Reducing your daily cigarette habit may not be enough to offset its devastating effects on your heart health. Researchers have found that even smoking just a few cigarettes a day significantly increases your risk of developing heart disease, with those who quit late in life still facing a higher mortality rate than non-smokers.
According to the latest study published in PLOS Medicine, individuals who smoke two to five cigarettes per day are twice as likely to develop heart disease compared to people who have never smoked at all. Those who reduce their daily cigarette intake to just five or fewer cigarettes per day, however, face a staggering 60% higher risk of dying from any cause than those who have never lit up.
In fact, it may take as long as 30 years for your body to fully recover from the damage caused by even occasional tobacco use. This is according to Dr. Michael Blaha, one of the lead investigators on the study and an expert with the American Heart Association's Tobacco Center for Regulatory Science.
The findings come at a time when cigarette use is declining in the US, but unfortunately, smoking remains the leading cause of preventable death and disease nationwide. As Dr. Blaha pointed out, "we were surprised by the strength of harm from even a low quantity of cigarettes, and the incredible importance that quitting early had on long-term heart health."
The study analyzed data from over 320,000 adults in the US who participated in previous studies spanning 20 years or more. Researchers looked at the impact of smoking duration and cessation on risks for various cardiovascular conditions, as well as all-cause mortality.
Interestingly, those who smoke 11 to 15 cigarettes per day β a relatively small pack (less than a standard pack of 20) β are still at an 84% higher risk of heart disease and twice the risk of death from any cause.
