What is a Delta Sleeper?
A Delta Sleeper is one who achieves the high amplitude extremely slow brain wave activity of stages 3 and 4 Non-Rapid Eye Movement (NREM) sleep. During Stage 3, our brain produces extremely slow waves with occasional bursts of faster brain wave activity. As we enter Stage 4, our brains produce extremely slow waves almost exclusively. These stages are known as “Deep Sleep” or “Delta Sleep”.
