Spotting a misleading health headline

ByRaymond Hackland

Evidence label: Well studied (as a research method) This label describes the reading method. The studies used as examples keep their own labels, and none of them is a promise of what a practice will do for you.

In short

What this is: Four real headlines about Qigong, tai chi and sound, each traced back to the study behind it and read with the five questions from How to read a health study in 5 minutes and the ladder from Study types explained: from anecdote to meta-analysis. It is part of our series “Reading the Evidence”.

What the evidence says: Researchers have studied how health news goes wrong. In a large study of university press releases, exaggerated advice, causal claims and leaps from animals to humans were common, and news stories mostly repeated what the press release already said [1]. Reviewers who graded thousands of health news stories found the same gaps again and again: numbers, harms, quality of evidence and alternatives were often missing [2, 3].

What it means for your practice: A headline is an advertisement for an article, which is itself a summary of a press release, which is a summary of a study. Each step can add certainty that was never in the study. Going back to the study takes a few minutes, and it is usually where the real story is.

What science says

Label: Well studied (as a research method). Each example keeps its own label.

Why headlines drift

Most health headlines are not invented by the journalist. In 2014, Petroc Sumner and colleagues compared 462 press releases on health-related research from 20 leading UK universities with the published papers and with 668 news stories based on them [1]. They looked for three kinds of exaggeration that go beyond the paper:

  • advice to readers to change what they do (in 40% of the press releases),
  • causal claims drawn from studies that could only show a correlation (33%),
  • inference to humans from animal or cell research (36%).

When the press release exaggerated, most news stories did too: 58% for advice, 81% for causal claims and 86% for animal-to-human leaps. When the press release did not exaggerate, the rates in the news were much lower: 17%, 18% and 10% [1]. The study was itself observational, but its message is plain: much of the distortion is already there before the journalist starts typing. The authors also found little evidence that exaggeration got a story more coverage [1].

A second useful tool comes from HealthNewsReview.org, a US project that graded health news stories against ten criteria between 2006 and 2018. The project lost its funding at the end of 2018 and the site has since been taken down, so we cite its criteria from an archived copy [2]. Among the ten questions: does the story quantify the benefits, explain the harms, grasp the quality of the evidence, use independent sources and name conflicts of interest, compare the new approach with existing alternatives, and does it rely mainly on a news release? [2] In its first 500 reviews, between 62% and 77% of stories failed to cover costs, harms, benefits, the quality of the evidence or the existence of other options adequately [3]. For press releases, the project also flagged sensational words: “breakthrough”, “cure”, “game-changer”, “miracle”, and “this might/may/could lead to” [2].

Here are our five questions again, from How to read a health study in 5 minutes:

  1. Who, and how many?
  2. Compared with what?
  3. What was measured?
  4. How big, and how sure?
  5. What else agrees?

And one more, borrowed from Study types explained: from anecdote to meta-analysis: which rung of the ladder is this? A personal story, a case report, a lab or mechanism study, a cross-sectional snapshot, a cohort, a non-randomised comparison, a randomised trial or a systematic review each carry a different weight.

Now to the headlines.

Example 1: “Proven to lower blood pressure”

On 18 February 2026 the American College of Cardiology issued a press release headlined “Ancient Mind-Body Practice Proven to Lower Blood Pressure in Clinical Trial” [4]. A day later, HealthDay’s story ran as “Ancient Chinese Practice Lowers Blood Pressure As Well As Medications, Walking Program, Clinical Trial Shows” [5]. The practice is Baduanjin, the Eight-Section Brocade, and the study is real and well designed: the BLESS trial, published in the Journal of the American College of Cardiology [6]. Everything we say about the trial rests on its published abstract and its registry entry; the full paper is behind a paywall. This is a good example precisely because the research looks solid. The question is whether the headlines say more than the trial did.

Who, and how many? 216 adults aged 40 and over, mean age 57, about two-thirds women, from seven communities. Their blood pressure was at the upper end of normal: 130 to 139 mm Hg systolic and/or 85 to 89 mm Hg diastolic [6]. The paper calls this “high-normal”; the press release notes that under the American guideline the same systolic range counts as stage 1 hypertension [4, 6]. The label depends on which guideline you use, which is worth knowing when a news story describes the participants as people “with high blood pressure” [5]. In fact, people already diagnosed with hypertension or taking blood-pressure drugs were excluded [6].

