While some of the studies in the field of positive psychology are old, many of them are recent, and they all come to the same conclusion: #Happiness is good for you! Click To Tweet

Happiness is the most important thing we want for the people we love. We always want our loved ones to be happy, sometimes even at the cost of our own happiness.

But why is happiness important for us? What research in the field of positive psychology tells us about the A’s and B’s (advantages and benefits) of happiness?

Science says happier people are more successful and more productive. They are kinder and altruistic, physically healthier, and mentally stronger. Studies show they have better relationships and marriages.


Benefits of Being Happy: Advantages of Happier People

A few benefits that happier people have are:

1. Happy People Are Healthier

Happy people have better physical health and report fewer unpleasant physical symptoms. They have much fewer hospital and emergency room visits, call their doctor less frequently, use less medication, and have fewer work absences. They also experience less pain.

Happy people have better mental health than their less happy social group members. They have fewer symptoms of mental diseases, such as hypochondriasis, schizophrenia, social phobia, anxiety, or depression. Happy people are also less likely to report a history of drug abuse.

Jose de Jesus Garcia Vega, Professor of Economics and the Director of the Center of Well-being Studies at the University of Monterrey, Mexico, has famously written in the World Book of Happiness:

It is often said that people spend the best years of their life trying to make money and sacrificing their health and their family, only to spend the rest of their days paying that same money to recover their lost health and their estranged family!

Overall, the happier people have less depression and suicide, and greater self-control and coping skills. They also live longer on average, up to 10 years more. [The Nun Study]

Heli Koivumaa-Honkanen, Professor of Psychiatry at the University of Eastern Finland and Kuopio University Hospital, Finland, whose research found dissatisfaction in life is linked to a higher risk of death in disease, says:

Healthy people are not happier. The reverse is true: happy people are healthier.

2. Happy People Have Better Relationships And Marriages

Relationships are of utmost importance for the creation of our happiness. When we stay socially connected to our community, friends, and family, we are happier, healthier, and live longer.

Happy people have more friends and better social support and are more satisfied with their friends and their activities together.

In one study, the researchers found the top 10 percent of the happiest college students to have high-quality relationships. They were less jealous and had stronger contact with their family members.

My empirical study of well-being among 1,600 Harvard undergraduates found a similar result — social support was a far greater predictor of happiness than any other factor, more than GPA, family income, SAT scores, age, gender, or race.

In fact, the correlation between social support and happiness was 0.7. This may not sound like a big number, but for researchers it’s huge—most psychology findings are considered significant when they hit 0.3.

The point is, the more social support you have, the happier you are. — Shawn Achor

Happy people also have more fulfilling marriages. Marriages are more likely to succeed when couples experience a 5:1 positive ratio. [The Gottman Institute]

They tend to have more satisfaction in their marriages. Researchers have found there is indeed a strong relationship between happiness and satisfaction with marriage and family.

Happy people who are either married or in committed relationships more often describe their partner as being their “great love” than their less happy friends.

3. Happy People Have More Friends And Are More Prosocial

Happy people are more prosocial, that is they seem more inclined to help others. Happy people volunteer at higher levels than their unhappy friends and colleagues for charity and community service groups, as religious, political, health-related, and educational organizations.

Have you heard of a thing called Facebook envy? It’s when you have negative feelings after scrolling through your friends’ social media life. If you’re troubled by that, even occasionally, then check out how to get over it.

4. Happy People Are More Successful

Success doesn’t make us happy; but being happy makes us successful, as many studies have proved. Happiness also makes you more productive.

Happy people are more satisfied with their jobs, are more productive, and earn more than their colleagues. They also make better and faster decisions.

In fact, the economists at Warwick University found people primed to feel happy during an experiment were 11% more productive. Companies with happy employees perform better than the stock market index year after year.

Happiness improves your ability to problem-solve. Happy doctors make faster and more accurate diagnoses.

In a 2007 study that followed over 6,000 men and women aged 25 to 74 for 20 years, Laura Kubzansky, Professor of Social and Behavioral Sciences from Harvard T.H. Chan School of Public Health, found emotional vitality — a sense of enthusiasm, hopefulness, and engagement in life — appears to reduce the risk of coronary heart disease in both men and women.

Kubzansky found that optimism cuts the risk of coronary heart disease by half. She wrote in her paper:

Findings suggest that individuals with higher levels of emotional vitality had reduced risk of developing CHD during a 15-year follow-up period. Further analyses indicated that one mechanism underlying this relationship may be health behaviors.

Greater emotional vitality was significantly associated with less smoking, higher alcohol consumption, and more physical activity; after including these behaviors in the models, the relationship between emotional vitality and incident CHD was attenuated.

