The burgeoning world of sleep-tracking technology, while promising greater insight into our nightly rest, may inadvertently be fuelling anxiety and stress for a significant portion of its users, particularly those grappling with insomnia. A recent study from the University of Bergen in Norway has shed light on this complex relationship, revealing that while these digital tools can offer valuable data for some, they can also amplify worries and heighten self-awareness of sleep quality in detrimental ways.
The rapid evolution of sleep app technology presents a challenge for the scientific community to keep pace with these advancements. Researchers observed that younger adults, aged 18-35 and 36-50, were more profoundly affected by the feedback provided by these apps. While they reported more perceived benefits, such as improved sleep patterns and a greater inclination to prioritise rest, they also confessed to experiencing heightened levels of stress and concern. This suggests a potential vulnerability among younger demographics to the deluge of digital health information and its psychological impact.
The sleep-tracking market is experiencing explosive growth. Projections indicate that the Australian sleep-tracking devices market, which generated an estimated $5 billion (approximately $6.7 billion AUD) in 2023, is on track to double its revenue by 2030, according to market research firm Grand View Research. These devices, most commonly integrated into smartwatches and fitness bands, employ an array of sensors to meticulously monitor and report on various sleep parameters. Key metrics include sleep latency (the time it takes to fall asleep), sleep duration, and sleep efficiency (the percentage of time spent asleep while in bed).
The Double-Edged Sword of Sleep Data
The University of Bergen study involved surveying over a thousand individuals in Norway, with an average age of 50. Participants were quizzed on their usage of sleep apps, their current sleep health, and any specific positive or negative effects they attributed to these technologies. The findings underscored age as a pivotal factor influencing user experiences.
While younger age groups reported a tendency towards beneficial outcomes, such as enhanced sleep quality and a more proactive approach to sleep hygiene, they also exhibited a greater propensity for stress and worry. This duality points to a critical consideration: the constant barrage of data about one’s sleep can become a source of anxiety, especially when that data doesn’t meet perceived ideal benchmarks.
Amplifying the Worries of Poor Sleepers
The study’s authors sounded a clear warning: an overemphasis on the data generated by sleep apps can, paradoxically, lead to a deterioration in actual sleep quality. This is particularly true for individuals who already struggle with sleep disturbances.
Karl Erik Lundekvam, the second author of the study, highlighted that individuals experiencing insomnia symptoms were significantly more susceptible to negative repercussions from sleep-tracking apps. He noted that feedback from these devices was more likely to trigger stress and apprehension within this group. People who suffer from insomnia often possess an heightened “attentional bias” towards sleep-related cues and harbour a greater degree of worry, tendencies that monitoring devices can readily exacerbate.
Navigating the Digital Sleep Landscape
Lundekvam offered practical advice for those finding themselves increasingly stressed by their sleep apps. He urged users to first educate themselves about the specific metrics their apps measure and to critically assess the accuracy of this data. If this informational approach fails to alleviate concerns, he strongly recommended considering alternative strategies.
“If this does not calm your worries, you should consider taking off your sleep app device during nighttime or turning off notifications,” he advised. This suggestion aims to break the cycle of constant monitoring and the associated anxiety.
Despite these concerns, the researchers acknowledged that sleep apps can serve as valuable motivators for adopting healthier sleep habits. For instance, the data can encourage users to minimise screen time before bed or establish more consistent sleep schedules. The key lies in a balanced and mindful approach, where the technology serves as a tool for positive change rather than a source of constant self-scrutiny and stress. The challenge for both users and developers is to harness the power of sleep data without succumbing to its potential psychological pitfalls.
