Scientific research shows kindness brings both physical and mental benefits to those that show it, receive it or even witness it.
An act of kindness has been shown to build your energy levels, and lead to a longer life span.
Physically, an act of kindness has been shown to reduce pain and blood pressure. It also stimulate the production of serotonin - the feel-good chemical - and oxytocin - the love hormone.
Mentally, an act of kindness promotes happiness and pleasure, reducing anxiety, stress and depression.
At a time of a global pandemic, social strife and economic hardship, kindness makes us feel like we belong to a community, brings us connection and wards off feelings of loneliness.
