Introduction: Why I woke up exhausted every morning

For 5 years, I struggled with insomnia. Waking up at 3 a.m., unable to go back to sleep, foggy days. I tried everything: melatonin, valerian, magnesium, meditation, sleep apps…

Nothing worked sustainably.

My doctor spoke of stress. My ruminations therapist. I felt guilty about not being able to “let go”.

Then I moved.

First miracle: I slept better in my new empty apartment than in my old, super comfortable room. Weird.

Second miracle: when I rearranged my room identically (same mattress, same sheets, same bedding), insomnia returned.

I ended up understanding: it wasn’t my bed that was the problem. That was all there was around.

The old room was saturated with VOCs (chipboard furniture), dust mites (carpet), scented detergent residue, and accumulated dust. My nervous system spent the night fighting against irritants instead of resting.

Today, after 2 years in a “sanctuary room”, I sleep 7 hours straight. Sans aucun complément. Here’s how I did it.

The science of sleep and the environment

Why your bedroom impacts your sleep

During sleep, your body is particularly vulnerable:

Slowed but deep breathing: you inhale the air from your room for 8 hours

Relaxed skin barrier: chemical substances penetrate more easily

Nervous system in repair mode: irritants disrupt this process

What the research says

A study from Environmental Health Perspectives (2019) analyzed the air quality in 1,000 bedrooms. Results:

Rooms with polluted air = 40% more sleep disorders

VOCs (formaldehyde, benzene) disrupt deep sleep cycles

Dust mites linked to a 60% increase in nighttime awakenings

According to the OQAI (Indoor Air Quality Observatory):

The air in bedrooms is often 3 to 5 times more polluted than the living room

Main cause: insufficient ventilation + accumulation of dust/allergens

The 10 actions for a bedroom conducive to sleep

1. Make your bedding a chemistry-free zone

The problem: You spend 8 hours with your nose on your pillow. If your laundry detergent is scented, you’re inhaling phthalates all night long. If your sheets have detergent residue, your skin is continually irritated.

Solutions:

Fragrance-free laundry detergent (really without – check the composition)

Double rinsing systematic

White vinegar as a softener (no traditional softener)

Wash at 60°C minimum (kills dust mites)

My protocol: I wash my sheets every week with organic fragrance-free detergent + 1 glass of white vinegar + 2 rinse cycles. My sheets smell… nothing. And it’s perfect.

—

2. Treat the mattress and pillows naturally

The issue: An untreated mattress contains on average 2 million dust mites after 2 years of use. Their droppings are highly allergenic and disrupt sleep.

Monthly protocol:
1. Vacuum the mattress (HEPA vacuum cleaner)
2. Sprinkle with baking soda
3. Leave to act for 2-4 hours
4. Vacuum again

Quarterly: Steam cleaning (100°C kills mites instantly)

Pillows: Machine washable every 3 months at 60°C, or annual replacement

Recommended investment: Certified anti-mite covers for mattresses and pillows (cotton, not plastic)

—

3. Dust smartly

The classic mistake: The traditional duster does not capture dust, it disperses it into the air. You “clean”…and breathe in the particles all night.

The right method:

Wet microfiber: Captures dust without dispersing it

Clean from top to bottom (dust falls)

Insist on: headboard, bedside tables, lamps, frames

Frequency: Minimum 2 times per week. Ideally in the morning, so that the dust raised is evacuated before bedtime.

My favorite tool: The H2O at Home microfiber catches everything without any chemical dusting spray. A slightly damp microfiber and that’s it.

—

4. Ventilate strategically

The golden rule: 15-20 minutes of ventilation morning AND evening. Yes, even in winter.

Why it’s crucial:

Evacuates CO2 accumulated during the night

Dilutes VOCs emitted by furniture

Reduces humidity (enemy of sleep)

Renews oxygen

Optimal protocol:

Morning: Open wide as soon as you wake up, leave the bed open (wicks away humidity)

Evening: Air out 15 minutes before bedtime, then close

Create a draft: Opposite windows if possible

In summer: Ventilate early in the morning and late in the evening (fresher air)

—

5. Eliminate sources of VOC

VOCs (Volatile Organic Compounds) are gases emitted by many everyday objects. They irritate the respiratory tract and disrupt deep sleep.

