The answer to this question depends on many things but a straight response would be that you should change you bed sheets as often as possible. Because a fresh and hygienic bed is not only vital for wellness of your physical health but also for your mental health as good sleep and mental health are interconnected.

But on flip side, maintaining the bed and keeping everything clean and fresh is a time consuming job. More frequent replacement of bed sheet means more laundry and more time and effort required, that is why most people don’t change their bed sheets as often as they should.

Bed sheets can catch considerable amount of dust with in 3 to 4 Days or even earlier depending on many factors. In addition to dust, humans shed millions of dead skin cell that contaminate your sheets and besides that we can’t ignore the skin oil and sweating factor. All these things determine the time range in which you should change your bed sheet. Let’s discuss these factors in detail.

Dead Skin Cells

According to the American Academy of Dermatology (AAD), Humans shed between 30,000 and 40,000 skin cells every day and since we spend most time of our day on bed, most dead skin cells accumulate on our bed. These dead skin cells welcome other creatures like dust mites. These microscopic creature feed on our dead skin cells and they are not the only unpleasant thing found in bed sheet.

Body Oil

Under human skin there is a sebaceous gland that produces natural oils called sebum. This helps keep your skin hydrated and healthy but it can create a mess by combining with dust, dead skin cells, dust mites etc. Person with oily skin should change bed sheet more often than other people.


Some people sweat a lot at night and all this sweat mix up with body oils and dust and then bed sheet absorb this mixture. People who sweat more than normal should change their bed sheets every 4 to 5 days.

Do You Sleep Alone

If you share your bed with someone else or you have a pet that sleeps in bed with you then it’s obvious their dead skin cells,  body oils and sweat add up with your mess, making things more worse. In that case one should change bed sheet more frequently.
