When inadequate or sub-par levels of oxygen exist for long periods, significant health problems often develop.

Oxygen deficiency, also known as hypoxia, develops when the body’s tissues don’t receive the amount of oxygen needed to function normally. 

It’s usually caused by low blood oxygen levels. 

Hypoxia can also develop in parts of the body where blood supply is low from poor circulation.

Different tissues in the body respond to hypoxia in various ways. The cells and tissues in the body depend on continuous supplies of oxygen to perform the essential chemical processes that keep our bodies running smoothly.

When an essential oxygen supply is lacking on a continuous basis, many different psychological and physical problems can develop over time.
