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 fleshgoose pimplesstill bumpschicken skinDasler Bumpschicken bumpspeople humps, or the medical term kutis ansterina, 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 fearnostalgiapleasureawe, admiration and sexual arousal.[1]

The reflex of producing goose bumps is known as horripilationpiloerection, 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.

Other creatures get goose bumps for the same reason, for example this is why a cat or dog’s hair stands on end and the cause behind a porcupine’s quills raising. In cold situations, the rising hair traps air between the hairs and skin, creating insulation and warmth. In response to fear, goose bumps make an animal appear larger – hopefully scaring away the enemy.

 

Goosebumps 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 goosebumps.

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. Goosebumps are often seen in conjunction with shivering in these instances.

People also get goosebumps 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 "goosebump response" kicks in.

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 goosebumps 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 ratemetabolism, 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. When piloerection occurred in man's ancestors, their plentiful hair made them appear larger to enemies and helped keep them warm. Although man is no longer as hairy, the reflex remains.[11]

Music

Canadian researchers have suggested that when we are moved by music our brains behave as if reacting to delicious food, psychoactive drugs, or money. According to Caribbean Sociologist, Corey Alexander Lane, "The reaction from music is based on the memory induced emotion that some songs create." In the practice of music production this phenomenon has long been used to judge the quality and impact of a performance, particularly in recording studios during the playback process. The engineers and producers

 

would say "You knew something was good if it gave you goose bumps." They would actually roll up their sleeves and visually check their arms.

The pleasure experience is driven by the chemical dopamine, which has been linked to addiction. It produces physical effects known as "chills" that cause changes in the skin's electrical conductance, heart rate, breathing and temperature. The responses correlate with the degree to which people rate the "pleasurability" of music.

The new research has shown that dopamine release was greatest when listeners had a strong emotional response to music. "If music-induced emotional states can lead to dopamine release, as our findings indicate, it may begin to explain why musical experiences are so valued,” wrote the scientists.[12]
