Experts recommend washing your bed sheets once a week to remove sweat, body oils, dead skin cells, and other buildup that can harbor dust mites and allergens. While it may seem excessive, regularly laundering your bedding is important for better sleep and peace of mind.

Why it matters

Letting sheets go unwashed for too long can lead to the accumulation of bacteria, dust mites, and other allergens that can trigger health issues, especially for those with sensitive skin or asthma. Maintaining a weekly washing routine helps minimize these problems.

The details

Over time, sheets collect sweat, body oils, dead skin cells, and everyday dirt. Left unchecked, they can harbor dust mites and other allergens that thrive in warm, cozy environments. Sticking to a weekly washing routine helps minimize buildup and keeps your bed feeling and being clean.

  • The average person only washes or changes their bed sheets every 24 days, according to a survey.
