Why giving back and act of kindness is scientifically beneficial for our body and mind

We all have our different life paths, stresses and strains, unexpected curve balls our way, and all the ups and downs of our life journey driven by unquestioning hope, but have you ever wondered how despite of all this, your face lights up when someone is being kind to you, or how you feel uplifted when you pay gratitude to someone or be the reason of their happiness? In this fast-paced world of loneliness, illness, and trauma, there’s only one thing that can unite us all together and preserves our peace of mind, and that is kindness and the act of giving back. 

What is kindness? Psychology defines kindness as a behavioral response of compassion or an action of great virtue and wisdom that is motivated by a desire to help another person. We all can bring a positive change in this world. All it takes is one small act of kindness. Small changes can make a big difference and be beneficial for our body and mind in multiple ways. Multiple studies have explored how an act of giving back is affecting us physically, mentally, and emotionally. Giving back involves paying gratitude, sending a gift to someone, doing something for a good cause, or even smiling or praying for people around you. Simply put, kindness is fundamental to human existence. (1)

Science of kindness and giving back: How it affects your brain?

Numerous studies have shown that being kind to others is not only good for your mental health but also your physical and emotional wellbeing. An act of kindness boosts the serotonin in the body, making one feel enthusiastic and uplifted. Serotonin is a body’s feel-good hormone, and when a person is kind towards others, it releases in the body and acts as an antidepressant, hence making you happy. Acts of kindness increases the amount of the love hormone or the bonding hormone, known as oxytocin, which aids in improving self-esteem and overall heart health. The oxytocin makes a person give more, and feel more happy and connected. (2)

When you give to another person, our body responds to it amazingly. The act of giving benefits the giver more than the recipients. Our brains’ reward center activates up as soon as we cultivate good deeds of kindness and giving back. Being kind to someone and paying them gratitude lights up our brain, it alleviates stress by reducing cortisol and creates a harmony between our heart and brain. Smallest acts of kindness benefit humans in everyday life by producing ripple benefits and improving overall well being. Many researches have also proved that kindness boosts neurotransmitters in the brain known as endorphins, which interact with opiate receptors and reduces pain. Isn’t it amazing how just one simple act of kindness can make you want to be more generous and have an enormously positive effect on your brain? (3)
