Bedroom Air Quality Checklist for Better Sleep

We spend one-third of our lives in our bedrooms, yet they often have the worst air quality in the house. Closed doors, dust mites in bedding, and CO2 buildup from breathing all night create a "stale air cocktail" that ruins sleep quality. Use this checklist to transform your bedroom into a recovery zone.

1. The Pre-Sleep Flush

CO2 levels peak around 3 AM in closed bedrooms, leading to grogginess. Fix this before you even get into bed.

• Action: Open windows wide for 5–10 minutes before turning out the lights.
• Why: This replaces stale, humid air with fresh, oxygen-rich air without chilling the walls/furniture too much.
• Alternative: If it's too cold or polluted outside, run an air purifier on "High" for 30 minutes before bed, then switch to "Sleep Mode".

2. Humidity Control (The Goldilocks Zone)

Your throat and sinuses need moisture, but dust mites love it too.

• Target: 40% to 60% Relative Humidity.
• Too Low (<30%): Dry throat, snoring, and vulnerable mucous membranes. Use a clean humidifier.
• Too High (>60%): Mold risk and dust mite explosion. Use a dehumidifier or improve ventilation.

3. Dust Mite Management

You are sharing your bed with millions of microscopic creatures. Sorry, but it's true.

• Bedding: Wash sheets weekly in hot water (60°C/140°F). Cold water cleans dirt but does not kill mites.
• Covers: Use allergen-proof encasements for mattresses and pillows. They weave is too tight for mites to pass through.
• Pillows: Replace pillows every 1-2 years, or wash them if they are synthetic. Old pillows are heavy with dead skin and mite waste.

4. Reduce "Stuff"

Clutter gathers dust. The fewer items on your nightstand and floor, the cleaner the air.

• Books: Old books can be dusty and moldy. Keep libraries in the living room, not near your head.
• Under the Bed: Keep this area clear. Storing boxes here blocks airflow and creates a dust bunny farm you can't easily clean.
• Pets: Ideally, keep pets out of the bedroom. If they must sleep there, give them their own bed (washed weekly) rather than sharing yours.

5. Filtration Strategy

Your body repairs itself during sleep. Give it clean air to do the job.

• Placement: Put the air purifier about 1-2 meters from your head, but not blowing directly on your face (which can dry out sinuses).
• Lights: Tape over bright LEDs on the purifier. Darkness is as important as air quality for melatonin production.

Summary

Better air means deeper sleep and clearer mornings. Start with the "Pre-Sleep Flush" tonight—it costs nothing and works immediately.
