A large observational study (2025) from Australia’s Monash University, spanning a decade and involving over 10,000 people over 70, found that people who listened to music most days slashed their risk of developing dementia by 39% compared with those who did not. The regular music-listeners also had a decreased risk of experiencing general cognitive decline and performed consistently better on memory tasks and cognitive function…
Obesity has boomed in industrialized nations over the last century, and a common explanation is that we’ve become more sedentary, so we burn fewer calories. But a major new study (2025) finds that this is not the case. Global researchers compared the daily total calorie burn for people from 34 different countries and cultures around the world––from hunter-gatherers and farming populations with low obesity rates,…
A large, long-term study from the Mayo Clinic, tracking 2,750 adults (aged 50 and over) for an average of five and a half years, found that chronic insomnia leads to changes in the brain that result in a much faster decline in memory and thinking. Chronic insomniacs were 40% more likely to develop cognitive impairment or dementia over the study period than people that got good…
A 2025 study from Vanderbilt University Medical Center (on 85,000 predominantly Black and low-income participants) found that just 15 minutes of brisk walking daily were linked with a nearly 20% reduction in mortality. The positive effects of walking have been endlessly documented, but this research revealed that walking quickly delivers health benefits in a very short timeframe. Slow walking for more than three hours daily was…
Nightmares Linked to Rapid Biological Aging and Early Death A 2025 study from Imperial College London, analyzing 183,000 adults and 2,400 children, found that those who had bad dreams once a week or more had shorter telomeres, associated with faster cellular aging. They also found that those who experienced regular nightmares were three times more likely to die before the age of 70 compared with those who did not––concluding…
Landmark Study Shows Exercise Is “Better Than Drugs” in Stopping Cancer Returning A world-first randomized controlled trial (2025) with patients from the US, UK, Australia, France, Canada and Israel has found that a structured exercise regime after cancer treatment (with a personal coach and movement equivalent to three to four walks a week of between 45 and 60 minutes) can dramatically reduce the risk of…
