What are the benefits of quitting smoking for my heart?


Within 6 hours of quitting smoking, blood pressure improves and the heart rate slows.

After a year, a former smoker’s risk of heart attack or stroke reduces by half. This risk continues to reduce over time and, after 15 years, the risk is the same as someone who never smoked.

That’s quite inspiring. But there’s more. Quitting smoking has many other health benefits including:

  • A stronger immune system
  • Increased levels of protective antioxidants in the blood
  • Improved blood circulation to the hands and feet
  • Reduced stress.
