Give up smoking
Dr. Doug Wright, Medical Director, Aviva UK Health
Stopping smoking is good for your health, and some of those good effects start much sooner than you might think. Just 20 minutes after your last cigarette, your blood pressure and your heart rate return to normal.
8 hours after your last cigarette, nicotine and carbon monoxide levels reduce by half and oxygen levels return to normal. 24 hours after stopping smoking, carbon monoxide will be eliminated from your body a completely and your lungs will start to clear out mucus and other smoking debirs.
48 hours after giving up smoking, there’s no nicotine left in the body at all and your ability to taste and smell will improve greatly. 72 hours after stopping smoking, your breathing should become easier, your airways begin to relax and your energy levels increase.
Between 2 and 12 weeks after stopping smoking, your circulation will improve. 2 to 9 months after giving smoking, you should find that coughing, wheezing and breathing problems improve as your lung function will have increased by up to 10%. One year after giving up smoking, you will have halved the risk of stroke.
