Detailed explanation-1: -Smoking affects many aspects of your body, including your physical endurance. If you smoke, you get less oxygen in your heart, lungs and muscles. This reduces your physical fitness. It can also cause inflammation in your bones and joints that may contribute to other conditions like osteoporosis.
Detailed explanation-2: -Smoking increases the formation of plaque in blood vessels. Coronary Heart Diseaseoccurs when arteries that carry blood to the heart muscle are narrowed by plaque or blocked by clots. Chemicals in cigarette smoke cause the blood to thicken and form clots inside veins and arteries.
Detailed explanation-3: -The nicotine and carbon monoxide from smoking may make your blood “sticky” and your arteries may become narrow. Narrow arteries reduce the flow of blood to your heart, muscles, and other body organs, making exercise harder.
