Un c\u00edrculo vicioso con base cient\u00edfica. Cr\u00e9dito: Shutterstock.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Rascarse es una de esas peque\u00f1as grandes satisfacciones de la vida. Un mosquito le arruina la noche, pero ah\u00ed est\u00e1 usted, con la u\u00f1a afilada, d\u00e1ndose el gusto. Es un placer primitivo, casi instintivo, que tiene algo de venganza: la picaz\u00f3n lo desaf\u00eda, pero usted gana. \u00bfO no?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sin embargo, la ciencia dice que rascarse es, en realidad, un negocio ruinoso para la piel. La <a href=\"http:\/\/agencia.unq.edu.ar\/?author=7\" target=\"_blank\" rel=\"noopener\" title=\"\">Agencia de Noticias Cient\u00edficas de la Universidad Nacional de Quilmes<\/a>, accedi\u00f3 a un reciente estudio de la<strong> Universidad de Pittsburgh<\/strong>, publicado en la prestigiosa revista <strong>Science<\/strong>, donde se revela que este simple gesto puede convertirse en un boomerang inflamatorio. Es decir,  aunque rascarse puede traer un alivio moment\u00e1neo, en realidad se convierte en su peor enemigo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El experimento es de manual: tomaron ratones, les hicieron una especie de eczema inducido y los dejaron rascarse como locos. Resultado: m\u00e1s inflamaci\u00f3n, m\u00e1s c\u00e9lulas inmunes descontroladas y m\u00e1s da\u00f1o en la piel. Los ratones que no pod\u00edan rascarse\u2014porque les pusieron esos collares tipo &#8220;cono de la verg\u00fcenza&#8221;\u2014se salvaron del desastre.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pero aqu\u00ed viene la paradoja: rascarse tambi\u00e9n tiene un lado positivo. Seg\u00fan explican, rascarse ayuda a eliminar bacterias como el <strong>Staphylococcus aureus<\/strong> , que es el villano n\u00famero uno en infecciones cut\u00e1neas. Entonces, \u00bfes bueno o es malo?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>La clave est\u00e1 en una sustancia llamada &#8220;P&#8221;, que se libera al rascarse y activarse los mastocitos,<\/strong> esas c\u00e9lulas que manejan la inflamaci\u00f3n como si fueran barras bravas en un partido de ascenso. Si la piel ya est\u00e1 irritada, los mastocitos se encienden a\u00fan m\u00e1s, llamando a m\u00e1s c\u00e9lulas inflamatorias y armando un esc\u00e1ndalo en la dermis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O sea, al rascarse se termina\u00a0empeorando todo, pero al mismo tiempo la piel se defiende mejor de las infecciones. Un equilibrio complicado&#8230; \u00bfEntonces qu\u00e9 se hace? Los cient\u00edficos buscan formas de bloquear la inflamaci\u00f3n sin perder la ventaja de la protecci\u00f3n bacteriana.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mientras tanto, la recomendaci\u00f3n es la de siempre: no se rasque. Claro, f\u00e1cil de decir, pero a ver qui\u00e9n resiste.<\/p>\n\n\n\n<div class=\"wp-block-uagb-container uagb-block-e31d8b4a alignwide uagb-is-root-container\">\n<div class=\"wp-block-uagb-advanced-heading uagb-block-55d4c858\"><h4 class=\"uagb-heading-text\">\u00daltimas noticias de la secci\u00f3n Salud:<\/h4><\/div>\n\n\n\n\t\t\t<div class=\"wp-block-uagb-post-carousel uagb-post-grid  uagb-post__image-position-top uagb-post__image-enabled uagb-block-24e22604     uagb-post__arrow-outside uagb-slick-carousel uagb-post__items uagb-post__columns-3 is-carousel uagb-post__columns-tablet-2 uagb-post__columns-mobile-1\" data-total=\"45\" style=\"\">\n\n\t\t\t\t\t\t\t\t\t\t\t\t<article class=\"uagb-post__inner-wrap\">\t\t\t\t\t\t\t\t<div class='uagb-post__image'>\n\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/agencia.unq.edu.ar\/?p=39774\" target=\"_self\" rel=\"bookmark noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"388\" src=\"https:\/\/agencia.unq.edu.ar\/wp-content\/uploads\/2026\/10\/depositphotos.jpg\" class=\"attachment-medium size-medium\" alt=\"La evaluaci\u00f3n del estado general del paciente es parte de la atenci\u00f3n oncol\u00f3gica.
