Delta Waves

Scientists have recently discovered that slow waves of electrical activity found during sleep help to clean the brain – mopping up toxic metabolic waste and harmful byproducts from our daily lives. These slow delta waves differentiate between our conscious and unconscious minds and are therefore only present during the deepest phases of sleep.

Studies suggest that delta waves are vital for our bodies ability to cleanse itself; they beckon waves of cerebrospinal fluid to flow in and out of the brain – like a tide – every 20 seconds. Bathing the brain in this fluid is crucial for our health and helps to prevent neurodegenerative diseases such as Alzheimer’s and Dementia.
