Sleep Dictionary: Understanding Common Sleep Terminology

When it comes to understanding sleep, a few terms often pop up that might leave you scratching your head. Let’s break down some of the most commonly used sleep terms in a friendly, easy-to-understand way.

Sleep Cycle

A sleep cycle refers to the journey your body takes through different stages of sleep, typically lasting about 90 minutes. Each cycle consists of light sleep, deep sleep, and REM (Rapid Eye Movement) sleep, which is crucial for memory and mood regulation.

REM Sleep

REM sleep is the stage where most dreaming occurs. It’s characterized by rapid movements of the eyes and increased brain activity. This phase is vital for cognitive functioning, emotional health, and learning.

Sleep Apnea

Sleep apnea is a potentially serious sleep disorder where breathing repeatedly stops and starts during sleep. People with this condition often snore loudly and feel tired even after a full night’s sleep.

Circadian Rhythm

Your circadian rhythm is like your internal clock, regulating the cycle of sleeping and waking. This natural process responds to light and darkness, influencing when you feel alert or sleepy.

Sleep Hygiene

Sleep hygiene refers to the habits and practices that contribute to a good night’s sleep. This includes creating a comfortable sleep environment, maintaining a consistent sleep schedule, and avoiding caffeine close to bedtime.

Insomnia

Insomnia is the difficulty in falling asleep or staying asleep, despite having the opportunity to sleep. It can be caused by stress, anxiety, or various medical conditions.
