The combination of sweat, saliva, dandruff, dead skin cells, and food particles provides an ideal environment for various germs to thrive, including bacteria, fungi, viruses, and tiny bugs. Humans shed around 500 million skin cells daily while sleeping in bed. These skin cells may attract and be consumed by microscopic dust mites. These mites and their droppings can potentially trigger allergies and asthma. Various microbial species can survive on fabrics for different periods. For instance, S. aureus can survive for a week on cotton and two weeks on terry cloth. Fungal species, like Candida albicans, which can cause oral thrush, urinary tract infections, and genital yeast infections, can survive on fabrics for up to a month. Influenza viruses can persist on fabrics and tissues for 8-12 hours. Certain viruses, such as the vaccinia virus, can survive on wool and cotton for up to 14 weeks.
