Sleep Science Fundamentals
Sleep Architecture
A normal sleep cycle lasts approximately 90 minutes and repeats 4-6 times per night:
SLEEP CYCLE STRUCTURE (one ~90-minute cycle)
=============================================
AWAKE ----+
|
NREM 1 ---+--- Light sleep (5-10 min) - easily awakened
|
NREM 2 ---+--- True sleep onset (10-25 min) - body temp drops
|
NREM 3 ---+--- Deep/slow-wave sleep (20-40 min) - physical restoration
|
REM ------+--- Dream sleep (10-60 min) - mental restoration
|
[Cycle repeats]
Early night: More deep sleep (NREM 3)
Late night: More REM sleep
Sleep Duration Recommendations (National Sleep Foundation)
| Age Group | Recommended | May Be Appropriate | Not Recommended |
|---|
| Teenager (14-17) | 8-10 hours | 7-11 hours | <7 or >11 |
| Young Adult (18-25) | 7-9 hours | 6-10 hours | <6 or >10 |
| Adult (26-64) | 7-9 hours | 6-10 hours | <6 or >10 |
| Older Adult (65+) | 7-8 hours | 5-9 hours | <5 or >9 |
Circadian Rhythm
Your internal body clock runs on approximately a 24-hour cycle, regulated by:
Zeitgebers (time cues):
- Light (strongest cue) - Bright light in morning advances clock; light at night delays it
- Meal timing - Regular meals reinforce circadian rhythm
- Physical activity - Exercise timing signals the body clock
- Social interaction - Consistent social schedules help regulate rhythm
- Temperature - Core body temperature naturally dips at night
Chronotype:
- Early bird (lion): Natural sleep ~9:30 PM - 5:30 AM, peak energy morning
- Intermediate (bear): Natural sleep ~11 PM - 7 AM, peak energy mid-morning
- Night owl (wolf): Natural sleep ~12:30 AM - 8:30 AM, peak energy afternoon/evening

Bedroom Environment Optimization
Temperature
- Optimal range: 60-67F (15.5-19.5C)
- Core body temperature must drop 2-3F to initiate sleep
- A warm bath 1-2 hours before bed paradoxically helps (vasodilation cools core)
- Layer bedding so you can adjust during the night
- Consider cooling mattress pads if you run hot
Light
- Goal: As close to pitch darkness as possible
- Blackout curtains or cellular shades
- Cover LED lights on electronics with tape
- Eye mask as backup (silk or contoured)
- Nightlight only if necessary (red/amber, never blue/white)
- Dawn simulation alarm clock for gentle waking
Sound
- Goal: Consistent, non-stimulating sound environment
- White noise machine or fan for consistent background
- Earplugs (NRR 30+ for noisy environments)
- Address structural noise issues (weather stripping, rugs)
- Avoid falling asleep to TV or podcasts (variable stimulation)
Air Quality
- Open window slightly if possible (fresh air and slight cooling)
- Air purifier if allergies are an issue
- Humidity: 30-50% (humidifier or dehumidifier as needed)
- Clean bedding weekly (dust mites are a common sleep disruptor)
Mattress and Pillow Guide
| Sleep Position | Mattress Firmness | Pillow Loft |
|---|
| Back sleeper | Medium to medium-firm | Medium loft |
| Side sleeper | Medium to medium-soft | High loft (shoulder gap) |
| Stomach sleeper | Firm | Low loft or flat |
| Combination | Medium | Adjustable loft |
Replace mattress: Every 7-10 years or when sagging/uncomfortable
Replace pillows: Every 1-2 years
Sleep Schedule Design
Calculating Your Ideal Sleep Window
SLEEP SCHEDULE CALCULATOR
===========================
Step 1: Required wake time (work/life): ___:___ AM
Step 2: Target sleep duration: ___ hours
Step 3: Sleep onset latency (time to fall asleep): ~___ min
Step 4: Calculate bedtime:
Wake time - sleep duration - onset latency = bedtime
Example: 6:30 AM - 8 hrs - 15 min = 10:15 PM bedtime
Step 5: Wind-down routine start:
Bedtime - 60 min = start dimming lights, begin routine
Example: 10:15 PM - 60 min = 9:15 PM start routine
MY SCHEDULE:
9:__ PM - Begin wind-down routine
__:__ PM - In bed, lights out
__:__ AM - Wake time (alarm)
__:__ AM - Out of bed (no snooze)
__:__ AM - Bright light exposure
Adjusting Your Schedule (Gradual Shifting)
- Shift bedtime and wake time by 15-30 minutes every 2-3 days
- Do NOT try to shift by more than 1 hour at once
- Use morning light exposure to anchor the new schedule
- Avoid sleeping in on weekends by more than 30-60 minutes
Sleep Restriction Therapy (for insomnia - use with caution)
This is a clinical technique. Consider working with a sleep specialist.
