Po\u010das pand\u00e9mie koronav\u00edrusu n\u00e1\u0161 fyzick\u00fd kontakt nahradil digit\u00e1lny svet.

\u010eal\u0161ou obavou je potenci\u00e1lny vplyv modr\u00e9ho svetla na na\u0161e o\u010di<\/strong>. Jeho dlhodob\u00e9 p\u00f4sobenie m\u00f4\u017ee vies\u0165 k digit\u00e1lnej \u00fanave o\u010d\u00ed<\/strong>, \u010do je s\u00fabor o\u010dn\u00fdch probl\u00e9mov, ako s\u00fa neust\u00e1le such\u00e9, unaven\u00e9 a\u00a0nap\u00e4t\u00e9 o\u010di.

Ako to vidia vedci a s\u00fa\u010dasn\u00e9 v\u00fdskumy?<\/h3>\n

V\u00a0s\u00fa\u010dasnosti neexistuje takmer \u017eiadny d\u00f4kaz o\u00a0tom, \u017ee by bol d\u00f4vod na obavy. Existuj\u00fa s\u00edce \u0161t\u00fadie, ktor\u00e9 by mohli podporova\u0165 my\u0161lienku, \u017ee n\u00e1m modr\u00e9 svetlo \u0161kod\u00ed, nemo\u017eno ich v\u0161ak pova\u017eova\u0165 sa \u00faplne relevantn\u00e9. Jednou z\u00a0nich je napr\u00edklad \u0161t\u00fadia na potkanoch, ktor\u00e1 uk\u00e1zala, \u017ee modr\u00e9 svetlo m\u00f4\u017ee po\u0161kodi\u0165 bunky sietnice<\/strong>.<\/p>\n

\u0160t\u00fadie sa realizovali \u201ein vitro<\/em>\u201c, \u010di\u017ee mimo prostredia, v\u00a0ktorom sa nie\u010do prirodzene nach\u00e1dza. Potkany s\u00fa no\u010dn\u00e9 tvory a nemusia reagova\u0165 na modr\u00e9 svetlo rovnako ako \u013eudia. \u0160t\u00fadie na \u013eu\u010foch za realistick\u00fdch podmienok v podstate neexistuj\u00fa<\/strong>, preto\u017ee pou\u017e\u00edvanie LED je relat\u00edvne nov\u00e9. Lek\u00e1ri v s\u00fa\u010dasnosti nevidia ve\u013ea d\u00f4vodov na znepokojenie.<\/p>\n

A\u00a0ako to je teda so sp\u00e1nkom? Tu sa objavuj\u00fa o nie\u010do lep\u0161ie d\u00f4kazy na zv\u00e1\u017eenie. Je zn\u00e1me, \u017ee modr\u00e9 svetlo zvy\u0161uje bdelos\u0165 a za ur\u010dit\u00fdch okolnost\u00ed m\u00f4\u017ee zlep\u0161i\u0165 kognit\u00edvne funkcie, najm\u00e4 po\u010das d\u0148a, ke\u010f je dobr\u00e9 by\u0165 v strehu. Existuj\u00fa aj ur\u010dit\u00e9 d\u00f4kazy, \u017ee potl\u00e1\u010da melaton\u00edn, no pr\u00e1ve tu sa m\u00f4\u017eu vkradn\u00fa\u0165 nedorozumenia.<\/p>\n

According to Russella G. Fostera<\/strong>, profesora cirkadi\u00e1lnej neurovedy na Oxfordskej univerzite, melaton\u00edn nie je sp\u00e1nkov\u00fd horm\u00f3n, ale len ve\u013emi mierny modul\u00e1tor sp\u00e1nku<\/strong>. Neexistuje pod\u013ea neho \u017eiadny d\u00f4kaz, \u017ee napr\u00edklad pou\u017e\u00edvanie filtrov modr\u00e9ho svetla na va\u0161om po\u010d\u00edta\u010di m\u00e1 nejak\u00fd vplyv na cirkadi\u00e1nny syst\u00e9m.<\/p>\n

V\u00fdskumn\u00edci vykonali \u0161t\u00fadiu, kde sa dobrovo\u013en\u00edci pozerali na elektronick\u00fa \u010d\u00edta\u010dku pri najvy\u0161\u0161om jase \u0161tyri hodiny, bezprostredne pred span\u00edm. Urobili to p\u00e4\u0165 po sebe id\u00facich noc\u00ed, na konci ktor\u00fdch bol melaton\u00edn potla\u010den\u00fd, no sp\u00e1nok sa oneskoril len o 10 min\u00fat. Pod\u013ea Fostera to m\u00f4\u017ee by\u0165 \u0161tatisticky v\u00fdznamn\u00e9, no biologicky nezmyseln\u00e9. Elektronick\u00e1 \u010d\u00edta\u010dka jednoducho nemala takmer \u017eiadny vplyv na sp\u00e1nok. M\u00f4\u017ee tu v\u0161ak vznika\u0165 aj ot\u00e1zka, ak\u00e9 by tento v\u00fdskum nadobudol v\u00fdsledky, keby sa konal dlh\u0161ie ako len p\u00e4\u0165 noc\u00ed po sebe.<\/p>\n

V\u00a0roku 2019 vznikli aj \u010fal\u0161ie \u0161t\u00fadie, ktor\u00e9 nazna\u010duj\u00fa, \u017ee naru\u0161enie cyklu sp\u00e1nku a bdenia sp\u00f4soben\u00e9 svetlom m\u00f4\u017ee sp\u00f4sobi\u0165 n\u00e1ladovos\u0165 alebo metabolick\u00e9 naru\u0161enie<\/strong>. Hovor\u00edme v\u0161ak o\u00a0vystavovan\u00ed sa svetlu vo v\u0161eobecnosti, nejde teda konkr\u00e9tne o\u00a0modr\u00e9 svetlo.<\/p>\n

    \n
  1. Pou\u017e\u00edvajte filtre modr\u00e9ho svetla priamo na svojich elektronick\u00fdch zariadeniach<\/strong>, najm\u00e4 ve\u010der, aby ste minimalizovali jeho vplyv na v\u00e1\u0161 sp\u00e1nok;<\/li>\n
  2. Nezab\u00fadajte na odpo\u010dinok a\u00a0robte si pravideln\u00e9 prest\u00e1vky pri dlhodobom pou\u017e\u00edvan\u00ed elektronick\u00e9ho zariadenia.<\/strong> Upierajte o\u010di na vzdialen\u00e9 objekty, aby ste predi\u0161li \u00fanave o\u010d\u00ed;<\/li>\n
  3. Starostlivo zva\u017eujte osvetlenie vo va\u0161om interi\u00e9ri. V\u00fdber teplej\u0161\u00edch farieb a\u00a0tlmen\u00e9 osvetlenie m\u00f4\u017ee pom\u00f4c\u0165 minimalizova\u0165 p\u00f4sobenie modr\u00e9ho svetla<\/strong>;<\/li>\n
  4. Dodr\u017eiavajte zdrav\u00fd sp\u00e1nkov\u00fd re\u017eim a obmedzujte pou\u017e\u00edvanie elektronick\u00fdch zariaden\u00ed pred sp\u00e1nkom<\/strong>.<\/li>\n<\/ol>\n
