A website that allows you to easily and accurately calculate the amount of water lost from the human body in a day has appeared



Yosuke Yamada, Director of

the Exercise Guidelines Laboratory, Physical Activity Research Department, National Institute of Biomedical Innovation, Health and Nutrition (NIBIOHN), as well as researchers from Waseda University, Kyoto University of Advanced Science, the University of Tsukuba, as well as from China, the United Kingdom, the United States, Canada, etc. Researchers from research institutions have jointly published a calculation formula that accurately predicts the amount of water lost from the body in a day. Based on this calculation formula, a site called ` `Water Loss Calculator'' has appeared that allows you to easily calculate the amount of water lost in a day on your browser, so I actually entered it and measured it.

The details of the research and calculation formula are explained in the article below.

A calculation formula that can accurately predict the amount of water lost from the human body in a day has been found - GIGAZINE



The daily water loss calculator is based on published formulas, and includes factors such as ``physical activity level'', ``weight (kg)'', ``gender'', ``daily average humidity (%)'', ``whether you are an athlete or not'', and ``human development''. You must enter the following information: index, altitude (m), age (years), and average temperature (℃).



This time, the physical activity level is 'mainly sedentary (1.5)', the weight (kg) is '72', the gender is 'male (1)', and the average daily humidity (%) is

as of October 2022 according to the Japan Meteorological Agency. '75' based on Tokyo data , 'Not an athlete (0)' for athlete or not, 'Developed country (0)' for human development index, Altitude (m) is a site that summarizes altitude data from various parts of Japan・I entered '5' for the elevation based on the sea level navigation , '30' for the age (years), and '17.2' for the average temperature based on data from the Japan Meteorological Agency for Tokyo in October 2022 . After entering all items, click 'Calculate'.



Then, the amount of water lost from the body per day (ml/day) was calculated to be '3386.7476'.



However, the research team stated in a press release :

One thing to keep in mind here is that even if a man in his 20s loses an average of 4.2 liters of water a day, he doesn't need to drink 4.2 liters of water a day. Approximately 10% (approximately 0.4 liters) of water is produced in the body during the energy metabolism process, and some water also enters the body through exhalation. Therefore, approximately 85% (approximately 3.6 liters) of this amount should be used as a guideline for water intake. Additionally, many foods contain water, so just eating a solid meal means you'll be drinking a lot of water. For Japanese people, if they eat three typical meals, they will ingest about half of their 3.6 liters of water from their meals, and the amount of fluid they need for hydration is about 1.8 liters per day. It will be ℓ. For women in their 20s, this is about 1.4 liters a day.


Even if the calculation result shows that approximately 3.4 liters of water is lost per day, it does not necessarily mean that you need to drink approximately 3.4 liters of water every day. Half, or about 1.7 liters, seems to be enough.