- Calculate actual sleep time (e.g., 5.5 hours)
- Set sleep window to match actual sleep time (not less than 5 hours)
- Pick fixed wake time; calculate bedtime (wake 6 AM - 5.5 hrs = 12:30 AM)
- Stay in bed ONLY during this window
- When sleeping 85%+ of time in bed for 5 days, extend window by 15 min
- Repeat until reaching target duration
Screen Time Management
Blue Light and Melatonin
- Blue light (450-495nm) suppresses melatonin production
- Even dim blue light within 2 hours of bed delays sleep onset
- The issue is both wavelength AND brightness
Screen Management Protocol
| Time Before Bed | Action |
|---|
| 3+ hours | No restrictions needed |
| 2 hours | Enable night mode / blue light filter on all devices |
| 1 hour | Reduce screen brightness to minimum; prefer non-screen activities |
| 30 min | Screens off completely |
| In bed | No screens whatsoever |
Blue Light Filter Settings
- iPhone/iPad: Settings > Display > Night Shift (schedule sunset to sunrise)
- Android: Settings > Display > Night Light
- Windows: Settings > Display > Night Light
- Mac: System Preferences > Displays > Night Shift
- Browser: Install f.lux or use built-in reader mode
- Hardware: Blue-light-blocking glasses (amber/orange lens)
Relaxation Techniques Before Bed
10-Minute Wind-Down Routine
BEDTIME RELAXATION SEQUENCE
=============================
Minutes 1-3: GENTLE STRETCHING
- Neck rolls (30 sec each direction)
- Shoulder shrugs and release (5 reps)
- Seated forward fold (30 sec)
- Supine twist (30 sec each side)
- Legs up the wall (60 sec)
Minutes 4-7: BREATHING
- 4-7-8 breathing: 4 cycles
(Inhale 4 sec, hold 7 sec, exhale 8 sec)
Minutes 8-10: BODY SCAN
- Lie in bed, eyes closed
- Scan from toes to head
- At each area, tense for 3 sec, then release
- Notice the feeling of relaxation spreading
Cognitive Shuffle (for racing thoughts)
- Think of a random word (e.g., "garden")
- For each letter, picture unrelated things starting with that letter
- G: giraffe... guitar... glacier... grape...
- A: airplane... anchor... apricot... arrow...
- The randomness bores the brain's planning center into sleep
Sleep Journaling (Brain Dump)
Before bed, write for 5 minutes:
- Worries and to-dos for tomorrow (get them out of your head)
- Three things that went well today
- Tomorrow's plan (so you stop planning in bed)
Common Sleep Disruptors and Solutions
| Disruptor | Impact | Solution |
|---|
| Caffeine | Blocks adenosine for 6-8 hours | No caffeine after 2 PM |
| Alcohol | Fragments sleep, suppresses REM | Stop 3+ hours before bed |
| Late meals | Raises core temperature, causes reflux | Last meal 2-3 hours before bed |
| Stress/worry | Activates sympathetic nervous system | Brain dump journal, relaxation routine |
| Irregular schedule | Disrupts circadian rhythm | Fixed wake time 7 days/week |
| Napping too long | Reduces sleep pressure | Max 20 min, before 3 PM |
| Blue light | Suppresses melatonin | Screens off 30-60 min before bed |
| Bedroom too warm | Prevents core temp drop | Set thermostat to 60-67F |
| Clock watching | Creates anxiety about sleep | Remove visible clocks |
| Trying too hard | Performance anxiety about sleep | Paradoxical intention - try to stay awake |
Napping Strategy
Optimal Nap Durations
| Duration | Type | Benefits | Drawbacks |
|---|
| 10-20 min | Power nap | Alertness boost, no grogginess | Limited restorative benefit |
| 30 min | Avoid | Sleep inertia (grogginess) | Wakes from deep sleep |
| 90 min | Full cycle | Full restoration, creativity | Time-consuming |
Nap Rules
- Before 3 PM only (to preserve nighttime sleep drive)
- Set an alarm (prevent oversleeping)
- Dark, quiet environment
- If you have insomnia, avoid napping entirely
Sleep Tracking Interpretation
What to Track
- Bedtime and wake time
- Estimated sleep onset latency
- Number of awakenings
- Subjective sleep quality (1-10)
- Energy level next day (1-10)
- Factors (caffeine, alcohol, exercise, stress)

Sleep Efficiency = (Time asleep / Time in bed) x 100
Target: 85% or higher
This week's efficiency: ___%
Wearable/App Data Interpretation
- Consumer sleep trackers (Fitbit, Apple Watch, Oura) are reasonably accurate for total sleep time but less accurate for sleep stages
- Use trends over weeks, not individual night readings
- If tracker says you slept poorly but you feel fine, trust how you feel
- Clinical-grade measurement requires polysomnography (sleep study)
When to See a Sleep Specialist
Seek professional evaluation if you experience:
- Chronic insomnia (3+ nights/week for 3+ months)
- Loud snoring with witnessed breathing pauses (possible sleep apnea)
- Excessive daytime sleepiness despite adequate sleep time
- Restless, uncomfortable leg sensations at night
- Acting out dreams physically (REM behavior disorder)
- Falling asleep involuntarily during the day
- Sleep problems not improving with good sleep hygiene
- Reliance on sleep medication for more than a few weeks
