What does happiness mean to you? It can be the excitement of achieving a goal, the comfort of being with loved ones, or simply a moment of peace after a long day.
Happiness holds different meanings and perspectives for everyone, yet one thing remains constant—it’s deeply connected to our mental well-being. Happiness isn’t just an emotion, it’s a crucial part of a healthy and fulfilling life. The more you become happy, the better your mental health will be.
As we celebrate International Day of Happiness on 20 March every year, the 2025 theme Caring and Sharing reminds us of the power of kindness and generosity. It’s the perfect time to reflect on what happiness truly means and create a healthy environment where everyone can grow.
Let’s discuss how mental health and happiness go hand in hand—and how prioritising one can help nurture the other.

The Relation of Happiness and Mental Health

Happiness and mental health are deeply interconnected. Whether we see happiness as a goal or the essence of life, it’s always a reflection of our emotional well-being. When our mind is in a good state, we naturally feel more joy, resilience, and fulfillment in life. But when mental health struggles arise, even the happiest moment can feel far.
Stress, anxiety, and emotional struggles make it difficult to enjoy life, no matter how many good things are around. That’s why mental health isn’t just about avoiding negativity, it’s about creating an inner space where happiness can thrive.
A happy mind is more open to positivity, growth, and new opportunities. By choosing happiness we create a long-term impact for better growth. Since mental well-being directly impacts happiness, here are practical ways to nurture both.

Ways to Improve Mental Health for Lasting Happiness

Happiness doesn’t involve short-term joy but creating nurturing moments of happiness to grow and thrive. Here are some of the listed ways to build long-term happiness by taking care of your mental health.

Happiness: A Part of Something Bigger

Happiness is more than just a personal feeling, it’s deeply connected to our sense of purpose, relationships, and mental well-being. The more we become happier the more we can contribute greater and better for ourselves.
However, happiness isn’t a destination, it’s a continuous process of self-awareness and emotional balance. It is found in the moments of calm, fulfilling meaningful work, and appreciating the little things around us.
Rather than chasing happiness, the focus should be on creating an environment- both internally and externally- where happiness can naturally exist within you. By prioritising mental health, we lay the foundation for a long-term fulfilled, and balanced life.
