What causes lungs to become weak?

There are many causes to have weak lungs.

Some of these are when you are born immature and the lungs, being the last organs to develop, would be weak also.

* Cigarette smoking because of the nicotine that a smoker inhales. The nicotine travels and gets stuck in the lungs, occupying the spaces which are intended for the oxygen to be utilized by our body.

* Weak chest muscles or body muscles can make the lungs weak because if the respiratory muscles are affected then there will be difficulty inhaling oxygen.

* The last factor will be the underlying disease of the lungs. Once you are inflicted with a disease of the lungs it will never be 100% fully efficient anymore.

Protect your lungs by exercising daily, avoid smoking, and have a good sleep.
