Understanding Oxidative Stress. Like an apple turns brown when exposed to air, our cells can ârustâ when we breathe due to oxidative stress, a process caused by free radicals. Free radicals are unstable molecules that damage or âoxidizeâ cells throughout the body in a process called oxidative stress.
The major causes of stress are: 1  Toxic stress:A constant need for cellular detoxification from chemical exposure. 2  Emotional stress requiring the production of adrenaline and andrenal hormones. 3  Physical trauma that reduces circulation and O2 supply. 4  Infections that use up O2 to combat bacteria, fungi and viruses.
