Simple nightly habit linked to healthier blood pressure, study suggests
NEWYou can now listen to Fox News articles!
A consistent bedtime may play a meaningful role in lowering blood pressure, according to new research examining how sleep timing affects cardiovascular health.
While most people think primarily about getting enough hours of sleep, experts say when you sleep also has an important effect on heart health.
Dr. William Lu, medical director at Dreem Health in San Francisco, told Fox News Digital that sleep duration and sleep timing work together, and that consistency is a key part of supporting cardiovascular wellness.
EXPERTS REVEAL EXACT BEDTIME THAT COULD PREVENT LATE-NIGHT ‘SECOND WIND’ INSOMNIA
“Both matter, but growing evidence shows regularity — going to sleep and waking at roughly the same times night-to-night — is an independent predictor of cardiovascular risk even after accounting for total sleep time,” Lu said.
Recent findings have supported that connection. In a study published in the journal Sleep Advances, adults with high blood pressure who kept a consistent bedtime for two weeks saw modest but meaningful improvements in their readings, even though they did not sleep longer hours.

Participants reduced their night-to-night bedtime variability from about 30 minutes to only a few minutes, and researchers said that simple change helped restore healthier blood pressure overnight.
Even a modest nighttime drop in systolic pressure can lower cardiovascular risk, experts say.

The concept is supported by research into circadian rhythms and the body’s natural blood-pressure patterns.
“Consistent bed and wake times keep your internal circadian clock synchronized to Earth’s day-night cycle,” Lu said.

A steady sleep schedule helps the body release important hormones, like melatonin and cortisol, at the right times, which supports the natural rise and fall of blood pressure throughout the day and night, according to the doctor.

Disruptions in sleep timing can affect blood pressure more quickly than many people realize, Lu warned. While some people assume that shifting their bedtime on weekends or staying up late occasionally has little impact, the expert said the body responds almost immediately.

For people trying to build a more consistent sleep routine, Lu recommends starting with the morning wake-up time.
“Start with a fixed wake time every day, including weekends, and anchor the schedule with morning light exposure — then set a consistent bedtime that gives you enough sleep before that wake time,” he advised. “Pick a wake time you can sustain and get 30 minutes of morning light after waking up.”

He also recommends adding a brief wind-down routine before bed and cutting back on stimulants and screen use in the evening.
Improving sleep timing is a low-risk change that may help lower blood pressure, Lu said, adding that consistent bedtimes should be used in addition to anti-hypertensive medications, not as a substitute.
Potential limitations
The study did have some limitations, the researchers acknowledged.
The sample size was relatively small, consisting of 11 middle-aged adults with obesity and hypertension. It was also a two-week period, which means researchers could measure only short-term changes.

The study also lacked a control group or randomization, so it couldn’t prove that the blood-pressure improvements were caused by more consistent bedtimes or by other lifestyle factors, such as diet, stress or medication changes. Larger, longer-term studies are needed to confirm the findings.
Anyone considering changes to their sleep schedule for blood-pressure benefits should first speak with a doctor.

Common vaccine slashes Alzheimer’s disease risk when dose is increased
NEWYou can now listen to Fox News articles!
A new, stronger flu shot could slash Alzheimer’s risk in half, according to new data.
The study, led by researchers at the University of Texas Health Science Center at Houston (UTHealth), found that adults 65 and older who received a high-dose influenza vaccine had a significantly lower risk of developing Alzheimer’s disease compared to those who received the standard dose.
The immune system naturally weakens with age, making older adults less responsive to standard vaccines. To combat this, the Centers for Disease Control and Prevention recommends a high-dose flu vaccine for people over 65. This version is approximately four times stronger than the standard shot.
ONE TYPE OF OLIVE OIL HAS A SURPRISING EFFECT ON BRAINPOWER DURING AGING
Alzheimer’s disease, a brain disorder that slowly destroys memory and thinking skills, affects more than 6 million Americans, most of them age 65 or older.
Dr. Marc Siegel, a Fox News senior medical contributor, weighed in on the impact of the flu shot on Alzheimer’s risk.

