“Now that I'm older, quitting smoking won't make a difference,” is a belief found among many smokers. However, recent scientific research has debunked this misconception. Studies have shown that quitting smoking even after the age of 40 or 45 leads to significant improvements in brain function. A study published in an international health journal examined thousands of people over the age of 40. This included both groups who had quit smoking and those who were still smoking. Various tests on memory, thinking ability, and language control revealed that those who had quit smoking had better brain capacity.
How does smoking harm the brain?
The harmful chemicals in cigarettes damage the blood vessels that supply blood to the brain. This increases oxidative stress in the body and gradually weakens brain cells. As a result, problems such as memory loss, lack of concentration, and slowed thinking speed arise. If this condition persists for a long time, the risk of dementia can increase.
Serious diseases increased by smoking
The smoke from cigarettes mixes with the blood from the lungs and spreads throughout the body. This increases the risk of heart disease, stroke, COPD, diabetes, as well as lung cancer and many other types of cancer. Additionally, smoking increases the risk of reduced vision, respiratory disorders, and premature death.
What changes occur in the body after quitting smoking?
The healing process in the body begins immediately after stopping smoking. Within a few weeks, circulation improves, breathing becomes easier, and fatigue decreases. In a few months, the lungs start to clean themselves, and the person begins to feel more energetic. Most importantly, there is a gradual improvement in brain function.
It's never too late to quit smoking
Research has shown that quitting smoking at any age has positive effects on the body. The thought of “it's too late now” becomes the biggest obstacle. With the right decision and strong willpower, it is possible to quit the habit of smoking.
