Smoking - why quitting makes you 'younger'

Updated: Jan 24

Quitting smoking is the single best thing your can do to improve your health and get yourself 'younger'. The benefits start within minutes and increase day after day for years. Here's how:

Within 20 minutes

... your blood pressure and pulse rate go back to normal levels.

Within 24 hours

...all the carbon monoxide has now gone. This means more oxygen can be carried round your body, enabling your lungs to start clearing out the mucus and other smoking debris.

Within 48 hours

...there is now no longer any nicotine in your body – and your sense of taste and smell starts to improve.

Within 72 hours

...breathing becomes easier as bronchial tubes begin to relax and you’ll see energy levels increase, too.

Within 2 to 12 weeks

...your blood circulation will improve.

Within 3 to 9 months

...your lung function increases by up to 10% and you’ll notice less coughing, wheezing and breathing problems.

Within 1 year

...your chances of developing heart disease falls to the same level as a non-smoker.

Within 10 years

...your chances of developing lung cancer reduces to half the risk of a smoker.
