Claudia Hammond in The Guardian:
I really enjoy doing it: it makes me feel good about myself. It gives me a boost, mentally and physically.” If these were your reactions to an activity, you’d surely be inclined to do it as often as you could. After all, aren’t a lot of us looking for ways to find more meaning in life and to be happier and healthier? What, then, is the act that elicits such positive responses? The answer: being kind.
A growing body of evidence from the fields of psychology and neuroscience demonstrates that performing kind acts increases mental wellbeing, enhances physical health and might even improve life expectancy. Kindness is not just beneficial for the recipient, but also for the giver.
In 2021 I worked with a team at the University of Sussex to create the Kindness Test. This online study was launched on BBC Radio 4, and more than 60,000 people took part. We found that the more acts of kindness people told us they carried out, the greater their wellbeing.
