Oxidative stress response

Oxidative stress response is the body's way of protecting itself from damage caused by harmful molecules called free radicals. These free radicals are generated during normal processes like energy production in cells or from external sources like pollution and smoking. When there are too many free radicals, they can harm cells, DNA, and tissues. The body responds by activating antioxidants—special molecules that neutralize free radicals and reduce damage. This response helps maintain cellular health and prevents diseases related to oxidative damage, such as aging, cancer, and heart issues.
