Adequate hydration is very important because all processes in the body take place in water. Did you know that water makes up <strong>approximately 60% of body weight<\/strong> in the average adult?  <\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Simply put, no one can do without water. Adequate intake has a positive effect not only on health, but also on sports performance. Calculate how many litres of fluid you should consume per day.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Use_the_Online_Hydration_Calculator\"><\/span>How to Use the Online Hydration Calculator? <span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Enter your gender and body weight in the form.*<\/li>\n\n\n\n<li>Click the \u201cCalculate\u201d button.<\/li>\n\n\n\n<li>The calculator will then calculate the interval of daily recommended fluid intake in litres.<\/li>\n<\/ol>\n\n\n\n<p>*If you are significantly overweight or obese, do not calculate with your current weight. The recommended fluid intake would then be too high. Calculate what your weight would be at a BMI of 24 and use this adjusted value. For example, our <a href=\"https:\/\/gymbeam.com\/blog\/bmi-calculator\/\">online BMI calculator<\/a> can help you with the calculation.    <\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div style=\"padding: 40px; background: linear-gradient(135deg, #ff4100 0%, #ff5500 100%); color: white; text-align: center; border-radius: 8px;\">\n                    <div style=\"font-size: 50px; margin-bottom: 20px;\">\ud83d\udca7<\/div>\n                    <h3 style=\"margin-bottom: 10px;\">Hydrata\u010dn\u00e1 kalkula\u010dka<\/h3>\n                    <p style=\"opacity: 0.9;\">Kalkula\u010dka sa zobraz\u00ed na front-ende<\/p>\n                <\/div>\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>During the day, a person loses an average of around <strong>1.5\u20133 l of fluids<\/strong>, if we take into account water losses through normal <strong>sweating, urine, stool, breathing<\/strong> and <strong>skin<\/strong>.

We ask it over and over again because it is known that <g id=\"gid_1\">caffeine has a diuretic effect<\/g> (promotes urine excretion). But fortunately, this is nothing you need to worry about if you don&#8217;t consume too much caffeine per day.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>A <strong>daily dose of caffeine up to 400 mg,<\/strong> which is also considered the upper safe limit for health according to EFSA (European Food Safety Authority) for an average 70 kg person, <strong>has no negative effect on hydration<\/strong>. In practice, this corresponds to approximately <strong>4\u20135 cups of coffee<\/strong> (espresso, cappuccino, etc.).
