Why are Delta Waves important?
I mean a third of your life? That’s a lot, but a good night’s sleep is vital to your overall health. Delta Waves play an important part of that sleep. Getting enough sleep is vital for health-promoting activities such as digestion, growth, and memory. By understanding our stages of sleep above, we can see how important sleep is and the role it plays in our overall well being. One factor in your sleep are the Delta Waves produced during deep sleep. They are high amplitude brainwaves, believed to be emitted from the thalamus and are key to unlocking the restorative deep sleep. They’re so helpful in bringing on deep sleep that delta waves have even been reproduced as musical binaural beats which you can listen to as you fall asleep.
What are they and why are they important?
Our brain sends out signals when we sleep to different parts of the mind and body. These signals help to begin restorative functions. Delta waves are generated during our deepest dreamless sleep. They are low frequency and deeply penetrating brainwaves. They stimulate healing and regeneration, which is why deep, restorative sleep is so essential to the healing process. Several studies have linked the healing aspects of sounds to healing processes in humans and other animals. The low rhythmic purr of cats is not only used as an expression of contentment, but also to calm and heal.
What stage do delta waves occur?
During sleep, delta waves are slowly released in the first two stages of light where brain activity is lower. As you transition into stages 3 and 4 (deep sleep), delta waves increase and quicken in frequency. If you were to be abruptly awakened while in the deep sleep cycle, you’d wake up feeling groggy and disorientated.
How do delta waves affect sleep?
In the delta state, your brainwaves support restorative cycles where your energy levels are restored and the body recharges itself through tissue and cell growth. Studies have also shown that while you’re in stages 3 and 4, your brain waves play an integral part in you feeling alert and rejuvenated in the morning.
Other facts about how delta waves help us
- Anti-aging hormones like melatonin and DHEA are released when we are in a delta state, so more deep sleep equals a youthful look!
- Babies spend more time in the delta state than adults. Even when they’re awake their delta waves are highly functional.
- Women display more delta wave activity than men
- Alcohol and drugs have a lasting effect on delta waves, sometimes changing the frequency or rate of release completely.
