For women over 60, here is the number of daily steps needed to protect heart health
We’ve all heard the widespread recommendation of hitting 10,000 steps per day for optimal health, but some groups — such as women over age 60 — may not need that many.
That’s according to a new study published in JAMA Cardiology, which found that women between the ages of 63 and 99 only needed an average of 3,600 steps per day to reduce their heart failure risk by 26%.
“[This was] after accounting for differences in age, race and ethnicity, and clinical factors known to increase one’s risk of heart failure,” said lead author Michael J. LaMonte, PhD, research professor of epidemiology and environmental health in UB’s School of Public Health and Health Professions, in a statement to Fox News Digital.

“That is far fewer than the often targeted 10,000 steps per day,” he noted.
Researchers from University at Buffalo in New York observed 6,000 U.S. women between ages 63 and 99, gathering data about their physical activity, sedentary time and heart health.

During a period of 7½ years, there were 407 cases of heart failure in the group.
The risk was found to be 12% to 17% lower for every 70 minutes of light activity (housework, self-care and other daily tasks) and 30 minutes of moderate- to vigorous-intensity activity (climbing stairs, doing yard work, walking or jogging).

For every 90 minutes of sedentary time, the heart failure risk increased by 17%, the researchers found.
To measure their physical activity, the participants wore a tracking device on their hips for a week.

“Even the lighter-intensity activities of daily living and walking seem to be associated with a lower risk of heart failure in older women,” said LaMonte.
“So, our data suggest that physical activity amounts and intensity below what’s currently recommended in public health guidelines could be beneficial for heart failure prevention in later life.”

The study evaluated risk for two different types of heart failure, including heart failure with preserved ejection fraction (HFpEF).
With this condition, also known as diastolic heart failure, the heart muscle contracts as it should, but the left ventricle remains stiff and prevents the heart from filling properly with blood, according to the American Heart Association’s website.

“HFpEF is the most common form of heart failure seen in older women and among racial and ethnic minority groups, and at present there are few established treatment options — which makes primary prevention all the more relevant,” LaMonte told Fox News Digital.
“This type of heart failure is increasingly common in women, older adults and racial-ethnic minority groups,” Lamonte told Fox News Digital.

“Unfortunately, there presently are no established therapies to treat this heart failure subtype, making its prevention that much more important. The relevance only increases with population aging, as women are expected to outnumber men in the 80+ group over the coming decades.”
LaMonte added, “The potential for light intensity activities of daily life to contribute to the prevention of HFpEF in older women is an exciting and promising result for future studies to evaluate in other groups, including older men.”

The risk of heart failure, including HFpEF, became “significantly lower” at around 2,500 steps per day, according to the release.
The risk dropped by 25% to 30% at the 3,600-step mark.
Potential limitations
There were some limitations of the study, the lead researcher noted.
“The observational study design requires caution against interpreting causation on the basis of associational results,” LaMonte told Fox News Digital.
“We only had a single accelerometer measure, and activity habits could change during follow-up, so repeat measures would be preferable.”
“Even lighter-intensity activities of daily living and walking seem to be associated with a lower risk of heart failure in older women.”
The researchers also did not have newer biomarkers of cardiac injury and volume overload, he said, which would have resulted in richer analysis of activity that may lower heart failure risk.
“Our cohort is older, postmenopausal women, so other studies need to confirm these results in men and younger individuals,” LaMonte said.
Importance of exercise for older women
Dr. Bradley Serwer, a cardiologist and chief medical officer at VitalSolution, a Cincinnati, Ohio-based company that offers cardiovascular and anesthesiology services to hospitals, was not involved in the study but noted the importance of physical activity for heart health.

“Regular exercise can help improve cardiovascular fitness by improving peripheral circulation, improving vascular tone, and controlling comorbidities such as high blood pressure, diabetes and hypercholesterolemia,” he told Fox News Digital.

“It is important to stay active both mentally and physically, especially over the age of 50.”
Ideally, senior women should aim for a mixture of aerobic and weight-lifting exercises on a regular basis, Serwer said.
For those who are over 50, he warned that high-impact exercises, such as running, may lead to overuse injuries.
“Low-impact activities such as cycling, walking, swimming or yoga can be highly beneficial,” he recommended.
“A simple message for older adults is, ‘Sit less and move more.’”
For those who haven’t exercised in a while, Serwer said it’s important to see a doctor to make sure they are healthy enough to start a fitness program.
“Once it’s determined you are healthy enough for exercise, I recommend starting slow and gradually building up,” he said. “Sometimes it is helpful to hire a personal trainer or join a gym with an exercise physiologist.”

LaMonte added, “A simple message for older adults is, ‘Sit less and move more.’”
Moving around the home, caregiving and walking are beneficial sources of movement for cardiovascular health in later life, he noted.

“For those capable and interested in doing moderate-intensity activities, greater benefit is likely gained — but movement doesn’t have to be fancy or planned,” he said.
“Just try to be active in daily life and try to interrupt prolonged sitting with a little walking.”

