What brain wave frequency is typically linked to relaxation and daydreaming?

Alpha waves are brain wave frequencies that range from 8 to 12 Hz and are typically associated with a state of relaxation and calmness, often occurring when a person is awake but relaxed, such as during meditation or daydreaming. These waves reflect a brain that is not actively engaged in intensive cognitive tasks but rather is in a state of peacefulness and tranquility.

The presence of alpha waves suggests a meditative or relaxed state, indicating that the brain is preparing to transition between wakefulness and sleep, or simply engaging in a less active form of thought. This is why they are closely associated with relaxation techniques and states of mindfulness, making them the correct answer for this question.
