A great number of benefits have been reported to support teaching kindness in schools , best summed up by the following.

Patty O'Grady , an expert in neuroscience, emotional learning, and positive psychology, specializes in education. She reports that “kindness changes the brain by the experience of kindness. Children and adolescents do not learn kindness by only thinking about it and talking about it. Kindness is best learned by feeling it so that they can reproduce it.”

It seems there are good reasons why we can’t get enough of those addictive, feel-good emotions, as scientific studies prove there are many physical, emotional, and mental health benefits associated with kindness.

Phrases like “random acts of kindness” and “pay it forward” have become very popular, which can perhaps be best explained by those who have identified a deficiency in their lives that can only be fulfilled by altruism.

Happy, Caring Children

The good feelings that we experience when being kind are produced by endorphins. They activate areas of the brain that are associated with pleasure, social connection, and trust. These feelings of joyfulness are proven to be contagious, encouraging more kind behavior (also known as altruism) by the giver and recipient. Acts of kindness help us form connections with others which are reported to be a strong factor in increasing happiness.

Greater Sense of Belonging and Improved Self-Esteem

Studies show that people experience a “helper’s high” when they do a good deed. This rush of endorphins creates a lasting sense of pride, well-being, and belonging. It’s reported that even small acts of kindness heighten our sense of well-being, increase energy, and give a wonderful feeling of optimism and self worth.

Increased Peer Acceptance

Research on prosocial behavior among adolescents determined that being kind increases popularity and our ability to form meaningful connections with other people. Being well-liked is an important factor in the happiness of children and it was demonstrated that greater peer acceptance was achieved through good deeds. Better-than-average mental health is reported in classrooms that practice more inclusive behavior due to an even distribution of popularity.

Improved Health and Less Stress

There are a number of physical and mental health benefits that can be achieved by being kind. Altruistic actions trigger a release of the hormone oxytocin, which can significantly increase a person’s level of happiness and reduce stress levels. Oxytocin also protects the heart by lowering blood pressure and reducing free radicals and inflammation, which incidentally speed up the aging process.

Increased Feelings of Gratitude

When children are part of activities that help others less fortunate than themselves, it provides them with a real sense of perspective, highlighting their own good fortune. Being generous helps them appreciate what they have, makes them feel useful, and fosters empathy.

Better Concentration and Improved Results

Kindness is a key ingredient that enhances positivity and helps children feel good about themselves as it increases serotonin levels. This important chemical affects learning, memory, mood, sleep, health, and digestion. Children with a positive outlook have greater attention spans, more willingness to learn, and better creative thinking to improve results at school.

Reduced Depression

Internationally renowned author and speaker Dr. Wayne Dyer explains that an act of kindness increases levels of serotonin, a natural chemical responsible for improving mood. This boost in happiness occurs not only in the giver and receiver of kindness, but also in anyone who witnesses it.

Less Bullying

Shanetia Clark and Barbara Marinak are Penn State Harrisburg faculty researchers who say, “Unlike previous generations, today’s adolescents are victimizing each other at alarming rates.” They strongly believe that adolescent bullying and violence can be confronted with in-school programs that integrate “kindness—the antithesis of victimization.”

Many traditional anti-bullying programs focus on the negative actions that cause anxiety in children. When students are instead taught how to change their thoughts and actions by learning about kindness and compassion, it fosters the positive behavior that's expected and naturally rewarded with friendship. Promoting its psychological opposite is key in reducing bullying to create warm and inclusive school environments.

Maurice Elias, a professor in the Rutgers University Psychology Department, is also an advocate for kindness in schools. He says:

As a citizen, grandparent, father, and professional, it is clear to me that the mission of schools must include teaching kindness. Without it, communities, families, schools, and classrooms become places of incivility where lasting learning is unlikely to take place.... We need to be prepared to teach kindness, because it can be delayed due to maltreatment early in life. It can be smothered under the weight of poverty, and it can be derailed by victimization later in life.... Kindness can be taught, and it is a defining aspect of civilized human life. It belongs in every home, school, neighborhood, and society.

It’s become quite clear that modern education ought to encompass more than just academics, and that matters of the heart must be taken seriously and nurtured as a matter of priority.
