Study Shows Irregular Sleep Patterns and Dissatisfaction Among Young Australians

A recent study published in the Australian and New Zealand Journal of Public Health sheds light on the sleep health of young Australians and its significant relationship with their physical and mental well-being. Conducted as part of the Raine Study in Western Australia, this groundbreaking research is the first of its kind in Australia to comprehensively investigate sleep health in young adults. 

The study, which involved 1,234 participants, revealed alarming trends in the sleep patterns of young Australians. Astonishingly, 60 percent of the respondents reported irregular sleep hours, indicating a lack of consistency in their nightly sleep routines. Furthermore, 30 percent of the young adults admitted to sleeping less than the recommended seven to nine hours per night, while 18 percent reported taking more than 30 minutes to fall asleep. These findings indicate that a significant proportion of young people are experiencing suboptimal sleep. 

Perhaps more concerning was the fact that many young adults expressed dissatisfaction with their sleep quality. A quarter of the participants rated their sleep as “fairly bad” or “very bad,” and 10 percent reported impaired daytime alertness. Surprisingly, the study found that self-reported sleep satisfaction and daytime alertness had the strongest correlation with young adults’ mental and physical health. 

Dr. Alex Metse, the lead researcher and a Clinical Psychologist at UniSC, expressed surprise at these results, highlighting that the commonly promoted notion of seven to nine hours of sleep for good health may not be sufficient for everyone. The study found that those who were dissatisfied with their sleep experienced mental health scores that were 34 percent lower and physical health scores that were seven percent lower compared to those satisfied with their sleep. Additionally, individuals who felt less alert during the day or slept less than the recommended duration also exhibited lower mental health scores. 

Previous research has linked poor sleep to various chronic health conditions, including depression and cardiovascular diseases. This new study not only establishes a clear connection between sleep and physical and mental health but also provides valuable insights into the indicators of good sleep for overall health. 

The study’s focus on sleep satisfaction being a subjective measure suggests opportunities to educate the public about what constitutes a “normal” night’s sleep. By managing expectations and promoting healthy habits, it may be possible to improve sleep satisfaction among young adults. Health practitioners can utilize simple questions about sleep satisfaction and daytime alertness to identify individuals at risk of experiencing poor physical and mental health due to inadequate sleep. 

Adjunct Prof Terry Slevin, CEO of the Public Health Association of Australia, emphasizes the importance of raising awareness about the significance of sleep for overall well-being. While sleep disorders like insomnia and sleep apnea have long been known to impact health negatively, this study highlights that suboptimal sleep, even without a diagnosed disorder, is a public health concern akin to nutrition and physical activity. 

Young adults are particularly susceptible to poor sleep, given that they are in a crucial transition phase where they establish habits that may shape their future health outcomes. Thus, focusing on both the quantity and quality of sleep is essential in promoting healthier lifestyles among this demographic. 

The study’s findings underscore the necessity of prioritizing sleep as a critical public health issue. Just as individuals pay attention to their diet and physical activity, the impact of sleep on overall health should not be underestimated. By considering sleep as one of the pillars of good health, people can become more mindful of their sleep patterns and take proactive measures to improve them. 

The research on the sleep health of young Australians highlights the pressing need for increased awareness and action regarding the impact of irregular sleep on physical and mental well-being. By acknowledging the importance of quality sleep and implementing measures to improve sleep patterns across all age groups, individuals can foster healthier and more resilient populations.
