Old or low-quality mattresses and pillows
Many mattresses and pillows made with synthetic foams release volatile organic compounds (VOCs), such as formaldehyde or toluene, linked to respiratory irritation and long-term carcinogenic effects.
What to do: Choose mattresses certified as toxin-free and covers made from natural cotton or bamboo.

Particleboard or MDF furniture
These materials often contain formaldehyde, an invisible gas used as an adhesive that is slowly released into the air. Prolonged exposure can irritate the eyes, skin, and respiratory tract, and has been associated with nasopharyngeal cancer.
What to do: Keep your room well-ventilated, seal furniture with natural coatings, or replace them with solid wood pieces.

Scented candles and synthetic air fresheners
When burned, paraffin candles and aerosol sprays release benzene and toluene—substances recognized by the WHO as carcinogenic.
What to do: Use beeswax or natural soy candles, and choose diffusers with pure essential oils.

Curtains, carpets, or upholstery with chemical treatments
Many household fabrics are treated with flame retardants or PFAS (per- and polyfluoroalkyl substances), persistent chemicals that can disrupt hormones and increase cancer risk.
What to do: Opt for natural fabrics (cotton, linen, wool) without synthetic treatments, and wash them regularly.

TV, Wi-Fi router, or chargers near the bed
Constant exposure to electromagnetic fields may disrupt circadian rhythms. Although evidence on carcinogenic effects is still being studied, experts recommend limiting exposure while sleeping.
What to do: Unplug devices or keep them at least two meters away from your bed.

Old paints and varnishes
Paints containing lead or old solvents can release gases and heavy metals that become toxic over time.
What to do: If you plan to repaint, use eco-friendly water-based paints and ensure proper ventilation.

Dirty clothes or clutter buildup
While not toxic by themselves, accumulated dust, sweat, and humidity encourage mold and bacteria growth, which can affect your lungs and immune system.
What to do: Keep your room clean and dry, and avoid leaving damp clothes or unventilated rugs.

How to Promote Health and Better Sleep

• Air out your room every day for at least 15 minutes to renew the air and remove accumulated gases.

• Use natural materials for bedding and furniture.

• Avoid excessive electronic devices near your bed.

• Adjust lighting: use warm lights and avoid screens before sleep.

• Keep visual order: a clean, uncluttered space helps your body relax.

Your bedroom can either be a sanctuary of well-being or a silent source of pollution. Objects that seem harmless may release harmful substances each night without you realizing it.

Transforming that space doesn’t require luxury—just awareness and small changes: clean air, natural materials, and an environment free of stress and chemicals.
Sleeping in a healthy environment not only improves your rest but also protects your long-term health.
