Laughing is a reaction to certain stimuli, fundamentally stress, which serves as an emotional balancing mechanism. Traditionally, it's considered a visual expression of happiness, or an inward feeling of joy. It may ensue from hearing a joke, being tickled, or other stimuli. It is in most cases a very pleasant sensation (Wikipidia).
Common causes for laughter are sensations of joy and humor; however, other situations may cause laughter as well.
Other people, laughing helped them feel better and get some pain-free sleep. That’s because laughter helps the pituitary gland release its own pain-suppressing opiates.
Not everyone really knows what we can gain for every laughter we made.
