WHY IS IT HARD FOR YOU TO BREATH WHEN YOU RUN AND DO HEAVY ACTIVITIES?

Breathing difficulties during running or heavy activities can be attributed to several factors, including increased oxygen demand from your muscles and possible limitations in lung capacity or efficiency. If you're not conditioned for such activities, your respiratory muscles may struggle to keep up, leading to sensations of breathlessness. Additionally, factors like poor air quality, Allergies, or underlying health issues can further exacerbate the challenge of breathing during exertion.
