What occurs during stage 1 sleep?

The most pronounced physiological changes in sleep occur in the brain. The brain uses significantly less energy during sleep than it does when awake especially during non-REM sleep. In areas with reduced activity the brain restores its supply of adenosine triphosphate (ATP) the molecule used for short-term storage and transport of energy. In quiet waking the brain is responsible for 20% of the body’s energy use thus this reduction has a noticeable effect on overall energy consumption.

NREM sleep was divided into four stages in the Rechtschaffen and Kales (R&K) standardization of 1968. That has been reduced to three in the 2007 update by The American Academy of Sleep Medicine (AASM). • Stage 1 – occurs mostly in the beginning of sleep with slow eye movement. This state is sometimes referred to as relaxed wakefulness. Alpha waves disappear and the theta wave appears. People aroused from this stage often believe that they have been fully awake.
