(Redirected from Laughing)

Laughter is a physical reaction in humans and some other species of primate, consisting typically of rhythmical, often audible contractions of the diaphragm and other parts of the respiratory system. It is a response to certain external or internal stimuli.

Etymology[edit | edit source]

The term "laughter" comes from the Old English "hleahtor", which is derived from the Proto-Germanic "hlahtraz". It is associated with the words for "play" and "jump" in many languages.

Types of laughter[edit | edit source]

There are many forms of laughter, including giggling, chuckling, belly laughter, and snorting. Each type of laughter can convey different emotions and have different effects on the body.

Physiology[edit | edit source]

Laughter is a part of human behavior regulated by the brain, helping humans clarify their intentions in social interaction and providing an emotional context to conversations.

Health effects[edit | edit source]

Laughter has been shown to have beneficial health effects, such as reducing stress, boosting the immune system, and enhancing mood.

Laughter in animals[edit | edit source]

Laughter is not exclusive to humans, as many animals also exhibit laughter-like behaviors, often in response to play and tickling.
