Bizi ka\u015f\u0131nmaya iten o rahats\u0131z edici his olan ka\u015f\u0131nt\u0131, kendisine ayr\u0131lm\u0131\u015f bir dizi sinir yoluyla iletilen karma\u015f\u0131k bir olgudur.

Ka\u015f\u0131nt\u0131y\u0131 ka\u015f\u0131mak ge\u00e7ici bir rahatlama sa\u011flayabilir, ancak uzun vadede ka\u015f\u0131nt\u0131y\u0131 daha da k\u00f6t\u00fcle\u015ftirebilir. Bunun nedeni, ka\u015f\u0131man\u0131n bir s\u00fcreli\u011fine ka\u015f\u0131nt\u0131 hissini bast\u0131ran a\u011fr\u0131ya neden olmas\u0131d\u0131r.
