Stopping smoking lets you breathe more easily
People breathe more easily and cough less when they give up smoking because their lung capacity improves by up to 10% within nine months.
In your 20s and 30s, the effect of smoking on your lung capacity may not be noticeable until you go for a run, but lung capacity naturally diminishes with age.
In later years, having maximum lung capacity can mean the difference between having an active, healthy old age and wheezing when you go for a walk or climb the stairs.
