About ActiveHydration

Who is behind the site

Health content on ActiveHydration is fact-checked by Nico, a certified personal trainer & health coach. Nico checks every health page against the sources listed at the bottom of that page before it is published.

How we make our calculators

Every calculator shows the formula or guideline it uses, such as National Academies intake references, ACSM position stands, NOAA heat index or CDC/NIOSH heat guidance. When something is a rule of thumb rather than a study result, we say so.

Editorial standards

We only publish a page when it answers a real question with something useful: a calculator, a worked example or a table.

We cite sources and never make up statistics.

We are not doctors and we do not diagnose or treat. See our health disclaimer.

How we make money

The site is free. It may show ads and may earn a commission on some product links. That never changes the numbers our calculators give you. See the affiliate disclosure.
