The participants completed a semistructured interview, filled in questionnaires about quality of sleep (PSQI), daytime sleepiness (ESS), depression (SDS) and anxiety (SAS) and they kept a 90-day headache and sleep diary.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Seventy-six snorers (25 female) and 41 bed partners (31 female) completed the study recording a total of 6690 and 3497 diary days, respectively. NH were recorded on 222 (3.3%) and 79 (2.2%) days in 32 (42%) snorers and 17 (41%) bed partners, respectively. Snorers with NH showed significantly higher PSQI (5\u2009\u00b1\u20093 vs. 4\u2009\u00b1\u20092, p\u2009=\u20090.004), SAS (38\u2009\u00b1\u200911 vs. 31\u2009\u00b1\u200910, p\u2009=\u20090.011) and SDS scores (39\u2009\u00b1\u200912 vs. 34\u2009\u00b1\u200910, p\u2009=\u20090.048) than snorers without NH. For bed partners with NH we found a significant female predominance (sex ratio f:m\u2009=\u200916:1 vs. 12:12, p\u2009=\u20090.005) and significantly higher SAS scores (38\u2009\u00b1\u20096 vs. 33\u2009\u00b1\u20098, p\u2009=\u20090.030) compared with bed partners without NH. The subjective quality of sleep in habitual snorers ( p\u2009&lt;\u20090.001) as well as their bed partners ( p\u2009=\u20090.017) was negatively influenced by NH, but not total sleep time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>NH occurred in around 40% of snorers and their bed partners at least once during the 90-day observation period.
