Humour is more than just a way to pass the time and make us feel better, it’s also the body’s natural way of healing and protecting us from the stresses of life. Laughter has long been known to be a great way to reduce stress and improve physical and mental health, but what is the scientific reason behind this?
The physical act of laughing is thought to trigger a cascade of physiological responses in the body that release a variety of chemicals. Endorphins, dopamine, serotonin, and other feel-good hormones are all released when you laugh, which can reduce stress, relax muscles, boost your mood, and improve your overall sense of wellbeing.
These hormones also help to reduce the body’s response to stress, by blocking the production of the stress hormones epinephrine and cortisol. This in turn can reduce the damaging effects of stress on the body, such as high blood pressure, headaches, and digestive issues.
Laughter also has a positive effect on the immune system. It can increase the production of natural killer cells, which are responsible for killing off viruses and bacteria. It also increases the production of antibodies, which help protect the body from infection.
Studies have also shown that laughter can improve cardiovascular health. It increases blood flow, which can reduce the risk of heart attack and stroke. It also helps to reduce levels of bad cholesterol, while increasing levels of good cholesterol.
Finally, laughter has been found to have positive psychological effects. It can help to boost your mood, reduce anxiety and depression, and increase your resilience to stress. It can also help to improve your relationships with others, as it brings people closer together.
Overall, laughter is a powerful tool for improving physical and mental health. The scientific reason behind why laughter is such an effective medicine is that it triggers a cascade of physiological responses in the body that release hormones, reduce stress, and improve immunity and cardiovascular health. So laugh away, and enjoy the health benefits that come with it!
