What Is Sleep Hygiene?

Definition

Sleep hygiene encompasses:

Category Examples
Environmental factors Bedroom conditions, noise, light
Behavioral habits Sleep schedule, routines
Lifestyle choices Exercise, diet, substance use
Cognitive practices Worry management, relaxation

Why It Matters

  • Foundation for healthy sleep - Basic practices support all other treatments
  • Often overlooked - Many sleep problems stem from poor hygiene
  • Evidence-based - Research supports most recommendations
  • Within your control - Changes you can make today

Sleep Environment

The Ideal Bedroom

Factor Recommendation Why It Matters
Temperature 60-67°F (15-19°C) Body temperature drops during sleep
Darkness Completely dark Melatonin production requires darkness
Quiet < 30 decibels Noise disrupts sleep cycles
Comfort Quality mattress and pillow Physical comfort enables deep sleep

Optimizing Your Space

Light Control

  • Blackout curtains - Block street lights, early sun
  • Sleep mask - If complete darkness isn't possible
  • Remove electronics - LED lights, standby lights
  • Dim lights before bed - Signals body to prepare for sleep

Sound Management

  • White noise machine - Masks disruptive sounds
  • Earplugs - For noisy environments
  • Soundproofing - Heavy curtains, rugs, weatherstripping
  • Remove noise sources - Move ticking clocks, electronics

Temperature Regulation

  • Cool bedroom - Lower temperature than daytime
  • Breathable bedding - Natural fibers (cotton, linen)
  • Layer blankets - Adjust easily during night
  • Fan or air conditioning - Air circulation helps

Bed Association

  • Bed = Sleep only - No work, TV, or worry in bed
  • Leave if can't sleep - Return when sleepy
  • Comfortable setup - Invest in quality mattress and pillows

Sleep Schedule

Consistency Is Key

Practice Recommendation
Wake time Same time every day, including weekends
Bedtime Consistent, allowing 7-9 hours
Variation No more than 1 hour difference on weekends

Why Consistency Matters

  • Regulates circadian rhythm - Body learns when to sleep
  • Improves sleep quality - More efficient sleep cycles
  • Reduces insomnia - Less time lying awake
  • Easier mornings - Natural wakefulness

Finding Your Schedule

  1. Determine wake time - Based on work/school needs
  2. Count backward - Allow 7-9 hours for sleep
  3. Wind-down buffer - 30 minutes to fall asleep
  4. Set bedtime - And stick to it

Pre-Sleep Routine

The Wind-Down Period

Duration: 30-60 minutes before bed

Recommended Activities

Activity Duration Benefits
Dim lights Throughout routine Signals melatonin production
Warm bath/shower 10-20 minutes Temperature drop after induces sleepiness
Light reading 15-30 minutes Mental relaxation (not on screen)
Gentle stretching 5-10 minutes Releases physical tension
Meditation/breathing 5-15 minutes Calms nervous system
Journaling 5-10 minutes Clears mind of worries

Creating Your Routine

Example Evening Routine:

9:00 PM - Dim lights, stop work
9:15 PM - Warm bath
9:30 PM - Light stretching
9:40 PM - Journal or read (paper book)
10:00 PM - Bed

What to Avoid Before Bed

Avoid Why
Screens Blue light suppresses melatonin
Intense exercise Increases alertness, body temperature
Heavy meals Digestion disrupts sleep
Stressful conversations Increases arousal
Work tasks Activates problem-solving mind
Thrilling content Exciting movies, games increase alertness

Daytime Habits

Light Exposure

Time Recommendation Purpose
Morning 15-30 minutes bright light Sets circadian clock
Daytime Natural light exposure Maintains alertness
Evening Reduce light exposure Prepares for sleep

Exercise

Timing Recommendation
Morning/afternoon Ideal time for vigorous exercise
Early evening Moderate exercise OK (finish by 7 PM)
Before bed Only gentle stretching or yoga

Benefits for sleep:

  • Increases sleep drive
  • Reduces stress and anxiety
  • Improves sleep quality
  • Helps regulate circadian rhythm

Napping

Guideline Recommendation
Duration 20-30 minutes maximum
Timing Before 3 PM
Frequency Occasional, not daily
If insomniac Avoid napping entirely

Caffeine

Timing Recommendation
Morning OK if needed
After noon Avoid or limit
After 2 PM No caffeine

Half-life: Caffeine has a half-life of 5-6 hours, meaning half is still in your system hours later.

Alcohol

Misconception Reality
"Helps me fall asleep" True, but fragments sleep later
"Relaxes me" Disrupts REM sleep, causes awakenings
"Better than nothing" Reduces sleep quality significantly

Things to Avoid

The "Don't" List

Avoid Reason Alternative
Clock-watching Increases anxiety Turn clock away from view
Screen time in bed Blue light, mental stimulation Read paper book instead
Staying in bed awake Weakens bed-sleep association Leave after 20 minutes
Weekend sleep-ins Disrupts circadian rhythm Maximum 1 hour variation
Late caffeine Stays in system hours Cutoff at noon
Alcohol before bed Fragments sleep Limit or avoid
Heavy meals late Digestion disrupts sleep Light snack if hungry
Intense exercise late Increases alertness Gentle stretching only
Worrying in bed Increases arousal Schedule worry time earlier

The 10-3-2-1 Rule

Hours Before Bed Avoid
10 hours Caffeine
3 hours Food and alcohol
2 hours Work
1 hour Screens
