Want a more accurate blood pressure reading? Try lying down when it’s taken, new study suggests

Lying down while getting your blood pressure taken could result in a more accurate reading, according to new findings presented at the American Heart Association (AHA)’s Hypertension Scientific Sessions 2023 on Saturday in Boston

Researchers found that among people with high blood pressure, the readings more accurately predicted future stroke, heart issues and death when people were lying down compared to those who were sitting, according to a press release from the AHA.

These are preliminary findings and have not yet been published in a peer-reviewed medical journal, the AHA noted.

Senior study researcher Dr. Stephen Juraschek — who’s also a general internist at Beth Israel Deaconess Medical Center in Boston and an associate professor at Harvard Medical School — said in the release that the findings, which he found surprising, could help physicians better identify patients who need treatment.

“Normal” blood pressure for adults is a systolic reading of less than 120 mmHg and a diastolic reading under 80 mmHg, according to the AHA and American College of Cardiology.

Blood pressure fluctuates throughout the day, which is why nighttime measurements are most reliable, Juraschek said.

For this study, researchers analyzed the readings of 11,369 participants in the Atherosclerosis Risk in Communities Study, who had their blood pressure taken both while in a supine position and a seated position.

Those with previous heart issues or stroke were excluded from the study. 

People who had high blood pressure only while lying down had a 53% greater risk of developing coronary heart disease, a 51% higher risk of heart failure, a 62% higher risk of stroke and a 34% greater chance of all-cause mortality — compared to people who had normal blood pressure both while sitting and lying down.

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Center and a Fox News medical contributor, was not involved in the research but shared comment on its findings.

He said this appears to be a “well-done study over many years.”

“There is previous research that high blood pressure taken at night correlates with heart disease and stroke,” he told Fox News Digital. “This is an extension of the same idea.”

When sitting or standing, gravity may lower the blood pressure, resulting in a reading that is not as accurate, Siegel noted.

“Lying down is more consistent with your actual blood pressure, which predicts heart attack and stroke risk, both of which are higher when the blood pressure is high,” the doctor added.

“This study suggests that supine blood pressure may be one explanation, as it has as much impact on long-term cardiovascular outcome as seated blood pressure,” said Dr. Wanpen Vongpatanasin, a professor of medicine at UT Southwestern Medical Center in Dallas, Texas, in the AHA’s press release.

The findings suggest that physicians might miss high blood pressure if they’re only taking the measure from patients who are in a seated position, Juraschek said.

More research is needed to confirm this hypothesis, the doctor added.

One limitation of the study is that patients were lying down for about 20 minutes — which is not a typical occurrence in a doctor’s office.

There could also be other reasons that contributed to the more accurate readings among supine patients, Juraschek noted, including the fact that people are more relaxed while lying down and that fluids are distributed differently in various positions.

“I do think this is a simple enough assessment that people could be empowered to check on their own, and people could use it in screening as well,” Vongpatanasin added.

FDA bans red food dye due to potential cancer risk

The U.S. Food and Drug Administration (FDA) has officially banned red dye — called Red 3, or Erythrosine — from foods, dietary supplements and ingested medicines, as reported by the Associated Press on Wednesday.

Food manufacturers must remove the dye from their products by January 2027, while drug manufacturers will have until January 2028 to do so, AP stated. 

Any foods imported into the U.S. from other countries will also be subject to the new regulation.

RED FOOD DYE COULD SOON BE BANNED AS FDA REVIEWS PETITION

“The FDA is taking action that will remove the authorization for the use of FD&C Red No. 3 in food and ingested drugs,” said Jim Jones, the FDA’s deputy commissioner for human foods, in a statement.

“Evidence shows cancer in laboratory male rats exposed to high levels of FD&C Red No.3,” he continued. “Importantly, the way that FD&C Red No. 3 causes cancer in male rats does not occur in humans.”

