The functioning of the Glymphatic System

The glymphatic system uses the flow of cerebrospinal fluid and interstitial fluid to remove metabolic wastes and other substances from the brain. During sleep, the space between brain cells expands by up to 60%, facilitating a more efficient exchange between these two fluids.

This "cleansing" process is driven by the pulse of blood in the circulation, which helps maintain the movement of interstitial fluid through the channels formed by astrocytes.

In this way, the glymphatic system takes advantage of sleep to effectively eliminate toxins and harmful proteins, such as beta-amyloid associated with Alzheimer's.

The importance for Brain Health

Proper functioning of the glymphatic system is crucial for brain health and the prevention of neurodegenerative diseases.

Some research suggests that the deterioration of this system could be related to problems with memory, concentration, headaches, stress and anxiety.

Therefore, taking care of your sleep, staying hydrated, and consuming foods rich in magnesium and fiber are important strategies to promote the activity of the glymphatic system and, consequently, preserve long-term mental and brain health.
