How we work
We read the research so you don't have to
For each guide we publish, we start with the peer-reviewed literature and only then look at products. We aggregate verified owner reviews, independent third-party testing where it exists, manufacturer specifications, and expert analysis. We weight peer-reviewed studies and lab tests above brand marketing and influencer endorsements. We define the evaluation criteria up front so you can disagree with our weights if you want.
We do not accept payment for reviews. Brands cannot buy placement. We do not use AI to write our guides, and the one you are reading was written by a person who actually evaluated the evidence, not by a model that summarized it.
Full breakdown of the research process, the four-tier evidence grading framework, and what we will not do is on the methodology page.

Sleep optimization: what the evidence says to do, in order
The AASM recommends against sleep hygiene as a stand-alone treatment, so what actually works is a sequence: sleep window first, then light, caffeine, alcohol and temperature. 14 peer-reviewed sources, no products sold.

Frequently Asked Questions
Common Questions About Biohacking Gear
Quick answers to the questions we get most often. Each guide has its own detailed FAQ section covering product-specific questions.
What is biohacking gear, and does any of it actually work?
Biohacking gear covers a wide range of consumer devices (infrared saunas, cold plunge tubs, red light therapy panels, hyperbaric chambers, PEMF mats, and more) that people use to try to improve recovery, sleep, energy, and longevity. The short answer is that some categories have strong peer-reviewed evidence behind them, some have moderate evidence, and some have mostly marketing. Our guides are organized to flag which is which for each category we cover.
How does BioHackBuyer pick its top recommendations?
For each category, we start with the published research, then aggregate verified owner reviews, independent third-party tests where they exist, and manufacturer specifications. We rank within price tiers and overall. The full process is documented on our Research Methodology page. Brands cannot pay for placement, and we recommend products without affiliate programs when the evidence points that way.
Are BioHackBuyer reviews written by experts?
Our reviews are research-aggregated editorial work, not first-person product testing. We say so on our About page. We do not personally own and operate every product we recommend. What we do is synthesize what independent testers, long-term owners, clinicians, and researchers have found, and present it clearly. This is honest about what we are and what we are not.
Is this site medical advice?
No. Nothing on BioHackBuyer is medical advice, and nothing here is intended to diagnose, treat, cure, or prevent any condition. Biohacking gear can affect your health. Some categories interact with medications, medical conditions, or pregnancy in ways the research has not fully mapped. Before starting any new protocol, especially if you have a medical condition, take medication, are pregnant or nursing, or have a history of cardiovascular, neurological, or skin conditions, talk to a qualified clinician who knows your specific situation.
Do you make money when I buy through your links?
Yes. BioHackBuyer participates in affiliate programs including Amazon Associates. When you click a product link on our site and buy something, we may earn a small commission at no extra cost to you. This is how the site stays free. We are transparent about this on our Affiliate Disclosure page. Affiliate income keeps the site running. It does not buy influence over what we recommend.
How often do you update your guides?
We revisit published guides on a regular schedule and update them when the data changes. New products launch, brands reformulate or change manufacturers, and new research gets published. A guide that has not been touched in 18 months is not a guide you should trust. Each guide shows its published and last-updated dates so you can see how current the information is.
