A cheerful heart is a good medicine, but a downcast spirit dries up the bones.
Proverbs 17: 
Although scientific evidence does not yet support laughter as an effective treatment for disease, researchers have shown that laughter has many physical, emotional, and social benefits.
Physical Benefits of Laughter
Laughter can be aerobic. As you laugh, muscles contract and then relax. Blood pressure drops. Breathing becomes deeper.
A hearty laugh can give your abdomen, diaphragm, heart, lungs, and thorax a good workout.
Laughter causes the release of endorphins, which are special neurotransmitter substances in the brain that help control pain.
Emotional Benefits of Laughter
Laughter can sweep away stored negative emotions, such as anger, fear, and sadness.
Laughter can relieve stress, giving you a new perspective and helping you to renew your spirits.
Laughter strengthens your resilience. Laughing can remind you that no one is perfect. Even when you do something silly, laughter can help you to bounce back into a positive mood.
Social Benefits of Laughter
Laughter enhances personal relationships. Laughter boosts morale, engenders closeness between mates, and promotes feelings of self-worth.
Laughter diffuses conflict in working relationships. You can use laughter to develop a camaraderie and power in difficult situations.
Sharing laughter with someone you trust or respect provides hope, and can lead to new ways of viewing and managing life’s everyday challenges.
Four Tips for Healthy Laughter
Smile at people when you walk for exercise or pleasure, to show you are friendly and accepting of them, whoever they are. Smiling demonstrates mutual respect and can spark laughter.
Let children teach you. As children play, they are completely focused on laughing, as their kite takes flight, or as their pet dog jumps into the air for tennis-ball fetch. Learn to focus on playful thoughts, which lead to laughter.
Seek out light-hearted persons to share mutually enjoyable activities. Fun leads to laughter and to fresh ways of seeing the world around you.
Remind yourself that, where your health is concerned, laughter is contagious!
