To feel good, almost everyonepeople need to attend festivals, holidays and other big events at least occasionally. This is true even for ardent introverts - yes, after such a shake-up, it will be necessary to replenish the charge of your “social battery”, but you can’t do without communication. Scientists believe that the need for regular communication with people is due to the fact that the human brain has evolved to a greater extent to support social connections. However, today more and more people are isolating themselves from society for various reasons - sometimes at will, and sometimes forced (remember the peak of coronavirus restrictions). Based on all this, it is logical to assume that isolation somehow affects the state of the brain. Recently, scientists once again decided to test this.

How communication affects brain health
Why once again?But because different groups of researchers regularly study the relationship between a person's social activity and the state of his brain. For example, in 2021, scientists created a brain map of 7,000 people and studied the departments that are responsible for social interaction. It was found that these areas are closely related to the ability of a person to make the right decisions, remember information, maintain motivation, control emotions, and so on. That is, the regularity of communication with people directly affects the most diverse abilities of our body.
What happens if you don't talk to anyone
In the course of a new scientific work, the results of whichwere published in the scientific journal Neurology, the researchers decided to take a closer look at how social activity affects the gray matter. For reference, we note that gray matter is usually called the outer layer of the brain, which consists of neurons. In the course of scientific work, researchers compared the brain state of 500,000 rarely communicating people at the age of 57 with the performance of 32,000 socially active volunteers.
The comparison showed that people with a deficiencycommunication, poorer cognition is observed: they have worse memory and reaction times, as well as a smaller amount of gray matter in many parts of the brain. For example, the volume of gray matter turned out to be lower in the temporal region, which processes sounds and plays a large role in long-term storage of information. The same can be said about the frontal lobe, which is responsible for concentration and planning. In addition, processes that are involved in the development of Alzheimer's disease were observed in socially isolated people (there are four types).
Interesting fact: young and old people experience loneliness differently. Here is the explanation.
Why loneliness destroys the brain
Loneliness has a bad effect on the state of the brainbrain - now it's clear. But because of what exactly there is a decrease in the volume of gray matter, scientists do not know exactly. In most cases, in the absence of communication, people suffer greatly from stress. But earlier, my colleague Lyubov Sokovikova already talked about the fact that chronic stress greatly changes the structure and function of brain cells, and not for the better. It turns out that the reason for the destruction of the brain may be stress caused by a lack of communication.
It is worth noting that loneliness causes stress even in insects. For example, flies do not get enough sleep and begin to overeat.
But there is another possibility, perhapsIn the absence of communication, the human brain does not receive a load sufficient to keep it in good shape. Scientists once studied the brains of taxi drivers who have to memorize a huge number of routes. It turned out that they have a rather large volume of the hippocampus - a part of the brain that plays a large role in the spatial memory necessary for navigation. That is, the more often a person uses different areas of his brain, the better they train. Based on this, it can be assumed that when communicating, the human brain also works well and trains, and in the absence of social ties, it begins to degrade.
How to keep your brain healthy
To maintain good brain function,it needs to be constantly developed. You can do this in a variety of ways, from reading books to solving mathematical problems. But it’s even better if a person regularly learns something new, like a language or a musical instrument – during these classes, new neural connections are actively formed, which will certainly improve the speed of thinking, memory, and other brain functions. Of course, we must not forget about maintaining an active lifestyle and maintaining a healthy diet.
Based on the results of the abovestudies, it turns out that for brain health you need to communicate with people regularly. Young people are unlikely to have serious problems with this. But something needs to be done with the elderly - the authors of the scientific work propose to hold mass events for socially isolated people, where they can communicate.
