Abstract

Lifestyle practices play an important role in shaping sleep quality and psychological health among postgraduate students who constantly experience academic stress, asymmetrical routines and prolonged screen exposure. The present study is quantitative in nature. A descriptive in which  correlational study examined the relationship between lifestyle practices, insomnia and psychological well-being among 100 postgraduate students. The sample comprised of an equal gender distribution of 50 males and 50 females. Data were collected by using self- made tools including a Lifestyle Practices assessing sleep hygiene behaviors, physical activity, dietary regulation, caffeine consumption, screen exposure before bedtime, and relaxation practices, the Insomnia Severity Index measuring sleep disturbance and daytime impairment, and Well-Being tool to evaluate positive mood, vitality, and life satisfaction. Descriptive statistics indicated a moderate level of healthy lifestyle practices (M = 3.19, SD = 0.69), moderate insomnia severity (M = 16.2, SD = 5.8), and below-average psychological well-being (M = 48.5, SD = 7.3). Pearson’s product–moment correlation analysis revealed a statistically significant negative relationship between lifestyle practices and insomnia severity (r = −0.57, p < .001), indicating that students who reported healthier lifestyle behaviors experienced lower levels of insomnia. A statistically significant positive correlation was found between lifestyle practices and psychological well-being (r = 0.49, p < .001), suggesting that better lifestyle habits were associated with higher levels of well-being. Additionally, insomnia severity demonstrated a strong negative correlation with psychological well-being (r = −0.65, p < .001), indicating that greater sleep disturbance was associated with poorer psychological health. These findings determined that healthier lifestyle practices are significantly associated with reduced insomnia and enhanced psychological well-being among postgraduate students, highlighting the importance of promoting positive daily habits to support sleep health and overall mental well-being within higher education settings.
