The Dark Side of Oxygen

We depend on oxygen for life. But in fact, oxygen is corrosive: ageing us, damaging cell DNA, and 'rusting' us from the inside.

Biology - Human Body - Learning Points.

Oxygen is vital in powering every cell and process in the human body.

90% of the body's energy is produced by mitochondria, which live in every cell and harness the power of oxygen.

Oxygen is corrosive and degrades into reactive particles called free radicals.

Free radicals age the body and skin, causing wrinkles, and can damage DNA in cells, which can lead to cancer.
