Oxidative stress is an imbalance between the production of free radicals (highly unstable molecules that are naturally formed when you exercise and when your body converts food into energy) and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants.

Some ways our bodies can be exposed to oxidative stress are by having an unbalanced diet, smoking, or sun exposure. Some ways to prevent oxidative stress are having a healthy diet, not smoking, exercising regularly and wearing sunscreen.
