A real step-count mismatch between Apple Watch and iPhone almost never means double counting. How to check Health's data source priority, catch a rogue third-party app, and fix a genuine gap.
A 2023 meta-analysis of over 508,000 adults and a 2022 NIH All of Us study both link daily steps to lower type 2 diabetes risk. The real numbers on volume and pace, and how to actually hit them.
WHO and CDC guidelines call for 150-300 minutes of moderate-intensity activity a week. Here's the pace that actually counts as moderate walking, backed by real cadence research, and how many steps that adds up to.
A 348,000-person UK Biobank study links walking pace to bone density and fracture risk. What that study and two others found about pace, volume, and steps for bone health.
How much water to drink for a 5,000, 10,000, or 15,000-step walk, based on real sports-medicine hydration guidelines - plus how to tell if you're drinking too little, or too much.
Three real studies measured cortisol before and after a walk - not just claimed it helps. What actually moved the number, how long it took, and why where you walk mattered as much as how far.
Your watch counts steps from arm swing - and pushing a stroller or cart kills it. What a 2022 study found about the undercount, why your iPhone is different, and how to actually get credit for the walk.
Your walking route isn't broken - GPS on foot has real, physical limits. Why routes zigzag, why distance reads too short or long, and what you can actually do about it before your next walk.
The MET formula every steps-to-calories calculator uses, why 10,000 steps burns a range and not a fixed number, and why your phone's calorie count won't match a generic calculator's.
