Three or one liter a day?
As for daily hydration, opinions are drifting apart.
With a simple calculation you can find your optimal drinking amount.
Those who drink enough fill up the water deposits in the body, which is definitely healthy.
However, you can also drink too much or too little.
How much fluid we need every day depends on various factors, such as age, weight or the outside temperature and the associated sweating.
But there is a formula that can be used to calculate the personal perfect amount to drink.
Do you always drink when you are thirsty?
This can be the right decision in many cases, but the feeling of thirst disappears, especially with age - with sometimes fatal consequences such as dehydration *.
The other extreme is also possible: During marathon runs, for example, the runners repeatedly ingest too much fluid.
As a result, the blood thins and the sodium level can become extremely low, which can even be life-threatening.
There is no single rule for the optimal fluid intake:
But a simple formula helps to calculate the amount of
fluids you
drink each day

Stylish and sustainable: the drinking bottle for office, sport and school
The double-walled thermo stainless steel drinking bottle with a bamboo lid by PURWLD (promotional link) holds 750 milliliters and combines style and sustainability.
The bottle made in Germany is not only leak-proof and dishwasher-safe: BPA and other plasticizers were not used in its manufacture.
This is how much you should drink a day - calculate perfect hydration
If you calculate your personal fluid requirement, you can only determine the average value - factors such as physical exertion, pregnancy or obesity are not taken into account.
In these cases, the fluid requirement increases.
How much a healthy adult should drink per day without great physical exertion can be calculated using the following formula:
Kilograms of body weight x 35 milliliters of liquid
In the case of a person weighing 60 kilograms that would be 2,100 milliliters, a little more than two liters that they should drink per day.
The formula is adjusted for seniors aged 65 and over: Here, the body weight is only multiplied by 30 milliliters.
Tap water, mineral water, fruit and herbal teas and juice spritzers are best suited to meet daily needs.
Sugary drinks such as lemonade should be avoided as far as possible, as they promote obesity.
Contrary to many myths, coffee is one of the drinks that also cover the daily fluid requirement
