Caffeine is the most consumed stimulant worldwide, and there is great interest in understanding its neurophysiological effects. Resting-state electroencephalography (EEG) studies suggest that caffeine enhances arousal, which suppresses the spectral power of alpha frequencies associated with reduced alertness.
Can alpha waves cause anxiety?
Anxiousness is associated with decreased alpha waves, increased beta waves, and can be affected by low delta and theta waves.
