The Science of Kindness

Did you know there are scientifically proven benefits of being kind? Practice kindness all year round and especially on Random Acts of Kindness Week, Feb. 14-20, 2021. 

Kindness Increases Energy

“About half of participants in one study reported that they feel stronger and more energetic after helping others; many also reported feeling calmer and less depressed, with increased feelings of self-worth” Christine Carter, UC Berkeley, Greater Good Science Center. 

Kindness Increases Happiness

A 2010 Harvard Business School survey of happiness in 136 countries found that people who are altruistic—in this case, people who were generous financially, such as with charitable donations—were happiest overall.

Kindness Increases Lifespan

“People who volunteer tend to experience fewer aches and pains. Giving help to others protects overall health twice as much as aspirin protects against heart disease. People 55 and older who volunteer for two or more organizations have an impressive 44% lower likelihood of dying early, and that’s after sifting out every other contributing factor, including physical health, exercise, gender, habits like smoking, marital status and many more. This is a stronger effect than exercising four times a week or going to church.” Christine Carter, Author, “Raising Happiness; In Pursuit of Joyful Kids and Happier Parents”

Kindness Decreases Anxiety

A group of highly anxious individuals performed at least six acts of kindness a week. After one month, there was a significant increase in positive moods, relationship satisfaction and a decrease in social avoidance in socially anxious individuals. University of British Columbia Study.

Kindness Decreases Blood Pressure

Committing acts of kindness lowers blood pressure. According to Dr. David R. Hamilton, acts of kindness create emotional warmth, which releases a hormone known as oxytocin. Oxytocin causes the release of a chemical called nitric oxide, which dilates the blood vessels. This reduces blood pressure and, therefore, oxytocin is known as a “cardioprotective” hormone. It protects the heart by lowering blood pressure.

The positive effects of kindness are experienced in the brain of everyone who witnessed the act, improving their mood and making them significantly more likely to “pay it forward.” This means one good deed in a crowded area can create a domino effect and improve the day of dozens of people! Jamil Zaki, Assistant Professor of Psychology at Stanford University for Scientific American, July 26, 2016.
