Practical Tips to Clear Brain Fog

5. Smokers face higher risks

Some people may believe that smoking a cigarette or two improves their ability to concentrate but today's medical knowledge shows that the opposite is true; studies show that heavy smokers are more likely to suffer from brain fog. One of the reasons why they are so susceptible is that smoking reduces the amount of oxygen reaching the brain. It also shrinks the cortex that surrounds the brain. If you never heard doctors make this point, it is probably because there are many more major health risks associated with smoking and they want to stress these as opposed to some of its minor side effects.
