CNN  — 

This year’s Random Acts of Kindness Day falls on Friday, but you may want to consider being kind every day.

The foundation behind the day wants you to be a “RAKtivist,” or a “Random Acts of Kindness activist.”

Here’s why: Spreading kindness not only helps others feel better about themselves — it can also boost the giver’s health and happiness, according to research. It’s a win-win for all. Here’s why.

A ‘helper’s high’

Putting the well-being of others before our own without expecting anything in return — or what is called being altruistic — stimulates the reward centers of the brain, studies show.

Those feel-good chemicals flood our system, producing a sort of “helper’s high.” Volunteering, for example, has been shown to minimize stress and improve depression.

That’s not all: The same activity can also reduce the risk for cognitive impairment and even help us live longer.

One reason for this, experts say, is because kindness contributes to our sense of community and belonging. And that, studies have found, is a key contributor to a healthy, longer life.

Lower blood pressure

Giving donations to others, or “prosocial spending,” has been shown to reduce blood pressure and improve heart health.

One study asked a group of hypertensive people to spend $40 on themselves, while another group with high blood pressure was told to spend the money on others.

Researchers found that those who spent money on others had lower blood pressure at the end of the six-week study. In fact, the benefits were as large as those from healthy diet and exercise.

Pain reduction

Giving seems to lessen our pain. A 2019 study found that people who said they would donate money to help orphans were less sensitive to an electric shock than those who declined to give. In addition, the more helpful people thought their donation would be, the less pain they felt.

How could this happen? The study found that regions of the brain that react to painful stimulation appear to be instantly deactivated by the experience of giving.


In the UK, researchers found that being kind could boost happiness in as little as three days. The study assigned people to three groups: The first group had to do an act of kindness each day; the second tried a new activity, and the third did nothing. Those who were kind and did novel things saw a significant boost in happiness.

Spreading kindness doesn't have to be complicated.

You’ll experience even greater joy if you’re creative with your acts of kindness. Happiness researchers Sonja Lyubomirsky and Kennon Sheldon found that people who did a variety of acts of kindness throughout the week showed greater increases in happiness than those who performed the same activity over and over again.

And here’s the good news: It seems acts of kindness can be anonymous or visible, spontaneous or planned, and can be as simple as giving a compliment or opening a door for someone.

Kindness suggestions

OK, you’re convinced and want to jump right into being a kinder and more helpful person. There are literally hundreds of ideas on the internet, but here are a few to get you started:

  • While driving, make room for the car that wants to enter your lane.
  • Give a genuine compliment to a family member, friend or colleague (via text, email or video chat, please).
  • Do the same for your boss, who probably never get compliments!
  • Let go of grudges and tell people you forgive them (unless telling them makes it worse).
  • Be there for a friend having a tough time. Don’t try to fix it; just listen.
  • Leave your mail carrier a thank-you note.
  • Overtip your delivery person.

A gift to yourself

Want more ideas? The Random Acts of Kindness Foundation also has lists of kindness ideas, organized by work, community, environment, animals, strangers, kids, older people and more. If you become a “RAKtivist,” you’ll get a monthly kindness challenge designed to help a worthy cause or individual.

You’re making the world a better place, the foundation says. But don’t forget — any kindness you give to others is also a gift to yourself.
