Hydration Guide: Why Water Matters for Performance
Water makes up about 60-70% of your body weight and is vital for every physiological system. Proper hydration not only regulates body temperature but also maintains cognitive function and physical performance. Calculating your water needs based on body weight is a simple yet powerful way to support your daily well-being.
Signs of Dehydration You Should Recognize
Dehydration isn't just about feeling thirsty; it also includes symptoms like headaches, fatigue, and dark-colored urine. Drinking enough water helps keep your skin hydrated, improves digestion, and ensures efficient fat metabolism.
Weight-Based Calculation Standards
The baseline recommendation is approximately 33-35 ml of water per 1 kg of body weight. For example, if you weigh 60 kg, you should drink about 2,100 ml per day. However, this amount should be adjusted based on activity levels and environmental temperature.
Exceptions for Medical Conditions and Weather
Individuals with certain medical conditions, such as kidney or heart disease, may need to limit fluid intake as advised by their doctor. Conversely, if you exercise intensely or are in a very hot climate, you should increase intake by 500-1,000 ml over the calculated value.
How is it calculated?
Global standard: [Weight (kg) x 2.2 x 30 / 2] in milliliters.
Why should you know this?
Even mild dehydration can impair cognitive function and physical performance.
