Stage 1 sleep is characterized by a predominance of alpha and theta wave activity in the brain.

The stage of entering the state of sleep is also called stage 1 and is considered as a boundary between the waking state and sleeping.

In this stage, the rhythm alpha predominates, which tends to slow down and show the presence of waves called theta, which are of greater amplitude.

Alpha activity is a pattern that results from a person resting and relaxing.

Theta waves are broad, low-frequency waves that would indicate a state of extreme relaxation and drowsiness.

Eye movements at this stage are slow and muscle tone drops. Phase I is short-lived and occupies about 3-5% of sleep.

Therefore, we can conclude that in stage 1 of sleep the alpha waves would be combined, with a new activity, called theta.
