Frequently Asked Questions
Do cotton sheets actually help with allergies?
Yes — cotton itself doesn't reduce allergens, but breathable, tightly woven cotton and frequent washing reduce dust and trapped allergens compared with synthetic fabrics. Pairing cotton sheets with a zippered dust-mite mattress encasement and washable pillow protectors is the most effective approach for allergy control.
How can I keep a dorm bed cool at night?
Choose breathable natural fibers (100% cotton percale or sateen), avoid heavy blankets at night, keep bedding light-colored to reflect heat, and use a mattress protector designed for airflow. Also wash sheets regularly to remove sweat and oils that can trap heat.
How often should I wash sheets and protectors to reduce allergens?
Wash sheets and pillowcases weekly in warm or hot water if possible to reduce dust-mite allergens and body oils. Mattress encasements and pillow protectors can be washed less frequently (monthly or as needed) but should be spot-checked and laundered if you notice allergy symptoms or visible dirt.
