Delta waves are associated with deep sleep, also known as stage 3 or 4 of non-REM sleep. If an individual enters deep sleep less than an hour after falling asleep, delta waves will be detected in their brain waves. Beta waves are associated with high levels of mental activity, alpha waves are associated with relaxation, and theta waves are associated with light sleep and drowsiness.
