Benefits of Laughter

Laughter reduces the level of stress hormones like cortisol, adrenaline, dopamine, and growth hormone. It also increases the level of health-enhancing hormones like endorphins. Laughter increases the number of antibody-producing cells and enhances the effectiveness of T cells. All this means a stronger immune system, as well as fewer physical effects of stress.
 
A good belly laugh exercises the diaphragm, contracts the abs and even works out the shoulders, leaving muscles more relaxed afterward. It even provides a good workout for the heart.
 
Laughter provides distraction and brings focus away from anger, guilt, stress, and negative emotions in a more beneficial way than other distractions.
 
Studies show that our response to stressful events can be altered by whether we view something as a 'threat' or a 'challenge'. Humor can give us a more lighthearted perspective and help us view events as 'challenges', thereby making them less threatening and more positive.
 
Laughter connects us with others. Just as with smiling and kindness, most people find that laughter is contagious, so if you bring more laughter into your life, you can most likely help others around you to laugh more, and realize these benefits as well. By elevating the mood of those around you, you can reduce their stress levels, and perhaps improve the quality of social interaction you experience with them.
