What's new in feeling better and living longer. 5-minute read.
Good morning. Today: what 12 years of records showed about modern hormone therapy and the heart, what FDA adverse-event reports showed about energy drinks, and how much sleep Sunday's clock change actually added.
01 ยท HRT ยท HEART HEALTH
Modern hormone therapy wasn't tied to more heart disease
In an Israeli study of 52,330 women aged 45 to 59 followed an average of 12 years, those who started menopause hormone therapy had similar numbers of heart attacks, strokes, blood clots and early deaths as women who didn't.
Why it matters: Heart risk has long been one of the biggest worries about hormone therapy, and this study looked at today's formulations, including patches and gels.
The details: The women, drawn from Clalit Health Services records, had no prior heart disease, clots or cancer. About half started oral or transdermal hormone therapy; the rest saw a gynecologist but didn't start it. Heart attack, stroke or related heart disease occurred in 2,311 women in the hormone therapy group and 2,383 in the comparison group. Blood clots: 174 vs. 175. Deaths before age 80: 659 vs. 653. Results were similar across pills, patches and gels.
Yes, but: It's observational and couldn't account for differences like exercise or symptom severity. It's a preliminary abstract, not yet peer reviewed, to be presented at AHA Scientific Sessions Nov. 6 to 9. Lead researcher Ronen Arbel said current options "do not appear to raise the risk of heart attack, stroke, clots or early death, even after long-term use."
02 ยท CAFFEINE ยท HEART HEALTH
Energy drink reports were tied to cardiac arrest in young adults
In 28,345 reports to an FDA adverse-event database from 2017 to 2025, cardiac arrest was reported about 11 times more often with caffeine and stimulant products, such as energy drinks and pre-workout supplements, than with other foods and supplements.
Why it matters: Energy drink sales topped $20 billion in 2024, and some pre-workout products carry more than 12 times the caffeine per fluid ounce of brewed coffee, per the American Heart Association.
The details: 854 of the reports involved caffeine or stimulant products. Those reports were also tied to heart attack (about 4.5 times as likely), ventricular arrhythmias or palpitations (about 4 times) and fainting (about 2 times). About 45% of the heart-related reports tied to these products came from adults 18 to 34, and patterns were similar in women and men. The University of Virginia abstract will be presented at AHA Scientific Sessions, Nov. 6 to 9.
Yes, but: Reports are voluntary, so the analysis shows associations only and can't count people who used the products without problems. The findings are preliminary and not yet peer reviewed. "This study raises concerns that products with very high amounts of caffeine may be harmful to the cardiovascular system," said UCSF cardiologist Gregory Marcus, who wasn't involved.
03 ยท SLEEP
The fall clock change added about 33 minutes of sleep
Among 11,780 UK Biobank participants aged 43 to 78 who wore wrist trackers, sleep on the Sunday the clocks went back was 33 minutes longer than the Sunday before.
Why it matters: U.S. clocks fell back on Nov. 1, and the study measured what the "extra hour" looks like in real sleep data.
The details: Sleep on the fall clock-change Sunday was also 38 minutes longer than the Sunday after, with some extra catch-up sleep on the following weekdays. In spring, sleep was about 61 to 65 minutes shorter on the Sunday clocks moved forward. The data covered clock changes from 2013 to 2015. Published in the Journal of Sleep Research.
Yes, but: The 33 minutes is a population average, and the study measured sleep duration only, not quality or alertness. Participants were in the UK, so results may not carry over to U.S. adults. Funding wasn't reported in the coverage.

The Glutathione Masterclass | A Complete Research Guide (2026)
Glutathione is the most boring compound Hunter uses. It's also one he'd put in his top five peptides.
Your cells make it every day. It's your main internal antioxidant, the buffer that soaks up the damaging byproducts of making energy. Levels drop with age, alcohol, illness and hard training. When that tank runs low, a lot of other therapies stop working as well.
In this masterclass Hunter breaks it down in plain English. Then he covers who actually benefits and who can probably skip it. He walks through every delivery route and what the human data shows for each.
