While some patients improve over time, many experience long-lasting complaints. Health resort treatment has shown potential benefits in long COVID, but its effects on sleep and quality of life remain unclear. This study aimed to evaluate the impact of comprehensive health resort treatment on insomnia and quality of life in post-COVID-19 individuals and to compare outcomes with those without prior SARS-CoV-2 infection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 101 participants, including 30 post-COVID-19 individuals, underwent comprehensive health resort treatment. Propensity score matching was used to compare post-COVID-19 and non-COVID groups. Insomnia and health-related quality of life were assessed using the Athens Insomnia Scale and EQ-5D-5L, respectively, before and after the sanatorium stay.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The Athens Insomnia Score significantly decreased in post-COVID-19 individuals following sanatorium treatment (6.24 \u00b1 5.93 vs. 3.97 \u00b1 4.19 points;\n                      <jats:italic>p<\/jats:italic>\n                      = 0.0005).
