Can Tea Replace Water? How Much Tea to Drink a Day

Tea can’t replace water. Even though tea is mostly water and contains amino acids and other natural compounds, plain water is still the best everyday drink for staying hydrated. Enjoy tea in moderation, keep it light, and drink water alongside it.

Many people don’t like plain water because it tastes like nothing, so they drink tea all day instead. Here is why tea and water should work together, and how much tea makes sense in a day.

Why can’t tea replace water?

  • Your body still needs plain water. Nutrients in tea need water to be absorbed and used, and plain water does that job best.
  • Strong tea brings a lot of caffeine. Drinking cup after cup of strong tea in place of water means a large daily dose of caffeine, which can leave you jittery or keep you awake. See caffeine in different types of tea.
  • Traditional Chinese advice favors balance. A Chinese saying goes “清茶淡饭” (qīng chá dàn fàn), “light tea and plain rice,” meaning a simple, moderate life is the healthy one.

These are traditional views, not medical claims. Tea is not intended to diagnose, treat or prevent any disease.

How many cups of tea should you drink a day?

There is no single right number, and it depends on how strong you brew and how sensitive you are to caffeine. Here is a sensible approach we use ourselves:

  • Use a moderate amount of leaf, for example 3–5 g in a gaiwan or a teaspoon or two for a large pot, and re-steep the same leaves rather than starting over with fresh leaf.
  • Drink a glass of water between pots.
  • Choose fresh green or white tea in the morning and mellow black tea or ripe pu-erh in the afternoon.
  • Stop several hours before bed if caffeine keeps you awake.

What is the best way to enjoy tea every day?

Think of tea as something to savor, not just something to drink when you are thirsty. Brew a small pot, smell the aroma and taste each infusion. You’ll drink less, notice more and still keep your water bottle nearby. For ideas, read tea at different times of day and four times not to drink tea.
