The Science of Happiness: Investigating What Makes Us Truly Happy

The Science of Happiness

Happiness is an elixir that every one of us is chasing. No matter where we go, what we do, or who we are, happiness remains an elusive phenomenon. While it can be found in trivial moments, such as enjoying a good meal, hanging out with friends, or listening to your favorite music, it can also be evasive and complicated to grasp. In recent years, a plethora of research has emerged across the fields of psychology, neuroscience, and positive psychology, attempting to uncover the science behind happiness. This article explores the latest findings on what makes us truly happy, and how we can apply these insights to our daily lives.

What is happiness?

Before delving into the science behind happiness, we need to define what happiness is. According to the Cambridge Dictionary, happiness is “the feeling of being happy.”

However, this is just a simple definition, as happiness is much more complex and multifaceted than a mere feeling. Psychologists have different approaches to defining happiness but one of the most commonly used is the “subjective well-being” theory, which posits happiness as a combination of two factors – emotional state and life satisfaction.

Emotional well-being refers to how we feel in the present moment, whether we are experiencing positive emotions such as joy, contentment, and love, or negative emotions like anger, sadness, and fear. Life satisfaction, on the other hand, refers to our overall perception of the quality of our lives, including our goals, relationships, achievements, and self-worth.

The Science Behind Happiness

The science behind happiness is a vast and growing field. In recent years, a body of research has emerged aiming to understand the psychological, social, and biological factors that determine our well-being. Here are some of the key insights into what makes us truly happy:

1. Money can’t buy happiness

Many of us believe that the more money we have, the happier we will be. However, research has consistently shown that there is a weak link between money and happiness. While having enough money to fulfill basic needs, such as food, shelter, and healthcare, is essential for our well-being, money beyond a certain threshold does not increase happiness. A study by Nobel laureate Daniel Kahneman and economist Angus Deaton found that income levels beyond $75,000 per year did not boost people’s emotional well-being. Another study conducted across 164 countries showed that the correlation between income and happiness is weak or non-existent in most cases. This is not to say that money is insignificant, but rather that it has a limited impact on our happiness.

2. Social connections are crucial for happiness

Humans are social animals, and our relationships with others play a crucial role in our happiness. Research has shown that people who have strong social connections tend to be happier and healthier than those who don’t. Positive relationships with family, friends, and romantic partners are associated with higher levels of happiness, life satisfaction, and emotional resilience. Social connections can provide emotional support, a sense of belonging, and an outlet for positive emotions. Conversely, social isolation and loneliness have been linked to a host of negative outcomes, including depression, anxiety, and physical health problems.

3. Gratitude promotes happiness

Gratitude refers to the practice of focusing on the good things in life and appreciating them. Research has shown that people who regularly practice gratitude tend to be happier, healthier, and more resilient than those who don’t. Gratitude can take many forms, such as keeping a gratitude journal, expressing appreciation to others, or simply savoring positive experiences. A study by psychologists Robert Emmons and Michael McCullough showed that people who kept a daily gratitude journal for ten weeks reported higher levels of happiness and well-being than those who didn’t. Gratitude can help us reframe our mindset from one of scarcity to one of abundance, and cultivate a sense of contentment with what we have.

4. Mindfulness enhances well-being

Mindfulness refers to the practice of being fully present in the moment, without judgment or distraction. It has a range of benefits for well-being, including reducing anxiety, depression, and stress, and promoting positive emotions such as joy and contentment. Mindfulness can be practiced through meditation, yoga, or simply paying attention to our thoughts, feelings, and sensations in the present moment. A study by psychologists Richard Davidson and Jon Kabat-Zinn found that mindfulness meditation training led to a significant increase in positive emotions and a decrease in negative emotions among participants.

5. Helping others boosts happiness

Altruism, or the act of helping others without expecting anything in return, can promote higher levels of happiness and well-being. When we help others, we experience a sense of belonging, purpose, and fulfillment, which can translate into positive emotions and greater life satisfaction. Helping others can take many forms, such as volunteering, donating money to charity, or simply offering a listening ear to a friend in need. A study by psychologists Sonja Lyubomirsky and Lara Aknin showed that spending money on others, rather than on oneself, can lead to greater happiness.


Happiness remains a complex and elusive concept, but research has shown that there are certain factors that can enhance our well-being. Money, while important, has a limited impact on our happiness beyond a certain threshold. Social connections, gratitude, mindfulness, and altruism have all been shown to promote happiness and well-being. By incorporating these practices into our daily lives, we can increase our emotional resilience, life satisfaction, and overall happiness. As the well-known saying goes, “Happiness is not something ready-made. It comes from your own actions.”     3:31 PM
