NOCTURNAL DIGITAL MEDIA USAGE AS PREDICTOR FOR INSOMNIA RISKS AMONG UNIVERSITY LECTURERS IN SELECTED TERTIARY INSTITUTIONS, LAGOS STATE, NIGERIA

Nocturnal digital media usage is a common practice among the 21st century lecturer which predisposes them to unpalatable health outcomes. This study examines the relationship between nocturnal digital media usage and insomnia risks among university lecturers in selected tertiary institutions in Lagos State, Nigeria. This study adopts the correlational research design. Two research questions and hypotheses were postulated to guide the study. Population of this study comprised all university lecturers across selected institutions within Lagos State, from which a sample of 300 lecturers was purposively selected. Data were collected using a structured instrument titled “Nocturnal Digital media Usage and Insomnia Risks Questionnaire (NDMUIQ),” while a Cronbach’s alpha coefficient of 0.78 was gotten which is appropriate. The questionnaire was administered through an on-the-spot distribution and retrieval method. Data analysis involved descriptive statistics (frequency counts and percentages) for the demographics and inferential statistics of regression analysis tested the hypotheses at a 0.05 level of significance. Therefore, this finding reveals that there was no significant relationship between binge-watching streaming content and insomnia risks among university lecturers in Lagos State (r = 0.003, p = 0.000 > 0.05). Further analysis showed a significant relationship between late-night social media engagement and insomnia risks (r = 0.442, p = 0.000 < 0.05). Based on these findings, the study recommends that management of tertiary institutions should develop awareness programmes ON the health implications of harmful digital habits while such initiatives should be aimed at promoting healthier digital behaviours and improving sleep hygiene among academic staff.
