One of the most dramatic options on the Lyme menu — the body is heated to a controlled fever hot enough to kill Borrelia. The science is real, the results can be real — and it’s also serious, expensive, not-for-young-kids medicine. Here’s the honest version: what it is, the research, the real risks, how to access it, and how to vet a clinic.
I walked this part of the labyrinth myself — knocked on the doors, read the research, and came back with the map. You don’t have to find the way out alone.
Whole-body hyperthermia raises your core temperature to about 107°F (41.6°C) and holds it for 2–3 hours, under medical supervision and sedation. Borrelia is heat-sensitive: as the temperature climbs it loses mobility, then sheds its outer membrane, and at roughly 107°F the bacteria die. It’s a blunt, powerful way to reach spirochetes that hide where antibiotics struggle.
Does it kill the co-infections too? You’ll hear clinics and families say it “clears them all” — that’s overstated. The honest answer is partly. The hard “100% kill” data is Borrelia-specific. Bartonella and Babesia are considered heat-sensitive and the clinics report a positive effect — but there’s no clean kill study for them. The bigger reason it helps the co-infections: hyperthermia is run alongside combination antibiotics, and the heat drives those drugs deep into the cells and biofilms where Bartonella hides. So it can help with Bartonella — but Bartonella still needs its own combination antibiotics (rifampin + azithromycin/doxycycline); don’t count on heat alone to clear it.
And the results can be dramatic. Some people have walked into these clinics in wheelchairs and walked out — for the right person it can feel like a miracle, and that hope is real. Hold it honestly, too: it doesn’t happen for everyone, it’s serious and expensive, and it works as part of a fuller plan, not a guarantee.
The honest framing — it is NOT a standalone cure. Even its proponents describe it as “a piece of the puzzle” — it’s done alongside antibiotics and detox/drainage, and it can be a helpful (expensive) step toward remission, not a one-and-done fix.

Hyperthermia isn’t for everyone — in fact, for most kids on this map, it isn’t an option at all. Start here. Tap to open.
Yes → this isn’t for you. The clinics doing whole-body hyperthermia do not treat children under 14 — the cardiovascular and sedation demands are too high for a young body. Stop here and work the rest of the menu (antibiotics, herbals, the other modalities).
If yes → likely contraindicated. Whole-body hyperthermia is not safe with kidney insufficiency, significant cardiac or pulmonary disease, a clotting/thrombosis history, or an acute active infection. This must be screened by the clinic’s physicians before anyone proceeds.
Then it’s a real option to explore — at a specialized clinic (see How to access it below), ideally coordinated through a concierge who knows them. Go in knowing it’s paired with antibiotics + detox, not a cure on its own, and that it is not cheap and not covered by insurance.
A powerful kill step, wrapped inside a fuller protocol. Expect to support drainage hard around it (a big die-off is the whole point), and to keep treating with antimicrobials after. It buys you a major reduction in spirochete load — not a finish line.

Heating a body to fever-range under sedation carries real, non-trivial risk. Reported and expected concerns:
It’s done at a handful of specialized international clinics. The realistic doors:
| Clinic | What to know |
|---|---|
| Lyme Mexico (Cancún — Dr. Omar Morales) | Aggressive IV + hyperthermia protocols; the most-traveled-to option for North American families. |
| Alpine Biomedical (Switzerland) | Whole-body hyperthermia within a broader biological-medicine program. |
| Klinik St. Georg (Bad Aibling, Germany) | One of the longest-running European hyperthermia centers for Lyme. |
The Lyme Specialist (thelymespecialist.com, Michelle McKeon, NY) coordinates these international clinics — she has relationships with them, helps families get in the door, and can steer you toward a more holistic approach first. Worth a call before you book anything. Plan B doesn’t vouch for outcomes — it’s an access starting point; vet it like anything else.
Cost reality: travel + a 1–3 week stay + the procedure runs into many thousands of dollars, out of pocket. Budget honestly before you commit.
Credentials, polish, and how conventional an approach sounds tell you little about whether a practitioner will help your child — or harm them. What does: their behavior and their incentives. Watch those.
Hyperthermia’s heat-kill biology is real and powerful, and for an eligible older child or teen with chronic, treatment-resistant Lyme it can be a meaningful step — but it is not a standalone cure, not for kids under 14, carries genuine medical risk, and costs real money out of pocket. If you pursue it, do it through a credible clinic with full screening, wrapped in a broader protocol, with drainage supported hard. This is parent education, not medical advice — bring it to a treating physician as questions, not instructions.
This is a lot — and you don’t have to hold it alone. Minta has all of this synthesized. She’ll look at your child, tell you whether hyperthermia even fits, recommend the right tests, and build you a plan. Let Minta do this for you →
Plan B does not partner with drug companies or doctors, and we never endorse anyone whose healing isn’t verified by families. We show you the options and how to vet them yourself — and we’re building parent verification: look up a clinic or practitioner and see real family reviews before you trust them. Universal bad reviews? Skip.
