EachNight Fact-Checking Standards and Processes

The EachNight writing team is devoted to creating articles that are not only entertaining and easy to understand but also as impartial, accurate, and well-sourced as possible. Whenever possible, we strive to have our articles fact-checked by our independent review board. We also do not tolerate plagiarism or ill intent from our contributors.

Here are the medical and factual guidelines that a EachNight article must adhere to:

  • We draw upon only reputable and respectable sources when researching our articles’ topics and endeavor to only link to highly authoritative sources. Such sources would include peer-reviewed medical and academic journals, medical and academic associations in good standing, and interviews with or blog posts from certified medical professionals.
  • We may link to news articles or peer-reviewed medical blog posts about studies when appropriate, but always attempt to connect directly to the studies these pages discuss.
  • Our scientific information, conclusions, and analysis are always supported by at least one reputable source.
  • We strive to make any potential conflicts of interest attached to any studies or sources clear to our readers. When applicable, we also try to include conflicting research or questions that may throw a study’s conclusion into doubt to clarify that scientific understandings often change and progress over time.
  • Our articles typically link to other articles and resources on our site. This is solely for easier navigation, and we do not promote our website as a medical resource. Try to speak with your physician if you have medical concerns.
  • Any necessary background information on a topic will be included when appropriate.
  • Our goal is for every one of our medical-related articles to be reviewed by our independent board of experts. Should they spot any medical or health-related misinformation or errors, we will strike it out from the final published article.

What’s a Certified Sleep Coach?

Our writers are sleep coaches certified by the Spencer Institute, which has been training coaches since 1992. Becoming a certified sleep coach means that our writers are well-versed in various sleep science matters, taking us beyond being just a group of mattress reviewers. The certification allows us an in-depth understanding of what we’re talking about when it comes to advising readers on better sleep habits.

About Us

Our simple goal is to provide the information you need to get better sleep each night. We provide a full-circle approach to sleep and wellness.
