When harmful microorganisms such as viruses or bacteria enter the body, immune cells release\u00a0certain\u00a0chemical messengers. These substances act on the region of the brain responsible for regulating body temperature, causing it to raise the temperature.\u00a0<\/p>\n\n\n\n<p>The body\u00a0then\u00a0tries to\u00a0reach and\u00a0maintain\u00a0this\u00a0new, higher\u00a0temperature\u00a0point\u00a0by conserving\u00a0heat through mechanisms such as shivering, narrowing of blood vessels in the skin, and increased metabolic activity. The elevated temperature creates an environment that may slow the growth and reproduction of certain pathogens while enhancing the activity of immune cells involved in fighting infection.\u00a0Once the\u00a0underlying cause of\u00a0the fever\u00a0begins to\u00a0resolve,\u00a0sweating occurs,\u00a0the\u00a0temperature\u00a0falls, and the fever subsides<sup><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21843857\/\" target=\"_blank\" rel=\"noreferrer noopener\">3<\/a>,<a href=\"http:\/\/www.ncbi.nlm.nih.gov\/books\/NBK562334\/\" target=\"_blank\" rel=\"noreferrer noopener\">4<\/a><\/sup>.<\/p>\n\n\n\n<p>Therefore, fever should be viewed as an important warning sign and a protective physiological response rather than a\u00a0disease in itself.\u00a0\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Is_It_Normal_for_Fever_to_Go_Away_in_1%E2%80%932_Days\"><\/span><strong>Is It Normal for Fever to Go Away in 1\u20132 Days?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>It\u00a0may be\u00a0normal for\u00a0the\u00a0fever to go away within a couple of days, especially when it is caused by a mild viral infection.\u00a0As discussed above, fever is part of the body\u2019s natural immune response, and as the immune system begins to control the infection, body temperature may return to normal\u00a0relatively quickly<sup><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC7812885\/\" target=\"_blank\" rel=\"noreferrer noopener\">5<\/a><\/sup>.<\/p><div id=\"sfa_container_281093\" class=\"sfa_container\" style=\"display:none\"><div class=\"sfa_overlay\"><\/div><button id=\"sfa_btn_281093\" class=\"sfa_btn\">Show Full Article<\/button><\/div>\n\n\n\n<p>However,\u00a0if the\u00a0fever goes away and comes back days\u00a0later<strong>,\u00a0<\/strong>it may mean that\u00a0the underlying illness\u00a0hasn\u2019t\u00a0fully resolved\u00a0or has recurred.
