Gåsehud

Dessverre er det sånn at jeg glemmer det meste jeg tenker på å skrive om når jeg ikke er i nærheten av Macen, men kommer på en ting fra spinnigtimen min går som må skrives ned...

Jeg hadde helt ny spilleliste, med bla. Darkside med Nicolas Jaar. Den er lang, nesten 7 minutter, og jeg improviserer bare hva vi gjør på sykkelen underveis. Det blir faktisk meditativt og jeg kommer nesten i en mild transe underveis. Musikken er bare helt fantastisk og plutselig fikk jeg den "sterkeste" gåsehuden jeg noengang har følt. Alle har reiste seg fra leggene opp til nakkehårene mine. Det var sikkert 35 grader varmt i rommet oig svetten rant av meg som den aldri har gjort, men det som var det kule da, med denne gåsehuden var et jeg kjente at jeg ble kjølt ned på hele kroppen. Rett og slette en sterk opplevelse og føle åssen kroppen min jobber for å ta vare på seg selv. Jeg ble altså nesten kald på armene når jeg fikk denne gåsehuden. Det var heftig....

Jeg har alltid trodd/hørt at gåsehud får man mest når man fryser og selvsagt når man får gode/sterke opplevelser på det mentale plan. Når man fryser så reiser hårene seg for å isolere (luft isolerer jo), men det stemmer ikke helt med min opplevelse i går. Jeg søkte opp goosebumps på Wolfram:

Goose bumps, also called goose flesh, goose pimples, the medical term cutis anserina, are the bumps on a person's skin at the base of body hairs which may involuntarily develop when a person is cold or experiences strong emotions such as fear, nostalgia, pleasure, euphoria, awe, admiration and sexual arousal.[1]

The formation of goose bumps in humans under stress is a vestigial reflex[2]; its function in human ancestors was to raise the body's hair, making the ancestor appear larger and scaring off predators. The reflex of producing goose bumps is known as arasing, piloerection, or the pilomotor reflex. It occurs in many mammals besides humans; a prominent example is porcupines, which raise their quills when threatened, or sea otters when they encounter sharks or other predators.

The phrase "goose bumps" derives from the phenomenon's association with goose skin. Goose feathers grow from stores in the epidermis which resemble human hair follicles. When a goose's feathers are plucked, its skin has protrusions where the feathers were, and these bumps are what the human phenomenon resembles.

It is not clear why the particular fowl, goose, was chosen in English, as most other birds share this same anatomical feature. Some authors have applied "goose bumps" to the symptoms of sexually-transmitted diseases.[3] Certainly being "bitten by a Winchester goose" was a common euphemism for syphilis[4] in the 16th century.[5] "Winchester geese" was the nickname for the prostitutes of South London,[6] licenced by the Bishop of Winchester in the area around his London palace.

Goose bumps can be experienced in the presence of cold temperatures. The stimulus of cold surroundings causes the tiny muscles attached to each hair follicle to contract. This contraction causes the hair strands to literally "stand on end." At the same time, the tiny muscles that are contracting are causing a "bunching" of the skin surrounding the hairs, which results in the "bumps" in goose bumps.

This is the body's way of preserving its own heat by causing the hairs on the skin to stand up, thus reducing heat loss. Goose bumps are often seen in conjunction with shivering in these instances.

Cause

People also get goose bumps when they are hot, or in the presence of extreme heat. The main reason for this is sweat. As the perspiration accumulates on the skin, it naturally evaporates. As the sweat evaporates, it cools down the skin surface. As this process occurs, a dramatic temperature difference occurs and the body responds to the "chill" of the evaporation of the sweat and the "goose bump response" kicks in.[13]

Intense emotion

People often say they feel their "hair standing on end" when they are frightened or in awe. Another intense emotional situation that can cause goose bumps is the "fight or flight" response the body can employ in an extremely stressful situation. As the body prepares itself for either fighting or running, the sympathetic nervous system floods the blood with adrenaline (epinephrine), a hormone that speeds up heart rate,metabolism, and body temperature in the presence of extreme stress. The sympathetic nervous system also causes a reflex called piloerection, which makes the muscles attached to the base of each hair follicle contract and force the hair up. Goose bumps cause the hairs to stand up, just as porcupines raise their quills when threatened.
