Longevity screening, HBOT & acupuncture: what each can—and cannot—do

Broad biomarker panels can reveal diabetes risk, dyslipidaemia, kidney or liver abnormalities, nutritional deficits and other issues with established clinical consequences. Biological-age algorithms can summarise some of these patterns, but they should not replace the individual results.

That last point deserves more weight than it usually gets. Every test has a false-positive rate, and a panel of a hundred markers will produce some out-of-range values in a healthy person by chance alone. The question to ask before ordering is not only what an abnormal result would mean, but what would be done about a borderline one.

Almost every disagreement about longevity treatments comes down to one distinction: whether a study measured an outcome people care about, or a marker that stands in for one.

Most anti-ageing marketing draws on the bottom two rows while implying the top one. That is the single most useful pattern to recognise, because it applies equally to supplements, devices, infusions and clinic programmes.

Hyperbaric oxygen therapy increases the amount of dissolved oxygen in plasma by delivering oxygen at increased ambient pressure. Its strongest evidence is for defined indications: selected radiation tissue injury, certain problem wounds, decompression illness, carbon monoxide poisoning and other recognised hyperbaric conditions.

Research has explored ageing-related biomarkers, cognition and recovery. Those findings are interesting and do not establish HBOT as an anti-ageing treatment or show that it extends lifespan.

Where there is a genuine clinical indication, the picture is different and the treatment is appropriate on its own terms. See our pages on hyperbaric oxygen therapy and HBOT for wound recovery.

Framing matters here, because a treatment presented as wellness tends to get less screening than one presented as medicine — and the safety considerations do not change with the framing.

• Middle-ear barotrauma is the commonest adverse effect, which is why equalisation technique is taught and why congestion or recent ear surgery is relevant.
• Untreated pneumothorax is a critical contraindication.
• Some lung conditions, recent ear or sinus surgery, certain medications and claustrophobia all need assessment beforehand.
• Oxygen toxicity is uncommon at treatment pressures but is the reason protocols specify pressure and duration rather than leaving them open.
• Sessions are a course, not a one-off, so the time and cost commitment should be clear before starting.

None of this makes HBOT unsafe in appropriate hands. It does mean the medical history taken beforehand is doing real work, and a provider who does not take one is worth questioning.

Acupuncture has evidence for selected pain conditions and is used by some patients for symptom management, stress-related complaints and supportive care. Evidence quality varies substantially by indication, and it is more persuasive for chronic pain than for most other proposed uses.

There is not good evidence that acupuncture reverses ageing, broadly boosts immunity or extends lifespan. Its reasonable role in a longevity-oriented programme is supportive rather than foundational — which is not a dismissal. Symptom relief and better function are legitimate goals in their own right, and do not need a longevity claim attached to justify them.

One practical caution applies regardless of indication: acupuncture should not delay assessment of a symptom that has not been diagnosed. New pain, unexplained weight loss, neurological symptoms or a change in an existing condition warrant a diagnosis first.

It can be entirely reasonable for one person to have health screening, HBOT for a separate clinical indication and acupuncture for pain. That does not mean the three multiply each other’s effects, and a package presented as a combined protocol is making a claim that each component individually does not support.

There is also an opportunity-cost argument that rarely gets made. Time and money spent on an unproven adjunct are not available for the things that do have outcome evidence — a gym membership, treating hypertension properly, investigating snoring. See sleep apnoea assessment if that last one applies.

• Do not smoke.
• Control blood pressure, cholesterol and diabetes risk.
• Maintain aerobic fitness and strength — resistance training matters for preserving muscle mass with age.
• Eat a largely minimally processed, plant-rich diet with adequate protein.
• Sleep adequately, and investigate persistent snoring or daytime sleepiness.
• Keep vaccinations and evidence-based screening current.
• Maintain social connection and mental health.
• Moderate alcohol.

• What clinical outcome is this supposed to improve?
• Is the evidence based on symptoms, function and disease — or only on a biomarker?
• What happens if I do nothing?
• What are the risks, the opportunity costs and the ongoing maintenance costs?
• Is there a simpler intervention with stronger evidence that I have not done yet?
• Who benefits financially from the recommendation, and is the same party selling both the test and the treatment?
