Exercise is needed for the lungs to function at peak performance and since “lung function declines gradually every year starting at age 35,” Rozo said, it’s important to incorporate habits that help increase our lung capacity.
This includes daily aerobic workouts and doing breath work like diaphragmatic breathing. Lie down on your back, placing one hand on your stomach over your belly button and one on your chest. Inhale through your nose for two seconds, feeling the air go into your abdomen and your stomach pushing out. Then breathe out for two seconds through pursed lips, allowing your stomach to deflate. Repeat several times.
