Harvard gastroenterologist urges people to throw away THESE 3 toxic bedroom items ASAP

For most people, their bedroom is considered the safest place-- where one can simply be comfortable and themselves. However, did you know that you could be keeping some everyday items in your bedroom that are highly toxic. So much so that they may be secretly harming your health-- from affecting your respiratory health to your sleep-- if ignored for long.

On June 14, Dr. Saurabh Sethi, MD, MPH— a board-certified gastroenterologist, hepatologist, and interventional endoscopist trained at AIIMS, Harvard, and Stanford— shared an important reminder on Instagram. In his post, Dr. Sethi highlighted three common household items that could negatively affect gut health, sleep quality, and overall well-being if not replaced or used with caution.

"Did you know your bedroom might be silently affecting your gut, sleep, and long-term health? In this eye-opening video, Harvard and Stanford-trained doctor Dr. Sethi breaks down 3 common items found in most bedrooms that you should throw out ASAP," his post read.

Here are the 3 things toxic bedroom items he pointed out and urged people to throw away for better health:

1. Old pillows
Pillows may look harmless, but over time they become breeding grounds for dust mites, allergens, and bacteria. According to Dr. Sethi, if your pillow is older than one to two years, it could be interfering with both your sleep and respiratory health. Dust buildup can worsen allergies, trigger sinus problems, and even affect skin health. Replacing pillows regularly can help improve sleep quality and reduce exposure to irritants.

2. Synthetic air fresheners
While air fresheners are often marketed as a quick way to make rooms smell fresh, many synthetic versions release chemicals that can be harmful. Dr. Sethi explained that these products often emit phthalates and volatile organic compounds (VOCs), which have been linked to hormonal disruption, respiratory problems, and even reproductive health issues.

Supporting this claim, a study by the Natural Resources Defense Council (NRDC) in 2007 found that 86 percent of air fresheners tested contained phthalates, including some that were labeled “unscented” or “all-natural.” Phthalates are commonly used in plastics, perfumes, sealants, and aerosols, and long-term exposure may increase the risk of asthma and other health concerns. Dr. Sethi recommends natural alternatives, such as essential oils, instead of synthetic sprays.

3. Worn-out mattresses
Did you know that mattresses don’t last forever, and holding onto one for too long may cause more harm than comfort? Yes, you read that right! Dr. Sethi suggests that mattresses older than 7 to 10 years can compromise sleep quality and contribute to chronic back or neck pain. An old mattress can lose its structure, leading to poor spinal alignment, which in turn affects long-term posture and overall rest.

Why this matters
While none of these items may seem immediately dangerous, Dr. Sethi emphasises that they can silently affect health over time. Simple changes— like replacing pillows, switching to natural room fresheners, and investing in a good mattress— can make a noticeable difference in improving both sleep and overall well-being.

For many, the bedroom is where rest and recovery happen. Making it a healthier space might just be one of the simplest ways to support better long-term health.
