From a scientific point of view, Brant points out that the activity of making friends is associated with the release of a variety of neurotransmitters and biochemicals that produce pleasure.

Among them, oxytocin and endorphins play the biggest role.

Friends are the "right hand" to promote health.

Making friends has at least five major benefits.

1. Less likely to get sick

Brandt said, to the lack of friends or long-term poor interpersonal relations, the body's stress hormone cortisol levels tend to be too high, and this chronic tension can damage health.

This also explains why lonely people have a higher risk of cardiovascular disease and are more susceptible to infection.

But if you have friends, cortisol is reduced, and people are relatively less likely to get sick.

2. Sleep better

The University of Chicago study found that the more lonely people have insomnia, the more often.

A Swedish study also showed that the lack of friends often suppresses and hides their feelings, more prone to insomnia, and may induce depression.

3. Better memory

Dr. Lisa Berkman, of the Department of Human Development and Health at the Harvard School of Public Health, found that compared to the elderly who socialize a lot.

The elderly who socialize less have twice the rate of memory loss.

He said socializing improves age-related memory loss and can develop the full potential of the brain.

4. Smarter

Oscar Barra, a professor at Michigan State University, found that making friends can make people smarter because making friends requires dealing with strangers, which equates to cognitive exercise.

For example, we have to extract from the brain "database" of sports, entertainment, life, fashion, and other topics of interest to different people, the cerebral cortex will always be in a state of excitement.

5. Longevity

Australia's Flinders University's Lynn Eales research found that with more than five close friends who have been in contact with the elderly, the mortality rate is reduced by 22%, an average life extension of 7 years.

Fu Chunsheng said that sharing hardships can make sorrow halved and sharing pleasure can make happiness multiplied, probably because friends can help people to relieve stress, solve difficulties, get support, and work together to maintain healthy habits and so on.

Interpersonal relationships are an important way to exchange information and acquire knowledge.

Modern society is an information society with an unprecedented amount of information and high information value.

People's demand for all kinds of information and use of information is increasing with the amount of information.

Through interpersonal relationships, we can pass information and results to each other, enrich our experience, broaden our insights, broaden our horizons, enliven our minds and inspire our thoughts.

Interpersonal relationships are necessary for collective growth and social development.

Interpersonal relationships are the bond that coordinates a collective relationship and forms a collective synergy.

A good group can contribute to the formation of a good personality in young students.

Good interpersonal relationships can also enhance the collective cohesion of students and become the most important educational force in the group.

An interpersonal relationship is an interaction between people.

The ability of good interpersonal relationships is positive and on the contrary, is not conducive to the overall healthy development of the individual.
