Menopause Before Age 40 Tied to Higher Lifetime Heart Disease Risk: Study

A new study published in JAMA Cardiology reveals that women who experience premature menopause—before age 40—face a significantly higher lifetime risk of Coronary Heart Disease. The research found that these women are about 40% more likely to develop heart disease compared to those who reach menopause at a later age, highlighting menopause timing as a critical factor in long-term cardiovascular health.

Led by Priya Freaney of Northwestern University, the study analyzed data from over 10,000 postmenopausal women aged 55 to 69. Participants were drawn from six long-term U.S. cohorts within the Cardiovascular Disease Lifetime Risk Pooling Project, spanning several decades. None had heart disease at baseline, and all experienced natural menopause.

Over time, researchers recorded hundreds of coronary events, including heart attacks and cardiovascular deaths. Even after adjusting for major risk factors such as smoking, obesity, hypertension, and diabetes, premature menopause remained strongly associated with increased lifetime heart disease risk—41% higher in Black women and 39% higher in white women.

Interestingly, while overall risk was higher, the age at which heart disease developed was similar across groups. This suggests that women with early menopause do not necessarily develop heart disease earlier but are more likely to experience it at some point in life.

The underlying mechanism is not fully understood, but declining estrogen levels are believed to play a central role. Estrogen helps protect blood vessels and regulate metabolism, so its early loss may accelerate cardiovascular risk. Experts also suggest premature menopause may reflect underlying inflammation or metabolic dysfunction.

These findings reinforce the importance of including reproductive history in cardiovascular risk assessment. Women with early menopause may benefit from earlier prevention strategies, including lifestyle changes and regular monitoring of heart health indicators.

Can Ashwagandha Gummies Improve Focus in Children? Experts Weigh In

A recent study published in Frontiers in Nutrition suggests that Ashwagandha root extract may safely support cognitive function and sleep in children aged 6–12 years. The eight-week randomized, placebo-controlled trial evaluated whether Ashwagandha root extract (ARE) could improve memory, attention, and overall well-being in children with mild attention or memory concerns.

The study included 85 healthy children from India and Australia, randomly assigned to receive either ARE gummies (150 mg twice daily) or a placebo. Cognitive performance was assessed using computer-based tasks, while parents completed standardized questionnaires to evaluate behavior and sleep patterns.

Results showed that children receiving ARE demonstrated significant improvements in processing speed, reaction time, verbal memory recall, and aspects of executive function compared to the placebo group. However, no major differences were observed in attention accuracy or episodic memory accuracy, indicating that the benefits were more related to efficiency rather than precision of cognitive performance.

Sleep quality also improved significantly in the ARE group, as measured by the Sleep Disturbance Scale for Children. Participants experienced fewer sleep disruptions, suggesting a positive effect on overall rest. Fatigue levels decreased in both groups, but the difference between ARE and placebo was not statistically significant.

Importantly, the supplement was well tolerated, with only mild and temporary side effects reported. No serious safety concerns were identified, supporting its short-term safety in children.

Despite promising findings, researchers emphasize that the study was exploratory, with a relatively small sample size and multiple endpoints. Therefore, results should be interpreted cautiously. Larger, long-term studies are needed to confirm whether Ashwagandha can be reliably used as a complementary approach to support cognitive development and sleep in children.

Study Links Belly Fat to Increased Heart Failure Risk Through Inflammation

New research presented at the American Heart Association EPI| Lifestyle Scientific Sessions 2026 highlights that fat stored around the waist—known as central obesity or visceral fat—may significantly increase the risk of Heart Failure, largely driven by inflammation. The findings suggest that where fat is stored may be more important than overall body weight.

The study found that higher waist circumference and waist-to-height ratio were more strongly associated with heart failure risk than body mass index (BMI). Notably, individuals with normal BMI but excess abdominal fat still faced elevated risk, indicating that BMI alone may underestimate cardiovascular danger.

Researchers followed nearly 2,000 adults for a median of 6.9 years, during which 112 participants developed heart failure. Blood tests revealed that higher levels of systemic inflammation—measured using markers such as C-reactive protein—were linked to increased risk. In fact, inflammation accounted for approximately 25% to 33% of the association between abdominal fat and heart failure.

These findings support growing evidence that American Heart Association has emphasized: chronic inflammation plays a key role in cardiovascular disease by damaging blood vessels, disrupting immune responses, and promoting tissue scarring in the heart.

Experts suggest that routine measurement of waist size could improve early detection of individuals at high risk, especially those who may appear metabolically healthy based on weight alone. Monitoring inflammation alongside central obesity may allow for earlier and more targeted prevention strategies.

The study underscores the importance of addressing visceral fat through lifestyle interventions such as diet, exercise, and weight management. Future research is needed to determine whether reducing inflammation can directly lower heart failure risk and how these findings apply across different types of heart failure.
