The scenario of brushing your teeth and preparing for bed is associated with a state of relaxation and transition from wakefulness to sleep. During this time, the brain typically produces alpha waves. Alpha waves are present when a person is awake but in a calm, relaxed state, often with closed eyes, and they may also occur just before falling asleep.

In this phase, the mind is not fully engaged in cognitive tasks but is still alert enough to maintain a level of consciousness. This state is conducive to winding down and preparing for sleep, which is why alpha wave activity is most prevalent during these activities.

In contrast, fast beta waves are associated with active thinking, alertness, and engagement, while theta waves are more commonly linked to light sleep and very relaxed states, often occurring during the early stages of sleep or deep meditative states. Delta waves represent deep sleep and are not experienced during the preparatory activities before bed. Thus, the ideal representation of brain wave activity during the routine of brushing teeth and preparing for sleep aligns best with the presence of alpha waves.
