The heart is overworked. High levels of smoking in the body result into increased heart rate. This increases the number of times the heart beats within a minute. This may cause the overstretching of the heart muscles as it tries to pump blood. As a result the heart may beat too fast. Smoking may also raise the cholesterol levels in the body. This goes and surrounds the muscles of the heart making it hard for the walls to pump blood. Such complications may affect the general performance of the body a great deal. Too much smoking leads to a lot of tar being inhaled into the body. This is a chemical component of cigarettes and other drugs that are consumed by smoking.
