Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It has been demonstrated that allergic rhinitis (AR) reduces sleep quality by some components such as nasal obstruction. Pollution and allergen exposure worsening AR, sleep quality is deteriorated.

Sleep is associated to physical and mental health, alterations in sleep could explain the link between AR and work productivity diminution, impairment in daily activities or emotional problems.

However, interactions between air pollution, sleep and allergic diseases are insufficiently understood.

The main objective of this study is to determine the impact of pollution and pollens on sleep parameters.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Over 150 million people have allergic rhinitis (AR) in Europe and around 30% have uncontrolled AR during allergen exposure. It has been demonstrated that AR reduces sleep quality by some components such as nasal obstruction. Pollution and allergen exposure worsening AR, sleep quality is deteriorated.

Sleep is associated to physical and mental health, alterations in sleep could explain the link between AR and work productivity diminution, impairment in daily activities or emotional problems.

However, interactions between air pollution, sleep and allergic diseases are insufficiently understood.

Moreover, the prevalence of OSA in patients with AR is higher than in subjects without AR. Nasal obstruction could explain the increased risk of OSA.

This prospective, open study will compare sleep quality in 2 different groups: AR patients and patients without AR during the pollen season and outside the pollen season.The main objective is to determine the impact of pollution and pollens on sleep parameters for subjects with AR
