Deep Sleep: What is it and Why do I need it?

by Bryan Dewhurst on April 04, 2020

Also known as “slow wave sleep”, Deep Sleep is when your brain waves are at their lowest frequency, meaning you don’t respond to stimuli as quickly and you are at your hardest to wake up. It is known as the “physically restorative” stage of sleep, meaning it is during this time that your muscles relax, your heart rate decreases, and your brain clicks pause on the countless thoughts that cycled through your head during the day.

Is Deep Sleep really necessary?

If you want to function throughout the day, then yes, Deep Sleep is necessary. It is during this time when your body restores and heals itself. Another thing to note is that 95% of the human growth hormone is produced during deep sleep. This is why we’ve gotten used to hearing “get enough sleep if you wanna grow taller” especially when we were younger. In case you’re still not convinced, here are some of the benefits/effects of deep sleep:


  • Energy is restored
  • Metabolism and blood sugar levels are balanced
  • Tissues and bones are repaired
  • The immune system is strengthened
  • Cells are regenerated
  • Blood supply is Increased to both the heart and the muscles
  • The brain is detoxified


What if I fail to get deep sleep?
Sleep deprivation has profound effects on health. Failing to get enough sleep can significantly impact the body and, more importantly, the brain. 
When deep sleep is compromised, consider these consequences:
 (Higher risk for)
  • Obesity
