Microbiologist warns of serious lung infections from not washing sheets

Washing sheets regularly is essential for maintaining a good hygiene routine and reducing the risk of respiratory illnesses, as these pieces of fabric have the ability to accumulate sweat, dead skin cells, body oils, and dust mites.

In this sense, changing bedding is crucial to prevent allergies, irritations, and even unpleasant odors, which is why some people replace these items at least once a week.

In contrast, Primrose Freestone, a senior lecturer in clinical microbiology at the University of Leicester, UK, says that humans typically lose hundreds of cells overnight.

The academic also maintains that during the sleep cycle, the body secretes oils from the sebaceous glands, so up to half a liter of sweat can be produced without people realizing it.

Furthermore, in one of the articles she published on the digital media outlet 'The Conversation,' the microbiologist stated that human skin harbors many fungi and bacteria that accumulate on sheets and pillows.

According to the professor, the fresh sweat released during nighttime movement is the main cause of body odor, although some people shower before bed.

According to Freestone, mites themselves are not dangerous, but their fecal matter is an allergen , increasing the risk of worsening conditions such as dermatitis, asthma, or allergic rhinitis.

Another factor to consider is the proliferation of Aspergillus fumigatus , a fungus that can lodge in pillows and is responsible for causing serious lung infections, especially if people do not have a strong immune system.

In light of this, the expert believes it's important to pay attention to certain signs that can help prevent some conditions related to poor washing of sheets or comforters.

Based on this, the microbiologist recommends seeking professional help if symptoms are persistent and last more than three weeks , as this may mean you have a serious lung condition.