Main sources in the room:

Chipboard/MDF (formaldehyde) furniture

Recent paintings (< 1 year)

Synthetic carpets and rugs

Scented candles

Home fragrances

Actions:

Prefer solid wood or second-hand furniture (VOCs already evacuated)

Ban scented candles and air fresheners

If new furniture: ventilate intensively for 3-6 months

Avoid cleaning with chemical sprays in the bedroom

—

6. Clean the floor without chemicals

The problem: Detergent residue on the floor emits VOCs and attracts dust. You walk on it barefoot, then you go to bed…

My method:
1. Aspire (HEPA): 2x/week
2. Wash: Damp microfiber + water only

The perfect tool: The H2O at Home microfiber mop cleans effectively without any product. The floor is clean, without chemical residue, and dries in a few minutes.

Ideal floor for the bedroom: Parquet or smooth linoleum (easy to clean, no dust nest like carpet)

—

7. Choose an optimal temperature

The science of sleep: The body needs to cool down to fall asleep. A room that is too hot disrupts this mechanism.

Ideal temperature: 16-19°C

Why it’s good for bedroom health too:

Mites love heat (> 20°C)

Hot air retains more humidity

VOCs evaporate faster at high temperatures

If you are cold: Warm duvet + cool bedroom, rather than warm bedroom + light duvet

—

8. Manage humidity

The delicate balance: Too humid = mold and mites. Too dry = respiratory tract irritation.

Objective: 40-50% relative humidity

Measure: Invest in a hygrometer (€10-20)

Natural solutions:

If too humid: Ventilate more, natural absorbers (activated carbon, coarse salt)

If too dry: Bowl of water on the radiator, green plants

Drying clothes: NEVER in the bedroom (increases humidity by 30%)

—

9. Create a minimalist environment

The disorder-sleep link: Studies show that visual disorder stimulates the visual cortex and increases the level of cortisol (stress hormone). Not ideal for falling asleep.

Actions:

Reduce objects on surfaces

Closed storage (cabinets, chests of drawers) rather than open shelves

No desk/work in the room if possible

Minimal textiles (fewer surfaces to dust)

Health bonus: Fewer objects = less dust = fewer allergens

—

10. Establish a Calming Cleaning Routine

The paradox: Cleaning with chemicals before sleeping is counterproductive. The VOCs emitted disrupt sleep.

My evening routine (5 min):
1. Put away the day’s clothes
2. Pass the damp microfiber over the surfaces (without spray)
3. Ventilate for 10 min during this time
4. Close window, turn off screens

My weekly routine:

Monday: Floor vacuuming

Wednesday: Surface dust (microfiber)

Saturday: Change of sheets + washing

FAQ: Sleep and bedroom environment

Window light bedroom — Bedroom light window

Can I use essential oils to sleep better?

With caution. Lavender or chamomile EOs can help some people, but they emit natural VOCs. If you are sensitive (allergy, asthma), avoid diffusion. Alternative: a few drops on a tissue away from the bed.

Is carpet incompatible with good sleep?

She complicates things. Carpet accumulates dust, mites and allergens in its fibers. The ideal is a smooth floor. If you can’t change, vacuum 3x/week (HEPA) and do professional cleaning annually.

How long does it take to see improvement in sleep?

Most people notice a difference within 1-2 weeks after sanitizing their room. The VOCs take a few days to dissipate, and the body gradually recovers.

Should you change your mattress?

Not necessarily. Regular treatment (bicarbonate + vacuuming + steam) can extend the life of a mattress. But if your mattress is more than 10 years old or you wake up with a stuffy nose, the change may be beneficial.

Are plants in the bedroom good or bad?

Neutral to slightly positive. The myth “plants steal oxygen at night” is false (negligible amount). Certain plants slightly depollute the air (spathiphyllum, pothos). Just avoid fragrant flowering plants if you are sensitive.

How do I know if my room is polluted?

Telling signs: waking up with a stuffy nose, headaches upon waking up, dry throat, fatigue despite a full night’s sleep. You can also invest in an air quality sensor (VOC, CO2) to measure objectively.

Conclusion: Your bedroom, your sleep sanctuary

Insomnia is not always in your head. Sometimes it is in your environment.

What my 5 years of struggle taught me:

The air in your room directly impacts your sleep

Household products can be invisible disruptors

A healthy bedroom can be created with simple actions

My advice? Start with three changes this week:
1. Ventilate for 15 minutes morning and evening
2. Treat your mattress with bicarbonate
3. Clean surfaces with a damp H2O at Home microfiber (without spray)

These actions eliminate 70% of nighttime irritants. They cost almost nothing. And they can transform your nights.

Make your bedroom a true sanctuary.
