1. Sedentary Lifestyle.
There have been studies that have shown that a sedentary lifestyle changes the shape of certain neurons in the brain, and this indicates a link between inactivity and cognitive impairment.

2. information overload.
It is believed that the enormous amount of information we regularly receive from the Internet, television and other sources can cause fatigue and stress, which leads to overload.

3. wearing headphones.
If you constantly listen to loud music, your brain can't fully perceive your surroundings and important sounds like speech, and can't retain what you hear in your memory. This and other factors lead to cognitive impairment.

4. Poor quality of sleep.
This leads to slower reactions, impaired memory, memory and mood functions, and headaches. What's more, studies show that lack of sleep can even reduce brain mass.

5. Negative thinking.
Negative thinking is adjacent to anxiety, anger and emotional overload. If you experience these emotions briefly, there's nothing wrong with that. But when you are under the constant influence of negativity, it impairs blood flow to the brain due to damage to the blood vessels by stress hormones.
