Science of Sleep - Lessons of Royce

THE SCIENCE OF SLEEP

(From Royce's Footnotes)

I have had the fruitful opportunity to receive a lecture on the technicalities of sleep, sponsored by my company, Tropicana Corporation Berhad.

The speaker is also known as a sleep doctor, or sleep specialist, which can also be your GP or Ear, Nose & Throat specialist. There is also the American Board of Sleep Medicine - http://absm.org/ to understand a collective of Sleep scholars.

R.E.M - Rapid Eye Movement

There are 5 stages of REM sleep and we begin our sleep by entering heavier, uninterrupted sleep at the start and progress into longer alternating intervals of light REM sleep and Deep (Non-REM sleep).

TOOLS OF THE TRADE

EEG (electroencephalogram) to measure and record brain wave activity

EMG (electromyogram) to record muscle activity such as face twitches, teeth grinding, and leg movements; it also helps in determining the presence of REM stage sleep.

EOG (electro-oculogram) to record eye movements; these movements are important in determining the different sleep stages, particularly REM stage sleep.

EKG (electrocardiogram) to record heart rate and rhythm

Nasal airflow sensor to record airflow

Snore microphone to record snoring activity

FACTORS AFFECTING SLEEP

Not covered in the lecture but I found this chart more relevant to daily life.
