Did you know that some of the things you could be doing daily have a damaging effect on your brain? You might be surprised to learn that certain habits and lifestyle choices ruin your cognitive performance.
Top 10 Things That Have a Damaging Effect on the Brain
1. Not getting enough sleep
This habit is familiar to anyone and is becoming a global problem. According to studies, more and more people experience sleep disturbances.
A severe lack of sleep creates the risk that different parts of the brain move into a phase of slow-wave sleep while being in a state of wakefulness. As a result, a person can’t concentrate and their fine motor skills deteriorate. Regular sleep deprivation leads to brain cell death.
2. Skipping breakfast
Skipping the morning meal affects your performance and energy during the day. It seems obvious, but the point here is not so much the consumption of energy necessary for the body, but the fact that when you skip your breakfast, this lowers the level of sugar in your blood. This in turn reduces and hinders the flow of nutrients to your brain.
The preceding point explains why it is necessary to maintain an adequate level of blood sugar. However, it doesn’t mean that you should eat sweets to have a good brain performance.
In fact, excessive amounts of sugar cause problems with digesting proteins and nutrients. It leads to the same result as the low level of blood sugar: your brain does not receive enough nutrients.
Severe emotional stress weakens the connections between neurons and thus complicates the understanding of cause-effect relationships and sequence of events. Stress leads to poor memory, anxiety, and the feeling that everything goes wrong.
5. Tranquillizers and sleeping pills
The use of sleeping pills and popular tranquilizers such as Xanax can impair your memory and possibly lead to amnesia, dementia, and obsessive suicidal thoughts.
Speaking about the negative effects of smoking on the body, the image of black lungs and damaged teeth probably comes to your mind. At the same time, it is not said much about the damaging effect on cigarettes on the brain: nicotine narrows its blood vessels. Besides the problems associated with a lack of nutrients in the brain, this greatly increases the risk of Alzheimer’s disease.
7. A lack of sunlight
A lack of sufficient sunlight directly affects your cognitive abilities. First, ultraviolet light produced by sunlight regulates your blood circulation, that is, the flow of oxygen and nutrients. Second, sunlight helps produce serotonin – the neurotransmitter that affects your mood.
8. Not enough water
Too low water consumption has a damaging effect on the brain since it causes a decrease in brain volume. This considerably reduces its efficiency and leads to almost zero ability to memorize information. It is recommended to drink an average of 1,5-2 liters of water per day.
9. Too much information
Year after year, the amount of information we digest increases enormously. This would seem quite useful for training your brain and keeping it in shape. However, the brain responds to such an information overload with resistance. It happens because when there is too much information, at a certain point, it is no longer absorbed, which causes memory lapses.
Here is another unfortunate consequence of the digital world we live in: people need to simultaneously process multiple streams of information. As a result, none of it is absorbed properly, and our brains get used to this way of working.
We perceive all the information at a superficial level. At the same time, we find it more and more difficult to stay focused on doing only one thing without frequent changes in activity.
