You should wash your bed sheets as often as at least once a week.
Washing your bed sheets at least once a week, helps to maintain cleanliness and also minimize allergen exposure.
Some people who have allergies, pets or sweat at night may need to wash their bed sheets more frequently as in a few times a week or more.
It's a good idea to always change out your bed sheets at least once a week and have clean bed sheets available to replace them with, while your current bed sheets are being washed.
Blankets should also be washed at least once a week and the same is true with pillowcases.
I always change out my bed sheets a few times a week and my blankets as well unless they get something spilled on them or I'm sweating more often.
If I sweat more often then I wash the bed sheets after I've sweated and the same is true for the blankets.
Not washing your bed sheets regularly can lead to various health problems and discomforts, including skin issues, allergies, and the accumulation of dust mites.
Dirty bed sheets can also harbor bacteria, dead skin cells, sweat, and other debris, which can irritate the skin, exacerbate conditions like eczema, and contribute to acne breakouts.
Additionally, dust mites, which feed on dead skin cells which can be in and on bed sheets, can trigger allergic reactions and asthma flare-ups.
Married couples often change out their bed sheets every 19 days although some change their bed sheets more often.
