Rationale: Sleep deprivation leads to non-communicable diseases and metabolic disorders that decrease life quality. This study examines the relationship between diet and sleep, focusing on nutrients and foods that improve sleep quality.

Methods: A cross-sectional study included 87 male and female patients visiting the pulmonary OPD of SIMS hospitals with respiratory diseases, selected via convenience sampling. Ethics committee clearance was obtained (SIMS IEC/Others/27/2024). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PQSI), and food intake was evaluated using a Food Frequency Questionnaire through face-to-face interviews. Physical activity was assessed with the Global Physical Activity Questionnaire (GPQA). Anthropometric data and BMI were collected from patient files . Statistical tools used were frequency, Chi-Square Test, and Spearman rank correlation to examine the effect of food groups on sleep quality.

Results: Most participants were aged 61-69 years (33.3%), with 50.5% classified as overweight. 54% had respiratory diseases for 6-10 years. No significant impact (p>0.05) of non-vegetarian protein, starch, or vegetarian protein intake on sleep onset latency was observed. However, dairy and green leafy vegetables (GLV) impacted sleep onset latency (p<0.05). Dairy, starch, and vegetarian protein did not affect sleep quality (p>0.05), but GLV did (p<0.05). No significant impact (p>0.05) of non-vegetarian protein or starch on snoring was found. Dairy and vegetarian protein affected snoring (p<0.05). No significant impact (p>0.05) was observed for dairy, non-vegetarian protein, or starch on sleep trouble. Vegetarian protein and GLV did impact sleep trouble (p<0.05). Moderate-intensity sports had the best effect on sleep (p=0.048).

Conclusion: The study shows that vegetarian protein, dairy, and green leafy vegetables improve sleep quality. Moderate-intensity sports also positively impact sleep.
