Description
Jessica L. Fernandes and co-authors explore, in a 2026 study, how anxiety disorders pair with body chemistry during the pandemic years. More than 300 million people live with an anxiety disorder, and oxidative stress may play a part. Oxidative stress means harm from reactive molecules outruns the body's defenses. The team compared 116 adults with an anxiety diagnosis against 234 adults without one, recruited in Brazil between September 2020 and July 2021.
Standard scales scored anxiety, low mood, stress, daily rhythms, thinking, and day-to-day function. The anxiety group fared worse on all of them, with more stress and more broken daily rhythms. Blood tests showed lower total antioxidant capacity in the anxiety group at first pass. Once the team corrected for the many tests run, that blood gap no longer held up. The authors keep oxidation as a thread worth more study, while the mood and rhythm findings stand on firmer ground.
