Deep breathing is really good to improve lungs health as it fills with more oxygen into the lungs. Deep breathing exercises can benefit the lungs by increasing lung capacity, improving oxygen exchange, and promoting relaxation. By inhaling deeply, more oxygen enters the bloodstream, which can enhance overall lung function. Deep breathing can also help clear out toxins and stale air from the lungs, reducing the risk of respiratory infections and supporting respiratory health. Regular practice of deep breathing can strengthen respiratory muscles and improve lung efficiency.
