Unul dintre principalii factori este un compus chimic numit 2-nonenal, relateaz\u0103 The Guardian<\/a>, \u00eentr-un articol care reune\u0219te explica\u021biile mai multor speciali\u0219ti \u0219i rezultatele unor cercet\u0103ri \u00een domeniu.<\/p>\n

De unde provine mirosul asociat \u00eenaint\u0103rii \u00een v\u00e2rst\u0103<\/h2>\n

Pielea este acoperit\u0103 de un strat fin de lipide naturale, cu rol \u00een men\u021binerea hidrat\u0103rii \u0219i protejarea acesteia. Compozi\u021bia acizilor gra\u0219i din aceste lipide se modific\u0103 \u00eens\u0103 odat\u0103 cu v\u00e2rsta, \u00een timp ce mecanismele prin care pielea face fa\u021b\u0103 agresiunilor cotidiene devin mai pu\u021bin eficiente.<\/p>\n

\u00cen urma oxid\u0103rii \u0219i degrad\u0103rii acestor uleiuri naturale se formeaz\u0103 2-nonenalul, compus asociat mirosului specific observat la unele persoane mai \u00een v\u00e2rst\u0103.<\/p>\n

Dermatologul Roya Javid subliniaz\u0103 c\u0103 procesul reprezint\u0103 un efect natural al \u00eemb\u0103tr\u00e2nirii pielii, nu o consecin\u021b\u0103 a murd\u0103riei sau a lipsei de igien\u0103. Cantitatea de 2-nonenal difer\u0103 \u00eens\u0103 de la o persoan\u0103 la alta, iar genetica, microbiomul pielii, starea de s\u0103n\u0103tate, mediul, hainele \u0219i obiceiurile de igien\u0103 ar putea influen\u021ba intensitatea mirosului.<\/p>\n

Modific\u0103rile pot \u00eencepe \u00een jurul v\u00e2rstei de 40 de ani<\/h2>\n

Fenomenul ar putea debuta mai devreme dec\u00e2t sugereaz\u0103 stereotipurile asociate v\u00e2rstei \u00eenaintate.<\/p>\n

Un studiu japonez din 2001, realizat pe persoane cu v\u00e2rste \u00eentre 26 \u0219i 75 de ani, a detectat 2-nonenal \u00eencep\u00e2nd de la aproximativ 40 de ani. Speciali\u0219tii avertizeaz\u0103 \u00eens\u0103 c\u0103 acest prag nu trebuie interpretat ca o schimbare brusc\u0103 a mirosului corporal.<\/p>\n

Medicul Arshad Rather explic\u0103 faptul c\u0103 nivelul compusului cre\u0219te treptat odat\u0103 cu \u00eenaintarea \u00een v\u00e2rst\u0103, \u00een special dup\u0103 v\u00e2rsta mijlocie.<\/p>\n

Studiu: mirosul persoanelor v\u00e2rstnice nu a fost considerat cel mai nepl\u0103cut<\/h2>\n

Interesant este c\u0103 percep\u021bia negativ\u0103 asociat\u0103 a\u0219a-numitului \u201emiros de b\u0103tr\u00e2ne\u021be\u201d nu este confirmat\u0103 neap\u0103rat de experimente.<\/p>\n

\u00centr-un studiu din 2012, 41 de adul\u021bi tineri au evaluat mirosul unor tricouri purtate de persoane din trei categorii de v\u00e2rst\u0103: 20-30 de ani, 45-55 de ani \u0219i 75-95 de ani.<\/p>\n

Mirosul provenit de la participan\u021bii cei mai v\u00e2rstnici a fost evaluat drept mai pu\u021bin intens \u0219i mai pu\u021bin nepl\u0103cut dec\u00e2t cel al celorlalte grupe. Cercet\u0103torii au constatat, totu\u0219i, c\u0103 persoanele \u00een v\u00e2rst\u0103 au un profil olfactiv distinct.<\/p>\n

Poate fi eliminat 2-nonenalul?<\/h2>\n

Exper\u021bii spun c\u0103 formarea compusului nu poate fi oprit\u0103 complet. Sp\u0103larea regulat\u0103 poate reduce mirosul, \u00eens\u0103 apa \u0219i s\u0103punul nu elimin\u0103 \u00een totalitate 2-nonenalul, deoarece acesta este produs continuu prin procesele care au loc la nivelul pielii.<\/p>\n

Sp\u0103larea hainelor \u0219i a lenjeriei \u0219i aerisirea \u00eenc\u0103perilor pot contribui, de asemenea, la diminuarea mirosului. \u00cen cazul produselor promovate special pentru neutralizarea 2-nonenalului, speciali\u0219tii atrag aten\u021bia c\u0103 dovezile \u0219tiin\u021bifice privind eficien\u021ba lor sunt, deocamdat\u0103, insuficiente.<\/p>\n","protected":false},"excerpt":{"rendered":"
