If you have trouble sleeping, the chances are that you will have tried just about anything to get some quality shut-eye. Cups of chamomile tea, hours of meditation, lavender baths – but sometimes sleep is still elusive even after trying everything you know.


Which is where delta waves come in.


A delta wave is a high amplitude brain wave emitting a frequency between one to four hertz. These brain waves are emitted from the thalamus during the third stage of sleep or the deep sleep stage.


When we are in the delta stage, we release anti-ageing hormones such as DHEA and melatonin while reducing stress hormones such as cortisol. So, delta wave sleep is important for staying youthful and stress-free!


As the brain cycles through the different sleep stages, different levels of brain activity occur in each one.


  • Small, fast beta waves are produced in the initial stage of sleep, followed by slower alpha waves.
  • Slow, high amplitude theta waves are produced during the first stage of light sleep, lasting approximately 7-10 minutes.
  • Slow, deep delta waves are produced during the deep sleep stage during which people are much more unresponsive. It is during this stage that memories are consolidated, and the brain and body are regenerated.


So, what happens when we listen to music containing delta waves?


Sound can be used to increase these regenerative brain waves by replicating the effect that the delta waves have on your brain as it sleeps. When we listen to sounds containing delta waves, the brain slows down and prepares itself for deep, regenerative sleep. Interestingly, research indicates that women produce more delta wave activity than men, though it is not certain why this is.


So, if you have been having trouble sleeping, perhaps try listening to a soundtrack with delta waves through a smart pillow-like Zeeq?
