The Benefits of Laughter

What can laughter do?:



  • Lower blood pressure
  • Increase vascular blood flow and oxygenation of the blood
  • Give a workout to the diaphragm and abdominal, respiratory, facial, leg, and back muscles
  • Reduce certain stress hormones such as cortisol and adrenaline
  • Increase the response of tumor- and disease-killing cells such as Gamma-interferon and T-cells
  • Defend against respiratory infections–even reducing the frequency of colds–by immunoglobulon in saliva.
  • Increase memory and learning; in a study at Johns Hopkins University Medical School, humor during instruction led to increased test scores.


  • Improve alertness, creativity, and memory





Laughter makes you feel good. And the good feeling that you get when you laugh remains with you even after the laughter subsides. Humor helps you keep a positive, optimistic outlook through difficult situations, disappointments, and loss.


  • Laughter relaxes the whole body. A good, hearty laugh relieves physical tension and stress, leaving your muscles relaxed for up to 45 minutes after.
  • Laughter boosts the immune system. Laughter decreases stress hormones and increases immune cells and infection-fighting antibodies, thus improving your resistance to disease.
  • Laughter triggers the release of endorphins, the body’s natural feel-good chemicals. Endorphins promote an overall sense of well-being and can even temporarily relieve pain.
  • Laughter protects the heart. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems.
