Ever noticed that people who are kind have a tendency to be happier and more content?
This is because when we do something kind for someone else, we feel good - which is due to the release of dopamine and oxytocin.
Dopamine is the reward chemical that is released by the brain and makes us feel good as a result of something that we perceive as positive.
Oxytocin, responsible for emotional warmth, reduces blood pressure and promotes other cardiovascular benefits. It also reduces levels of free radicals and inflammation, thus slowing ageing.
Kindness also has obvious social benefits, making for better friendships and relationships.