As the vaccine directly affects the immune system, it is possible that this interaction could decrease inflammation in the body and “thereby indirectly decrease Alzheimer’s risk,” Siegel, who was not involved in the research, told Fox News Digital.
“Flu shots and their components do not cross the blood-brain barrier, meaning they aren’t directly affecting brain cells.”
“We can’t conclude from this that it is the flu shot itself that causes the effect.”
“I was stunned that, as a physician, I didn’t know a higher dose was offered,” lead study author Paul Schulz, professor of neurology at McGovern Medical School at UTHealth, said in a press release.
Schulz also led a previous study linking general flu vaccination to a 40% reduction in Alzheimer’s risk.
While the previous research had already linked general flu vaccination to a reduction in Alzheimer’s risk, this new study looked specifically at the strength of the dose.
POPULAR DIET TIED TO LOWER DEMENTIA RISK FOR SOME GROUPS, STUDY REVEALS
“The public health department had seen our vaccine research and asked if I could come down to talk to them about it,” said Schulz. “We went through the findings, and they asked if there was a difference with different dosages; I was confused.”

After sorting through data from nearly 200,000 older adults, the team found the adults who received the high-dose vaccine had a lower risk of Alzheimer’s than those who received the standard dose.
Adults in the high-dose group had an almost 55% lower risk than those who weren’t vaccinated, significantly outperforming standard-dose protection.

The protective effect of the high-dose vaccine was even more pronounced in women compared to men, although both groups saw significant benefits.

This study shows a link, not a cause, the researchers noted.
Experts can’t say for certain that the flu shot itself stopped Alzheimer’s because people who get high-dose vaccines might also have other healthy habits, like better diets or more frequent check-ups.
The study focused on people over 65, so it’s unclear whether getting these shots earlier in life would provide the same level of protection. (iStock)
The researchers also looked at medical records after the fact, rather than following two controlled groups in real time, which can sometimes result in missing information or biases.
“This is not a cause/effect study,” Siegel reiterated. “We can’t conclude that the flu shot itself causes the effect; it could be something about the people who decide to take this shot.”

The study also focused on people over 65, so it’s unclear whether getting these shots earlier in life would provide the same level of protection.
“This needs to be further studied, but it is already certainly another reason to take a flu shot,” Siegel added.

Woman discovers missing nose ring traveled to her lungs, causing month-long cough
NEWYou can now listen to Fox News articles!
A TikToker in Mexico thought her cough that wouldn’t go away was just a reaction to the changing weather. Instead, it was her own nose ring, lodged deep within her lungs.
The 26-year-old, Monica Deyanira Cabrera Barajas, recently went viral on TikTok, amassing 4.7 million views after revealing the freak medical accident.
In videos, she shared that the stray accessory sat a mere 0.5 millimeters from her aorta, Jam Press reported.

Deyanira, who has a large number of piercings, didn’t initially notice the jewelry was missing. It wasn’t until she developed a “chronic cough” lasting over a month that she went to see a doctor.
“The only theory I have, which I told the pulmonologist, is that I fell asleep, the little ball fell out, and that was it,” Deyanira told creatorzine.com.
What was supposed to be a routine 20-minute extraction turned into a high-stakes medical procedure. (Jam Press)
“I was lying on my back, I didn’t realize, and that’s how I messed up.”

What was supposed to be a routine 20-minute extraction turned into a high-stakes medical procedure. During the initial attempt, surgeons were unable to budge the object because it had already begun attaching to her internal tissue.
“It ended up taking an hour and 20 minutes, and they still couldn’t remove it because it was attached to my body,” she said, according to the Jam Press report.

Facing a second, more invasive surgery and the risk of a fatal hemorrhage, Deyanira prepared for the worst. The night before the surgery, she wrote a farewell letter to her loved ones.

“I was honestly thinking, ‘I’m going to die,’” she said. “It’s a horror I wouldn’t wish on anyone.”

The woman’s surgeon was equally stunned by how close the metal was to her heart. According to Deyanira, the doctor told her, “It seems God takes care of his creatures.”
If the metal had punctured her lung or heart before doctors discovered it, Deyanira said she likely would have died from a lung collapse or perforated aorta.

Now, the TikToker says her days of septum rings are over.
After the ordeal, Deyanira said she’s permanently done with piercings. (Jam Press)
“I love piercings, and I really liked my septum piercing, but in my case, I wouldn’t get it again because of the terror I experienced,” she said.
