Sauna Hydration and Safety

How long, how often, how much water — and when not to

By Navitas Spa & SportsPublished: 25 August 20261 min read

At a glance

Use the sauna in rounds of 8–15 minutes with a cool shower and rest between, two or three rounds at most; drink a large glass of water before and after each round; avoid alcohol and heavy meals beforehand; and skip the sauna in pregnancy, with a fever, after excessive alcohol, when dehydrated after a long flight, or with uncontrolled heart or blood-pressure conditions.

The safe pattern

  1. 01Drink water; shower.
  2. 028–15 minutes on the lower bench first, then higher if comfortable.
  3. 03Cool shower — the bucket shower beside our sauna is made for this.
  4. 04Rest 5–10 minutes with water.
  5. 05Repeat once or twice; stop when you feel done, not when the timer says so.

Water

You lose roughly half a litre of sweat in a normal round. Drink a large glass before, after each round and again afterwards; add electrolytes after a long flight, when you are already behind.

Skip it when

  • Pregnant
  • Feverish or unwell
  • After alcohol
  • Straight off a long-haul flight without rehydrating
  • With uncontrolled heart, blood-pressure or circulation conditions
  • On medications that affect heat tolerance — ask your doctor

If you feel dizzy, nauseous or your heart races, leave, sit low, drink water and tell our team.

Frequently asked questions

Sauna before a massage?

Yes — one round, then a cool shower. Warm muscles accept pressure more easily.

How hot is the sauna at the spa?

A classic Finnish range; ask the team for the current setting.
