Laughing is a reaction to certain stimuli. Traditionally, it is considered a visual expression of happiness, or an inward feeling of joy. It may ensue from hearing a joke, being tickled, or other stimuli. Laughter is used as a signal for being part of a group — it signals acceptance and positive interactions with others.

Laughter

Laughter is the sun that drives winter from the human face. -Victor Hugo

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.

Laughter is sometimes seen as contagious, and the laughter of one person can itself provoke laughter from others as a positive feedback.

Laughter is anatomically caused by the epiglottis constricting the larynx. The study of humor and laughter, and its psychological and physiological effects on the human body, is called gelotology.

Children are known to laugh a great deal more than adults: an average baby laughs around 300 times a day compared to an average adult, who laughs around 20 times a day; however this can depend on a person's personality.

Researchers have shown infants as early as 17 days old have vocal laughing sounds or laughter.

Laughter researcher Robert Provine said: "Laughter is a mechanism everyone has; laughter is part of universal human vocabulary. There are thousands of languages, hundreds of thousands of dialects, but everyone speaks laughter in pretty much the same way.”

Nature of laughter

There are many types of laughter ranging from giggling to cackles. Pigeon LaughterThis type of laughter is in the giggle range. When ones laughs a pigeon laugh

is a giggle with the lips closed.Etiquette LaughterThis laugh is used when laughing at someone's joke that you don't understand

or don't find funny. It is usually a polite laugh.Sniggering LaughterThis laugh is more of an underhanded laugh. This is used generally by

someone making fun of or taking delight in another's discomfort.Silent LaughterA smile is considered a silent laugh. It is as beneficial as a ‘laugh out loud’

laugh. The only difference is that one is noisy the other is silent.

Types of laughter

Chuckling LaughterIt is a good natured laugh somewhere in-between a silent laugh and a

belly laugh. A person who chuckles is thought of as kind and thoughtful.

Nervous LaughterThis laughter shows our stress and nervousness. Unfortunately it also

generally makes the situation worse.

Belly LaughterThis is the most honest of all the types of laughter. There is no way to fake it.

You open your mouth and out it comes. Many times it leaves the person holding their sides gasping for air.

Cackling LaughterThis type of laughter is openly disdainful and disrespectful. It is generally

overly loud with a shriek thrown in occasionally. The person who uses this type of laugh is opening taking pleasure in someone else's pain and discomfort.

Snort LaughterThis laugh is used by someone who thinks they are better than the ones

around them. This way they show their disapproval or little interest in other person’s opinion.

laugh. • Keep a journal of the things that make you laugh or amuse you. Whenever

your are down you can read the list and give yourself a lift.• Start a happy conversation with a friend. Talk about funny or amusing

things.• Spend most of your time with people who make you laugh.• Surround yourself with funny pictures, stories quotes, and cartoons.• Learn to play. You'll be surprised at how easy it is to laugh when you are

being playful.

• Laughter Yoga (Hasyayoga) is a form of yoga employing self-triggered laughter. The concept of Laughter Yoga is based on the scientific observation that the body cannot differentiate between fake and real laughter, and that both provide the same physiological and psychological benefits. Laughter Yoga combines unconditional laughter with pranayama (yogic breathing). Laughter is simulated as a body exercise in a group; with eye contact and childlike playfulness, initially forced laughter soon turns into real and contagious laughter. The "laughter" is physical in nature, and does not necessarily involve humor or comedy.

• Laughter yoga was made popular as an exercise routine developed by Indian physician Madan Kataria. Kataria's first Laughter Yoga Club began on 13 March 1995 in Mumbai; beginning with five people in a local public park, the concept has rapidly spread worldwide. As of 2011, there are more than 8,000 Laughter Clubs in 65 countries. Each club has its own Laugh Captain and operates as an independent cell.

Laughter - The best Medicine

A normal laugh has the structure of “ha-ha-ha” or “ho-ho-ho.”

It has also been determined that eyes moisten during laughter as a reflex from the tear glands.
