-In this Sleep Revolution study the aim was to give a better picture of what is happening in the upper respiratory tract when snoring occurs. The study consisted of two visits, both of which took place at Reykjavik University. For the first visit, participants were asked to be fasting for at least 1 hour before attending. In the second visit, where the installation of equipment before the night study took place, however, liquids were permitted less than 1 hour before the visit.+===== Dataset - General description =====

The data was collected from May - November 2021.

 The participant arrived at RU and slept there for one night in RU's Sleep Institute Sleep Lab under the supervision of a researcher to see if the equipment is measuring correctly. The participant was asked to arrive freshly bathed, with clean and dry hair. The participant was asked to fill out a short questionnaire on paper, in connection with the sleep study. The next day, the researcher assisted the participant to remove the equipment which concludes the study participation. The participant arrived at RU and slept there for one night in RU's Sleep Institute Sleep Lab under the supervision of a researcher to see if the equipment is measuring correctly.

 When the setup procedure was complete, the signals were checked. The researcher asked the participant to perform the same exercises as in visit 1, i.e. to imitate snoring and breathing pauses while they are awake. The participant was then asked to go to bed and sleep until the following morning. When the setup procedure was complete, the signals were checked.
