Most insomnia advice defaults to a supplement bottle — melatonin, magnesium, valerian — because a pill is the easiest thing to market and the easiest thing to try. A quieter but better-evidenced option has been building a real research base for years: structured, app-delivered cognitive behavioral therapy for insomnia, known as CBT-I. A 2026 randomized […]
Three days into a genuine calorie deficit, the scale hasn’t moved, the mirror looks the same, and it’s tempting to conclude the plan isn’t working. It usually is — the body just doesn’t report fat loss in real time, and the reasons why are physiological, not a sign of failure. What Actually Happens in the […]
Continuous glucose monitors used to be strictly medical devices for people with diabetes. Now they’re marketed directly to healthy people as a window into metabolism — a way to see, in real time, how a bagel or a stressful meeting moves your blood sugar. The pitch is compelling. The evidence behind it, for people without […]
The FDA has been trying to ban formaldehyde in keratin and hair-smoothing treatments since warnings first surfaced between 2010 and 2016. As of early 2026, it still hasn’t finalized that rule — missing its own proposed deadline again. If you’ve booked (or are considering) a keratin treatment, here’s what the actual health data says, and […]
Most hair-loss content online treats “hair loss” as one condition with one drug pathway — minoxidil, finasteride, maybe a laser cap. That framing works for pattern (androgenetic) hair loss, but it’s the wrong toolkit entirely for alopecia areata, an autoimmune condition where the immune system attacks hair follicles directly. 2026 has been an unusually active […]
Peptide serums have quietly taken over the space on skincare shelves that retinol alternatives used to occupy — marketed as the gentle, science-sounding way to firm skin without irritation. The word “peptide” on a label does real scientific work: peptides are short chains of amino acids that can signal skin cells to behave differently. What […]
Walk down the moisturizer aisle with genuinely dry skin and the choice isn’t really between brands — it’s between a $9 tub and a $95 jar that often share more ingredients than either label wants to admit. Dermatologists have been saying for years that price is a weak predictor of how well a moisturizer treats […]
“Cortisol face” has become a shorthand explanation for almost any facial puffiness that shows up online — a swollen morning selfie, under-eye bags after a bad night, a rounder face than usual, all attributed to a stress hormone supposedly wrecking your appearance in real time. The actual endocrinology tells a much narrower, much less dramatic […]
BMI has been the default number doctors and apps use to sort people into weight categories for decades, and it has also been criticized for just as long for missing something obvious: two people with an identical BMI can carry their weight in completely different ways, with very different health implications. A large new study […]
Step-count calculators and daily targets are everywhere — on phones, watches, and apps that all promise the same thing: hit this number and the pounds follow. The step-tracking part is accurate; the weight-loss math behind it is where the promise gets ahead of the actual research. Where the 10,000-Step Number Actually Came From The 10,000-step […]
