Quitting smoking is a challenge, with many smokers considering it to be one of the most difficult things to do. The effects of smoking are well-known – from a persistent cough to feeling breathless, fatigued, and overall unwell. Despite this, it is possible to quit, and many people take the first step towards a smoke-free life annually through campaigns like the Department of Health and Social Care’s Stoptober.
When you decide to quit smoking, your body undergoes immediate changes. One notable benefit is the reduced risk of developing cancer in the long term. However, there are also more subtle changes that occur almost instantly. Here are eight things that happen to your body as soon as you quit smoking:
After 20 minutes: Your pulse rate begins to return to normal.
After eight hours: Oxygen levels in your body start to recover, and carbon monoxide levels in your blood decrease by half.
After 48 hours: All the carbon monoxide in your body is flushed out, leading to improved lung function and enhanced taste and smell senses.
After 72 hours: Increased energy levels as your bronchial tubes relax, making breathing easier.
After 2-12 weeks: Improved blood circulation with more efficient oxygen supply to your heart and muscles.
After 3-9 months: Lung function increases by 10%, and respiratory issues such as coughing and wheezing start to improve.
After 1 year: A 50% reduced risk of a heart attack compared to a smoker.
After 10 years: A 50% reduced risk of dying from lung cancer compared to a smoker.
