Doctor Explains What Changes in the Body When You Quit Smoking

Doctor Ana Pérez analyzes the changes that occur in the body when someone quits smoking, emphasizing that the benefits are immediate and not just long-term. Within 20 minutes of the last cigarette, heart rate and blood pressure begin to decrease, while carbon monoxide levels in the blood decrease and oxygen levels increase within 8-12 hours. According to the doctor, the risk of heart attack decreases within 24 hours, and nerve endings begin to recover after 48 hours, resulting in the restoration of smell and taste. After a month, cough and shortness of breath decrease as the lungs clear, while energy and physical condition improve. In the long term, quitting smoking improves skin elasticity, reduces oral health problems, and improves sleep quality. After one year, the risk of heart attack is reduced by 50%, and after five years, the risk of cancer is significantly reduced. The doctor emphasizes that quitting smoking is one of the most important decisions someone can make for their health, with immediate and long-term benefits.
