After quitting smoking for just 20 minutes, a smoker’s heart rate and blood pressure will return to normal. In just one year, the risk of coronary heart disease is reduced by half compared to still smoking. Dr. Mai Manh Tam from the Department of Respiratory Medicine at Tam Anh General Hospital in Hanoi explained that smoking is the leading cause of lung cancer and respiratory diseases such as COPD and pulmonary fibrosis.
Nicotine in cigarettes stimulates the production of adrenaline, causing the heart rate to increase and blood pressure to rise. Carbon monoxide in cigarette smoke reduces the amount of oxygen transported by red blood cells, leading to fatigue and weakness. After 12 hours of not smoking, carbon monoxide levels return to normal. Smokers often experience coughing and increased phlegm production, which improves after quitting smoking for 1-9 months.
Quitting smoking reduces the risk of various cancers, especially lung cancer, and improves overall health. The risk of coronary heart disease is significantly reduced after quitting smoking for a year, as the progression of arteriosclerosis caused by CO exposure decreases. The risk of heart attack and coronary artery disease is also reduced over time, with the risk returning to that of a non-smoker after 15 years of quitting.
Despite the benefits of quitting smoking, many find it difficult due to nicotine cravings and withdrawal symptoms. Doctors can prescribe medication to help with quitting, and it’s important for family, friends, and colleagues to provide support and encouragement. Understanding the long-term health benefits of quitting smoking can motivate individuals to stay committed to quitting.
In conclusion, quitting smoking has numerous long-term health benefits that are worth considering before continuing on this harmful habit. From reducing cardiovascular risks to improving overall health, there are countless reasons why everyone should quit smoking today.
