Smoking is harmful to almost every part of your body and increases the risk of many diseases. Within 10 seconds of your first puff, the chemicals in tobacco smoke reach the brain, heart, and other organs. These toxins go where the blood flows, causing damage on their way.
There are many smoke-related concerns for individuals. Tobacco smoke contains over 7,000 chemicals, with at least 250 of those being harmful, including carcinogens. These are toxic and create havoc on the body, leading to various diseases and conditions.
Harmful Effects of Smoking on the Lungs
Smoking causes lung damage. The tissue loss that occurs is never retrieved. The damage makes you more susceptible to certain infections and lung disease.
Smoking is the leading cause of lung cancer, accounting for nearly 85% of cases. This is due to the presence of tobacco smoke in the cells lining the lungs, damaging them and allowing for abnormal cell growth, resulting in cancerous tumors.
Harmful Effects of Smoking on Cardiovascular Health
Smoking increases the risk of cardiovascular diseases like heart disease, stroke, and heart attack. The chemical in tobacco smoke damages the blood vessels, leading to buildup of plaque and narrowing of arteries, constricting the blood flow to organs.
Harmful Effects of Smoking on Respiratory Health
Another consequence of smoking is damaged airways, causing chronic obstructive pulmonary disease (COPD), including chronic bronchitis. Inhaling the smoke irritates and inflames the airways, causing long-term damage to lung tissue. This impairs the respiratory function.
Harmful Effects of Smoking on Vision
The long-term effects of smoking can also affect the vision. It can affect the optic nerve and lead to the development of certain conditions. These can include glaucoma, in which the pressure in the eye increases, putting pressure on the optic nerve, causing loss of sight. Furthermore, cloudy vision and age-related macular degeneration are other risks in people who smoke.
