Stress can impact sleep, focus and more—down to our molecules. Oxidative stress results from an imbalance of oxidants and antioxidants, caused by an increase of free radicals, or reactive oxygen species, that can damage cells and their components. Observed in several diseases, from Parkinson’s disease to hepatitis to cancer, chronic oxidative stress also appears to cause hypoxia, another kind of stress condition involving insufficient oxygen in tissues. But it’s not well understood how stress impacts biological processes at the molecular level.
