Is your pillow over two years old? Harvard doctor suggests throw it out. He also says discard two other things from bedroom

Many people often dismiss fatigue, mild fevers, or reduced stamina as temporary issues, but sometimes the cause lies closer to home than expected. According to Harvard-trained hepatologist and gastroenterologist Dr. Saurabh Sethi, the very space where one rests—the bedroom—may quietly undermine overall health. In a recent social media post, he drew attention to how certain common bedroom items can gradually erode sleep quality, disrupt gut health, and affect long-term wellness.

Why Bedroom Items Matter

Bedrooms are meant to be sanctuaries for rest and recovery. Yet, seemingly harmless objects within them can act as slow but steady contributors to physical discomfort and illness. Dr. Sethi identified three household items that deserve immediate attention. By eliminating or replacing them, individuals can significantly improve their sleep, breathing, posture, and general well-being.

Outdated Pillows—A Hidden Source of Allergens

Pillows, though often overlooked, can become problematic when used beyond their recommended life span of one to two years. Over time, they accumulate dust mites, sweat, bacteria, and allergens that are invisible to the eye but harmful to the body. Prolonged exposure may worsen sinus issues, aggravate allergies, and even cause skin irritation. Additionally, worn pillows lose their support structure, which interferes with sleep quality and neck comfort. Simply replacing pillows at regular intervals can reduce these risks and help restore restful sleep.

The doctor cautioned, "If your pillows are over one to two years old, it's time to replace it."

Synthetic Air Fresheners—A Chemical Trap

Air fresheners are widely marketed as quick fixes for unpleasant odors, but many synthetic varieties conceal health risks. Dr. Sethi cautions that these products often release phthalates and volatile organic compounds (VOCs), both of which have been associated with hormonal disturbances, respiratory irritation, and even reproductive health concerns. Research from the Natural Resources Defense Council in 2007 revealed that a striking 86 percent of tested air fresheners contained phthalates, including some products labeled as “natural” or “unscented.”

Since phthalates are commonly used in plastics, perfumes, and aerosols, frequent exposure can increase the likelihood of asthma and other long-term health problems. Instead of relying on chemical-based sprays, Dr. Sethi recommends switching to natural alternatives like essential oils or organic diffusers that freshen the air without harmful side effects.

Old Mattresses—Comfort Turned Hazard

Mattresses are another overlooked contributor to health decline. Many people hold on to their mattresses far longer than advisable, often beyond a decade. However, mattresses generally lose their structural support after seven to ten years. A worn-out mattress can cause poor spinal alignment, resulting in chronic back or neck pain and restless sleep. In the long run, this compromises posture and makes it harder for the body to recover overnight. Upgrading to a supportive mattress not only improves comfort but also prevents long-term musculoskeletal problems.

Small Changes, Big Impact

Though old pillows, artificial air fresheners, and aged mattresses may not seem threatening, they quietly impact health over time. Dr. Sethi highlights that making simple adjustments—such as refreshing pillows, opting for natural room scents, and investing in a new mattress—can dramatically improve sleep, boost energy, and protect long-term wellness. The key takeaway is clear: a healthier body often begins with a healthier bedroom.

Who Is Saurabh Sethi?

Dr. Saurabh Sethi is a gastroenterology specialist practicing in California. With advanced medical education from AIIMS, along with further academic and clinical training at Harvard and Stanford, he brings over twenty years of expertise to his field. Over the course of his career, he has crafted a unique framework for nutrition and lifestyle that blends rigorous scientific principles with a nuanced understanding of holistic traditions. His approach stands at the crossroads of modern medical research, sustainable living practices, and long-term health success.

Central to his philosophy is the recognition that digestive health forms the foundation of overall vitality. Dr. Sethi underscores how the condition of the gut directly influences multiple dimensions of life, ranging from physical energy and immunity to mental clarity and emotional balance. He points out that the gut microbiome—the community of microorganisms residing in the digestive system—plays a crucial role in shaping how the body and mind function. By nurturing this internal ecosystem, individuals can experience improvements that extend far beyond digestion, ultimately enhancing both daily performance and long-term well-being.
