Seheult: moderate exercise (150 minutes/week) reduces infection risk by 40-50%. The mechanism: exercise mobilizes immune cells, improves circulation, reduces chronic inflammation, and enhances vaccine responses.

Seheult: nasal breathing filters, warms, and humidifies air. It also produces nitric oxide, which kills pathogens and dilates airways. Mouth breathing bypasses all of these defenses and is associated with worse immune outcomes.
