Random Acts of Kindness Week is February 10th thru the 16th. The Random Acts of Kindness foundation is an internationally recognized non-profit organization founded on the powerful belief in kindness - and dedicated to providing resources and tools to encourage kindness around the globe.
Research shows that tiny acts of kindness ripple exponentially across social experiences - essentially sparking a contagiousness of generosity and cooperativeness. Simple stated, a single kind act influences dozens more. Kindness - especially spontaneous acts of kindness - surge the feel good hormone dopamine in both the giver and the receiver.
