Tutto quello che devi sapere sull'idratazione giornaliera
Quanta acqua devo bere al giorno?
La regola comune è 8 bicchieri (2 litri) al giorno, ma il fabbisogno varia molto in base al peso corporeo, livello di attività, clima e dieta. Una stima più precisa è 30-40 ml per kg di peso corporeo al giorno. Il tool calcola un valore personalizzato.
Come capire se bevo abbastanza?
Il colore delle urine è il miglior indicatore: giallo pallido = ben idratato, giallo scuro = bevi di più, trasparente = potresti bere troppo. La sete è già un segnale di lieve disidratazione. Frutta e verdura contribuiscono al fabbisogno idrico (fino al 20%).
L'attività fisica aumenta il fabbisogno?
Sì, durante l'esercizio fisico si perde acqua attraverso il sudore e la respirazione. La regola è bere 500ml extra per ogni ora di attività moderata e fino a 1 litro per attività intense. In climi caldi il fabbisogno aumenta ulteriormente.
How much water should I drink a day?
The usual rule is eight glasses, about two litres, but the need shifts with body weight, movement, climate and diet. A closer estimate is 30 to 40 ml per kilo of body weight a day, which is what this calculator uses.
How do I tell whether I am drinking enough?
The colour of your urine is the best sign: pale yellow means well hydrated, dark yellow means drink more. Thirst is already mild dehydration, and fruit and vegetables cover up to a fifth of what you need.
Does exercise raise how much I need?
Yes, because training loses water through sweat and breathing. The practical rule is half a litre more per hour of moderate activity, up to a litre for hard effort, and heat raises it further still.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
