With increasing age, I am ever more convinced that humour is a vital, multifaceted aspect of daily life that profoundly enhances our existence, serving as a powerful tool for improving physical health, boosting emotional resilience, and strengthening social bonds. Far from being a mere frivolous diversion, the ability to find amusement helps us navigate challenges, build connections, and foster a more positive, optimistic outlook on the world around us. Humour is great across the PIES: the physical, intellectual, emotional and spiritual dimensions of our human life.

The old adage that "laughter is the best medicine" is supported by scientific evidence, revealing real, measurable physiological benefits that contribute to overall well-being and can potentially lead to a longer, healthier life.

A good, hearty laugh activates and then cools down the body's stress response. This process decreases levels of stress hormones like cortisol and epinephrine while simultaneously triggering the release of neuropeptides and feel-good chemicals such as endorphins, dopamine, and serotonin. The result is a profound sense of relaxation and reduced anxiety, which can last for up to 45 minutes after the laughter subsides.

By lowering stress hormones, humour helps the immune system function more effectively. Laughter increases the number of immune cells and infection-fighting antibodies, thus improving the body's resistance to diseases and helping you get sick less often.

Mirthful laughter improves the function of blood vessels, increases blood flow, and lowers blood pressure, which helps protect against heart attacks and other cardiovascular problems.

The endorphins released during laughter act as the body's natural painkillers, temporarily easing pain and promoting an overall sense of well-being.

Laughter relieves physical tension and helps muscles relax. This, combined with a decrease in stress hormones, can significantly improve sleep quality and even help those with insomnia.

On a psychological level, humour is an essential life skill that helps us manage the inherent ups and downs of existence, from everyday frustrations to significant trauma and grief.

Humour provides a way to gain perspective and find lightness in dark or overwhelming situations. It serves as a healthy defence mechanism, allowing individuals to reframe challenges and avoid feeling overwhelmed, thus building emotional resilience.

Humour adds joy and zest to life, making it easier to maintain a positive, optimistic outlook even during disappointments or loss.

Humour encourages "outside-the-box" thinking and creativity. Studies have shown that individuals exposed to comedy perform better on creative problem-solving tasks, likely because laughter lights up brain areas associated with attention and decision-making.

Learning to laugh at oneself and one's mistakes—a positive, self-enhancing humour style—helps build self-confidence and self-acceptance, moving past embarrassment or defensiveness. This ability to forgive oneself can extend to forgiving others, fostering empathy and compassion. Humour keeps us not only young at heart, but young at an old age.

Recently, a man I baptised over 40 years ago was shown a photo of me taken this September. When told how old I was his retort was, “Eighty-six? He looks more like sixty-eight.” .

When I was told about this, I felt chuffed. Proper exercise, diet, sleep and humour has, so far, done its trick.

Humour is fundamentally a social phenomenon; we are far more likely to laugh when we are around others than when we are alone. It is a universal language that breaks down barriers and strengthens our bonds with friends, family, and colleagues.

Shared laughter creates a powerful, positive bond and a sense of camaraderie, acting as a buffer against stress and disagreements.

In professional and personal settings, humour can serve as an effective icebreaker, diffuse tension, and create a more collaborative and positive atmosphere. Leaders who use appropriate humour are often perceived as more approachable and confident.

A good sense of humour is consistently ranked as one of the most important qualities people look for in a partner and friends, as it enhances personal satisfaction and makes interactions more enjoyable.

To sum up, incorporating humour into daily life is not merely about having fun; it is a critical, free, and accessible resource for living a more fulfilled existence. From physically relaxing your muscles to building lasting relationships and giving you the strength to cope with life's darkest moments, humour is truly an essential ingredient for thriving. If you find yourself in a serious spell, try seeking out opportunities to laugh - watch a comedy, spend time with a funny friend, or simply try to laugh at yourself - it just might be the best thing you ever do for your overall health and well-being.

Having fun daily reduces anxiety, boosts your mood, and lowers cortisol levels. It keeps burnout at bay and helps you feel more emotionally balanced. Fun acts like a mental reset button. After laughing, playing, or doing something creative, your brain is sharper, and your focus improves.
