What role does IgE play in Schlaf?

The provided context does not address the role of IgE in sleep. Generally, IgE (immunoglobulin E) is primarily involved in allergic responses. Elevated IgE levels can cause nighttime symptoms such as nasal congestion, coughing, or itching in allergic individuals, thereby impairing sleep quality. Studies link allergic rhinitis to sleep disturbances, but direct evidence for IgE's role in sleep regulation is weak. Some mechanistic research suggests that IgE-mediated inflammation may influence sleep-wake cycles via cytokines, but this remains speculative. Without relevant context, a conservative assessment is warranted. For personalized insights, IgE blood levels and a sleep history would be required.