However, the association remained significant after controlling for these behaviors as well as a history of psychological problems, use of psychotropic medications, current depressive symptoms, and other covariates.

5. Happy People Are More Resilient

Happiness is about being able to make the most of the good times—but also to cope effectively with the inevitable bad times, to experience the best possible life.

Resilience is our ability to bounce back from hardships. Resilient people not only recover but also often find meaning in those bad times and their harsh experiences, and grow afterward.

Researchers found higher levels of resilience linked to lower levels of psychological distress.

Another research found psychological resilience may be a resource to increase life satisfaction and happiness, and reduce psychological distress in chronically ill patients.

Insights on Happiness Benefits

Why should we prefer to be happy when we could be our everyday selves, or even unhappy?

Why do most people try to be happy? It’s popular to say it’s because they want to enjoy their life, but the question still remains: why do they want to be happier?

We need happiness in our lives because happiness has many advantages. As the science of positive psychology shows, being happy has multiple benefits. Happier people are way ahead of others in many positive aspects, as science has proven over the last 20+ years.

After years of research, psychologists have found a happy person is more likely to succeed at work, make friends, and be more productive. Not only that, but being happy makes us feel better in general and even makes us more attractive to others. The benefits of happiness are often overlooked, but they can be profound. The right attitude can be the key to lasting happiness.

Scientists have been studying happiness for a long time, and they have found many positive effects of happiness: less aggression, more compassion, higher self-esteem, less anxiety, lower blood pressure, and a longer lifespan.

When we are happy, we feel better about ourselves; we make others around us happier and are more productive.

A large-scale study of over 2,400 British adults found those who scored high on measures of life satisfaction and lived in areas with high levels of sun exposure, reported experiencing an average of 16% higher levels of life satisfaction.

In comparison, those who scored well on the same measures but lived in areas of low solar exposure.

Research studies on happiness consistently point to higher levels of happiness because of increased self-esteem and a sense of well-being, and lower levels of stress. But do these changes last? The answer is yes—in the long term. According to the latest research, the benefits of happiness include a stronger immune system, higher self-esteem, and lower levels of anxiety.

According to the science of positive psychology, happiness is a choice. It is not the result of genetics or luck, but a choice you make to become a more satisfied and content person. Positive psychology can help you overcome negative thoughts and automatically make a choice that will put you on the path to a happier, more productive life.

Positive psychology is the study of human strengths and virtues. This branch of psychology looks at what makes people happy. As a topic, positive psychology has exploded in recent years, and it’s become a hot topic for researchers, thinkers, and entrepreneurs alike. In the past few years, there have been many studies focusing on the positive effects of happiness, and they are increasing in number by the day.

A 2020 research found there a growing class divide in happiness. While many of the “have nots” of the economy became increasingly unhappy, the happiness advantage favoring the “haves” has expanded between the 1970s and the 2010s.

Final Words

By the way, a skill is the ability to do something well. It is a capability you develop through practice or experience. And happiness is a skill that can be learned and honed. And it should be learned because it can help you live a more fulfilling and meaningful life.

Dennis Prager says happiness is a moral obligation.

In closing, let’s ask: Is it easier to cry in a BMW than on a bicycle?


  • Does happiness increase immunity?

    Scientific evidence suggests being happy may boost our immune system. Sheldon Cohen and his colleagues (2003) found people who were happy, lively, calm, or exhibit other positive emotions like optimism, were less likely to become ill when exposed to a cold virus than those who reported fewer of these emotions. They also found when happy people did come down with a cold, they had fewer symptoms.

    A 2006 study by Cohen had the same result: people who reported positive emotions were less likely to catch colds and were also less likely to report symptoms when they did get sick.

  • Can a person learn to be happier?

    Yes, happiness is a learnable skill. You can learn to be happy. You can teach yourself and others to be happier. Research shows our happiness levels can change notably over our lifetimes, and that itself suggests happiness may be a skill that can be learned over the years.

    Richard J. Davidson, a professor at the University of Wisconsin-Madison, has found mindfulness training for even 2 weeks, for 30 minutes a day, can result in measurable changes in the brains of the participants. This ability of the brain to change its form and function is called neuroplasticity. He suggests, therefore, that we can raise our happiness levels by regular practice of mindfulness.
    Davidson says, “Everything we’ve learned about the brain suggests that it’s (i.e., happiness is) no different than learning to play the violin or learning to engage in a complex sport. If you practice at it, you’ll get better at it.”

    And Matthieu Ricard, molecular geneticist, author, and a Buddhist monk, says, “Happiness is a skill, but it is a skill that has many components, and each of those components are constructive ways of being, like altruism or benevolence, compassion, inner peace, inner strength, inner freedom.”
