<p data-start="3423" data-end="4237">As someone who works in an office for 10+ hours a day, the controlled indoor environment has always triggered mild breathing discomfort&mdash;especially during seasons when ventilation systems run continuously. Asthafen 1 mg has been a reliable daily solution for me. It helps lower the sensitivity my airway usually has toward recycled air, slight dryness, and even dust movement. One thing worth noting: Asthafen 1 mg seems to work best when taken consistently, allowing it to support the airway over time rather than reacting to one-off irritants. It makes the workday feel much smoother because my breathing stays more stable, even if the indoor environment isn&rsquo;t ideal. I&rsquo;d recommend it to anyone feeling daily breathing discomfort specifically tied to indoor air quality or long hours in climate-controlled spaces.
