Ten minutes, a scent you choose and the rhythm of warm then cold: many people use the ritual as a pause to slow down, morning or evening.
02
A slower rhythm.
When your face meets cold water, your body triggers the mammalian dive reflex: the heart rate slows and the vagus nerve, part of the parasympathetic ("rest and digest") nervous system, is engaged. It is a reflex your body already has.
The built-in aromatherapy diffuser adds a sensory cue that helps turn the routine into a calming habit. Guided breathing during facial immersion using the Frosteam Dive Breather helps you stay calm and steady through the cold.

A mental reset.
Many people describe feeling more awake and focused after the cold plunge. A ritual that asks you to slow down for ten minutes also helps you refocus.
The dive reflex, up close
Your face meets the cold. Your body answers.

A slower rhythm
Before
During the dip
The heart briefly slows when your face meets cold water. Doctors call it bradycardia; in the dive reflex it is short and natural.
Rest and digest

Fight or flight · sympathetic
Rest and digest · parasympathetic
The reflex engages the vagus nerve, part of the parasympathetic nervous system.
Slower, deeper breaths
Steady breathing helps you settle into the cold. The Dive Breather guides each breath.
Cold, held steady
Harmony spec
1–4°C
The basin stays between 1 and 4 °C for the whole session, so every dip starts as cold as the first.

Less puffiness.
Cold water narrows the small blood vessels of the skin and helps reduce the look of temporary puffiness, especially in the morning. Harmony's basin is held at 1–4 °C, so every dip delivers the same cold.

A healthy-looking glow.
Warm steam first, then the cold: after the ritual, skin looks fresher and more awake, with a firmer-looking finish.

Prepared for your skincare.
Nano-ionic steam at about 70 °C softens the outer layer of the skin, helps loosen surface build-up before cleansing and prepares the skin for the serums and creams you apply next.

A refreshed appearance.
A fresh, awake look right after the session. The effect is immediate and temporary: a visual refresh, not a permanent change.
Immediate
Results are cosmetic and temporary, and vary from person to person.
The science
Steam, cold, scent. Explained.
General physiology described in research, not clinical results measured for Harmony.
01
≈ 70 °C
Nano-ionic steam
A fine steam at about 70 °C warms and softens the outer layer of the skin. It does not literally open pores: it helps loosen surface build-up so cleansing is easier and your skincare goes on comfortably.
What's documented
Pores have no muscles to open or close. Warmth and moisture soften the skin's surface, which is why steam is used before cleansing and treatments.
Cold narrows the small blood vessels of the skin, which helps reduce the look of temporary puffiness. Cold water on the face also triggers the mammalian dive reflex, which slows the heart rate.
What's documented
The narrowing of small blood vessels in response to cold, and the dive reflex triggered by facial cold-water immersion. Specific to Harmony: the basin is held at 1–4 °C, so the cold stays consistent from the first dip to the last.
The cold, a slower and calmer rhythm, the scent, a more awake feeling after the plunge.
Visible, immediately
A less puffy, fresher and more awake look. Cosmetic, temporary, and different for everyone.
With regular use
A consistent ritual: skin prepared before your skincare every time, and ten minutes that become a habit.
Documented in research
The mammalian dive reflex, and the narrowing of small blood vessels in response to cold.

Questions.
Are the effects permanent?+
No. The visible effects, a less puffy and fresher look, are temporary. The ritual is designed to be repeated, every day or 3 to 4 times a week.
Is Frosteam suitable for sensitive skin?+
Stop the session if your skin becomes painful, unusually red or irritated. If you have a skin condition or have had a recent facial procedure, talk to a healthcare professional before use.
What does the dive reflex feel like?+
An intense cold for a few seconds, then a slower, steadier rhythm as you breathe out. Keep each dip short, and use the Dive Breather to stay calm through the cold.
Can I use Frosteam every day?+
Yes. Use it every day, or 3 to 4 times a week depending on the results you want.
How does it fit into my skincare routine?+
Steam first, then the cold plunge. Then apply your serum and your moisturizer: the steam helps them go on more easily.
