What is Slow Wave Sleep?
Slow Wave Sleep, also known as Delta sleep, is the sleep stage where your brain is producing its slowest brainwaves, also called Delta waves. While the brain is producing these Delta waves, it is peacefully resting without any thoughts or worries. During this stage of sleep, the body doesn’t move, but it is hard at work to complete some important healing processes. These processes, including growth hormone secretion causing growth and healing, DNA repair, immune system re-balancing, and the removal of harmful material from nerve cells, are strongest in young people, who get the most Slow Wave Sleep, but gradually deteriorate with age. In fact, by their mid to late forties, most people have lost 60-70% of their Delta sleep, and by their seventies it is mostly, if not all, gone. Without this deep level of sleep, your body loses out on some of its most important healing processes.
