Oxidative stress is an imbalance between free radicals and antioxidants. Free radicals are molecules that contain oxygen with an uneven number of electrons. Antioxidants are responsible for giving the free radical an electron to stabilize it and make it become less reactive. Our bodies can be exposed to oxidative stress through radiation from the ultraviolet light. It can be exposed through cigarette smoke. As well as being exposed through pollution in the air and water.

Oxidative stress is an imbalance between free radicals and antioxidants in your body. Free radicals are oxygen-containing molecules with an uneven number of electrons. The uneven number allows them to easily react with other molecules. Free radicals can cause large chain chemical reactions in your body because they react so easily with other molecules. These reactions are called oxidation. They can be beneficial or harmful.

Antioxidants are molecules that can donate an electron to a free radical without making themselves unstable. This causes the free radical to stabilize and become less reactive.