Compared with what? People were randomly assigned to Baduanjin (108), to self-directed exercise of their own choice (54) or to brisk walking (54), for a year [6]. That is the right kind of comparison: randomised, with active control groups. The trial was “open-label”, so everyone knew which group they were in, but the outcome was assessed blind and was measured by a 24-hour blood pressure monitor rather than by asking people how they felt [6]. That matters, because a lack of blinding tends to inflate results mainly for subjective outcomes [7].

What was measured? Blood pressure. That is a surrogate outcome: a measurement that stands in for what people actually care about, here heart attacks and strokes. Blood pressure is one of the better surrogates, but a surrogate is still not the outcome itself, and medicine has learned this the hard way. In a famous case from the late 1980s, drugs that suppressed irregular heartbeats after a heart attack, a sensible-looking surrogate, turned out to increase deaths in a large trial: 7.7% of patients on two of the drugs died, against 3.0% on placebo [8, 19]. The BLESS trial did not measure heart attacks or strokes, and at this size and length it could not have done so.

How big, and how sure? Compared with self-directed exercise, 24-hour systolic blood pressure fell by 3.1 mm Hg more at 12 weeks (95% confidence interval 0.2 to 5.9 mm Hg) and by 3.3 mm Hg more at 52 weeks (0.3 to 6.3 mm Hg) [6]. Both results are statistically significant, and the ranges are wide: the true difference could be anywhere from a fraction of a millimetre to about six. Against brisk walking at 52 weeks, there was no significant difference: 0.7 mm Hg lower with Baduanjin, with a range from 3.9 lower to 2.6 higher [6]. There was no medication group at all. The “as well as medications” in the HealthDay headline comes from the press release, which compares the size of the effect with reductions “seen with some first-line medications” in other trials [4, 5]. That is a comparison across different studies, not something this trial tested.

What else agrees? One trial is one trial. Reviews of tai chi and Qigong report lower blood pressure in people with hypertension, with certainty ratings that range from high to low depending on the review, as our article Qigong and tai chi: what systematic reviews say explains.

Which rung? A randomised controlled trial, high on the ladder. The headlines are right that the result was positive. What they add is the word “proven” for a single trial with a surrogate outcome, and a comparison with medication that the trial never made. An example of a fairer headline, keeping to what the trial reports, might read: “In a year-long trial, blood pressure fell slightly more with Baduanjin than with self-chosen exercise, with no clear difference from brisk walking.”

Label of the example: Early evidence (one well-designed trial, one surrogate outcome).

Example 2: “528 Hz repairs DNA”

This claim lives mostly on wellness pages and in video titles. One long-running spiritual guide lists the Solfeggio tones and says “528Hz – attracts love, repairs DNA, and has the potential to bring about miracles” [9]. A long video on YouTube is titled “432 Hz + 528 Hz DEEPEST Healing Music l DNA Repair & Full Body Healing l Let Go Of Negative Energy” [10]. Neither cites a study for the DNA claim.

Where the claim comes from. As our article Solfeggio frequencies: where they come from and what the evidence says shows, the numbers were first published in a 1999 book by Leonard Horowitz and Joseph Puleo, and the book’s source for DNA repair is a personal communication, not an experiment [11]. That is the bottom of the ladder: a story, retold.

The studies people point to. Two small studies are usually cited for 528 Hz, and neither measured DNA repair in people.

  • A cell study. Babayi and Riazi exposed human astrocytes, a type of brain support cell, to ethanol in a dish and then to a 528 Hz tone. About 20% more cells survived, and a marker of cell stress fell [12]. The paper mentions “DNA repair” only as an earlier claim in its background, not as something it measured, and it tested no other frequency, so it cannot show that 528 Hz is special. On the ladder, this is a laboratory study: it can suggest how something might work, but it is not an outcome in people.
  • A study in nine people. Akimoto and colleagues had nine healthy adults listen for five minutes to soothing piano music tuned so that its scale includes 528 Hz, and on another day to music at standard 440 Hz tuning. They measured stress markers in saliva (cortisol, chromogranin A, oxytocin), heart-rhythm signals and mood questionnaires [13]. After the 528 Hz version, cortisol fell and oxytocin rose significantly compared with before listening; after the 440 Hz version no saliva marker changed significantly. The two versions were not compared directly with each other [13]. Nothing about DNA was measured. The authors themselves write that the various effects ascribed to Solfeggio frequencies have no scientific basis [13].

