napallergia

Napallergia is a term used to describe an adverse immunologic reaction associated with the experience of napping or sleeping in a particular environment. It is not a formally recognized medical diagnosis in major classification systems, but it is sometimes discussed in patient reports and some allergy literature as a sleep-related allergen sensitivity.

Possible triggers are typically environmental and related to bedding and sleep conditions. Commonly implicated are airborne allergens that accumulate in bedding, such as dust mites in mattresses and pillows, animal dander, and mold spores. Contact allergens in pillow materials, fabrics, or laundry detergents and fabric softeners used on sheets can also play a role. Fragrances or additives in sleep products may contribute for some individuals.

Symptoms resemble other allergic conditions and may include nasal congestion, sneezing, itchy or watery eyes, coughing or wheeze, and skin reactions such as itching or hives. Some people report headaches or fatigue after naps, or symptoms begin soon after lying down. Severity varies and may be influenced by the degree of exposure and individual sensitivity.

Diagnosis is based on clinical history and, when appropriate, allergy testing. Tests such as skin prick or serum specific IgE can help identify sensitization to suspected triggers. Elimination or exposure challenges, and assessment of the sleep environment, are often used.

Management focuses on reducing exposure to identified triggers and optimizing the sleep setting. Measures include hypoallergenic bedding, frequent washing of bedding at high temperature, reducing humidity, using fragrance-free detergents, and maintaining a clean sleeping area. Pharmacologic treatment may involve antihistamines or intranasal corticosteroids; asthma therapies may be needed if respiratory symptoms occur. In selected cases, immunotherapy could be considered.
