The HLTH Journal·The Science
Our medical review process
What we check before health content goes live on this site, who checks it, and what they are asked to push back on.

MEDICAL ADVISORY BOARD
Two named doctors. Every health claim checked.

Health content on the internet has a trust problem. Most of it is written to rank on Google, not to be accurate. Claims get exaggerated, studies get misrepresented, and the reader, who is just trying to understand their body better, ends up more confused than when they started.
Why we have a medical review process
We decided early on that we were not going to do that.
Every piece of content on this site that touches heart health, cardiovascular monitoring, HRV, blood pressure, sleep or recovery is read by a named, credentialed medical professional before we publish it. Their job is not to approve our marketing. Their job is to tell us when we are wrong.
If a claim cannot be supported by evidence, it does not go in. If a finding is preliminary, we say so. If something requires a doctor and not a wearable, we say that too.
Who reviews our content
Our advisory board is two practising doctors. Both work in the areas the band measures, and each is named on the articles they have read. Their own words on why continuous measurement matters are below.
Dr. Alexis Nelson, MBBS
General Practice · Resident Doctor, NHS
“Blood pressure and oxygen levels are markers we already track in practice. What wearable technology adds is continuity: the ability to observe how those numbers shift across daily life, not just in a single appointment. For patients who want to stay informed between visits, that kind of ongoing visibility can be genuinely valuable.”
Dr. Alexander Acosta, MD
Real-Time Health Monitoring
“Real-time health data changes the relationship between patients and their own bodies. The HLTH Band tracks and monitors relevant metrics (blood pressure, heart rate, SpO2) in the hands of people who want to stay ahead of their health, not just respond to it.”
How the review process works
When a new article is written, it goes to the relevant medical advisor before it is published anywhere. The reviewer checks three things. Once an article passes review, the advisor's name appears as a byline at the top of that piece.
01
Factual accuracy
Are the claims supported by the studies cited? Are the numbers correct? Is anything stated as established fact that is actually still debated in the literature?
02
Appropriate scope
Does the content stay within what a consumer wearable can and cannot do? The HLTH Band is not a medical device and is not a substitute for clinical care. Our advisors make sure that line is never blurred.
03
Harm prevention
Could any piece of advice cause someone to delay seeking medical attention, misinterpret a reading, or make a health decision they should be making with a doctor? If the answer is yes, the content is revised before it goes live.
A note on independence
Our medical advisors are paid for their time. We think that is the honest way to do it, because unpaid advisory roles create conflicts of their own.
What they are not paid to do is agree with us. Their role is specifically to push back when we get something wrong. If an advisor tells us a claim is not supported by the evidence, we change the claim, not the advisor.
