Mechanismus p\u016fsoben\u00ed kofeinu na sp\u00e1nek<\/h3>\n

Kofein p\u016fsob\u00ed jako antagonista adenosinu, neurotransmiteru, kter\u00fd se pod\u00edl\u00ed na regulaci bd\u011blosti a sp\u00e1nku. Adenosin se v pr\u016fb\u011bhu dne kumuluje v mozku a zp\u016fsobuje \u00fanavu. Kofein blokuje jeho receptory, \u010d\u00edm\u017e br\u00e1n\u00ed jeho \u00fa\u010dink\u016fm a prodlou\u017euje dobu bd\u011blosti. Tento efekt je v\u0161ak do\u010dasn\u00fd a m\u016f\u017ee v\u00e9st k n\u00e1sledk\u016fm v noci. Doba, za kterou se kofein z t\u011bla vylou\u010d\u00ed, se li\u0161\u00ed od \u010dlov\u011bka k \u010dlov\u011bku, ale obecn\u011b se pohybuje v rozmez\u00ed 5-6 hodin.
