Does the human body need air?

Of course the human body needs air. There is no doubt about this. Air is indispensable in our lives. If people lack air, they will lose their lives. Therefore, we must also take better care of the environment in our daily lives.

1. We consume 12 kilograms of fresh air every day. Compared with water and food, air is the largest consumer of the human body. Urban people spend 80% to 90% of their time indoors. In this sense, it can be said that indoor air is our biggest consumable. We can choose water and food, but we cannot choose the air around us.

2. When we get up in the early morning, we often feel chest tightness and difficulty breathing, and we must open the windows immediately to improve the ventilation of the room; when there are many people in a meeting, we often feel dizzy and have to go out for some fresh air no matter what; if we meet someone smoking, we will have more breathing problems; these phenomena occur due to the lack of oxygen in the air, which causes insufficient nourishment to the human brain, which can lead to slow thinking and blurred consciousness, and in severe cases can cause high blood pressure, stroke and other diseases.

3. According to authoritative professional test data, outdoor air quality is at least ten times better than indoor air quality. The only way to enjoy high-quality indoor air is to increase the amount of fresh air (including the size, quality and effect of fresh air).
