Your bedroom may feel like the safest and most comfortable place in your home, but according to Harvard-trained gastroenterologist Dr Saurabh Sethi, it could be hiding health hazards you don’t even think about.

Dr Sethi, MD, MPH, is board-certified in gastroenterology, hepatology, and interventional endoscopy, trained at AIIMS, Harvard and Stanford. In a recent video, he cautioned against three surprisingly common bedroom items that may be silently harming your health and even disrupting your sleep. “3 toxic bedroom items you should throw out ASAP,” Dr Sethi said, before listing them out one by one. “1. Old pillows. Pillows accumulate dust mites, sweat, and allergens over time. If yours is over 1-2 years old, it is probably time to replace it. 2. Synthetic air fresheners. Many of these release phthalates and VOCs linked to respiratory issues and hormonal disruption. In one of the studies, 86% of air fresheners tested contained phthalates, which are chemicals associated with reproductive harm and asthma. Try essential oils instead. 3. Worn-out mattresses. A mattress that is more than 7-10 years old can lower sleep quality and cause chronic back pain.”
To dig deeper, we spoke with an expert.
Why you should replace your pillow
Dr Palleti Siva Karthik Reddy, consultant physician at Koshys Hospitals, tells indianexpress.com, “The primary health risk from old pillows is prolonged exposure to allergens, which drives chronic inflammation. The house dust mite, Dermatophagoides pteronyssinus, and its foecal matter are the main sources of the potent allergen Der p 1. When inhaled, this enzyme triggers an IgE-mediated Type I hypersensitivity reaction, leading to conditions like allergic rhinitis and asthma.”
Beyond mites, he says, research highlights a significant fungal risk. “A notable study led by Woodcock et al. and published in the journal Allergy (2005) analysed pillows that had been in use for 1.5 to 20 years. They identified thousands of fungal spores per gram of used pillow, with Aspergillus fumigatus being a particularly common and hazardous species. This constant, low-level exposure to fungal and mite allergens can make individuals more susceptible to respiratory infections and severe allergic reactions.”
Air fresheners are documented emitters of toxic chemicals
Synthetic air fresheners release a complex mixture of chemicals, many of which are undisclosed on product labels. Dr Reddy states, “A seminal study by Steinemann (2011) published in Environmental Health Perspectives analysed 25 common fragranced products, including air fresheners. The research found that these products emitted over 133 different Volatile Organic Compounds (VOCs). On average, each product emitted 17 VOCs, with nearly a quarter of these classified as toxic or hazardous under U.S. federal laws, including known carcinogens like benzene and formaldehyde. Critically, these chemicals were not listed on the product labels.
One of the most concerning classes of these chemicals is phthalates, which act as endocrine disruptors. Research, such as the review by Kelley et al. in Current Problems in Pediatric and Adolescent Health Care (2012), details how phthalates can interfere with androgenic pathways, linking exposure to adverse reproductive and neurodevelopmental outcomes.”
Red flags that a mattress has become harmful
The link between mattress quality and musculoskeletal health is well-established in clinical research. Dr Reddy mentions, “A mattress loses its ability to provide uniform support over time, leading to sagging and a failure to maintain neutral spinal alignment. This forces the spine into flexion or extension for prolonged periods, placing significant stress on intervertebral discs, facet joints, and paraspinal muscles, contributing to chronic low-back pain.”

Visible sagging and waking with pain are not just signs of discomfort but are clinical indicators that your mattress is no longer a therapeutic surface and may be actively contributing to musculoskeletal pathology.
