The Link Between Vitamin D and Cognitive Health

Let The Sunshine In: You might've heard that vitamin D is good for your bones, but researchers are increasingly interested in what the “sunshine vitamin” might be doing for your brain, too. A new study suggests that your levels during midlife could actually influence what's happening in your brain decades later.

The Study: Researchers followed nearly 800 adults for 16 years, measuring vitamin D levels once in midlife. Then, at the end of the study, researchers scanned participants' brains for buildup of certain proteins considered biological markers of Alzheimer's disease. People with higher vitamin D levels in their 30s and 40s showed lower tau protein levels years later.

The Takeaway: Midlife appears to be a window where keeping your vitamin D levels within a healthy range could have a real payoff for your brain decades later. Whether that means spending more time in the sunshine or looking into supplementation, it's worth bringing up at your next doctor's appointment if you haven't already.

Keep in Mind: The study only captured vitamin D levels at a single point in time rather than tracking them across the years, and a link between two things isn't the same as one causing the other.

Beyond Strength and Cardio: The Third Pillar of Longevity Fitness

You Should Know: The longevity fitness conversation has largely settled into two camps. On one side, you have the cardio-first crowd, focused on VO2 max and zone 2 training. And on the other, strength — grip strength and resistance training. Both are well-supported by research, and most experts agree you need some combination of the two.

Going Deeper: But there’s a third variable that doesn’t get nearly as much attention — force. More specifically, rate of force development. In layman’s terms, this is how quickly your muscles can produce force. Research suggests the ability to produce force rapidly declines with age faster than raw strength does, which is a big reason why falls become so dangerous later in life. Your legs may be strong enough, but they can’t fire fast enough. Training for force means incorporating explosive movements like box jumps, medicine ball throws, kettlebell swings, and jump squats.

Takeaway: Strength and cardio are both essential, but adding power-focused exercises into your workout may fill a gap that traditional training misses — one that is particularly important as you age.

Bottom Line: You’re not getting out of your current strength and cardio split (sorry). This research is just encouraging you to mix explosive movements into that routine.

An Audiologist's Top Daily Tips For Preventing Hearing Loss

“Come Again?”: Noise can be inescapable, from everyday sounds of traffic and restaurant chatter to the cacophony of a concert or sporting event. In between, we’re often pumping in more noise on purpose: podcasts during our commute, workout playlists at the gym, the white noise machine next to our bed. This might not feel too bad in the moment — but with enough exposure, this kind of noise can damage our hearing. Hearing loss by itself is bad enough, but it’s also associated with an increased risk of dementia. We’ve found some top tips for keeping your hearing as crystal-clear as possible.

The Benefits: Anything exceeding 85 decibels can damage your ears. A lawnmower clocks in at about 100 decibels. A concert? About 115. Some hearing loss is common as we age, but the link to dementia comes from losing brain stimulation from listening to and engaging in conversations.

How to Do It: Always wear hearing protection when you’re going to a concert or doing chores with noisy machinery (we like these). Keep the TV as low as you can. (You shouldn’t be able to hear it from another room.) Follow the “60-60 rule” with earbuds and headphones: no more than 60% volume for no longer than 60 minutes at a time.

This, Not That

Sweeten the Smart Way

NOT THAT

This: Cinnamon or Vanilla
Not That: Extra Sugar

Instead of adding more sugar to coffee, oatmeal, or yogurt, try spices like cinnamon or vanilla extract. They enhance sweetness without additional calories and bring subtle flavor complexity. It’s a small tweak that quietly cuts sugar intake.

Serves: 4-6 | Cook Time: 15 minutes

Spring is peak season for snap peas, and this dish makes the most of their natural sweetness and crunch. Tossed with fresh mint, creamy goat cheese, thinly sliced red onion, and toasted almonds, they’re brought together with a bright lemon–olive oil dressing. The result is a crisp salad that’s light and refreshing on its own, but can also be paired with grilled chicken or roasted salmon for a more filling spring meal.

HEALTHY HABIT

The “One Glass” Rule

Before opening a second beverage — coffee, soda, juice — drink one full glass of water. This small rule quietly boosts hydration throughout the day. Many people find it reduces unnecessary caffeine or sugar without feeling restrictive.
