As you fall asleep, the way your EEG wave patterns change as you go from being alert, to being relaxed, to being deep asleep as beta waves → alpha waves → delta waves.

An EEG or electroencephalogram is a test utilized to examine the electrical activity in your brain. The cells in the brain communicate with each other through electrical impulses and an EEG helps identify any associated possible issues. Hence, an EEG tracks and records brain wave patterns.  The shape of EEG wave pattern is established by the frequencies that combine to form the waveform as well as by their phase and voltage relationships. There are four basic EEG frequency patterns as follows: Beta waves (14-30 Hz), Alpha waves (8-13 Hz), Theta waves (4-7 Hz), and Delta waves (1-3 Hz). Beta waves are characterized by high-frequency, low-amplitude brain waves experienced in an awakened state. Alpha waves lies in the middle of the brain wave spectrum and is produced when an individual is not focusing too hard on anything and are relaxed. Delta waves are produced by the brain when an individual is in deep sleep.
