Long-term effects

Laughter isn't just a quick pick-me-up, though. It's also good for you over the long term. Laughter may:

• Improve your immune system. Negative thoughts manifest into chemical reactions that can affect your body by bringing more stress into your system and decreasing your immunity. By contrast, positive thoughts can actually release neuropeptides that help fight stress and potentially more-serious illnesses.
• Relieve pain. Laughter may ease pain by causing the body to produce its own natural painkillers.
• Increase personal satisfaction. Laughter can also make it easier to cope with difficult situations. It also helps you connect with other people.
• Improve your mood. Many people experience depression, sometimes due to chronic illnesses. Laughter can help lessen your stress, depression and anxiety and may make you feel happier. It can also improve your self-esteem.
