What it is

WBH is a medical procedure in which a person lies in a heating device while research or clinical staff raise and then let down core body temperature under monitoring. The devices described differ: an enclosure heating the trunk with infrared light and the legs with heating coils (Arizona trial, as…

Format

• Treatment sessions. Arizona: one active session versus a sham that matched it in length and in everything except intense heat. Essen: two WBH sessions within two weeks versus a waiting control. HeatBed: planned eight weekly WBH sessions, reduced partway through (with IRB approval) to four sessions…
• After the course. No source here sets out maintenance sessions or a relapse-prevention protocol after WBH.

Who practises it, and how they are trained or regulated

• Preparation. HeatBed asked participants to abstain from nicotine, cannabis and alcohol around sessions and to avoid heavy exercise on session days; medicines affecting heat regulation were exclusions.
• HeatBed (single arm, 16 adults): 13 of 16 completed at least four WBH sessions. Among the 12 at the final visit, BDI-II fell by a mean of 15.8 points and 11 of 12 no longer met criteria for major depressive disorder. Negative automatic thinking improved; cognitive flexibility did not. Mood improvement after the first WBH session predicted BDI-II change; mood change after the first CBT session did not. The authors…

Evidence status, as the guide reports it

• Janssen et al. 2016 (randomised, double-blind, sham-controlled; 34 randomised, 29 in the efficacy analysis): the WBH group had lower HAM-D scores than sham at every follow-up: about 6.5 points lower at week 1, 6.4 at week 2, 4.5 at week 4 and 4.3 at week 6. Adverse events were generally mild in…

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 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

• the client planning home heat as a backup; avoidance of ending. Working if the plan is concrete and the client can say who they will contact.
• belief that only the heat helps (dependence on access to it); shame if it did not help. Working if the client names their own actions as part of the change.
• high anticipatory anxiety, dissociation when imagining the enclosure, reluctance to speak up to staff. Working if the client can say what they will do if they want to stop.
• stopping medicines without telling anyone; withdrawal or relapse symptoms; prescriber not informed. Working if the client and prescriber have discussed it before any decision.
• services that skip medical screening or promise cures; the client using the trial in place of all other support. Working if there is a clear shared plan and a named medical lead.

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.
