How Sleep Works: Understanding the Sleep Cycle

Sleep occurs in cycles, each consisting of multiple stages:

1. Non-REM Sleep:

1. Stage 1: A light sleep phase where the body begins to relax.
2. Stage 2: Deeper relaxation and slower brain activity occur.
3. Stage 3: This is deep sleep, crucial for physical restoration.

REM Sleep (Rapid Eye Movement):

• Dreams occur during REM sleep, essential for emotional health and cognitive functions.

Each cycle of nocturnal sleep lasts about 90 minutes and is repeated approximately 4 to 6 times per night. Quality sleep means experiencing all stages in balanced proportions.

Several factors interfere with the ability to fall and stay asleep, including:

• Stress and Anxiety: Racing thoughts make it hard to relax.

• Technology Use: Blue light from screens suppresses melatonin, a sleep-regulating hormone.
• Irregular Schedules: Shift work or inconsistent bedtime routines confuse the body’s internal clock.

Sleep deprivation often manifests in subtle ways, such as:
