This Is Why Smoking Makes It Harder to Heal

Smoking is a bad habit. We all know that. But did you know that it also makes wounds harder to heal? 

SciShow explains the whys in this video. It turns out that there are many different mechanisms behind this.

"If a doctor has told you to quit smoking, that's not just because they're worried about lung cancer. Those cigarettes are messing up your body's natural healing process in more ways than one," reads the video's description.

There are four main phases of wound healing and smoking actually messes with all of these stages. Smoking can also make it easier for clots to form and is responsible for other nefarious wound-related effects.

Worse of all, even if you stop smoking during a wounded period, your body will still not heal as well as a non-smoker. As such, it is best to quit as early as possible.

We won't give you more details. You have to watch the video for that. But if you have been thinking of quitting, this video will do the trick.
