Quitting smoking is one of the best things that can be done for heart health — and the good news is that the benefits start sooner than most people expect!

Here's a general timeline of what happens after quitting:

- Within 20 minutes: Heart rate and blood pressure begin to drop
- Within 12 hours: Carbon monoxide levels in the blood normalize
- Within a few weeks: Circulation improves and the heart starts working more efficiently
- After 1 year: The risk of heart disease drops by 50 percent compared to someone still smoking
- Over time: Risks of artery hardening and smoking-related blood clots continue to decrease

The benefits keep building the longer smoking stays in the past. Every single day without cigarettes is a meaningful step forward for heart health. Cravings and withdrawal symptoms like irritability or tiredness are completely normal at first — but they do fade. Some helpful strategies include:

- Nicotine replacement options like patches or gum
- Avoiding triggers that make the urge to smoke stronger
- Finding healthy distractions like walking or chatting with a friend
- Leaning on loved ones for support

As one MyHeartDiseaseTeam member shared, "I quit smoking cold turkey last month, and just wish I did it sooner." Talking to a doctor can also open doors to additional support and resources.
