In recent years, doctors have encountered a surprisingly large number of working individuals with similar symptoms. There's no apparent disease, basic test results are usually normal, but they feel their brains are "not as fresh as before," experiencing fatigue, poor concentration, shallow sleep, and brain fog that makes it difficult to perform as they used to. Many try to solve this by getting enough sleep or taking extended breaks, but the symptoms return once they return to their usual routine. This has led us to question whether the problem might not be "insufficient rest," but rather "the brain not truly resting," especially at the neurological level. Silence Heals Therefore, it is being discussed more often, not just as a concept of calmness, but as an approach that aligns with neuroscience principles. When the brain has a period of "silence" free from stimuli, it may enter a more restorative mode.
The human brain works in a rhythm, naturally alternating between periods of alertness and recovery. However, modern life puts the brain in a state of constant information reception—notifications, messages, online meetings, screen switching—requiring rapid and continuous responses.
When stimuli come in frequently, the brain uses more energy for "switching modes," and the body's stress response system can be repeatedly stimulated, leading to accumulated fatigue. Many people therefore feel like they've rested but haven't truly recovered because the body may stop...but the brain hasn't.
Stanford explains that “zoom fatigue” isn't caused by any single platform, but rather by the way video communication works, requiring the brain to exert more effort, such as nonverbal cues, viewing distances that are too close, constantly seeing one's own face, and restricted movement.
An important point for working professionals is that this isn't a sign of "not having enough stamina," but rather a biological truth: the brain compensates for the lack of face-to-face communication, such as context, body language, and natural rest periods, thus using more energy and becoming more fatigued.
Dopamine plays a role in motivation and the feeling of "rewarding." The digital world makes "small rewards" come quickly and frequently. Notifications, messages, scrolling feeds, switching content—these can cause the brain to become accustomed to rapid stimuli, reducing the satisfaction of ordinary things.
This is why some people experience burnout, boredom, or a lack of engagement with their work, not because of a problem with their "ability," but because their nervous system is stimulated too frequently and becomes fatigued. Therefore, Silence Heals isn't about escaping technology, but about "re-setting the rhythm" to allow the brain to return to balance.
Interesting research in animal models has been found to correlate "silence" with the hippocampus (involved in memory and emotions). The study found that "silence" is associated with increased proliferation of progenitor cells and the generation of new neurons in this area.
In real life, we don't necessarily need to immediately interpret "silence leads to new brain cell growth" in humans, but we can use this evidence as a reflection that... Reducing stimuli It may be a state more conducive to nervous system recovery than being in a constantly stimulated world.
The World Health Organization (WHO) classifies burnout in ICD-11 as “a chronic, unmanaged stress condition in the workplace” and emphasizes that it is a phenomenon in the workplace context, not a direct medical disease.
From a Preventive Medicine perspective, what we want to be aware of is that when fatigue accumulates to the point where it interferes with sleep, concentration, mood, and recovery ability, the body may begin to lose balance in its stress response, leading to a chain reaction affecting energy levels and quality of life. Harvard Health clearly explains the mechanisms of the stress response and the role of hormones like cortisol.
If you want to start without pressure, try viewing Silence Heals as a “nervous system rest” rather than an activity for calm.
A method that many people can follow.
Consistency is more important than length of time, because the nervous system responds better to repeatable behaviors.
If you experience these symptoms for 4–8 weeks or more.
These symptoms don't always mean there's a disease, but rather a sign that the body's "recovery system" may not be functioning optimally, and it's time to start taking preventative care seriously.
In W9 Wellness's philosophy, silence is "one tool," but not the whole answer, because chronic brain fatigue can be related to multiple systems, such as sleep patterns, accumulated stress, low-grade inflammation, or certain imbalances in the body.
Therefore, in some cases, doctors may consider a more in-depth evaluation (as appropriate for each individual) to gain a clearer understanding of the root causes of "rest that doesn't help with recovery," based on the principles of Personalized & Preventive Wellness and avoiding generalizing that all symptoms are due to mental or disciplinary factors.
Our key principle is that we don't try to "force you to be better," but rather to "allow your nervous system to recover better," so that you can regain your natural energy and vitality.
When was the last time you truly gave your brain a “non-stimulatory” rest—and how different did you feel that time compared to other days?
What is SilenceHeals?
The concept is to create periods of reduced stimulation (noise/information/screens) to allow the brain to rest and recover neurologically.
Does it have to be completely silent?
It's not necessary. The main meaning is "reduce stimuli that accelerate the brain." Some people can start with nature sounds or being in a quiet place.
Why do I still feel tired even after resting?
Because sometimes the body gets rest, but the brain remains alert due to continuous stimuli, or the sleep/stress cycle may be disrupted. Harvard Health+1
Can zoom fatigue be cured?
This can be helped by scheduling breaks during meetings, turning off self-view occasionally, moving around, and switching to phone/offline when appropriate, as described by Stanford. Stanford News
How "real" is silence to benefit the brain?
There is biological evidence (especially experimental work) that suggests that reducing stimuli may facilitate the recovery of certain brain regions, such as the hippocampus. PMC However, in humans, it should be interpreted rationally and emphasize sustainable application.
