Many people wake up with irritated skin or feel a stuffy nose when the alarm clock rings. You probably don't think about it, but it could also be the fault of the sheets, which, when not clean, are able to attract a lot of allergens. Not only that, dust from the atmosphere also settles on the sheets and is inhaled for about eight hours a day.
Moreover, the list of what lurks in the bed makes quite an impression: fungi, bacteria, animal hair, pollen, but also various residues of the human body, such as sweat, sputum, vaginal and anal secretions, urine, skin cells. According to various researchers, even the quantities are frightening: it has been calculated that an average-sized man can release up to 100 litres of sweat a year into his bed and that pillows, whether feather or synthetic, can contain between 4 and 17 different species of fungi. In addition, there are residues from food that sometimes happens to be consumed in the bed, and from cosmetics, such as oils and body creams.
Beds are also the favourite nest of mites, which find a moist environment here, perfect for their survival. There can be 12,000 of them per gram of dust and up to a million in the mattress. These small insects can aggravate asthma, exacerbate or cause allergies such as rhinitis and hives.