A popular class of weight-loss drugs may prevent life-threatening cardiac complications by opening microscopic blood vessels that often remain blocked after a heart attack, according to a study published this week in Nature Communications.
The research, led by the University of Bristol and University College London, identified a biological brain-gut-heart signaling pathway.
This discovery appears to explain how GLP-1 drugs — which mimic glucagon-like peptide-1, a hormone that helps regulate blood sugar and appetite — protect heart tissue from a condition known as “no-reflow.”
“In nearly half of all heart attack patients, tiny blood vessels within the heart muscle remain narrowed, even after the main artery is cleared during emergency medical treatment,” Dr. Svetlana Mastitskaya, the study’s lead author and a senior lecturer at Bristol Medical School, said in a press release.
“This results in a complication known as ‘no-reflow,’ where blood is unable to reach certain parts of the heart tissue.”

This lack of blood flow increases the risk of heart failure and death within a year. GLP-1 medications could prevent this, according to the researchers.
How it works
When the GLP-1 hormone is released in the gut or administered as a drug, it sends a signal to the brain, which then sends a signal to the heart that switches on special potassium channels in tiny cells called pericytes.

When these channels open, the pericytes relax, which allows the small blood vessels (capillaries) to widen and improve blood flow to the heart muscle, the researchers noted.

The new study used animal models and cellular imaging to track how GLP-1 interacts with heart tissue. When the researchers removed the potassium channels, the drugs no longer protected the heart — confirming they play a key role.
The findings suggest that existing GLP-1 medications, already used for type 2 diabetes and obesity, could be repurposed as emergency treatments. (iStock)

The researchers noted several limitations, including that the study relied on animal models.
Clinical trials are necessary to determine whether the brain-gut-heart pathway operates with the same timing and efficacy in humans.
While the study highlights the drug’s immediate benefits during a heart attack, it des not establish whether long-term use of these drugs provides a pre-existing level of protection. (iStock)

Collagen supplements have exploded in popularity, touted as everything from an anti-aging miracle to a muscle recovery booster.
But a sweeping new review conducted by U.K. researchers suggests that while collagen may help improve skin elasticity and ease arthritis pain, it does little for athletic performance or wrinkle reduction.
Researchers from Anglia Ruskin University analyzed 16 systematic reviews and 113 randomized controlled trials involving nearly 8,000 participants worldwide, which they say is the most extensive evaluation of collagen’s health effects to date.
The review found consistent evidence that collagen supplementation improves skin elasticity and hydration over time and provides significant relief from osteoarthritis-related joint pain and stiffness, according to findings published in Aesthetic Surgery Journal Open Forum.

The researchers, however, did not find meaningful improvements in post-exercise muscle recovery, soreness or tendon mechanical properties (strength, springiness and stretch resistance).
“Collagen is not a cure-all, but it does have credible benefits when used consistently over time, particularly for skin and osteoarthritis,” co-author Lee Smith, professor of public health at Anglia Ruskin University, said in a statement.
EXPERIMENTAL SERUM SHOWS PROMISE IN REVERSING BALDNESS WITHIN 20 DAYS
“Our findings show clear benefits in key areas of healthy aging, while also dispelling some of the myths surrounding its use,” Smith added.
Collagen, the most abundant protein in the body, supports skin, bones, tendons, cartilage and connective tissue, according to experts. Natural collagen production begins to drop in early adulthood and declines more sharply with age.

The review found that long-term collagen supplementation was linked to improved skin firmness and hydration, but did not help skin roughness — a proxy for visible wrinkles.
Benefits appear to accumulate gradually, suggesting that collagen should not be viewed as an “anti-wrinkle ‘quick fix,’ but as a foundational dermal support for individuals seeking holistic skin maintenance,” the researchers said.
“If we define anti-aging as a product or technique designed to prevent the appearance of getting older, then I believe our findings do support this claim for some parameters,” Smith told the BBC. “For example, an improvement in skin tone and moisture is associated with a more youthful-looking appearance.”
Collagen supplementation was linked to reduced pain and stiffness in people with osteoarthritis, with stronger benefits seen over longer periods of use, and showed modest improvements in muscle mass and tendon structure that may support healthy aging.

However, it did not show meaningful results when used as a fast-acting sports performance supplement, and evidence for benefits related to cholesterol, blood sugar, blood pressure and oral health was mixed or inconclusive.
Dr. Daniel Ghiyam, a California-based physician and longevity specialist, said the findings align with what he sees in clinical practice.

“Collagen is a targeted support tool, not a foundation of health or performance,” Ghiyam, who was not involved in the study, told Fox News Digital. “When marketed that way, it makes sense. When marketed as a cure-all, it doesn’t hold up to the data.”
The authors noted that while many previous collagen studies have received financial support from the supplement industry, the current review did not receive industry funding.

The team called for more high-quality clinical trials examining long-term outcomes, optimal dosages and differences between collagen sources, such as marine, bovine and plant-based alternatives.
Among its limitations, the review could not determine whether certain forms of collagen work better than others or what the optimal regimen should be.

While the review included randomized controlled trials, the quality of the studies varied, with newer research generally showing stronger results.
Experts say more data and studies are needed to build on the findings. They also noted that diet plays a crucial role in skin health.

Dr. Erum Ilyas, a Pennsylvania-based dermatologist and chair of dermatology at Drexel University College of Medicine, noted that the review analyzed previously published meta-analyses rather than generating new primary data.

“At this time, I have not seen sufficiently strong independent evidence to routinely recommend collagen supplements to my patients,” Ilyas, who was not involved in the review, told Fox News Digital.
“Although some studies show modest improvements in markers such as hydration and elasticity, there remains limited independent, biopsy-confirmed evidence demonstrating sustained increases in dermal collagen content,” she added.
Fox News Digital has reached out to the researchers for comment.
