Smoking is one of the largest contributing factors to heart and circulatory diseases. Smoking is not just bad for you, but it’s also for the people around you. Breathing in second-hand smoke can increase the chances of getting cancers or other respiratory problems.
Every cigarette contains approximately 4,000 chemicals and many of these chemicals are harmful to your health. Chemicals like carbon monoxide, nicotine and tar are poisonous to your body. Here are some of the harmful effects smoking can have on your heart health.
Harmful Effects of Smoking
Reduces Blood Oxygen Levels
Smoking contains chemicals like Carbon monoxide, a poisonous gas that reduces your blood oxygen levels, this condition is called Hypoxemia. In mild cases, Hypoxemia causes headaches and shortness of breath, but in more severe cases, it can cause problems with brain function and the cardiovascular system.
Increases Risk of Cancer
Cigarettes contain tar, a toxic chemical that creates a sticky brown layer around your lungs. When you smoke a cigarette around ⅔ of the tar stays back in your lungs and over time the deposit of this sticky brown residue can lead to Cancer. Tar coats the alveoli, the part of the lungs that absorb the oxygen you breathe, and makes it difficult for gas exchange to take place.
Increases Heart Rate and Blood Pressure
Nicotine is the addictive chemical found in cigarettes, it causes your blood pressure and heart rate to elevate. Nicotine also contributes to the hardening of the arterial walls which can cause a heart attack.
All these chemicals in cigarettes cause fatty deposits on the walls of your arteries, making it difficult for oxygen-rich blood to reach all parts of your body. Blockages in your arteries can cause a stroke or a heart attack. But don’t worry, it’s never too late to quit. Here is how your body starts to repair itself once you quit smoking.
