The Earth’s atmosphere is made up of 21% oxygen. Over time this percentage has been very slowly declining, primarily due to the burning of fossil fuels. In major cities, this percentage can be even lower, due to the harmful effects of pollution.
Recently the Guardian newspaper in the UK published an article titled, ‘‘Nearly 9,500 people die each year in London due to pollution – study.” Pollution is deadly and we are all breathing it in no matter where we live in the world. Check out this article to learn which are the world’s most polluted cities.
We are witnessing worrying increases in human illnesses due to the lower levels of oxygen at the cellular level of the body (called hypoxia). Examples include breathing related disorders, asthma, COPD; fatigue disorders, ME, CFS; sleep disorders, etc. With this in mind, it seems safe to assume that none of us are regularly breathing in good quality oxygen like we need to be.
Healthy Oxygen Levels Vital For Good Health
Oxygen is essential for cellular respiration in all mammals (including humans) and without it, we would die. The body uses the oxygen in the cellular mitochondria to help generate something called adenosine triphosphate (ATP), which is the body’s “energy currency” and essential for our bodies to perform their day to day tasks and all normal physiological functions.
