Only one cigarette the day already puts at great risk the heart of smokersaccording to a study by British researchers. "There is no safe level of smoking for cardiovascular disease," the researchers wrote in a study published in the British Medical Journal.
"Smoking one cigarette a day carries a risk of developing coronary heart disease and stroke much larger than expected, about half the risk for those who smoke 20 a day, "the study said.
Difference between men and women
The projection is worse for women, since it increases the risk of cardiovascular disease in 57% for those who smoke a daily cigarette, while in men the danger increases by 48%.
"Smokers should try to stop smoking rather than reduce" cigarette smoking, the researchers said.
The study is a meta-analysis of other 55 studies published between 1946 and 2015and incorporates the data of several million people.
About lung cancer, other studies show that "smokers who reduce the number of cigars may benefit from a significant reduction in the risk of developing cancer", the authors of this research recalled.
