Dizziness? Sleepy? Poor memory? These may not be due to insufficient sleep, but insufficient oxygen supply to the brain caused by sitting for a long time in the office and the indoor air is not circulated.
Long-term mental work will increase the oxygen consumption of the brain, while the human body’s intake of oxygen is limited. When the oxygen consumption is greater than the intake, it is easy to cause dizziness, fatigue, poor memory, slow response and other problems. And myocardium can also cause damage.
How to tell hypoxia ?
By monitoring blood oxygen saturation, the oxygen supply of the human body can be judged indirectly. Blood oxygen saturation (abbreviated as SpO2) is one of the important basic data in clinical medicine. The normal value (in plain areas) is 95% to 100%. The low value needs to be paid attention to. It may be due to hypoxia Hypoxia, bronchopneumonia, emphysema, and blood circulation diseases caused by hypoxia, tissue hypoxia.
