be more than 98%, and less than 95%will be in danger of life, and once the heart rate exceeds 200, this means that the heart is undergoing too much pressure in the heart, and it is likely to face extremely dangerous conditions. Essence

South Korea ’s Yanshi University has also done similar experiments, testing the changes in the human body when wearing a high -performance mask (such as the N95 mask).

The results showed that when the testers were wearing a mask, the number of heartbeats, blood pressure, and blood oxygen saturation were not much different. When the walking speed is accelerated, the shrinkage voltage of the experiment has risen from 124mmHg to 141mmHg, and arterial blood oxygen saturation decreases from 96%to 95%.

Through these two experiments, it can be seen that whether it is a one -time medical mask or a stronger mask such as N95, there is no problem with the low -intensity exercise such as slow walking and other low -intensity. influences. If strenuous exercise is performed, even if it is a healthy adult population, it may cause the body to compensate the disorders and increase the burden on the lungs and the heart. If the exercise causes the mask to be wet by sweat, the danger will be greater.

Ma Shuai, a physician of the emergency department of Beijing Chaoyang Hospital, pointed out that many people feel uncomfortable when we wear a mask, and even sitting quietly, they will feel uncomfortable. Mainly because the space of the back of the mask is blocked, the nose airflow will turn on the nose or the cheeks on both sides of the cheeks.

When wearing a mask exercise, the breathing frequency increases, and a large amount of water mist condensing when the mouth and nose breathing together, which will increase the feeling of holding the breath during breathing to a certain extent. For people with good health and normal cardiopulmonary function, short -term breathing will not cause severe hypoxia, but for patients with decline in lung function, wearing masks for a long time may occur in hypoxia, which will cause myocardial muscle to suffer Damage, increase the risk of exercise.

So, does some fitness experts think that "wearing a mask can enhance cardiopulmonary function and achieve the effect of altitude training"? "

Yuan Bing, deputy director of the Department of Respiratory and Critical Medicine of the First People's Hospital of Yunnan Province, said in an interview with Xinhua News Agency that athletes exercise in a relatively hypoxic high altitude environment, which can increase the oxygen carrying capacity of blood red blood cells and improve cardiopulmonary function. And wearing a mask exercise, artificially causes hypoxia. From a certain perspective, similar to plateau training, but the difference is that professional teams have scientific system support. Physical function reaction.

There are many uncertainty of ordinary people wearing masks to simulate plateau training, such as mask types, masks closedness and exercise intensity. If you blindly choose to wear masks for strenuous exercise, you may cause excessive body hypoxia. Essence

It can be seen that ordinary people wearing a mask exercise violently, not only failing to achieve fitness purposes, but in the long run, there will be a burden on gravity and lung function.Experts remind that it is not recommended to perform strenuous exercise when wearing a mask, such as strenuous running, football, basketball and other competitive sports or competitive sports.You can choose a relatively soft way of exercise, such as slow walking, Tai Chi, Yoga, etc.

If you really don't worry about safety, you can use the ventilation valve mask or sports protective mask to reduce the sense of breath.

At the same time, prepare a few more masks, and replace it in time when the mask is soaked by sweat to avoid using sweaty masks.
