The Sleep Cycle Explained

Understanding Sleep Stages

Stage 1 (N1): Light sleep, transition (5-10 minutes)
Stage 2 (N2): Deeper sleep, body temperature drops (20 minutes)
Stage 3 (N3): Deep sleep, physical restoration (30 minutes)
REM Sleep: Dreaming, memory consolidation, mental restoration (10-60 minutes)

Full cycle: ~90 minutes
Cycles per night: 4-6 cycles

Optimal wake time: End of a cycle (after 6, 7.5, or 9 hours)

The Perfect Sleep Environment

Temperature

Ideal: 60-67°F (15-19°C)

Why it matters:

• Body temperature drops during sleep
• Cooler room facilitates this process
• Too warm = frequent waking

Solutions:

• Use breathable bedding
• Ceiling fan or AC
• Keep window slightly open
• Moisture-wicking pajamas

Darkness

Importance: Light suppresses melatonin (sleep hormone)

How to achieve:

• Blackout curtains or blinds
• Cover or remove LED lights (alarm clocks, electronics)
• Eye mask if needed
• Block light from under door

Screen light: Blue light is worst offender

• No screens 1-2 hours before bed
• Use blue light filters if must use devices
• Enable night mode on phones/computers

Noise

Ideal: Quiet or consistent white noise

Solutions:

• Earplugs (if total silence preferred)
• White noise machine
• Fan for consistent background sound
• Soundproofing if street noise is an issue

Comfort

Mattress:

• Replace every 7-10 years
• Medium-firm best for most people
• Side sleepers: slightly softer
• Back/stomach sleepers: firmer

Pillows:

• Replace every 1-2 years
• Height depends on sleep position
• Side sleepers: thicker pillow
• Back sleepers: medium thickness
• Stomach sleepers: thin or no pillow

Bedding:

• Breathable materials (cotton, linen, bamboo)
• Keep bedroom for sleep and sex only
• Remove clutter

The Perfect Bedtime Routine

Give changes 2-4 weeks to work. Your sleep won't improve overnight (ironically), but with patience and consistency, you'll transform your sleep and, by extension, your entire life.

Great sleep isn't a luxury—it's a necessity. Prioritize it, and watch every other area of your life improve.
