Dr. Samantha Youmeen (2:20)
It's always great to start off the year with good news and what's more positive than giving animals a safe and loving home? In this episode I'll speak to wildlife conservationist Forrest Galanti about his latest project documenting the inner workings of one of the biggest animal sanctuaries and rehabilitation centers on the planet. The series is called Sanctuary stories, and it's streaming on HBO Max and Discovery. Then we're going to keep the good vibes rolling by getting into a new study that explores how helping others, even in the smallest ways, improves cognitive function. But before that, we'll talk about a recent study that looks into what actually makes an elite performer, be it an athlete, academic or musician. So whether it's pursuing excellence, being kind, or helping animals, we've got the scientific evidence to back up being good. Welcome to Curiosity Weekly from Discovery. I'm your host, Dr. Samantha Youmeen. Let's do it. Researchers found a powerful way to help protect your brain health. Help someone else. The team found that regularly helping others outside your home significantly slows cognitive decline as we age. The researchers are from the University of Texas at Austin and the University of Massachusetts, Boston. They used data from the National Health and Retirement Study, which goes back to 1998, so they could follow people over two decades. They analyzed data from over 31,000 adults in the US over the age of 51. They found that people who spent about two to four hours per week helping others experienced a 15 to 20% slower rate of cognitive decline. They published the study in October 2025. That's a meaningful difference in how quickly things like memory and thinking skills change over time. And helping here doesn't mean anything extreme. In fact, it's one of the few studies to look at both formal volunteering, like organized community work, and and informal helping that includes things like driving someone to a medical appointment, helping with childcare, doing yard work for a neighbor, or even preparing someone's taxes. Informally helping out is often assumed to have fewer health benefits because it doesn't come with the same social recognition or structure as like formal volunteering. But in this study, that assumption didn't hold up. Both forms of helping were beneficial for cognitive health. Those who stayed engaged in either way. Helping others year after year built up accumulated cognitive benefits. And the opposite was true, too. People who withdrew from helping roles had worse cognitive function over time. In other words, this isn't a one and done type thing. The benefits add up, but they can also be lost. And factors like wealth, education, and physical and mental health didn't seem to change the result. This makes it less likely that the results were simply explained by people who were already healthier or had other privileges related to brain health. Now, of course, it'd be great if we could do a ton of volunteering every day. That's not always practical, but there still seems to be value in moderate, regular helping few hours a week and keeping people involved in helping roles even later in life or after some cognitive decline may be protective. In an aging society with growing concerns about loneliness, isolation and cognitive decline, this is a promising low risk approach that may be good for us and those around us.
