What it is

An infrared sauna heats the body mainly by infrared radiation from heater panels rather than by first heating the air, so users sweat and their heart rate rises at a lower air temperature than in a traditional Finnish-style sauna; Mayo Clinic describes the effect as similar to moderate exercise and…

Format

• Format: a supervised in-hospital course of sessions, each a dry-sauna phase followed by warm rest under covers and fluid replacement, with patients weighed before and after each session. Settings and timings are deliberately not given here.
• Target group: chronic heart failure with an established underlying diagnosis, NYHA II–IV (class IV only if able to move by wheelchair); aortic stenosis and obstructive hypertrophic cardiomyopathy excluded.

Who practises it, and how they are trained or regulated

• Who delivers: a hospital cardiology department. The 2010 application required a responsible physician who is a certified cardiologist with years of departmental experience and prior cases of the technique, in a department with several physicians. It uses a dedicated far-infrared dry "uniform" sauna treatment device (遠赤外線乾式均等サウナ治療装置), not an ordinary sauna.
• Masuda et al. (2005) randomised 28 mildly depressed inpatients with fatigue and appetite loss to repeated far-infrared sauna (Waon-type) sessions or no thermal therapy over several weeks; somatic complaints, hunger and relaxation scores improved, mental complaints improved only non-significantly (p = .054), and plasma ghrelin and caloric intake rose. This is a single small pilot, not established treatment.
• No licensing of operators or users exists in the sources found; in the US, infrared saunas do not need pre-market approval, but the FDA can act when sellers make specific medical claims. The therapist meets this setting when a client already uses, or wants to use, an infrared sauna.

Evidence status, as the guide reports it

• Evidence: in WAON-CHF, 149 hospitalised patients with advanced heart failure at 19 Japanese institutions were randomised to Waon therapy or control. The primary endpoint (change in BNP) did not differ significantly between groups; NYHA class, 6-minute walk distance and cardiothoracic ratio improved…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• clients who hide symptoms to keep using; repeated near-fainting. Working: symptoms are reported promptly and medical advice is followed.
• dissociation or feeling cut off in heat; distress in enclosed devices; the sauna becoming the only regulation strategy. Working: the client can name and reach calm states by several routes.
• rising frequency, secrecy, weighing before and after, spending beyond means, stopping medical care. Working: the behaviour is understood within the formulation and medical treatment continues.
• reluctance to involve the doctor (explore why, see 5.4); a client minimising cardiac symptoms; recent changes in psychiatric medicines. Working: the client has a clear answer from a physician or…
• hope that Waon will replace medicines or cure the illness (correct gently; it is an add-on with unproven hard outcomes); mood dips after admission or discharge. Working: the client's questions are…

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
