# WellnessInsider > Evidence-graded reporting on longevity, sleep, nutrition, fitness, recovery, and metabolic health. The extended index, with per-article summaries, evidence-grade distributions and bylines, is at https://www.mywellnessinsider.com/llms-full.txt. ## Key Facts - Publisher: WellnessInsider. - Editorial model: every health claim is graded A-D against primary sources (peer-reviewed studies, clinical guidance, regulatory statements) before an article can publish. The grading rubric is public. - Bylines: every article carries a byline, an evidence grade, and a visible last-updated date. Staff-desk work is published under the WellnessInsider Editorial Team byline. - Medical review: a named-clinician review layer is implemented and is displayed on any article that carries a sign-off, with the reviewer's credentials and review date. No article in the current corpus has been through clinical review, and none claims to have been. - Commercial disclosure: any promoted brand mention carries a visible FTC-style disclosure on the page, and the publishing gate rejects a promoted mention that lacks one. Editorial coverage is decided on merit and is never sold. - Corrections: substantive factual corrections are logged with dates and change summaries rather than edited away silently. - Topics covered: Fitness, Longevity, Metabolic Health, Nutrition, Recovery, Sleep. ## Editorial Standards - [About](https://www.mywellnessinsider.com/about): who publishes this site, the ownership structure, and the editorial mission. - [Methodology](https://www.mywellnessinsider.com/methodology): the A-D evidence-grading rubric applied to every health claim. - [Editorial Standards](https://www.mywellnessinsider.com/editorial-standards): sourcing policy, review process, and the rules that govern every article. - [Corrections](https://www.mywellnessinsider.com/corrections): the corrections log, with dates and change summaries. - [Disclosure Policy](https://www.mywellnessinsider.com/disclosure-policy): how commercial relationships are disclosed and what they do not buy. - [Brand Review Process](https://www.mywellnessinsider.com/brands/review-process): the public rubric every brand is scored against. - [Brands We Trust](https://www.mywellnessinsider.com/brands): the scored brand directory. ## Topics - [Fitness](https://www.mywellnessinsider.com/fitness): Training dose, cardiovascular and strength adaptation, and what the research supports. - [Longevity](https://www.mywellnessinsider.com/longevity): Healthspan, biological ageing, and the interventions with evidence behind them. - [Metabolic Health](https://www.mywellnessinsider.com/metabolic-health): Glucose regulation, body composition, and the metabolic markers worth tracking. - [Nutrition](https://www.mywellnessinsider.com/nutrition): Protein, micronutrients, supplements, and how to read the evidence behind a label. - [Recovery](https://www.mywellnessinsider.com/recovery): Heat, cold, and rest protocols, and the difference between recovery science and ritual. - [Sleep](https://www.mywellnessinsider.com/sleep): Sleep architecture, circadian timing, and what actually improves sleep quality. ## Published Articles - [Zone 2 Cardio: How Much a Non-Athlete Actually Needs](https://www.mywellnessinsider.com/fitness/zone-2-cardio-how-much): Low-intensity aerobic training builds mitochondrial and cardiorespiratory capacity, but the weekly dose that matters is smaller, and the zone boundaries far looser, than the charts suggest. - [Sleep Architecture: What Happens Across a Night](https://www.mywellnessinsider.com/sleep/sleep-architecture-explained): A night of sleep runs four to six NREM-REM cycles with deep sleep front-loaded and REM back-loaded, and consumer trackers misjudge both. - [Sauna and Longevity: What 20 Years of Finnish Data Show](https://www.mywellnessinsider.com/recovery/sauna-longevity-evidence): Frequent Finnish sauna use tracks with sharply lower cardiovascular and all-cause mortality across two decades of cohort data, and no randomized trial has yet confirmed it. - [Protein Requirements After 40: What the Evidence Says](https://www.mywellnessinsider.com/nutrition/protein-requirements-after-40): The protein RDA of 0.8 g/kg was built to prevent deficiency in the average adult, and two expert consensus groups put the figure for healthy older adults 25 to 50 percent higher. - [Morning Light: The Highest-Evidence Circadian Habit](https://www.mywellnessinsider.com/sleep/morning-light-circadian-habit): Light after waking advances the body clock through melanopsin-carrying retinal cells, and outdoor illuminance beats indoor lighting by a factor of eight or more. - [How to Read a Supplement Label: What the Law Requires](https://www.mywellnessinsider.com/nutrition/how-to-read-a-supplement-label): US law does not require FDA approval before a supplement is sold, which shifts most of the verification burden onto the label itself and onto the person reading it. - [Grip Strength and Healthspan: What the Cohort Data Shows](https://www.mywellnessinsider.com/longevity/grip-strength-and-healthspan): Grip strength, gait speed, sit-to-stand and VO2max predict mortality more strongly than most consumer health metrics, and prediction is not the same as cause. - [Continuous Glucose Monitors Without Diabetes: The Evidence](https://www.mywellnessinsider.com/metabolic-health/continuous-glucose-monitors-without-diabetes): Over-the-counter sensors turned continuous glucose monitoring into a consumer product in 2024. What the readings measure, how far they sit from blood glucose, and what normal variability looks like. - [Cold Plunge Science: Real Recovery, Real Training Costs](https://www.mywellnessinsider.com/recovery/cold-plunge-recovery-science): Cold-water immersion reliably lowers muscle soreness, and used straight after lifting it measurably reduces the muscle growth that resistance training is meant to produce. - [Blue Zones Reassessed: What Holds Up and What Does Not](https://www.mywellnessinsider.com/longevity/blue-zones-what-holds-up): The longevity-hotspot idea rests on birth records that in many regions were never reliable, and the lifestyle findings that survive that problem survive on other evidence entirely. ## Contact - [Report a correction](https://www.mywellnessinsider.com/corrections): how to flag a factual error and what happens after you do. - [Editorial contact](https://www.mywellnessinsider.com/about): how to reach the editorial team.
