"In our fingers we have small capillaries that are responsible for taking nutrients to the tissues and collecting waste. Nutrients arrive through arterioles and waste leaves through venules", explains Carolina.</p> <span class="dynamic-ad-module "/><span class="content-ad-module "> <span class="content-ad visible-xs roba-container hidden-ad"><span class="ad-unit roba"> </span></span></span><p data-gtm-element-container="modulo-texto-link" class="paragraph">“When your hands or feet get cold, the following happens: the arterioles <strong>They close so that warm blood does not reach the surface </strong>and we lose heat, and the venules also close and the capillaries become empty. <strong>Your skin turns white and cold</strong>”, he adds.</p> <span class="content-free-html "/><p data-gtm-element-container="modulo-texto-link" class="paragraph">But that’s not what causes chilblains to appear: “<strong>The real problem is not the cold itself, but how you keep warm</strong>. If you do this quickly and abruptly, the arterioles open quickly and blood quickly enters the fingers, but the venules remain dormant and take longer to open, so the blood has nowhere to go. <strong>This causes some of the blood fluid to start leaking into the tissue because the capillaries are overflowing.</strong>. “This is what causes swelling, pain and itching.”</p> <span class="dynamic-ad-module "/><span class="content-ad-module "> <span class="content-ad visible-xs roba-container hidden-ad"><span class="ad-unit roba"> </span></span></span> <figure class="composite-image image-container " data-gtm-element-container="button-gallery"> <div class="picture-wrapper"> <picture> <source media="(min-width: 638px)" data-srcset="https://www.mundodeportivo.com/files/content_image_desktop_filter/uploads/2026/02/03/6981fe5e4dd99.jpeg" width="544" height="363"> <source media="(min-width: 480px)" data-srcset="https://www.mundodeportivo.com/files/content_image_intermediate_filter/uploads/2026/02/03/6981fe5e4dd99.jpeg" width="607" height="405"> <img data-full-src="https://www.mundodeportivo.com/uploads/2026/02/03/6981fe5e4dd99.jpeg" alt="A person applying moisturizer to their hands." width="449" height="300" src="https://www.mundodeportivo.com/files/content_image_mobile_filter/uploads/2026/02/03/6981fe5e4dd99.jpeg" class="lazy"/> </source></source></picture><span class="visible-md inimage-container "><span class="ad-unit inimage"> </span></span><span class="visible-xs inimage-container "><span class="ad-unit inimage"> </span></span> </div> <figcaption class="figure-caption"> <p class="caption-title ">A person applying moisturizer to their hands.</p> <span class="caption-author ">Free</span> </figcaption> </figure> <span class="content-related content-border related-double " data-gtm-element-container="modulo-noticias-relacionadas"> <span class="module-supra-title"> <span>Also read</span></span> <span class="related-double-module-container "> </span><span class="related-double-module-container "> </span></span><span class="content-subtitle-simple "> <h2 class="subtitle">How to avoid chilblains and how to treat them?<br/></h2></span><p data-gtm-element-container="modulo-texto-link" class="paragraph">Taking this explanation into account, the biologist is clear: to prevent the appearance of chilblains<strong> Sudden changes in temperature must be avoided and, if we have to heat up, this must be done progressively, little by little.</strong>.
