According to NHS:
Why it should be done. Giving up smoking increases your chances of living a longer and healthier life. It instantly reduces your risk of death or serious illness due to smoking-related diseases, such as lung cancer, chronic obstructive pulmonary disease (COPD), and heart disease.
Health benefits from the moment you stop
When you stop smoking, the benefits to your health begin straight away. As your body starts to return to normal, you will start to feel healthier, and within a few weeks you will also start to notice the benefits. For example:
After one month – your skin will be clearer, brighter and more hydrated.
After 3-9 months – your breathing will have improved, and you will no longer have a cough or wheeze. Your lung function may have improved by up to 10%.
After one year – your risk of heart attack and heart disease will have fallen to about half that of a smoker.
After 10 years – your risk of lung cancer will have fallen by half.
After 15 years – your risk of heart attack and heart disease will be the same as someone who has never smoked.
Research into smoking shows that people who quit smoking before the age of 35 have a life expectancy only slightly less than people who have never smoked. Those who quit before they are 50 years of age reduce their risk of dying from a smoking-related disease by 50%.
As well as the immediate and long-term benefits to your health, there are many other good reasons to quit smoking, such as those outlined below.
No longer causing harm to others through passive smoking, particularly babies and children, who are at risk of sudden infant death syndrome (SIDS), asthma, and ear and chest infections.
It is less likely that your children will go on to smoke. Research shows that children living with parents who smoke are almost three times more likely to start smoking themselves.
Limiting harm to your unborn baby. Although smoking at any stage of pregnancy can harm your baby, most of the harmful effects of smoking occur in the second trimester (weeks 14-26) and third trimester (week 27-birth). Therefore, if a woman quits smoking during her first three months of pregnancy, she will have a similar risk of giving birth to a low weight baby as a non-smoker.
