After you stop smoking beneficial changes take place almost immediately:
Your blood pressure and pulse rate return to normal. The temperature of your hands and feet normalize.
The carbon monoxide level in your blood is reduced by half. Oxygen levels return to normal.
Carbon monoxide will be eliminated from the body. Lungs start to clear our mucus and other smoking debris. Your likelihood of having a heart attack decreases.
Ability to taste and smell is greatly improved. Nerve endings start to grow.
Breathing becomes easier. Bronchial tubes begin to relax and energy levels increase. In 72 hours nicotine is out of your system.
Circulation improves. It becomes easier to walk.
Coughs, wheezing, sinus congestion and breathing problems improve as lung function is increased by up to 10 percent. You have more energy.
Risk of a heart attack falls to about half of that of a smoker.
Risk of lung cancer falls to half that of a smoker. Pre-cancerous cells have been replaced.
Risk of heart attack falls to the same as someone who has never smoked
