ABSTRACT=<sec id="sec1"><title>Background</title><p>Vitamin D, essential hormone for endocrine, autocrine, and paracrine functions. A billion people are deficient globally which contributing to numerous health issues. This study explores the link between vitamin D levels and sleep quality, impacting mental and physical health in adults.</p></sec><sec id="sec2"><title>Methods</title><p>This prospective cross-sectional study was conducted at Nims Hospital, Jaipur, involving 484 adults’ participants. Blood samples were collected for serum 25(OH) D measurements. Data were gathered using the SF-36 and ISI questionnaires to assess health and sleep quality.</p></sec><sec id="sec3"><title>Results</title><p>Higher vitamin D levels were strongly linked to better physical health, including physical function (<italic>r</italic> = 0.642, <italic>p</italic> &lt; 0.001), general health (<italic>r</italic> = 0.560, <italic>p</italic> &lt; 0.001), and PCS score (<italic>r</italic> = 0.441, <italic>p</italic> &lt; 0.001). Vitamin D also positively impacted social functioning (<italic>r</italic> = 0.096, <italic>p</italic> = 0.035) and was negatively related to ISI scores (<italic>r</italic> = −0.112, <italic>p</italic> = 0.014).</p></sec><sec id="sec4"><title>Conclusion</title><p>The study highlights a strong link between higher vitamin D levels and improved physical and mental health, with significant negative correlation to ISI scores. This underscores the importance of adequate vitamin D for overall well-being. The findings call for urgent measures to address vitamin D deficiency and further research into its health impacts.</p></sec>
