After quitting smoking, lung energy can generally be gradually restored, but it can not be completely restored to the normal level of never smokers. Quitting smoking is very helpful to some patients with lung disease. Usually, chronic inflammation of lung tissue and bronchial and tracheal walls is closely related to smoking. Smoking may lead to the changes of some enzymes in the body, and the increase of oxygen free radicals will cause damage to lung tissue. Therefore, if possible, try not to smoke, so as not to do harm to your body.
In addition, we should develop good living habits in daily life, pay more attention to rest, don't stay up late, don't eat some spicy and irritating foods, and eat more foods rich in protein and vitamins to enhance our own resistance.
