Top 16 Must-Read Longevity Articles for 2025 – And Why They Matter
If there’s one thing I’ve learned immersed in the worlds of longevity and integrative health, it’s that science never stands still (and thank heavens for that!). Just about every day, fascinating new ideas and insights emerge to dig into. Some confirm what we’ve long suspected, while others may challenge our assumptions, and still others may give rise to entirely new ways of thinking about how we age and how we thrive.
These days, I’m typically sifting through countless new studies and newsworthy stories from across the longevity spectrum. And every so often, an article will stop me in my tracks. It may offer a radically new perspective, or connect the longevity dots in an unexpected way, or reveal something so profound that I can’t help but think, everyone should know this!
As 2025 draws to a close, I want to take a moment to share what I consider to be some of the most fascinating and thought-provoking writing about longevity published in the past twelve months. Think of this sample of must-read articles as a reminder that your healthspan – those vibrant, fully functional years – is far less about luck and genetics than you may have thought, and a lot more about personal agency, that is taking control. The idea that your lifestyle choices can help reprogram your biology is both humbling and inspiring, and one we can all take to heart as we roll into a new year.
Longevity science is a living, evolving story that we’re all part of. My hope is that this collection will spark your curiosity, inspire you to continue on a path of steady health improvement, and light your way toward a longer and more vibrant life.
