Explore the science of photobiomodulation (PBM) and red light therapy. Learn if whole-body light beds actually improve exercise recovery and athletic performance.
Biohacking isn’t just about adding new things like light therapy; it might be about removing the internal constraints, like molecular brakes, that are holding us back.
The science behind bio hacking and what actually works.
Photobiomodulation, often referred to as PBM or red light therapy, is a field of study focused on using specific wavelengths of red or near-infrared light to trigger cellular changes. While it is often marketed as a biohacking tool for sharpening the brain and improving sleep, the core concept involves using light to influence biological processes. Despite its futuristic reputation, researchers are still working to determine how these light wavelengths translate into measurable health benefits.
According to a major review published in January 2025, whole-body photobiomodulation beds did not show clear benefits for exercise performance or recovery. After screening nearly two hundred studies, researchers found that these high-tech light beds didn't perform significantly better than doing nothing at all. While the marketing suggests they are essential for athletes, the current data indicates that the promise of this specific biohack may be hitting a brick wall.
While red light therapy and near-infrared light are popular in the biohacking community, the shiny marketing often outpaces actual lab results. Influencers may claim it acts as a fountain of youth for muscles and brain health, but scientific reviews suggest a more cautious approach. As discussed in Red Light and the Molecular Brake, the evidence for whole-body PBM providing a competitive edge in athletic recovery remains inconclusive based on recent 2025 data.

Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!
@ladyInfinity
I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.
@jayallen
The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.
@Raguipa
What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.
@colonyofcreatorsNGO
I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.
@BeFreed user
It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.
@austinakon
I love this app. Used it for several days and I cannot stop listening. Such a great way to start.
@jcrules328
I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.
@DanielCZ
I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.
@BeFreed user
I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.
@Brad
I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!
@BeFreed user
The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.
@jayallen
BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.
@BeFreed user
At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!
@matteo77
BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
