Dust Mite Allergy: How does it manifest itself?

Dust mite allergies, often underestimated, can prove to be very restrictive in daily life. The associated symptoms usually manifest during the night or upon waking, times when exposure is at its peak as dust mites proliferate in warm and humid places like mattresses. Among the most common symptoms of dust mite allergies, we find the allergic rhinitis which is characterised by persistent nasal congestion accompanied by frequent sneezing and itching. A blocked nose is often associated with an overproduction of mucus, which can cause some respiratory discomfort.

Dust mite allergies are not confined to the respiratory tract: they can also affect the eyes and cause a allergic conjunctivitis. The eyes can then become red, irritated, watery and ocular itching can occur throughout the day. In some individuals, an eczema-type rash may appear in the form of small red patches, accompanied by intense itching. This mainly affects individuals suffering from atopic dermatitis, who see their usual symptoms worsen in the presence of dust mites.

The symptoms of a dust mite allergy resemble those of a common cold, a pollen allergy, or an animal fur allergy. However, each of these different conditions has unique characteristics that allow them to be distinguished from one another.

In addition to antihistamines or corticosteroids frequently prescribed by doctors to alleviate dust mite allergies, certain simple actions can significantly reduce the presence of dust mites in a household, which are responsible for the symptoms. It is first necessary to take action within the bedroom, the favourite habitat of dust mites. It is recommended to opt for cotton sheets, covers and pillowcases as they can be washed weekly at 60°C, the necessary temperature to eliminate dust mites. The use of anti-dust mite covers is also advisable.

To prevent the accumulation of dust and mites, it may also be relevant to simplify the layout of the room by removing the objects that attract dust, such as thick curtains, carpets and rugs, and favouring blinds, wooden or tiled floors, which are easier to clean. It is also recommended to vacuum at least once a week, if possible with a HEPA filter, a high-efficiency air filter, and to dust surfaces and shelves each time with a damp cloth.

Finally, airing out the various rooms of the house for ten minutes each day can help slow down the proliferation of dust mites, as they prefer warm environments. Additionally, the use of a dehumidifier helps to keep the humidity level below 50%, a threshold that hinders the multiplication of dust mites. When combined, these various actions contribute to creating a less favourable environment for dust mites, and therefore less conducive to allergic reactions.
