Poor sleep quality (PSQI > 5) is highly prevalent (55.8%) among university students and is strongly associated with higher levels of perceived stress, anxiety, and depressive symptoms.

If you are a university student, recognize that more than half of your peers likely have poor sleep quality. This is strongly linked to stress, anxiety, and depression. Prioritizing sleep hygiene is not just about rest; it is a critical component of mental health and academic success. Addressing sleep issues may help mitigate psychological distress.

Why this rating

Large sample size (N=2,551) and validated instruments (PSQI, DASS-21, PSS), but cross-sectional design limits causal inference.