Run the five questions over Akimoto’s study and you get: nine healthy people; compared with music at standard tuning, on a different day, and only against each version’s own baseline; measured stress hormones, a surrogate, not health; a short-term change in a very small group; and no independent replication of this design that we know of. That is an interesting pilot, and our article How to read a health study in 5 minutes uses it as an example. It is a long way from “repairs DNA”.

Label of the example: Speculative (the health claims made for 528 Hz).

Example 3: from mouse to “Alzheimer’s symptoms”

In March 2019, MIT News published a story headlined “Brain wave stimulation may improve Alzheimer’s symptoms” [14]. Read on, and the subheading says “Noninvasive treatment improves memory and reduces amyloid plaques in mice.” The underlying paper in Cell found that mice bred to develop Alzheimer’s-like changes, exposed to 40 Hz tones for an hour a day for a week, had less amyloid in parts of the brain and performed better on memory tasks [14, 15].

This is careful laboratory science, and the headline even says “may”. But the word “mice” is missing from it, and many readers stop at the headline. It is exactly the leap Sumner’s team counted [1]. One more thing the story leaves out: the paper’s conflict-of-interest statement says two of its authors are co-founders of a company, Cognito Therapeutics, and a third author owns shares in it [15]. How often do even prominent animal findings hold up in people? A study of 76 highly cited animal experiments found that about a third (37%) were later confirmed in human randomised trials, 18% were contradicted, and the rest had not been tested in people at all [16].

For practitioners who work with sound, this example is a reminder in both directions. Sound clearly does things in the brain worth studying. But “40 Hz tones reduced amyloid in mice” tells you nothing yet about chanting, humming, tuning forks or the six sounds in people. Our article Binaural beats: do brainwaves entrain? looks at a similar question in humans.

Label of the example: Speculative (as a claim about people; the mouse findings are laboratory results).

Example 4: “Want to live longer? Try tai chi”

That is the headline of a Reuters story on a Vanderbilt University study of Chinese men who practised tai chi, as run by The Denver Post on 23 July 2013 [17]. The study behind it is real and large: 61,477 men in the Shanghai Men’s Health Study, followed for about five and a half years, during which 2,421 died [18]. Men who practised tai chi had a 20% lower risk of death than men who did not exercise (hazard ratio 0.80, 95% confidence interval 0.72 to 0.89), after the researchers adjusted for other factors they had measured. Walking (0.77) and jogging (0.73) showed similar associations [18].

Correlation, not cause. This is a cohort study, step 4 on our ladder. Nobody was assigned to tai chi; the men chose it. Men who are healthy enough, and have the time, to practise regularly may differ from those who don’t in ways no adjustment fully captures. The authors chose their words with care: tai chi “is associated with” lower mortality [18]. The story itself reports that the researcher said her study could not prove tai chi was responsible, and it quotes an independent expert on the same point [17]. The headline drops those caveats and turns the association into advice, which is the most common exaggeration in Sumner’s study [1].

Relative and absolute. “20% lower risk” is a relative figure. It tells you nothing until you know the starting risk. The paper’s own table shows why the starting point matters. During follow-up, 3.3 in 100 men who did not exercise died (1,306 of 39,630), and so did 6.2 in 100 men who practised tai chi (602 of 9,726). The tai chi men died more often in raw numbers, because exercisers were older and more often had heart disease, diabetes or high blood pressure. The “20% lower” appears only after the researchers adjusted for those differences [18]. As a rough illustration only, not a result the paper reports: on a starting risk of 3.3 in 100, a 20% lower risk would be about 2.6 in 100, a difference of less than one man in a hundred over about five and a half years. In one early study of news coverage of medicines, only 18 of 124 stories that gave numbers for benefits gave both the relative and the absolute figures [20].

What else agrees? Walking and jogging showed much the same association [18]. So whatever lies behind it, the study cannot single out tai chi: it points at regular exercise in general, not at anything special about tai chi.

Label of the example: Early evidence (an association in one cohort; not evidence of cause).

