Long-term effects

Laughter isn't just a quick pick-me-up, though. Laughter also may:

• Help your immune system work better. Laughter can lower stress hormones that can weaken the immune system, such as cortisol. Laughter also boosts certain immune cells that fight illness.
• Relieve pain. Laughter may ease pain by causing the body to produce its own natural painkillers. It also shifts your focus away from feeling uncomfortable.
• Increase personal satisfaction. Laughter can make it easier to cope with tough situations. It also helps you connect with other people.
• Boost your mood. Many people have depression, sometimes due to chronic illnesses. Laughter can help lessen your stress, depression and anxiety. It also may make you feel happier. And it also can improve your self-esteem.
