Yes
Your brain waves are measured.
Your sleep cannot be measured in mcm.
Sleep latency-- The amount of time that it takes to fall asleep. Sleep latency is measured in minutes and is important in diagnosing depression.
Sleep stages are defined in terms of brainwave patterns, which can be measured by an electroencephalograph (EEG).

The answer to the question "How many hours does the typical person sleep each week?" is measured in hours. There are 168 hours in a week, so you would calculate the total number of hours of sleep a typical person gets in a week by adding up the hours they sleep each night.
Sleep stages are measured using polysomnography, a comprehensive test that records brain activity, eye movement, muscle tone, heart rate, and breathing patterns. Electroencephalography (EEG) is primarily used to track brain waves, helping to identify different sleep stages such as REM and non-REM sleep. Additionally, other sensors monitor physical changes, providing a complete picture of the sleep cycle and its various stages. This data allows for the assessment of sleep quality and any potential sleep disorders.
Important parts of the polysomnography study include measurements of: heart rate. airflow at the mouth and nose. respiratory effort. sleep stage (light sleep, deep sleep, dream sleep, etc.). oxygen level in the blood,using a.(ear oximetry).
for adults like 7 to 8 while teenagers 8 to 9 and infants about 16 hours of sleep a week
Blood pressure is also measured: sometimes episodes of sleep apnea can dangerously elevate blood pressure.
