 What happens in the body when we laugh out loud

Laughter is an integral and natural part of human life, which gives us joy, excitement and lightness. It is not only an emotional expression, but it also has a profound effect on our physical, mental and social health. Various studies have shown that laughing out loud activates various biological and psychological processes in our body, which in turn benefits our overall health.

What changes occur in the body when we laugh out loud? What are their scientific bases and what are the effects they have on our lives?

1. Release of chemicals in the brain

When we laugh out loud, our brain releases various chemicals (neurotransmitters), which improve our mood. Chemicals such as dopamine, serotonin and endorphins increase during laughter.

Dopamine gives us a feeling of pleasure and happiness, serotonin reduces stress and stabilizes mood, while endorphins act as natural painkillers. According to a study by the Mayo Clinic, laughter helps reduce symptoms of anxiety and depression by increasing the levels of these chemicals.

For example, watching a funny movie or having a pleasant conversation has an immediate effect on the brain, which makes us feel positive immediately.

2. Reduction of stress hormones

Laughter reduces the levels of stress hormones, such as cortisol and adrenaline, in the body. A study by Loma Linda University has shown that laughing significantly reduces cortisol levels, which helps reduce stress and anxiety.

High levels of cortisol promote problems such as blood pressure, immune function, and diabetes. However, when we laugh, our body calms down the stress response. We can reach a calm and balanced state from a stressful situation.

3. Improved blood circulation

Laughter also has a positive effect on our circulatory system. A study by the University of Maryland has shown that laughter dilates blood vessels. Which improves blood flow. This process increases the supply of oxygen to the heart and brain and keeps blood pressure under control. Laughter also exercises the heart muscles, which reduces the risk of heart disease. For example, people who participate in a comedy session have been found to have lower blood pressure and heart stress, which is beneficial for long-term health.

4. Increased immunity

Laughter strengthens our immune system. Studies have shown that laughter increases the activity of T-cells and natural killer cells, which help fight viruses and bacteria.

In addition, laughter also increases the production of immunoglobulin ‘IgA’, which protects the respiratory system from infections. A study by Indiana University confirmed that people who laugh regularly have a lower risk of colds and other common infections. This is because laughter activates the body’s defense system.

5. Muscle exercise

When we laugh openly, our stomach, diaphragm, and facial muscles get exercise. This process contracts and relaxes the muscles, which improves blood flow and oxygen supply. When we laugh, our abdominal muscles get a workout that is similar to a light gym workout.

In addition, at the end of laughter, the muscles reach a state of complete relaxation, which reduces physical tension. This is beneficial for people suffering from muscle pain.

6. Pain control

Laughter acts as a natural painkiller. The release of endorphins and other chemicals reduces the experience of pain. A study conducted at the University of Oxford found that people who participate in the process of laughter have an increased ability to tolerate pain. People who watch comedy films experience less pain than in normal conditions. This effect is especially useful for people with chronic pain (such as arthritis).

7. Improves the digestive system

Laughter also activates the digestive system. When we laugh, the contraction of the diaphragm provides a gentle massage to the stomach and intestines, which increases digestion and intestinal motility. This process helps to reduce problems like constipation and indigestion. In addition, laughter reduces stress, which controls digestive problems caused by stress.

8. Improves mental health

Laughter benefits mental health in various ways. It reduces anxiety, depression, and stress. A study by Harvard Medical School has shown that laughter increases psychological resilience, which gives a person the strength to face life's challenges.

Laughter also strengthens social bonds, which reduces feelings of loneliness. For example, laughing with friends deepens social relationships and increases self-esteem.

9. Improves breathing

Laughter also benefits the respiratory system. When we laugh openly, our lungs take deep and rapid breaths, which increases the supply of oxygen. This process is similar to the pranayama of yoga. Additionally, laughter expels carbon dioxide accumulated in the lungs, which increases respiratory efficiency.

This is especially beneficial for people with asthma and other respiratory problems.

10. Social and emotional bonding

Laughter strengthens social and emotional bonds. It is a universal language, which connects people. When we laugh with others, our bodies release oxytocin (the hormone of love and trust), which deepens relationships. Research has shown that, ‘Laughter increases teamwork, empathy, and cooperation. For example, the use of humor in the workplace increases employee morale and productivity.

Long-term effects

Regular laughter provides long-term health benefits. It improves quality of life, increases lifespan, and reduces the risk of diseases. A study in Norway has shown that laughter promotes good feelings and such people live longer.

In particular, there is a greater chance of avoiding diseases such as cancer. In addition, laughter encourages a positive outlook, which provides mental strength to deal with life’s difficulties.
