13 Unexpected Things That Harm Your Brain
Just like the other organs of our body, our brain can suffer from various factors, even those that aren’t too obvious.
Bright Side will tell you about everyday habits that can cause significant harm to your brain. And those who read the article to the end are in for an unexpected quote from a clever man.
13. Lack of communication
A study conducted at the University of Michigan showed that even 10 minutes of communication per day increases mental ability. It is not at all necessary to go out and talk to the first person you see — talking with a friend or relative on the phone also stimulates the brain.
12. Too much sugar
According to research, a large amount of sugar adversely affects the neurotrophic factor of the brain, or BDNF, which is responsible for the production of neurons. In particular, BDNF is very important for the formation of long-term memory and learning.
11. Lack of brain exercise
According to scientists, the peak of brain productivity is reached at 16-25 years, after which it slowly declines. However, extensive research has shown that regular brain exercise (reading, solving puzzles) can significantly improve its performance, even in people who have the first signs of senile dementia.
10. Skipping breakfast
Studies show that children who eat breakfast regularly perform much better at school, especially in the sciences. Skipping breakfast causes a decrease in blood glucose levels, which, in turn, negatively affects brain functioning.
9. Junk food
Too much fast food in the diet and constant overeating negatively affect connections between brain cells and, as a result, the training and formation of short-term and long-term memory. In addition, eating too much fast food may cause depression.
8. Ice cream
Any cold food, including ice cream, can cause a sudden headache. It is believed that cold food narrows the blood vessels. The body, trying to prevent hypothermia, sends warm blood to the brain, which, in turn, dilates the blood vessels. It is this difference, according to scientists, that causes a headache.
7. Cell phones
A study on rats revealed a link between brain cancer and the use of cell phones. However, you should not throw out your smartphone. Instead, doctors advise you to use a speaker or a headset for talking and to not put the phone near your pillow while you sleep.
6. Covering your head during sleep
When we sleep covering our head with a blanket, we reduce the amount of oxygen entering our body because, in this case, we have to breathe in already "recycled" air, which is saturated with carbon dioxide. This creates a lack of oxygen for our brain.
As you know, the human brain is 70-80% water. In addition, water is responsible for the delivery of necessary substances to the brain. The brain works most effectively when it does not lack H2O.
According to researchers, alcohol consumption destroys connections between brain cells. However, there is good news: for those who stop drinking alcohol, the brain eventually returns to normal.
As research has shown, smoking leads not only to cancer but also to a decrease in the thickness of the cerebral cortex. Such damage can significantly affect mental abilities because it is this part of the brain that, among other things, is responsible for thinking.
2. Lack of exercise
1. A strict diet
It turns out that during a strict diet, it’s not only the body that’s losing weight. Research has shown that a severe restriction in nutrition causes the brain to actually eat itself. This is another reason to be more reasonable in approaching your own diet. Don’t exhaust yourself with "hungry" diets — just eat right.
Hint: This man’s brain weighed only 1,230 grams (2.7 lb), which is about 10% less than the brain of an average male, whose weight is approximately 1,400 grams (3 lb).
