ozone exposure increases antioxidant enzyme activity — SOD, catalase, and peroxidase — in lung tissue

SOD, catalase, and peroxidase are your body's built-in defense enzymes against oxidative stress — the kind that accumulates from pollution, poor sleep, and aging. When these enzymes become more active, your cells are better equipped to neutralize free radicals, which most people associate with faster recovery, reduced inflammation, and more sustained energy.
