When carbon dioxide concentration of indoor air reaches OR exceeds 1000 ppm, people start feeling tired and uncomfortable.
If we stay in an environment with insufficient oxygen supply for a prolonged period of time,
it will cause fatigue, dizziness, insomnia, memory loss, lack of appetite and other chronic fatigue syndromes,
affecting people’s intellectual functionality and efficiency.
Nobel prize winner Dr. Otto Warburg also reminds that
“the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar (anaerobic respiration).”
So how to improve the indoor oxygen is very important to our health and the health of our family members.
Without water, a person can survive for more than a week.
Without food, a person can survive for more than a month.
Without oxygen, the brain will be damaged within minutes.
Oxygen plays an integral part in your health!!
