What it is

The AFNOR standard defines thalassotherapy as "l'utilisation combinée des bienfaits du milieu marin" (translated: the combined use of the benefits of the marine environment). That covers sea climate, seawater, marine mud, seaweed (algae), sand and other substances taken from the sea. An older…

Format

• Thalassotherapy is a service format delivered in a centre, not a staged psychotherapy. The "framework" below describes how a stay is organised as sources describe it, followed by the psychotherapist's parallel arc.
• Programme of care. Clients receive individual treatments: marine wraps or applications, programmable tubs with jets, jet showers. They also take part in group sessions in a seawater pool (pool exercise or specific rehabilitation), and receive massage. Packages are themed: well-being, "anti-stress",…

Who practises it, and how they are trained or regulated

• Who delivers it. The AFNOR standard sets minimum staff competencies. It names the roles of hydrotherapist, beautician, hydro-beautician and masseur-physiotherapist (masseur-kinésithérapeute, a regulated health profession in France). The cited press release does not mention a requirement for medical staff. A consumer guide states that each centre has a doctor who checks fitness and contraindications, but Que Choisir…
• Admission and medical screening. A medical certificate is commonly required on arrival. An on-site medical consultation is described as strongly recommended rather than mandatory, and is not reimbursed. Treatments are then chosen or excluded according to the client's health. Goal: exclude contraindications. Criterion for moving on: medical clearance.

Evidence status, as the guide reports it

• René Quinton and "marine plasma" (contested). The biologist René Quinton (1866–1925) argued that seawater is the body's original internal milieu. He set this out in L'eau de mer, milieu organique (1904). He patented a sterilised, diluted seawater "sérum de Quinton" in 1907 and made broad…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• 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?
• 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

• confidentiality breaches; the client feeling labelled.
• turning the note into self-monitoring of weight or appearance.
• delayed infection symptoms; under-reporting of misconduct out of shame.
• minimising symptoms to get a booking; alcohol use during stays; pregnancy that has not been disclosed to the centre.
• panic, hyperventilation or dissociation in water. A client who "goes blank" in water should leave and be supervised.

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.
