Jedn\u00edm z hlavn\u00edch d\u016fvod\u016f je reakce nervov\u00e9ho syst\u00e9mu na n\u00e1hl\u00fd chlad. Jakmile se studen\u00e1 voda dotkne poko\u017eky, aktivuj\u00ed se teplotn\u00ed receptory, kter\u00e9 okam\u017eit\u011b vys\u00edlaj\u00ed sign\u00e1ly do mozku.

Pr\u00e1v\u011b noradrenalin je jednou z nejv\u00edce zkouman\u00fdch l\u00e1tek v souvislosti se studenou vodou. Klasick\u00e1 studie publikovan\u00e1 <\/a>v \u010dasopise European Journal of Applied Physiology zjistila, \u017ee dlouhodob\u011bj\u0161\u00ed pobyt ve vod\u011b o teplot\u011b 14 \u00b0C vedl k v\u00fdrazn\u00e9mu zv\u00fd\u0161en\u00ed hladiny noradrenalinu a sou\u010dasn\u011b i ke zv\u00fd\u0161en\u00ed energetick\u00e9ho v\u00fddeje.<\/p>\n

Je v\u0161ak d\u016fle\u017eit\u00e9 zd\u016fraznit, \u017ee tato studie nezkoumala dvouminutovou sprchu, ale p\u0159ibli\u017en\u011b hodinovou imerzi ve studen\u00e9 vod\u011b.

Pr\u00e1v\u011b proto \u0159ada odborn\u00edk\u016f doporu\u010duje za\u0159adit studenou vodu na z\u00e1v\u011br b\u011b\u017en\u00e9ho sprchov\u00e1n\u00ed.

Noradrenalin toti\u017e pat\u0159\u00ed mezi kl\u00ed\u010dov\u00e9 l\u00e1tky, kter\u00e9 mozek vyu\u017e\u00edv\u00e1 p\u0159i soust\u0159ed\u011bn\u00ed a rychl\u00e9 reakci na okoln\u00ed podn\u011bty.

Mechanismus je sice \u010d\u00e1ste\u010dn\u011b podobn\u00fd, \u00fa\u010dinky jsou v\u0161ak nesrovnateln\u00e9 a l\u00e9ka\u0159sk\u00e1 l\u00e9\u010dba m\u00e1 zcela jin\u00e9 vyu\u017eit\u00ed.<\/p>\n

V\u00fdzkumn\u00edci z\u00e1rove\u0148 zkoumaj\u00ed vliv chladu na n\u00e1ladu. N\u011bkolik studi\u00ed nazna\u010duje<\/a>, \u017ee po kr\u00e1tk\u00e9 studen\u00e9 koupeli doch\u00e1z\u00ed ke zlep\u0161en\u00ed subjektivn\u00edho pocitu pohody a sn\u00ed\u017een\u00ed negativn\u00edch emoc\u00ed.

Velkou pozornost z\u00edsk\u00e1v\u00e1 tak\u00e9 vliv na metabolismus. Kdy\u017e t\u011blo za\u010dne poci\u0165ovat chlad, mus\u00ed vyr\u00e1b\u011bt teplo. Do procesu se zapojuje takzvan\u00e1 hn\u011bd\u00e1 tukov\u00e1 tk\u00e1\u0148, kter\u00e1 m\u00edsto ukl\u00e1d\u00e1n\u00ed energie kalorie spaluje. Systematick\u00e1 anal\u00fdza publikovan\u00e1 <\/a>ve Frontiers in Physiology potvrzuje, \u017ee akutn\u00ed vystaven\u00ed chladu zvy\u0161uje energetick\u00fd v\u00fddej a aktivitu hn\u011bd\u00e9 tukov\u00e9 tk\u00e1n\u011b.\u00a0<\/p>\n

To ale neznamen\u00e1, \u017ee studen\u00e1 sprcha sama o sob\u011b p\u0159edstavuje z\u00e1zra\u010dn\u00fd prost\u0159edek na hubnut\u00ed. Zv\u00fd\u0161en\u00fd energetick\u00fd v\u00fddej je ve srovn\u00e1n\u00ed s dlouhodob\u00fdm kalorick\u00fdm deficitem pom\u011brn\u011b mal\u00fd.

Dal\u0161\u00edm \u010dasto zmi\u0148ovan\u00fdm benefitem je regenerace po sportovn\u00edm v\u00fdkonu. Pr\u00e1v\u011b proto jsou ledov\u00e9 koupele b\u011b\u017enou sou\u010d\u00e1st\u00ed profesion\u00e1ln\u00edho sportu. Sportovci je vyu\u017e\u00edvaj\u00ed p\u0159edev\u0161\u00edm ke zm\u00edrn\u011bn\u00ed bolesti sval\u016f a rychlej\u0161\u00edmu zotaven\u00ed po n\u00e1ro\u010dn\u00fdch z\u00e1pasech nebo tr\u00e9ninc\u00edch.<\/p>\n

Ani zde ale nen\u00ed situace \u00fapln\u011b \u010dernob\u00edl\u00e1. P\u0159ehledov\u00e9 studie <\/a>potvrzuj\u00ed, \u017ee studen\u00e1 voda m\u016f\u017ee kr\u00e1tkodob\u011b zm\u00edrnit bolestivost sval\u016f a n\u011bkter\u00e9 zn\u00e1mky z\u00e1n\u011btu, sou\u010dasn\u011b v\u0161ak existuj\u00ed d\u016fkazy, \u017ee pravideln\u00e9 ledov\u00e9 koupele bezprost\u0159edn\u011b po silov\u00e9m tr\u00e9ninku mohou m\u00edrn\u011b omezovat r\u016fst svalov\u00e9 hmoty.<\/p>\n

Zaj\u00edmav\u00fdm t\u00e9matem je tak\u00e9 odolnost v\u016f\u010di stresu. Pravideln\u00e9 vystavov\u00e1n\u00ed organismu kontrolovan\u00e9mu chladu p\u0159edstavuje formu takzvan\u00e9ho hormetick\u00e9ho stresu. Jde o kr\u00e1tkodobou z\u00e1t\u011b\u017e, kter\u00e1 m\u016f\u017ee organismus postupn\u011b u\u010dit efektivn\u011bji reagovat na nep\u0159\u00edjemn\u00e9 situace.

Pokud chce n\u011bkdo studenou sprchu vyzkou\u0161et, nen\u00ed pot\u0159eba za\u010d\u00ednat extr\u00e9mn\u011b.

Postupn\u011b lze d\u00e9lku prodlu\u017eovat podle individu\u00e1ln\u00ed tolerance.<\/p>\n
