The study conducted by Biddle and Hamermesh (1990) offers valuable insights into how various factors such as total work hours (totwrk), education level (educ), and age influence sleep duration. Their regression model, which predicts sleep in minutes per week based on these variables, indicates that increases in work hours and education are associated with reductions in sleep, whereas age has a positive relationship with sleep duration. Specifically, the negative coefficient for totwrk (−0.15) suggests that for each additional minute a person spends working weekly, their sleep decreases by 0.15 minutes. This inverse relationship reflects the intuitive notion that more work commitments may encroach upon sleep time. Conversely, the positive coefficient for age (2.29) indicates that older individuals tend to sleep slightly more, which could be due to lifestyle adjustments or differing work responsibilities over the lifespan. The negative coefficient for education (−11.20) implies that higher educational attainment correlates with somewhat less sleep, potentially reflecting increased responsibilities or occupational demands associated with higher education levels.

These findings highlight the importance of the considered variables in explaining sleep patterns. However, it is imperative to assess whether totwrk, educ, and age sufficiently capture the complexity of factors affecting sleep. While they may account for a significant portion of the variability, human sleep behavior is influenced by a multitude of additional factors. For example, health status is a critical determinant—individuals with health issues or chronic conditions often experience disrupted or reduced sleep. Mental health factors such as stress, anxiety, or depression can significantly impact sleep quality and duration. Lifestyle habits, including physical activity levels, caffeine and alcohol consumption, and screen time before bed, also vary widely among individuals and can influence sleep patterns. Environmental factors such as noise, light exposure, and sleeping environment quality (e.g., mattress comfort, room temperature) are equally pertinent.

Furthermore, socio-economic status, work shifts or irregular hours, family responsibilities, and cultural attitudes towards sleep are additional influences that should be considered. For instance, shift workers with irregular schedules often face sleep deprivation or circadian rhythm disruptions that are not fully captured by the variables in the model. Including measures of sleep quality, stress levels, physical activity, health status, and environmental conditions could improve the explanatory power of the regression model. Advanced modeling techniques or longitudinal studies could further clarify the causal relationships and help distinguish correlation from causation. Ultimately, while totwrk, educ, and age are important factors, a holistic approach considering a broader spectrum of influences is necessary to fully understand the determinants of sleep.
