The deep sleep stage (or slow-wave sleep stage) gives rise to delta waves within the brain which are described as high amplitude brain waves with the slowest frequency. These waves are thought to emerge from the brain’s thalamus and are the most prominent during dreamless sleep as well as the deepest stages of meditation. They are also tied to the body’s unconscious functions such as regulating heart rate. The right amount of delta waves sleep is vital to our overall health.
These brainwaves are thought to aid healing and regeneration within the body. When delta wave activity is limited, individuals experience restless sleep and wake up feeling tired. On the flip side, too much delta wave activity is also an issue. An overabundance could result in severe attention deficit hyperactivity disorder and learning difficulties. Traumatic brain injury can also cause the brain to produce too many delta waves, which would make it hard for the person impacted to remain awake.
The Features of Deep Sleep
– Electroencephalogram (EEG) demonstrates presence of delta waves by tracking and recording brain wave patterns.
– Consolidation of memories takes place.
– High arousal threshold (aka difficulty of waking).
– Presumed restoration of body and brain.
How to Encourage Delta Waves Sleep
The best thing you can do is to allow yourself time to sleep by setting a consistent schedule. Adults need 7 to 9 hours of sleep per day. Some data suggests that exercise can increase or consolidate deep sleep. Aerobic activities such as jogging, running, and swimming are recommended by sleep specialists.
Sleep researchers are also currently working on identifying sound patterns that prompt the brain to produce more delta waves. Listen to some music that is believed to help achieve delta waves sleep below!
