If you have been short of breath and smoke?

Stop smoking. Smoking damages the lungs, making it harder to breathe.

Try relaxation techniques. This can help to slow down your breathing and reduce anxiety, which can also lead to shortness of breath.

Avoid things that trigger your shortness of breath. This can include certain foods, drinks, or activities.

Get regular exercise. Exercise can help to strengthen your lungs and make you more efficient at breathing.

See a doctor if your shortness of breath is severe or does not improve. There may be an underlying medical condition that needs to be treated.
