What level of consciousness is associated with Theta Waves?

Theta waves are typically associated with light sleep and the relaxed awake state. They are brainwave patterns that oscillate between 4 to 8 Hz and are often present during the transitions between wakefulness and sleep, as well as during dreaming. In light sleep, especially during the stages of NREM sleep, theta waves become prominent, indicating a state where the individual is not fully awake but not in deep sleep either. This brainwave pattern is also prevalent during meditation and states of relaxation, making it a time associated with creativity and insightful thinking.

In contrast, deep sleep is characterized by delta waves, while the comatose state exhibits very low brain activity, often featuring a lack of discernible waves. The relaxed awake state is more associated with alpha waves, which are prominent when a person is awake but relaxed and calm. Therefore, theta waves are distinctly linked to light sleep, making this the appropriate answer.
