Overview
- This week, Argentine outlets shifted public guidance from a strict weekly-sheet rule to focusing on how sheets are washed as the key factor for mite control.
- A 2008 lab study cited across reports found about 6.5% mite mortality at 30 °C, about 9.6% at 40 °C, and complete elimination at 60 °C or with the steam protocol used in the experiment.
- Experts warn that those experimental results depend on specific conditions and that many fabrics and home machines are labeled against frequent 60 °C washes, so consumers must check care instructions before using high heat.
- Practical laundry advice paired with the hygiene message includes separating fabrics, using the correct detergent dose, avoiding excess fabric softener that leaves residues, and fully drying and storing sheets to preserve softness and lifespan.
- For people with allergies, regular washing with the hottest safe option for the fabric will reduce allergen load more than simply airing the bed, since airing helps dissipate moisture but does not reliably remove mites from mattresses and pillows.
