Americk\u00e1 studie dokl\u00e1d\u00e1, \u017ee u\u017e t\u00fddenn\u00ed dovolen\u00e1 v kempinku \u0159e\u0161\u00ed sp\u00e1nkov\u00e9 probl\u00e9my. V odborn\u00e9m \u010dasopise Current Biology to vysv\u011btluj\u00ed t\u00edm, \u017ee „slune\u010dn\u00ed osv\u011btlen\u00ed l\u00e9pe zapad\u00e1 do vnit\u0159n\u00edch hodin \u010dlov\u011bka pro rytmus den a noc“.<\/p>\n

T\u00fdm Kennethe Wrighta z Coloradsk\u00e9 univerzity v Boulderu sledoval nejd\u0159\u00edve\u00a0 rytmus no\u010dn\u00edho sp\u00e1nku dosp\u011bl\u00fdch, kte\u0159\u00ed chod\u00edvali na kut\u011b po p\u016flnoci a pozd\u011bji vst\u00e1vali.<\/p>\n

Dal\u0161\u00ed t\u00fdden str\u00e1vila cel\u00e1 parta ve Skalnat\u00fdch hor\u00e1ch. Nevyu\u017e\u00edvali p\u0159i tom um\u011bl\u00e9 sv\u011btlo a nesm\u011bli m\u00edt u sebe ani mobily, baterky apod.<\/p>\n

N\u00e1sledky pak p\u0159ekvapily: zjistilo se, \u017ee v um\u011ble osv\u011btlen\u00e9m okol\u00ed \u0161ly vnit\u0159n\u00ed hodiny \u00fa\u010dastn\u00edk\u016f o dv\u011b hodiny pozd\u011bji \u2013 p\u0159i pobytu v p\u0159\u00edrod\u011b se jejich vnit\u0159n\u00ed \u010das vr\u00e1til do norm\u00e1ln\u00edch kolej\u00ed.Prok\u00e1zala to koncetrace hormonu melatonin, kter\u00fd se v t\u011ble pod\u00edl\u00ed na regulaci rytmu den a noc.<\/p>\n

To vysv\u011btluje, pro\u010d mnoho lid\u00ed – pozdn\u00edch sp\u00e1\u010d\u016f – se v modern\u00edm sv\u011bt\u011b r\u00e1no c\u00edt\u00ed mal\u00e1tn\u00fdmi a unaven\u00fdmi. Biologick\u00e1 noc, charakterizovan\u00e1 vy\u0161\u0161\u00ed hladinou melatoninu, toti\u017e p\u0159etrv\u00e1v\u00e1 a\u017e do dne.<\/p>\n

N\u011bmeck\u00fd list Die Welt k tomu napsal, \u017ee po t\u00fddnu kempov\u00e1n\u00ed se vnit\u0159n\u00ed hodiny lid\u00ed p\u0159izp\u016fsobily p\u0159irozen\u00e9mu rytmu. Melatonin za\u010dal stoupat po z\u00e1padu slunce a r\u00e1no spadl z\u00e1rove\u0148 s v\u00fdchodem slunce, tedy p\u0159ed probuzen\u00edm.<\/p>\n

Celkov\u00e1 d\u00e9lka sp\u00e1nku z\u016fstala stejn\u00e1, ale p\u0159izp\u016fsoben\u00ed se p\u0159irozen\u00e9mu rytmu vedlo ke zdrav\u011bj\u0161\u00edmu sp\u00e1nku, m\u00edn\u00ed experti.<\/p>\n

Vzhledem k tomu, \u017ee ne v\u0161ichni lid\u00e9 mohou j\u00edt kempovat, rad\u00ed jim v\u011bdci: sna\u017ete se b\u00fdt p\u0159es den co nejd\u00e9le na slune\u010dn\u00edm sv\u011btle (t\u00edm se nemysl\u00ed pob\u00fdvat na p\u0159\u00edm\u00e9m slunci, ale vyu\u017e\u00edvat p\u0159irozen\u00e9ho denn\u00edho sv\u011btla jak p\u0159i pr\u00e1ci, tak p\u0159i volno\u010dasov\u00fdch aktivit\u00e1ch) a ve\u010der co nejm\u00e9n\u011b pod elektrickou lampou.<\/p>\n

T\u00edm se v\u00e1m poda\u0159\u00ed dostat do souladu dobu sp\u00e1nku a dobu studia \u010di pr\u00e1ce.<\/p>\n

Slune\u010dn\u00ed sv\u011btlo ale tak\u00e9 sni\u017euje mno\u017estv\u00ed sebevra\u017ed<\/strong><\/p>\n

T\u0159\u00ed\u010dlenn\u00fd t\u00fdm japonsk\u00fdch odborn\u00edk\u016f z Kyoto University zjistil spojitost mezi sebevra\u017eedn\u00fdmi pokusy a mno\u017estv\u00edm slune\u010dn\u00edho sv\u011btla. V\u00fdsledky jejich studie publikoval l\u00e9ka\u0159sk\u00fd \u010dasopis Journal of Affective Disorders.<\/p>\n

Auto\u0159i pozorovali zv\u00fd\u0161en\u00fd pod\u00edl sebevra\u017eedn\u00fdch pokus\u016f po n\u011bkolika dnech bez slune\u010dn\u00edho sv\u011btla.<\/p>\n
