You should wash your sheets about once a week to maintain cleanliness and a healthy sleep environment. This frequency is widely recommended by medical experts and sleep specialists because sheets accumulate sweat, dead skin cells, body oils, dust mites, and bacteria, which can affect hygiene and sleep quality
. If you use a top sheet, some suggest you can extend washing to once every two weeks, but weekly washing is ideal especially if you sweat a lot, have allergies, asthma, sensitive skin, or allow pets in bed
. During hotter months or if you tend to sweat more, washing more frequently is beneficial
. In summary:
- Once a week is the standard recommendation.
- Every two weeks may be acceptable if you use a top sheet and have no special conditions.
- Wash more often if you sweat heavily, have allergies, or pets share your bed.
This routine helps prevent buildup of sweat, dead skin cells, mites, and bacteria that can cause discomfort, skin irritation, or allergic reactions
. Additionally, washing sheets in warm or hot water (as per care labels) and drying them thoroughly helps ensure they are hygienic and last longer
. Thus, aiming for weekly sheet washing is best practice for health and comfort.
