The secret of deep sleep
Sleep is not just a moment of rest for the body – it is a vital process for brain health. Researchers have discovered that during the deep sleep phase, the brain activates a unique “cleansing” mechanism. Through the circulation of cerebrospinal fluid, it removes toxic waste and harmful proteins that accumulate during the day. This process functions as a “natural wash” of the brain, keeping nerve cells healthy.
Link to neurodegenerative diseases
One of the most important discoveries is related to the connection between this process and diseases such as Alzheimer's or Parkinson's. Scientists have observed that when this "washing mechanism" does not work properly, toxins accumulate and affect memory and other cognitive functions. This is why a lack of deep sleep is seen as a risk factor for the development of neurodegenerative diseases.
New technologies at the service of sleep
Based on this knowledge, innovative devices are being developed that aim to stimulate the brain's natural cleansing process. Wearable devices or non-invasive technologies use mild electrical impulses or sound waves to induce deep sleep and enhance the circulation of cerebrospinal fluid. The idea is that by helping the brain cleanse itself better at night, serious diseases such as Alzheimer's could be prevented or slowed down.
A new horizon for brain health
This discovery opens up a new field in medicine and neuroscience. In the future, sleep therapy could become an essential part of preventive treatments for memory and mental health. The brain will no longer be seen simply as an organ of thought, but also as a complex system that requires regular maintenance – and deep sleep will be key to this maintenance.
