    Best quote from The Cortisol Rhythm: Understanding Stress and Circadian Health

    “

    Relaxation isn't just about peace of mind; it’s a physical process that lessens the effects of stress on your body by triggering a 'relaxation response' that is the physiological opposite of fight-or-flight.

    Frequently Asked Questions

    The cortisol rhythm is a natural circadian cycle where the hormone, produced by the adrenal glands, peaks in the morning to help you wake up and gradually declines throughout the day. This biological process is designed to help the body function and manage stress. When this rhythm is healthy, it allows for a natural transition from daytime alertness to evening rest, acting as a biological guide for your daily energy levels.

    Chronic stress disrupts the natural cortisol rhythm by keeping hormone levels elevated in the evening instead of allowing them to decline. This elevation is problematic because it blocks melatonin, the primary sleep hormone, creating a vicious cycle where poor sleep further fuels stress. Instead of fading into a lullaby for rest, the body stays stuck in a frantic loop that prevents the biological transition to sleep.

    The adrenal glands are responsible for producing cortisol, a hormone that is essential for the body's natural stress response. While often viewed negatively, cortisol from the adrenal glands is actually meant to help us navigate challenges. Under normal conditions, these glands follow a circadian rhythm that supports waking up and winding down, but modern stressors like information overload can cause these glands to maintain high hormone levels inappropriately.

    Information overload has become a significant modern stressor, with 69 percent of adults citing it as a major challenge in 2026. This constant influx of data contributes to chronic stress, which breaks the natural cortisol rhythm and keeps the body in a state of high alert. This biological stress response makes it difficult for many adults to function, as the constant pressure prevents the hormone levels from dropping as they should.

    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.