Six warning signs on one card

  • “Proven”, “cure”, “breakthrough”, “miracle”. One study rarely proves anything. Check which rung of the ladder it sits on.
  • No group, or the wrong group. “Compared with what?” If the headline compares with medication, check whether the trial had a medication group.
  • A body signal in place of an outcome. Blood pressure, cortisol, amyloid and brainwaves are surrogates. Ask what people actually experienced.
  • A relative number on its own. “20% lower” or “twice as likely”: ask “out of how many?”
  • “Linked to” turned into “do this”. Observational studies show associations. Advice to change what you do needs more.
  • A missing “in mice” or “in cells”. Look for the species and the dish before you look for the result.

What tradition says

Label for this section: Tradition only.

Headlines about Qigong often lead with age: “ancient”, “800 years”, “thousands of years”. Age is a question for history. The forms practised today have long histories, but the Health Qigong versions of Baduanjin and Liu Zi Jue, for example, were standardised only in the early 2000s, as our article Health Qigong: how China’s standard forms were made describes. A practice that has lasted has clearly been valued, and that deserves respect, but its long survival is not a comparison group, and it belongs to tradition, not to the evidence ladder.

Equally, a headline that a study “found no effect” says nothing about what a practice means in its tradition.

Where popular claims go beyond the evidence

Label for this section: Speculative.

“It was published, so it’s true.” Both the BLESS trial and the 528 Hz cell study were published [6, 12]. One was a randomised trial with 216 people in a leading cardiology journal; the other was a single experiment on cells in a dish. Being published tells you that a paper exists, not how much it can carry.

“Natural means no side effects.” The journal’s editor was quoted in the press release praising an effect “achieved without medication, cost or side effects” [4]. The BLESS trial found no significant difference in adverse events between the three groups [6]. That is a finding about one trial of a gentle exercise in adults with high-normal blood pressure, not a general rule. HealthNewsReview asked every story to explain harms for a reason [2]. If you have a health condition, the practice still has to suit you.

“Scientists confirm…” Look for which scientists, and whether they ran the study or are commenting on it. The HealthNewsReview criteria ask whether a story uses independent sources [2]. In Example 1, the only voices quoted in the HealthDay story, both taken from the press release, were the study’s senior author and the editor of the journal that published it [4, 5].

“This frequency heals…” No study we know of has shown that a particular audible frequency acts on a particular organ or on DNA in people. Our articles 432 Hz vs 440 Hz: history, myths and evidence and Solfeggio frequencies: where they come from and what the evidence says go through the studies that do exist.

How this relates to the Six Healing Sounds, Qigong and neigong

Label for this section: Early evidence (research on Liu Zi Jue and Baduanjin) · Tradition only (qi, organ pairings, neigong concepts).

Claims about our own practices follow the same patterns. A typical one, which the first article in this series uses as its worked example, is “Studies show the Six Healing Sounds improve lung function”. It leaves out who was studied (mostly people with stable COPD), compared with what (usual care) and how sure (the review authors themselves point to methodological bias and placebo effects). How to read a health study in 5 minutes walks through it step by step. The organ pairings of the six sounds and the idea of qi are traditional concepts; no headline can confirm or refute them, and a headline that claims to has gone beyond any study.

How I read these headlines

I use tones and tuning forks in my sessions, and on my main site each of the six sounds is paired with a Solfeggio tone, described there as “an invitation to resonance, not a health claim”. That is why the 528 Hz example matters to me. A tone can be a beautiful musical choice without any study behind it, and I would rather say that plainly than borrow a claim the research doesn’t support. When a Qigong headline sounds too good, the five questions are how I want this Knowledge Hub to read it: back to the study, which is often more modest, and more interesting, than the headline.

If you have a health condition, please read Who should be careful with breathing practices before you start.

Resonance Heritage Qi is a personal, music-assisted practice inspired by Liu Zi Jue: connected to it, not a replacement for the traditional form or for study with a teacher of that tradition. No study has tested it, and we make no claims about its effects. Where we use music, tuning forks or particular tones in sessions, these are aesthetic choices and an invitation to listen closely, not health claims. Claims about specific “healing frequencies” are covered in Solfeggio frequencies: where they come from and what the evidence says.

Next in the series: Why one study isn’t proof (coming soon), on sample size, replication and p-values in plain words. A glossary of research terms is also planned.
