Did you know? Helping others activates the brain's reward system, giving you a natural 'helper's high'—a boost in mood and energy.
The concept of the "helper's high" arose in the 1980s, and has been confirmed in various studies since then. It consists of positive emotions following selfless service to others.
Greater health and increased longevity are associated with this psychological state. Generosity, selflessness, and an extended sense of self favor our ability to confront successfully the environmental challenges we face on our planet.
There is a body of research that supports this. Scientific studies have been done to research how helping others effect the body and the brain.
Not only does volunteering immediately effect the brain, but over time continual volunteer experiences have an impact on life span. Basically, acts of kindness lower stress levels.
