The ________ wave is characteristic of stage 1 sleep.
Question: The ________ wave is characteristic of stage 1 sleep.
The alpha wave is characteristic of stage 1 sleep. Alpha waves are low-amplitude, high-frequency brain waves that are associated with relaxation and wakefulness. During stage 1 sleep, the brain begins to slow down, but it is still relatively active. Alpha waves are the dominant brain wave pattern during this stage of sleep.
Stage 1 sleep is the lightest stage of sleep, and it is easy to wake someone up during this stage. However, if the person is not disturbed, they will quickly move on to stage 2 sleep.
The other stages of sleep are:
- Stage 2 sleep: This stage is characterized by sleep spindles and K-complexes, which are bursts of electrical activity in the brain.
- Stage 3 sleep: This stage is also known as deep sleep. It is characterized by slow delta waves.
- Stage 4 sleep: This is the deepest stage of sleep. It is characterized by even slower delta waves than stage 3 sleep.
- REM sleep: This stage is known as rapid eye movement sleep. It is characterized by rapid eye movements, increased brain activity, and dreaming.
Sleep is an essential part of a healthy lifestyle. It allows the body and mind to rest and repair themselves.
