For you — 10 things that negatively affect the brain.
Lack of breakfast
Skipping a morning meal negatively affects a person's performance and tone during the day. This seems quite obvious, but the point here is not so much in the consumption of the energy needed by the body, as in the fact that the absence of breakfast lowers blood sugar levels. And this, in turn, makes it difficult for nutrients to enter the brain.
Excess sugar
The previous paragraph explains why it is recommended to eat sweets, especially bitter chocolate, for the productive work of the brain. However, excessive amounts of sugar cause problems with the absorption of protein and nutrients. The result is the same as with low blood sugar: nutrients simply do not enter the brain.
Stress
Strong psychoemotional tension leads to a rupture of connections between neurons and makes it difficult to understand cause-and-effect relationships and the sequence of events. This is associated with a strong nervous excitement and a feeling that everything is falling out of hand. Accumulated stress impairs memory and reduces intellectual potential.
Antidepressants and sleeping pills
The problem of craze for potent drugs is most relevant in the United States, where such medications are prescribed very easily. The use of sleeping pills and popular antidepressants like xanax can worsen memory up to amnesia, cause dementia and obsessive suicidal thoughts.
Smoking
If we talk about the negative effect of smoking on the body, the first image that comes to mind is the image of black lungs and damaged teeth. At the same time, quite little is said about how cigarettes affect the brain: nicotine narrows its vessels. However, cognac expands back. In addition to the problems associated with a lack of nutrients in the brain, this greatly increases the risk of Alzheimer's disease.
The sun
The lack of sufficient sunlight directly affects a person's cognitive abilities. Firstly, the ultraviolet light received from sunlight regulates blood circulation, that is, the influx of oxygen and nutrients. Secondly, sunlight contributes to the production of serotonin, a hormone that affects a person's mood.
Lack of water
Lack of water causes a decrease in the volume of the brain, which significantly reduces its efficiency and leads to almost zero ability to remember information. It is recommended to consume an average of 2 liters of water per day.
Excess of information
Year after year, the amount of information assimilated by a person increases avalanche-like. It would seem that this is brain training and maintaining its tone. In fact, this is an excess to which the brain responds unequivocally — with resistance. It is expressed by the fact that at some point the information ceases to be assimilated up to memory lapses.
Multitasking
Another anomaly of the information world: a person simultaneously perceives several streams of information. As a result, none of them is assimilated properly, and the consciousness gets used to such a mode of operation. Information is perceived superficially, and it becomes increasingly difficult to concentrate and do one thing without frequent changes of activity.
Lack of sleep
This phenomenon, familiar to everyone, is becoming a global problem. According to WHO, over the past 100 years, people have started to sleep an average of 20% less. Severe lack of sleep is fraught with the fact that in the actual state of wakefulness, various parts of the brain go into the phase of slow sleep. At this time, a person "freezes" at one point, becomes dispersed, fine motor skills deteriorate. Regular lack of sleep leads to the death of brain cells.
