Kindness is like a campfire – it gives light, it gives warmth, and it brings people closer together.

I recently heard a story of a new mum in Canberra who returned to her car after a physically and emotionally taxing day, staying with her sick baby in hospital, only to find that an overly zealous parking inspector had added to her distress by issuing her with a parking ticket. She was initially distraught by the discovery, but when she opened the envelope, she found more than just the ticket. She also found a note from complete stranger who just happened to be passing by. The note read: “I saw your car had a parking ticket on it, I’m sure whatever you were going through at hospital is tough enough so I have paid for you … Hope things get better!”

It was such a small act, but the effects of this stranger’s kindness was so profound. The financial exchange was minimal, but the joy and hope it generated were enormous.

And that’s the thing about kindness. One of the best things you can do for your health and happiness is to be kind to other people. Altruism activates rewarding neural networks, essentially the same brain regions as those activated when receiving rewards or experiencing pleasure. Studies also show that both the hormones and the neurotransmitters in the brain involved in helping behaviour and social bonding can lessen stress levels and anxiety. The immune system and autonomic nervous systems are positively affected by the quality and extent of social networks, and increased sociability and concern for others’ wellbeing can improve immune system and stress responses.

But kindness isn’t just about what it does for us, but it’s also about what it does for those to whom it’s directed. The joy and hope of kindness is bidirectional. Like the story of the mum with the sick baby, the kindness of a stranger was a ray of light in an otherwise very dark time. Sometimes those simple acts can make the difference between someone getting through or giving up.

There are infinite ways to show kindness, but the thing that links them together is unselfishness, the “disinterested and selfless concern for the well-being of others”, or in less formal language, simply giving with no strings attached.
