The first three stages of sleep are characterised by three types of brainwaves: alpha waves, theta waves and delta waves. The former are typically recorded when we’re in the process of falling ...

The technique’s name is based on the science behind alpha waves—a brain wave that presents ... To maximize the success of this sleep technique, set yourself up for optimal sleep by eating ...

The headband emits acoustic simulation that responds to the user’s brainwaves to induce sleep by suppressing alpha waves, which occur when the brain is in a relaxed state but still awake.

As part of the study published in SLEEP, researchers at the University of Surrey manipulated the brain waves known as the alpha and theta oscillations in 18 healthy young adults while they slept.

Alpha waves (8-12 Hz) happen when we are relaxed with eyes closed, as in meditation. Theta waves (4-7 Hz) are common in the lighter stages of sleep or the transition from waking to sleeping.

Alpha waves (8-12 Hz) happen when we are relaxed with eyes closed, as in meditation. Theta waves (4-7 Hz) are common in the lighter stages of sleep or the transition from waking to sleeping.

This alpha brainwave is what is present when we are relaxed and conscious. To induce sleep (a delta brainwave of 5 hertz), a person may need to devote at least 45 minutes, in a relaxed position, ...
