Better questions. Better sources.
A practical directory of public-health agencies, consumer-protection materials, cybersecurity guidance and published research that can help you check claims for yourself.
We aim to explain both what a source can support and what it cannot. A link to a respected institution is not proof that every recommendation on our site is correct.
11 selected sources · Checked 16 October 2026 · General education, not individual professional advice
Use evidence as a starting point, not a shortcut.
A source may describe an average, a public-health target or a finding from a particular study population. Your circumstances can be different. When reading a claim, ask what was measured, who was studied and whether the research supports the exact conclusion being made.
We have selected a small number of useful starting points, not compiled a systematic review of every topic. Please check the source’s own publication dates, definitions and updates.
Understand the basics before changing a habit.
These public-health sources summarize general recommendations. They do not assess an individual’s medical needs, disability or living situation.
CDC / Physical activity
Practical ways adults can add activity, with the recommended weekly targets and an emphasis on starting at a manageable level.
Keep in mind: U.S. population guidance, not a personal exercise prescription.
CDC / Sleep
Age-based sleep needs, sleep quality and signs that deserve a conversation with a healthcare professional.
Keep in mind: Sleep quantity alone does not diagnose insomnia or sleep apnea.
WHO / Healthy diet
Balanced dietary principles and the role of nutritional adequacy, moderation and diversity.
Keep in mind: Dietary needs vary by life stage, health conditions and available food.
Make decisions with clearer numbers and risks.
Financial resources can help you organize choices, but tax, debt and investment rules depend on where you live and your circumstances.
CFPB / Financial well-being
A framework for day-to-day money control, absorbing shocks, meeting goals and having freedom of choice.
Keep in mind: The measures and supporting research come from a U.S. institution.
CFPB / Your Money, Your Goals
Free bill calendars, spending trackers, cash-flow tools and decision worksheets.
Keep in mind: Some templates reference U.S. laws, institutions and terminology.
FTC / Cryptocurrency and scams
Consumer warnings about common crypto-fraud tactics, misleading profit claims and payment risks.
Keep in mind: Fraud reporting, financial safeguards and legal remedies vary by country.
Use research to make practice more effective.
Research reviews are useful starting points, but one study cannot predict an individual student’s results in every subject.
Dunlosky and colleagues / Learning techniques
A published review comparing commonly used study methods, including practice testing and distributed practice.
Keep in mind: A research review, not a guarantee that any technique works equally for everyone.
Karpicke / Retrieval practice review
Research overview explaining why retrieving information from memory can support later retention.
Keep in mind: Effects depend on task design, feedback and what is being learned.
Improve security without relying on guesswork.
Security steps evolve as authentication technologies and threats change. Review account-specific instructions before changing access settings.
NIST / Multi-factor authentication
An accessible explanation of MFA and why an additional authentication factor can help protect accounts.
Keep in mind: Recommendations should be matched to each service and its recovery options.
Choose actions with practical everyday value.
Community and environmental outcomes depend on local conditions, available services and what people can realistically do.
EPA / Preventing wasted food at home
Guidance on meal planning, storing food and using what is already available to reduce waste.
Keep in mind: Local waste systems and food handling guidance may differ.
U.S. Surgeon General / Social connection
A public-health overview of social connection and its relationship to health and community.
Keep in mind: Population findings cannot predict the quality or outcome of one relationship.
Four questions worth asking.
Look for identifiable authors, institutions, publication dates, funding and any potential conflicts of interest.
Differentiate experimental research, observational studies, expert guidance, consumer alerts and personal stories.
Consider the country, age group, study population, context and whether the findings are consistent with other evidence.
Be suspicious when someone turns a conditional finding into a promise, removes meaningful limitations or uses a referral link as proof.
Check one claim, step by step.
Choose a statement from one of our guides and see whether a source truly supports it. You don’t need specialized software or advanced research training to begin.
- Find the exact claim. Copy the sentence or number you want to check, including any age group or timeframe.
- Open the original reference. Look for the relevant passage rather than relying on a headline or summary.
- Read its date and scope. Determine whether the material describes a country, study group or professional guideline.
- Compare carefully. Ask whether the source supports the entire claim or only a narrower part of it.
- Record uncertainty. If the conclusion seems exaggerated or outdated, contact us with the article and source links.
Example: The CDC sleep guidance describes population recommendations and advises medical follow-up for persistent sleep difficulties. That does not mean a fixed bedtime alone will solve every individual’s sleep problem.
Questions about using these sources
Does a source linked here prove every claim in a Better Lifestyle article?
No. A source can support a specific fact while not supporting broader conclusions. We invite readers to check whether the linked document genuinely matches the claim and to report discrepancies.
Why are many sources from the United States?
Several well-documented public education resources are published by U.S. agencies. They can help explain principles, but laws, consumer protections, clinical guidance and services elsewhere can differ. Please consult local authorities for jurisdiction-specific decisions.
How should I use a scientific study?
Read its abstract, methods, population and limitations before assuming its result applies to your situation. Systematic reviews and professional guidance may help contextualize individual studies. A study is not personalized advice.
What if a reference is broken or outdated?
Send us the page URL and the broken reference using our Contact page. We aim to review substantive corrections; we cannot promise a particular response time or guarantee that external sites remain available.
For a quick evaluation, check author, publication date, methodology and whether the claim matches what the source actually reports. Explore practical guides or read our editorial standards.
