The Relationship between Sleep Quality and Posture: A Study on University Students

Area of Science:

• Biomechanics
• Sleep Science
• Public Health

Background:

• Poor body posture and head-neck alignment are prevalent among university students.
• Sleep quality is a critical factor influencing student well-being and academic performance.
• The interplay between physical activity, posture, and sleep quality requires further investigation.

Purpose of the Study:

• To examine the relationships between body posture, physical exercises, head-neck alignment, and sleep quality in university students.
• To identify potential correlations between lifestyle factors (caffeine, physical activity) and these health parameters.

Main Methods:

• Utilized the REEDCO Posture Evaluation (RPE) for body posture assessment.
• Employed the Apecs-AI Posture Evaluation and Correction System for head and neck measurements.
• Assessed sleep quality using the Pittsburgh Sleep Quality Index (PSQI).
• Conducted Pearson correlation analysis on data from 96 university students.

Main Results:

• Higher caffeine consumption correlated with poorer sleep quality (r = 0.267, p < 0.05).
• Increased physical activity was linked to better sleep quality (r = -0.278, p < 0.05) and improved body posture (REEDCO scores decreased, r = -0.423, p < 0.05).
• Specific head and neck posture deviations (right/left head scores) increased with physical activity but showed negative correlations with overall posture scores.

Conclusions:

• Physical activity appears to positively influence both sleep quality and body posture in students.
• While correlations exist, the complex relationship between head-neck posture, physical activity, and sleep quality necessitates more extensive research for definitive conclusions.
