Detailed explanation-1: -Alpha waves are seen in the electroencephalogram (EEG) during a normal wakeful state where the subject is quietly resting. Beta EEG are present when a person is alert/attentive and thinking actively. Theta rhythm (Stage 1) of sleep is present during the transition from wakefulness to sleep.
Detailed explanation-2: -Alpha waves are typically found in people who are awake but have their eyes closed and are relaxing or meditating. Theta waves: have a frequency range from three to eight Hz and an amplitude of 50 to 100 µV. Theta waves are associated with memory, emotions, and activity in the limbic system.
Detailed explanation-3: -Reduced Anxiety Since alpha brainwaves are associated with relaxed, calm, and restful mental states, it does not come as much of a surprise when alpha waves were linked to lower anxiety and stress.
Detailed explanation-4: -Alpha (8 to 12Hz): The posterior dominant alpha rhythm is characteristically present in normal awake EEG recordings in the occipital head region. It is the defining feature of the normal background rhythm of the adult EEG recording.
