Scientists: When Should You Change Your Bed-sheets?

Good sleep can help your body recover from the stress of work and other daily activities. Bedtime is one of the most anticipated events of the day. This is true especially for people who work very hard. A short survey has however shown that our beds where we spend so much time may become a source of health issues if the sheets are not regularly washed.

In his study, Philip Tierno, a Microbiologist at the New York University stated that dirty bed sheets could promote the multiplication of different types of bacteria. The ‘invasion’ of bacteria in your bed space can also happen very quickly while the people will not notice what is happening until it is too late.

Our beddings comprise bed sheets, pillows, and duvets which can provide the right environment for microscopic organisms to thrive. If this goes unnoticed for a long time, the users could face some health issues. In his recommendation, Philip suggests that bed sheets should be replaced and washed at least once a week.

People who are prone to experiencing reactions due to allergens should also take note of this information. There have been several research studies that find the presence of multiple forms of allergens in bed sheets and other linen used as beddings. The research covered hundreds of American homes where the results indicated a repeated trend that confirmed the existence of these allergens in the bed sheets.

Consequently, they trigger reactions such as sneezing and in some cases breathing difficulties. This happens especially when the allergens get into our bodies through the nose or mouth while we sleep. Everyone can have an allergic response even without prior indications of being allergic. Thus no one is entirely protected when sleeping on dirty bed sheets that have become infested with these micro allergens. It is, therefore, necessary to keep the bed sheets clean by frequently washing and proper drying.

During the warmer seasons, moisture from sweat while we sleep during the day or night can promote the growth of micro-organisms on the bed sheets. Sweating is normal and happens even under cool temperature in some cases. It is quite difficult to avoid sweating because we cannot influence our internal body functions. However, what can be done is to prevent the conditions that promote the growth of fungus on our bed sheets.

Asides from the moisture caused by our sweat, fungus, and bacteria can also be introduced on the bed sheets from drooling saliva while sleeping. Other sources include body fluids during sex and dirt from pets if they are allowed on the bed.

The deposits from these sources can seem very little but over time (few weeks) it will be significant. The microbiologist, Philip Tierno, suggests that we can increase our ‘defense’ against harmful bacteria and fungus in many ways. Top of the list includes regularly washing our hands, keeping the pets clean and having regular baths. If we can maintain proper personal hygiene while washing bed sheets regularly, we can reduce the tendency of bacteria to overrun our beddings.
