Actual (reported)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.

Actual (reported)Impact of pollution on sleep
Change in AHI according to the level of pollution particle matters and volatile organic compounds (VOCs)
6 days
The impact of pollution and pollens on sleep quality in patients with AR.
6 days
The impact of pollution on life quality
6 days
Patients with AR and obstructive sleep apnea (OSA) will have sleep and pollution exposure recordings
Patients without allergic rhinitis (+ sleep apnea) will have sleep and pollution exposure recordings
Patients with allergic rhinitis but no sleep apnea will have sleep and pollution exposure recordings
Pollution exposure and sleep data will be recorded by pollution sensor and polysomnography respectively. In order to compare the variations according to the pollinisation season and the allergic rhinitis status of the patients.
