Liputan6.com, Jakarta - International Day of Happiness falls on March 20, 2026, and it is the perfect time to reflect on joy. Whether you feel happy every day or just sometimes, there are many fun facts about happiness that may surprise you and change the way you see life.

Happiness is not just a good feeling. It can protect your health, strengthen your relationships, and even help you live longer. Scientists have studied happiness for many years and found that it plays a big role in almost every part of our daily lives.

Are you ready to learn more? In this article, we have collected ten fun facts about happiness that are backed by science. Let us dive right in and discover what makes us smile.

Did you know that being happy can help protect your body from getting sick? A study published in the journal Psychosomatic Medicine found that people with more positive emotions are less likely to catch a common cold. Happiness may reduce stress hormones in the body, which helps the immune system work better. So, staying in a good mood could be one simple way to stay healthy.

Money and happiness have a complicated relationship. Research by Princeton professors found that earning more money does make people happier, but only up to a point. Once a person earns around $100,000 a year, extra money has less effect on daily joy. However, having enough money for basic needs is important. It is not about being rich; it is about feeling financially safe and secure.

Happiness can spread from one person to another, just like a cold, but in a good way. A study in the British Medical Journal found that having a happy friend can boost your own happiness by up to 15%. Simply spending time with cheerful people can lift your mood. So, the next time you are feeling low, try surrounding yourself with positive and joyful people.

Hugging does more than feel good in the moment. A study published in the International Journal of Environmental Research and Public Health found that people who hugged more during social interactions had lower cortisol levels the next morning. Cortisol is a stress hormone, so lower levels mean less stress. The study suggests that hugs may act as a safety signal for the body, helping it feel calmer and more at ease.

Feeling happy may actually help your body hurt less. A 2005 study in the Journal of Consulting and Clinical Psychology looked at women with arthritis and chronic pain. Those who experienced more positive emotions, such as happiness and enthusiasm, reported feeling less pain. While happiness is not a medicine, keeping a positive mindset may help reduce how strongly the body feels and responds to physical pain.

Spending time with animals can be a great source of joy. When you interact with a pet, your body releases oxytocin, which boosts happiness and reduces stress. Studies also show that pet owners tend to feel less lonely and more connected. Dogs encourage you to go outside and stay active, while even watching a cat rest quietly nearby can calm the mind and improve your mood.

It turns out that being kind is good for you, too. Studies show that people who donate to charity or perform acts of kindness feel happier than those who spend only on themselves. Doing something good for another person triggers feelings of reward in the brain. Even small gestures, like buying a coffee for a stranger, can create a lasting feeling of warmth and satisfaction.

Listening to music that you enjoy is one of the easiest ways to lift your mood. A study in the Journal of Positive Psychology found that people who listen to uplifting music are more likely to experience positive emotions. Music can reduce stress, increase energy, and even help you feel more motivated. Next time you are having a hard day, try playing your favorite happy song.

The phrase "stop and smell the roses" may actually be good advice. Researchers at Rutgers University found that people who are exposed to floral scents are about three times more likely to report feeling happy. The smell of flowers appears to have a direct positive effect on our emotions. If you want a simple mood boost, try placing fresh flowers in your home or workspace.

Nature has a powerful effect on how we feel. A study in the journal Global Environmental Change found that being outdoors makes people happier. The best spot? Near water on a warm day. Fresh air, natural light, and green spaces can all lift your mood quickly. Even a short walk outside during the day can help reduce stress and bring a small but real sense of happiness.