      

The synthetic dye, which is made from petroleum, is used as a color additive in food and ingested drugs to give them a “bright cherry-red color,” according to an online statement from the FDA.

The petition to ban the dye cited the Delaney Clause, which states that the agency cannot classify a color additive as safe if it has been found to induce cancer in humans or animals.

The dye was removed from cosmetics nearly 35 years ago due to potential cancer risk.

“This is a welcome, but long overdue, action from the FDA: removing the unsustainable double standard in which Red 3 was banned from lipstick but permitted in candy,” said Dr. Peter Lurie, director of the group Center for Science in the Public Interest, which led the petition effort, as reported by AP.

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, applauded the FDA’s ban.

“It was a long time coming,” he told Fox News Digital. “It’s been more than 30 years since it was banned from cosmetics in the U.S. due to evidence that it is carcinogenic in high doses in lab rats. There needs to be a consistency between what we put on our skin and what we put into our mouths.”

“There needs to be a consistency between what we put on our skin and what we put into our mouths.”

Siegel said he believes the FDA’s decision could be tied to the incoming new head of the Department of Health and Human Services, Robert F. Kennedy Jr.

“They knew it would have happened anyway under RFK Jr.,” he said. “It is already banned or severely restricted in Australia, Japan and the European Union.”

“Food safety is the number one priority for U.S. confectionery companies, and we will continue to follow and comply with FDA’s guidance and safety standards.”

As bird flu spreads, CDC recommends faster 'subtyping' to catch more cases

As bird flu spreads, CDC recommends faster 'subtyping' to catch more cases

As cases of H5N1, also known as avian flu or bird flu, continue to surface across the U.S., safety precautions are ramping up.

The U.S. Centers for Disease Control and Prevention (CDC) announced on Thursday its recommendation to test hospitalized influenza A patients more quickly and thoroughly to distinguish between seasonal flu and bird flu.

The accelerated “subtyping” of flu A in hospitalized patients is in response to “sporadic human infections” of avian flu, the CDC wrote in a press release.

“CDC is recommending a shortened timeline for subtyping all influenza A specimens among hospitalized patients and increasing efforts at clinical laboratories to identify non-seasonal influenza,” the agency wrote.

“Clinicians and laboratorians are reminded to test for influenza in patients with suspected influenza and, going forward, to now expedite the subtyping of influenza A-positive specimens from hospitalized patients, particularly those in an intensive care unit (ICU).”

The goal is to prevent delays in identifying bird flu infections and promote better patient care, “timely infection control” and case investigation, the agency stated.

These delays are more likely to occur during the flu season due to high patient volumes, according to the CDC.

Health care systems are expected to use tests that identify seasonal influenza A as a subtype – so if a test comes back positive for influenza A but negative for seasonal influenza, that is an indicator that the detected virus might be novel.

“Subtyping is especially important in people who have a history of relevant exposure to wild or domestic animals [that are] infected or possibly infected with avian influenza A (H5N1) viruses,” the CDC wrote.

In an HHS media briefing on Thursday, the CDC confirmed that the public risk for avian flu is still low, but is being closely monitored.

The agency spokesperson clarified that this accelerated testing is not due to bird flu cases being missed, as the CDC noted in its press release that those hospitalized with influenza A “probably have seasonal influenza.”

Niels Riedemann, MD, PhD, CEO and founder of InflaRx, a German biotechnology company, said that understanding these subtypes is an “important step” in better preparing for “any potential outbreak of concerning variants.”

“It will also be important to foster research and development of therapeutics, including those addressing the patient’s inflammatory immune response to these types of viruses – as this has been shown to cause organ injury and death during the COVID pandemic,” he told Fox News Digital. 

Since 2022, there have been 67 total human cases of bird flu, according to the CDC, with 66 of those occurring in 2024.

The CDC recommends that people avoid direct contact with wild birds or other animals that are suspected to be infected. Those who work closely with animals should also wear the proper personal protective equipment (PPE).
