2. Excessive smoking causes the brain to weaken and shrink. It also results in adult cognitive decline and persists for many years together, even if one stops smoking. This is the reason smokers are at a higher risk of developing dementia as well as Alzheimer s disease by at least 79%. Smokers often experience insomnia and sleep apnea, which could up the risk of dementi a in later years.

3. Smoking frequently also affects your Intelligence Quotient (IQ). Oxygen supply to the brain is reduced and carbon dioxide presence increases, affecting your haemoglobin. The capability to analyse problems and solve matters in the workplace is often affected due to chronic smoking habits.

4. The common notion that smoking allows one to focus is just a myth. Instead, it is exactly the opposite. Smoking reduces your ability to concentrate efficiently. Fatigue often kicks in due to the lack of oxygen supply to the brain.

5. Chronic smokers are at a high risk of a brain stroke. Nicotine presence in the blood makes the blood thicker. There is an increased risk of plaque deposition in the arteries, caused due to smoking. This thus compromises the blood supply to the brain which causes a brain stroke. The risk of dying from a stroke is double in smokers, as compared to non-smokers. However, if one stops smoking within five years, with sufficient nutritional intake, the risk can be reduced to the same of a lifetime non-smoker. If you have survived a stroke, you can be left with permanent damage after having a stroke. Also read Quit smoking: What happens a day, week, month and year after you do it.
