Q I would like to ask how smoking effects heart ?
Smoking affects the heart negatively, the chemicals carbon monoxide and nicotine present in cigarettes are responsible for it. Carbon monoxide attaches to the hemoglobin of the blood. Hemoglobin is responsible for the transport of oxygen throughout the body. Carbon monoxide replaces the oxygen, thus reducing the ability of hemoglobin to transport oxygen to the heart and throughout the rest of the body. Nicotine stimulates adrenaline production, which causes the heart to beat faster and thus raises blood pressure. Smoking also negatively affects the heart by its impact on the production of cholesterol. Cigarette smoke increases the production of LDL cholesterol (the bad cholesterol) while at the same time decreasing the production of HDL (the good cholesterol).One Cigarette will, of course, not lead to heart problems, but long-term smoking or even long-term exposure to tobacco smoke can have serious consequences to the heart. High blood pressure causes the heart to work harder on a daily basis, which means a strain on the heart that builds up over the years. Cigaratte smoke constricts the blood vessels and reduces supply to heart.
