The Science of Happiness

How to Cultivate Joy

In the hustle and bustle of our daily lives, we often find ourselves seeking one core emotion – happiness. Yet, how often do we pause to understand the science behind it? What makes us happy, and how can we nurture this emotion in our lives? Here we will explore the complex and fascinating science of happiness and share some tips to help you cultivate more joy in your life. 

Understanding Happiness

Happiness, in psychological terms, refers to a state of well-being and contentment. It can be categorised into two main types: hedonic and eudaimonic happiness. Hedonic happiness is associated with pleasure and the avoidance of pain, while eudaimonic happiness relates to living a meaningful life and realising one’s potential.

Research shows that our level of happiness is influenced by a mix of genetic, environmental, and personal factors. Studies suggest that approximately 40% of happiness is determined by our genes, 10% by our life circumstances, and a significant 40% by our daily activities and the choices we make.

The Neuroscience of Happiness 

Neurologically speaking, happiness is connected to several chemicals in our brain, including dopamine, serotonin, oxytocin, and endorphins. These chemicals, often referred to as “happiness hormones,” play a crucial role in regulating our mood, motivation, and overall sense of well-being.

Dopamine, known as the “reward” chemical, is released when we achieve a goal or enjoy pleasurable activities. Serotonin, the “mood stabiliser,” contributes to our feelings of well-being and happiness. Oxytocin, the “love hormone,” is released during social bonding, and endorphins, our natural painkillers, are produced during exercise, excitement, and even laughter.

Traditional Wisdom and Happiness

While modern science has provided much insight into the nature of happiness, traditional wisdom has long offered methods to cultivate joy in life. Many of these methods align with scientific findings and have stood the test of time. 

Mindfulness and Meditation

Eastern philosophies, such as Buddhism, have advocated for mindfulness and meditation as ways to cultivate happiness. Being mindful involves being fully present and engaged in the moment, which can help reduce stress and promote feelings of peace and contentment.

Modern scientific studies have supported these claims. Research indicates that mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) can significantly reduce symptoms of anxiety and depression, enhancing overall well-being.


Cultivating gratitude is another traditional practice that has been scientifically validated. It involves recognising and appreciating the good things in your life, which can shift your focus from what’s wrong to what’s right, promoting positive emotions. Studies show that maintaining a regular gratitude practice can increase happiness and reduce depressive symptoms.

Cultivating Joy: Practical Steps

Foster Positive Relationships

As social creatures, humans derive a significant portion of their happiness from their relationships. Prioritise spending quality time with family and friends, and seek to build strong, positive connections. 

Exercise Regularly

Physical activity is known to trigger the release of endorphins, the body’s natural mood lifters. Regular exercise can significantly boost your mood and reduce stress levels.

Cultivate a Growth Mindset

A growth mindset, which is the belief that our abilities and intelligence can be developed through dedication and hard work, can lead to higher achievement and increased motivation. Embrace challenges, persist in the face of setbacks, and view effort as the path to mastery.

Seek Meaning and Purpose

Rather than chasing fleeting moments of pleasure, seek to cultivate eudaimonic happiness by pursuing meaningful activities that align with your values and contribute to a sense of purpose.

The Role of Relationships in Happiness

Recent research has further highlighted the importance of relationships in fostering happiness. A Harvard study running since the 1930s has found that it’s not money but human connections that make people the happiest. This longitudinal survey, which examined happiness over decades, found that it is mostly relationships and the connections we forge that lead to the most contented people. Whether these connections are in the form of friendships, book clubs, romantic attachments, church groups, sports partners, or co-workers, the people with the strongest social bonds and connections in their 50s were in the best shape in their 80s.

This study underscores a critical point: happiness is not merely a destination that can be reached by ticking off certain boxes like buying a house, getting a promotion, or losing weight. Instead, it’s an attainable state of contentment that comes from nurturing strong, healthy relationships. As the authors of the study summarise, “good relationships keep us happier and healthier. Period”.

In Conclusion

The science of happiness is a complex field, intertwining genetics, brain chemistry, lifestyle choices, and our relationships. While we all may have different definitions of happiness, research and traditional wisdom converge on a few key points: nurturing strong relationships, practicing mindfulness and gratitude, exercising regularly, and seeking meaning and purpose in life are all essential for cultivating joy.

As we navigate our way through the ups and downs of life, let us remember that happiness is not an elusive goal but a journey. And on this journey, every step we take towards nurturing our well-being and fostering strong, positive connections with others is a step towards a happier, more fulfilling life.
