| Category |
Examples |

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