Evidence & Sources
Useful guidance deserves visible evidence.
We prefer primary public-health guidance and high-level research reviews, preserve population and timeframe context, and describe uncertainty instead of turning early findings into promises.
Source first
Government health agencies, systematic reviews, meta-analyses, and peer-reviewed studies take priority over trend-driven summaries.
Context intact
Numbers keep their population, date, comparison, and limitations. A research association is not rewritten as causation.
Education, not care
Content supports informed everyday choices. It does not diagnose, prescribe, treat, cure, or replace individual medical care.
Evidence at a glance
Real recommendations, shown with their limits.

A snapshot of the landscape.
Three published survey estimates that describe how common these everyday patterns are among U.S. adults.
Slept less than 7 hours on average
30.5%
U.S. adults, 2024
Estimated share of adults whose average sleep duration was under 7 hours, from national survey data.
CDC/NCHS Data Brief 559 — Short Sleep Duration and Sleep Difficulties Among Adults: United States, 2024 (published April 2026)Met both aerobic and muscle-strengthening guidelines
24.2%
U.S. adults aged 18+, 2020
Estimated share of adults meeting BOTH federal aerobic and muscle-strengthening recommendations.
CDC/NCHS Data Brief 443Reported meditation use
17.3%
U.S. adults, 2022 (7.5% in 2002)
Reported use of meditation, up from 7.5% in 2002. Use is not a measure of effectiveness.

These figures come from different surveys, populations, and timeframes. They are shown for context only — they are not directly comparable measurements, not a trend, and not evidence for the Supreme Wellness Method. Nothing here describes a cause, an effect, or an expected result for any individual.
Our review standard
What readers can expect
- Dates that matter. Articles show published and updated dates so readers can judge currency.
- Sources at the claim. Numeric and contested claims link to their source in the article, with a complete source list below.
- Clear limits. Mixed evidence, study quality, age group, and wide individual variation stay visible.
- Practical translation. Research informs low-risk educational options, never a claim that the Supreme Wellness Method itself is clinically proven.
- Ongoing correction. Substantive updates change the updated date; errors are corrected rather than quietly preserved.
