Slow-Wave Sleep And Sleep Deprivation

Also known as SWS, Slow-wave sleep is the most restorative one, the deepest layer of sleep without any dreams. In the SWS phase, delta waves are emitted by your brain, and memory consolidation gets activated.

According to a recent study, short naps(30 minutes) do not help much for balancing out sleep deprivation as it does not reach the SWS phase. A longer nap, on the other hand, helps improve mental focus and clarity.
