what is oxidative stress

What causes oxidative stress.
As you breath in and out, your body reacts with oxygen which is used by the body cells to produce energy. As a result of this activity free radicals(reactive molecules) are produced within the body cells causing oxidative stress. If the body’s anti-oxidant(which is protein controlled) response does not manage to keep up with the oxidative stress then oxidative damage occurs. Therefore, oxidative stress can be explained to be caused by the imbalance between reactive oxygen species and inadequate antioxidant defense method. oxidativestressfree.org/
