Nearly everyone who tries the sauna and likes it asks the same question on the way out: how often should I be doing this?

The honest answer is that it depends on why you are here — but there is a defensible default, and it is lower than most enthusiasts will tell you.

The default: two to three times a week

For most people, most of the time, two to three sessions a week is where the benefit shows up and the cost — in time, in money, in effort — stays reasonable.

At that frequency people most commonly report better sleep, less general stiffness, and a mood benefit that becomes noticeable in the depths of winter. Below that, sauna tends to be pleasant but forgettable. Above it, returns diminish for most people who are not training hard.

The reason has less to do with physiology than with life. A twice-weekly habit survives a busy month. A five-times-weekly habit collapses the first week something goes wrong, and then does not restart.

Adjusting for what you are actually after

General wellbeing and stress. Two a week. Consistency matters far more than length; two 30-minute sessions beat one 60-minute session comfortably.

Recovery from training or heavy physical work. Three to four a week, ideally within a few hours of the work. Shorter sessions are fine here — 15 to 30 minutes post-effort is plenty.

Winter mood. Two to three a week, and try to make one of them a daylight-hours session if your schedule allows. Adding chromotherapy is worth doing deliberately rather than at random.

Sleep. Two to three a week, in the evening — a couple of hours before bed rather than immediately before. The cooling-down phase afterwards is part of the effect.

Sore muscles and stiffness. Three a week during a hard stretch, dropping to two when things settle.

Building up sensibly

If you have never used an infrared sauna, do not start at 60 minutes.

  1. Weeks 1–2: 15 minutes, once or twice a week. Learn how your body responds.
  2. Weeks 3–4: 30 minutes, twice a week. This is where most people settle permanently.
  3. Month 2 onward: add a third session, or extend one to 60 minutes — one change at a time, not both.

Session lengths and packages are on the sauna page, including monthly packages structured around weekly booking, which exist precisely because weekly rhythm is what makes this work.

Hydration, properly

This becomes the limiting factor as frequency rises, and most people do it badly.

  • Start hours before, not on the way in. Arriving already dehydrated is the most common reason people feel wrung out afterwards.
  • Drink during, not just after. Bring water in with you.
  • Replace electrolytes if you are going three or more times a week, or sweating heavily. Water alone at high sweat volumes is not sufficient.
  • Watch the obvious signals: urine colour, headache, that flat feeling the next morning.

Signs you are doing too much

Sauna is a stressor. A useful one, applied well — but a stressor, and stress needs recovery.

  • Sleeping worse, not better. The clearest early signal.
  • Headaches after sessions, especially the next morning.
  • Lingering fatigue rather than the pleasant tiredness of a good session.
  • Dizziness on standing. Stop, hydrate, and cut back.
  • Dreading it. Under-rated as a signal. If a thing you chose to do feels like a chore, do it less.

The correct response to any of these is to reduce frequency or length for a couple of weeks, not to push through.

Who should check with a doctor first

Talk to your physician before starting a sauna routine if you are pregnant, have a heart condition, have low or unstable blood pressure, are on medication affecting heat tolerance or fluid balance, or have a condition that impairs sweating or heat regulation. Sauna is a wellness practice, not a treatment.

Making it stick

  • Same days every week. Tuesday and Friday beats "twice a week, whenever".
  • Attach it to something. After the gym. Before a Friday night. On the way home.
  • Book ahead. A booked appointment is kept; an intention is not. Monthly packages help precisely because they are structured around weekly booking.
  • Use the shower. Every session includes a private spa shower with AVEDA products. It turns a sweat into an actual break.
  • Bring someone. A second participant can be added to 30 or 60 minute sessions, and a habit with a friend attached survives January.
