Laughter is simply an extension of this process,
Blushing occurs when cerebral blood flow is channelled through the facial artery
Laughter is a similar kind of release, say Marijuán and Navarro. The intellectual momentum that builds up during conversation needs to be relieved, either through verbalisation or some other mechanism.
channelling of excess cortical excitations to parts of the brain responsible for vocalisation. But without anything specific to say, the result is the kind of panting and cackling that we call laughter.
Laughter has to do with surprise. Steve Martin the comedian said that. I believe the early hunter-gatherers ran into one another and surprised one another. Laughter became the way to relieve the tension and let each know it was okay
gang members. The first one to laugh is considered incompetent and is marked as an easy kill.

Laughter is a reaction to something unexpected (but not threatening) and in this sense it's a "relief" only insofar as it's an instantaneous reaction.
It's why we can laugh at something immediate (like someone suddenly falling over) as well as set-up and why knowing the punchline typically makes it less funny.
As to the evolution it's really a toss-up, for one it provides a boost of dopamine which could provide health benefits for the person laughing and others as well.
The irony of Marijuán and Navarro's hypothesis is that genuine laughter is negatively correlated with social situations. Studies of autistic children show that the overwhelming majority of laughs are genuine "voiced" laughs (half of the autistic children could only do genuine laughs) while non-autistic children are more likely to fake laughter.
Other than a healthy release to non-threating unexpected events, there's not much else that can explain laughter.
laughter is an expression of relief
Monks who have taken vows of silence will express their approval or laughter by holding one hand in a semi-closed position and clapping against it with the other - it sounds curiously like laughter.
Every comedian knows that you have to set up some degree of either conflict or miss-direction first - this indicates that laughter is a sort of relief even when the 'conflict' was unanticipated.
Laughter upon tickle can be seen as a relief of the conflict of "is this going to hurt?"
