What frequency range do Delta Waves occur in?

Delta waves are known for their low frequency and are primarily associated with deep sleep, relaxation, and restorative processes in the brain. They occur within the frequency range of 0.5 to 4 Hz. This slow rhythm is important for various functions, including deep restorative sleep, healing, and regeneration.

In contrast, other frequency ranges such as 4-7 Hz (Theta waves), 8-12 Hz (Alpha waves), and 14-30 Hz (Beta waves) correspond to different brain states. Theta waves are associated with light sleep and relaxation, Alpha waves with calm wakefulness, and Beta waves are related to active thinking and problem-solving. Each of these frequencies has distinct characteristics and functions, making the correct identification of Delta waves crucial in understanding brain activity during different states of consciousness.
