Vitamin C Might Do More Than Boost Your Immune System

Hi-C: You probably think of vitamin C as an immunity booster that you reach for as a supplement when you feel a cold coming on. However, new research published in PLOS One suggests its impact might extend to a less expected place. Like deep inside your brain, for instance.

The Study: Researchers scanned the brains of and tested blood samples from over 2,000 adults in Japan aged 65 or older. After accounting for differences in age, education, and activity levels, they found that lower vitamin C levels were associated with reduced gray matter and weaker connections within the brain’s default mode network, a system linked to memory and attention.

The Takeaway: The vitamin C levels were linked to changes in brain structure, not just scores on a memory test, so this research adds to the case that everyday diet could affect how your brain ages.

Keep in Mind: This is an observational study and doesn’t prove vitamin C directly protects the brain. More research is needed before this changes anyone’s supplement routine.

For a long time, “recovery” sounded like something only athletes took seriously. Now it’s becoming part of everyday wellness, especially for people who walk, work out, sit too long, travel, or just want to feel a little less stiff the next morning.

That’s where Hyperice fits in. Its lineup includes Hypervolt massage guns for muscle tension, Normatec dynamic air compression boots for tired legs, and Venom heat-and-vibration wraps for targeted comfort.
It’s the kind of recovery gear once found in training rooms, now built for home routines.

Can Better Breathing Lead to Better Decisions?

Take a Breath: We’re supposed to listen to our gut when faced with a tricky decision, but that advice perhaps should be tweaked to “listen to our breath.” Breathwork can help us calm down, manage stress, and regulate our nervous systems. Research shows that certain breathwork patterns may also help us make better decisions.

How to Do It: Researchers presented participants with a risky financial decision: a 50/50 gamble in which they could either win or lose money. How they breathed affected the decision they made, with blood flow to their brains measured by a functional MRI. Those who did a slow long-exhalation breathing pattern — a two-second inhale followed by an eight-second exhale, repeated several times — found the potential rewards were amplified.

Why It Works: Long exhalation slows the heart rate and stimulates the vagus nerve to activate the calming parasympathetic “rest and digest” nervous system. It helps the brain become attuned to the opportunities of an action instead of its potential downsides. Repeating this practice for several minutes before making a big decision, taking a step that makes you nervous, or having a difficult conversation can help you focus on what could go right instead of what could go wrong.

Is Running on a Treadmill Just as Good as Running Outside?

You Should Know: Runners tend to have very strong opinions about the treadmill versus outdoor running debate. But the real question isn’t which is “better” — it’s what you want from your workout. When effort is comparable, research suggests both improve cardiovascular fitness, endurance, and overall health. They offer different experiences, each with its own advantages and drawbacks. But depending on your goals — and what your body needs on a given day — one may be a better fit than the other.

Going Deeper: Outdoor running exposes you to varied terrain, wind resistance, and elevation, which makes it best for preparing you for the conditions you’ll experience in an outdoor race. It also comes with a mental health bonus: Studies have found that exercising in nature can improve mood, reduce stress, and leave people feeling more energized than indoor workouts. Running indoors makes it easier to control pace and incline, which is a bonus if you’re doing speed or tempo workouts. They’re also safer, since you’re not exposed to traffic, weather elements, or wildlife. Treadmills may also reduce joint impact compared to running on natural surfaces.

Takeaway: Even though treadmills remove some of the challenging variables of outdoor running, they’re still valuable training tools and make running accessible to people who can’t or don’t want to run outside.

Bottom Line: Outdoor running better prepares you for real-world conditions, while treadmill running makes quality training easier to fit into everyday life.

Serves: 4 | Cook Time: 25 minutes

People are eating more dates than ever, often as a natural way to add sweetness to meals or as a stand-alone snack — but this recipe gives the trending fruit a savory twist.

Start by softening the dates with lemon juice and orange blossom, adding bright acidity and floral notes. They’re then tossed with crisp lettuce, cucumbers, radishes, and mint, and coated in a creamy dressing made with tahini, yogurt, and a medley of spicy elements like gochujang and harissa. At the end, a sprinkle of sesame seeds finishes the dish with a satisfying crunch, bringing together the perfect balance of natural sweetness, crisp veggies, and a creamy, subtly spicy dressing.

HEALTHY HABIT

Keep a Snack You Actually Want Around

The best healthy snack is the one you’ll actually eat. Stock one option that’s easy, filling, and satisfying — nuts, fruit, jerky, hummus, string cheese, yogurt, or a protein bar you like. Planning ahead beats negotiating with yourself at 3 p.m.
