Tells what habits ruin the human brain and interfere with its work.

Alcohol consumption. The habit of drinking alcoholic beverages harms the thought process of the brain, stopping it. Ethanol contained in alcohol has the property of a solvent; it and its products manage to penetrate nerve cells, destroying them and reducing the sensitivity of neurotransmitters and receptor activity.

Ethanol does indeed kill brain cells. Thus, a person becomes more inhibited, and intellectual abilities are greatly reduced. There is a scientifically substantiated opinion that together with urine after alcohol, a person removes dead brain cells from the body.


The use of narcotic substances. The habit of using illegal drugs destroys the brain. Psychotropic drugs provoke the death of brain cells. Drugs lead to toxic encephalopathy. In this case, there is a violation of intellectual activity, coordination, reflexes, speech pathologies, the occurrence of paralysis.

Busy with harsh and toxic odors. Passion for aromatherapy can lead to headaches or discomfort. This is due to the specificity of smells and our receptors. Receptors transmit information about aromas in the form of electrical impulses to the brain, impulses go along the olfactory nerve, individual fibers of which lead to the hypothalamus and amygdala.

The hypothalamus is called the “animal brain”, which is responsible for our behavior related to self-preservation, hunger, thirst, mate selection and raising offspring. It is he who produces oxytocin – the hormone of joy and trust. And if the smell is chosen incorrectly or exceeded in dosage, then the brain has the wrong associations that give alarm signals to the body. As a result, instead of relaxing, a person gets health problems in the form of headaches or an allergic reaction.

Smoking. Nicotine and other toxic substances in tobacco smoke adversely affect the brain. Under the influence of nicotine, its blood supply is disturbed. At smokers attention, memory, abilities to logic worsen and coordination of movements is broken. In addition, smokers are more likely to overwork, worse endure normal stress. Long-term smokers often have higher levels of anxiety and an increased likelihood of developing depression.

Lack of sleep. The habit of not going to bed on time, snatches of sleep, or systematic lack of sleep reduces brain performance and leads to a loss in the quality of perception of new information. Lack of sleep significantly inhibits the reaction to external stimuli, which carries a dangerous tendency to lose sight of what is important, and a decrease in concentration can lead to a danger to life in general.

For example, sleepy drivers are much more likely to get into an accident than those who sleep fully. In sports, it can be injuries and low performance of an athlete.

The use of psychostimulants. Energy drinks and caffeine. Substances that seem to increase the level of performance, on the contrary, significantly reduce performance after the end of exposure. Caffeine blocks adenosine, a chemical compound that our brain produces, which causes more adrenaline to be released.

There is a sharp jump in adrenaline, which then falls, and the person loses energy, the strength that caffeine gives. That is why after drinking coffee, first there is a surge of strength, and after the end of exposure, its sharp outflow, after which drowsiness or lethargy is felt.

Sweets also affect the brain. Read more about this here.

Procrastination. The more we are lazy, the more the brain fixes what we do not need to do, weaned from working, and the more it blocks us for other actions. If a person constantly avoids solving problems, then the brain receives a signal that it is not worth bothering yourself and wasting energy on it. The brain remembers the algorithm, according to which the fewer actions, the less effort it spends.

Detachment. When a person goes into his own thoughts or a fictional world, he is not in reality, the brain creates an alternative reality, which is an illusion. At the same time, in real life, a person either does not notice what is happening, or misses something important that is happening to him at the moment. This leads to decreased performance and concentration.

Aggression, malice. The habit of being angry is bad for the brain. One of the components of anger is cortisol. It has a negative effect, which especially affects the prefrontal cortex (PFC) of the brain and the hippocampus.

The prefrontal cortex is the most important part of the brain, in which the most complex processes take place, including thinking. Its functions include attention, logical thinking, memory, the ability to reason and plan.


The stress hormone cortisol, when released in excess, enriches neurons with calcium, which can eventually destroy cells. In excess, this hormone reduces the level of serotonin, which is responsible for good mood, feelings of joy and happiness. That is why anger devastates a person.

Rejection of an alternative point of view. If a person does not accept an alternative point of view, this indicates that the brain is blocking new information, experience, which leads to rigidity. Habits and old beliefs give the brain a sense of security and comfort, so the brain has no interest in losing that feeling.

It is difficult for such people to adapt to everything new, they are distinguished by perseverance and self-righteousness, which prevents them from developing and indicates a lack of flexibility in thinking. This affects relationships with other people, it is difficult for such people to find a common language with others.
