Every year, more than five million people worldwide die from smoking-related causes, according to a recent Harvard study. Health experts say the damage smoking does is almost immediate.
Cotton-O'Neil nurse Cindy Baird says within five minutes of smoking a cigarette, the heart rate increases. Keep smoking, and she says it gets worse.
Baird says smoking increases the expansion of the air sacs where the air exchange happens and makes them less pliable, so air is not exchanged efficiently. Over time, she says, they fill with sludge and become stiff and immobile.
For you, that means, you're not able to tolerate activity and your fingers and toes feel cooler because of damage to your blood vessels.
But here's the good news.
"The body has an incredible capacity to heal itself," Baird said.
She says within 20 minutes of quitting smoking, the heart rate drops to normal and the pulse rate is normal. Within eight hours, smoker's breath disappears and carbon monoxide levels in the blood drop. Within 24 hours, your heart attack risk begins to decrease; and in three days, breathing is easier. Stick with it, and within two years, your heart attack risk drops to near normal.
The impact was recently shown in a study by Johns Hopkins University. It found that participating in quit-smoking programs can prevent about two smoking-related deaths each year for every 1000 people in the program.
Baird admits most people will have to try more than once to quit. But once you do, she says, your body will thank you.
