Key Highlights Understanding how our body’s clock affects our brain is an exciting new frontier in health. The term chronotype simply means your natural sleep-wake preference – for example, being a “morning lark” or a “night owl” (Sleep Foundation, 2024). We all have a built-in circadian rhythm that makes us feel more alert at certain…
Key Highlights What Is Passive Heat Therapy? Passive heat therapy simply means heating your body from the outside (without exercise). Think hot tubs, steam baths, and saunas. It’s a time-honored practice in many cultures: from Japanese onsen and Turkish hammams to Finnish saunas. In scientific terms, passive heat therapy exposes you to high temperatures (often…
Key Takeaways Chronological Age vs. Biological Age Everyone has a chronological age (the number of birthdays you’ve had) and a biological age (how “old” your body and cells really are). While you can’t change your birthdate, you can influence your biological age. In fact, experts estimate genetics only account for ~15–25% of aging, meaning lifestyle…
Key Highlights Imagine if some benefits of your daily jog could be captured in a single nutrient. It sounds like science fiction, but researchers have uncovered exactly that: betaine, a tiny molecule in your body, seems to act like a miniature version of exercise, protecting cells from aging. This discovery doesn’t mean you can skip…
Key Highlights It’s time to unpack a brand-new study that put two of the world’s healthiest diets—Vegan and Mediterranean—into a scientific cage match (Parmenter et al., 2025). The goal? To see which one puts less acid-related stress on the body. The results are intriguing and, more importantly, provide a new tool for the personal health…
Key Highlights Aging is inevitable, but how we age isn’t set in stone. Scientists now show that diet plays a huge role in not just living longer, but living better: staying active, thinking clearly, and avoiding chronic diseases like heart disease, diabetes or dementia as we get older. Let’s break down the science into simple…
Key Highlights Eating a wider variety of plant foods (that supply different flavonoids) was linked to significantly lower risk of death and chronic diseases. It’s not just the quantity of flavonoids you eat but how many types – diversity + quantity was the winning combo. Practically, this means including several different flavonoid-rich foods each day…
Key Highlights What is the Gut Microbiome? Your gut microbiome is the bustling community of trillions of bacteria living in your digestive tract. Think of it as a rainforest in your belly, where a wide variety of plant and animal life keeps the ecosystem balanced. A diverse microbiome generally means a healthier gut – with…
Key Highlights What Is the Sitting-Rising Test? The Sitting-Rising Test (SRT) is a simple functional fitness challenge. You stand normally, then lower yourself to the floor and stand back up, using as little support as possible. You start with 10 points. Each time you put a hand, knee or any part of your body on…
Key Highlights What is an Epigenetic Clock? Think of an epigenetic clock like a little odometer built into your DNA. As we age, chemical tags (DNA methylation) accumulate at certain spots on our genes. Scientists have trained algorithms (clocks) to read those tags and predict biological age, which may differ from calendar age. Unlike birth…
