This <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC5957508\/\">basic physiological mechanism<\/a> is controlled mainly by part of the brain&#8217;s &#8220;control center,&#8221; called the hypothalamus.

Participants attended a lab in the morning and then later in the afternoon to provide markers of hydration status (such as urine, blood samples and body weight). The relationship between levels of thirst in the morning and afternoon hydration status was negligible.<\/p>\n<p>Further, thirst may be driven by environmental factors, such as access to water. For example, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/0031938484901549\">one study<\/a> looked at whether ample access to water in a lab influenced how much people drank and how hydrated they were. The link between how thirsty they felt and how hydrated they were was weak, suggesting the availability of water influenced their fluid intake more than thirst.<\/p>\n<p>Exercise can also <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6893511\/\">change our thirst mechanism<\/a>, though studies are limited at this stage.<\/p>\n<p>Interestingly, research shows women experience thirst more strongly than men, regardless of hydration status. To understand <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2475299123148852\">gender differences in thirst<\/a>, researchers infused men and women with fluids and then measured their thirst and how hydrated they were. They found women <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a>ly reported thirst at a lower level of fluid loss. Women have also been found to respond more <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.mdpi.com\/2072-6643\/16\/18\/3212\">to feeling thirsty<\/a> by drinking more water.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Other_ways_to_tell_if_you_need_to_drink_some_water\"><\/span>Other ways to tell if you need to drink some water<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While acknowledging some people will need to drink more or less, for many people, eight cups (or two liters) a day is a good amount of water to aim for.<\/p>\n<p>But beyond thirst, there are many other ways to tell whether you might need to drink more water.<\/p>\n<p><b>1. urine color:<\/b> pale yellow urine typically indicates good hydration, while darker, concentrated urine suggests dehydration<\/p>\n<p><b>2. frequency of going to the toilet:<\/b> <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK291\/\">urinating regularly<\/a> (around four to six times a day) indicates good hydration.

Higher levels of sweat may predispose a person to dehydration if they are unable to replace the fluid lost through water intake<\/p>\n<p>These indicators, used together, provide a more comprehensive picture of hydration without solely depending on the sensation of thirst.<\/p>\n<p>Of course, if you do feel thirsty, it&#8217;s still a good idea to drink some water.<\/p>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    The Conversation<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"https:\/\/theconversation.com\"><br \/>\n                                                        <svg><use href=\"https:\/\/medx.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/><\/svg><\/a><\/p><\/div>\n<p class=\"article-main__note mt-4\">\n                                                This article is republished from <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/theconversation.com\">The Conversation<\/a> under a Creative Commons license.
