You’ve booked your spa day. Good. Now the real question: how do you make the most of it?
Because a day at a thermal spa is a different experience from a gym visit or an afternoon at a café. There’s a logic, a rhythm, a way of doing things that transforms a great experience into something exceptional. Here’s your guide to not missing a thing — and most importantly, not leaving thinking I should have tried that.
Before you arrive: a few small details
- Eat light before your visit. A full stomach and intense heat is an uncomfortable combination.
- Stay well hydrated in the hours leading up. You’ll be sweating (that’s the point), so arrive with good reserves.
- Bring a swimsuit, sandals, and that’s about it. Kōena provides towels and robes, for $9.
The thermal circuit: understanding the hot-cold logic
The principle behind nordic baths is thermal contrast. It’s not just for the atmosphere — there’s real physiology behind it.
The basic sequence is simple: heat → cold → rest. Then repeat.
Here’s how to approach each step:
1. Start by warming up gradually
Don’t dive straight into the hottest sauna or the 40°C whirlpool the moment you arrive. Let your body adapt. The temperate pool is a good starting point. Take 10 to 15 minutes to feel the warmth work its way into your muscles, your neck, your shoulders.
2. The sauna: dry heat
Once you’re well warmed up, head to the sauna. The dry heat in one of our saunas reaches up to 80–90°C. Stay between 8 and 15 minutes, depending on your comfort level. The golden rule: listen to your body. If you feel dizzy or uncomfortable, step out. There’s no virtue in pushing through.
3. The cold plunge
This is often the part people dread. It’s also the one they talk about most afterward.
Right after the sauna, head to the cold bath or cold shower. The water is around 10–15°C. Stay for 30 seconds to 2 minutes. Your body responds immediately: blood vessels contract, your heart races for a moment, then a rush of euphoria sets in. It’s real — that’s your endorphins doing their work.
At Kōena, the cold bath is an option for the more daring. A few seconds is all it takes.
4. Rest — the most underrated part
Between each hot-cold cycle, rest. Really rest. Not on your phone. Not mentally planning dinner. Kōena’s relaxation areas are designed exactly for this: hammocks, lounge chairs, covered or sunny spaces depending on your preference.
This rest time is essential — it’s where the magic happens, where the nervous system resets, where stress dissolves.
5. How many cycles should you do?
Generally, 3 to 4 cycles is ideal for a 3 to 4 hour visit. You can vary your heat sources: Finnish sauna, hammam, hot pool, whirlpool. Each has its own character, and alternating between them enriches the experie
Adding a treatment: timing it right
If you’ve booked a massage or a treatment, schedule it after your first thermal cycles, not before. Muscles that are already warmed up and loosened are far more receptive to bodywork. The effect of the massage will be multiplied.
Dining: taking a real break
At midday (or whenever hunger strikes), take a meal break. The ONŌ and KaTO restaurants offer cuisine in the spirit of the place: fresh, flavourful, nourishing without weighing you down. It’s an integral part of the experience — not just an intermission.
Finishing gently
For the last hour, slow down. Less sauna, more rest. A final warm bath, a herbal tea, a quiet moment in the indoor relaxation areas. The idea is to ease your body back into the outside world gradually — and carry that state of calm with you for as long as possible.
What to expect afterward
That same evening, you’ll likely sleep better than usual. The next day, your muscles may feel slightly sore — that’s normal and passes within 24 hours. What stays is a clarity, a lightness, and the desire to come back.
