Since we spend about a third of our day sleeping, making sure your bedroom has minimal asthma triggers is of utmost importance. Here, we'll share environmental factors in your bedroom that can exacerbate asthma triggers. You've got hungry dust mites living there. “Airborne allergens are the most common asthma trigger, and the most common airborne allergen trigger is dust and and dust mites." says Cheryl Nickerson, registered respiratory therapist and certified asthma educator. Microscopic dust mites live in cloth surfaces, such as pillows, mattresses, and blankets that come in contact with our bodies. “They like these environments because they survive by feeding off dead flakes of skin that we shed and become trapped in our bedding," says Nickerson. After they eat our skin, their waste products and mite body parts trigger asthma symptoms. (Eww. Is anyone else scratching while reading this?) While these critters can be found anywhere in your home, they tend to be found in highest numbers in our bedrooms.
Your humidifier could be doing more harm than good. While you might think that running a humidifier will help you breathe better by adding moisture to dry air (particularly in the winter), for many people, a humidifier can contribute to asthma triggers, says Nickerson. While dry air can irritate eyes, skin, sinuses and the airways of lungs which can contribute to an increase in asthma and sinus symptoms, it's important to strike a balance in humidifying the air in our homes, she advises. “Overuse of humidifiers may result in growth of mold and mildew and promote dust mite infestation," she says.
