Why is a hearty chuckle good for you?

One of the most natural ways we can boost our health is laughter. Whether it’s a pet doing something cute, your favourite sitcom or a devilishly funny joke, a good chortle helps the body return to a more desirable state. What’s more, it’s contagious!

We all intrinsically know laughter is good for us. As children, we laughed a lot. As adults, life becomes more serious, and the number of times we laugh each day reduces.

That’s a shame because the phrase “Laughter is the best medicine” may have some truth behind it. Here are some reasons why.

Relieves symptoms of anxiety and depression

A review published in Social Science and Medicine analysed numerous studies on laughter and psychological wellbeing and found although more rigorous research needs to be done laughter may help manage symptoms of depression, anxiety and alter perceptions of stressful events.

Relaxes the body

You know the feeling when you’ve laughed so much your body goes limp. Laughter releases those clenched muscles and helps the body relax. After all, it’s difficult to be anxious or angry and laugh at the same time. A small study found stress hormones reduced in the blood after watching a sixty-minute funny video.

Strengthens the immune system

Stress and negative thoughts trigger hormones such as cortisol, adrenalin and other chemicals that suppress the body’s immunity. Conversely, some evidence suggests that laughter improves resistance to disease by increasing antibodies and natural killer cells, which have cancer-protective effects.

Reduces pain

A review published in The European Journal of Pain found humour increased pain tolerance and helped with anxiety, stress, loneliness, and increased life satisfaction. Scientists speculate that comedy acts as a distraction from pain. Another hypothesis is that when people laugh, endorphins are released – chemicals naturally produced by the nervous system to cope with pain or stress, blocking pain messages from reaching the brain.

Promotes longer life

When researchers analysed data from a 15-year study of more than 53000 people, they found women with a high sense of humour had a reduced risk of death despite illness, especially from cardiovascular disease and infection. Men with high levels of humour had less chance of dying from infection only.

Helps build resilience

Research published in the Journal PLOS ONE found that the people who laughed the most in everyday life fared better when managing stressful life events.

Laughter builds social relationships.

When humans communicate, we mirror each other: we learn that as babies. So when someone is laughing, it’s difficult not to laugh or smile as well. Laughter is contagious and draws people together, diffuses conflict and keeps the spirits up in challenging situations.

Introduce laughter into life:

Find something funny in something that would usually annoy you.

Laugh at yourself more often. We’re all idiots at times.

Introduce things that make you smile into your environment.

Seek out humorous films, podcasts, jokes, or animal videos.
