Your risk of having a heart attack goes down
Dr. Sanjay Sethi, professor and chief of the University of Buffalo’s Division of Pulmonary, Critical Care and Sleep Medicine, told INSIDER that the cardiac benefits begin right away.
“Smoking has a lot of adverse effects on the body. In terms of some of the risks, heart attacks, and cardiac complications of smoking, those go down soon after quitting. Some of them start right away because the oxygen delivery gets better and the inflammation in your body goes down,” said Sethi, who is also the assistant vice president for Health Sciences in the Department of Medicine at the Jacobs School of Medicine & Biomedical Sciences at the University of Buffalo. “The cardiac side effects will decline quite rapidly.”
