Hacking Our Sleep: When Data Dreams Don’t Match Reality
The global obsession with sleep optimization is booming. A quick search online reveals an overwhelming array of tools and products designed to help us hack our way to a good night’s rest. From smart mattresses that adjust temperature to sleep-tracking apps, technology offers a trove of new ways to monitor and manipulate our slumber. But is this quest for perfect sleep through data and gadgets truly beneficial?
The answer, according to leading sleep experts, is complicated. While an understanding of healthy sleep patterns has clearly grown, the emergence of sleep-tracking devices and apps brings a host of questions about their true efficacy and potential downsides.
The Science of Sleep: More Than Just Counting Sheep
Consistently racking up enough sleep is crucial for physical and mental wellbeing, as countless studies have revealed.
Prof. Russell Foster, director of the University of Oxford research institute studying sleep’s impact on illness, emphasizes the foundational role of sleep: "It’s fundamental to life. We have yet to come across an animal that doesn’t sleep."
Sleep deprivation, research shows, has far-reaching consequences. It disproportionately increases the risk of chronic diseases:
- Hypertension
- Coronary heart disease
- Type 2 diabetes
- Obesity
- Cancer
Beyond purely physical effects, researchers have observed that sleep deprivation also impacts our mood and cognitive function. Think of it this way – a tired brain remembers negativity more readily, meaning a lack of sleep can negatively bias our entire outlook on life.
Sleep also plays a crucial role in problem-solving, creativity, and memory consolidation. It’s during sleep that our brains process the inundation of information we absorb throughout the day.
The Race to Analyze Sleep: Are We Obsessing Too Much?
Despite understanding the vital role sleep plays, a significant percentage of adults struggle to get enough. A 2019 Irish Department of Health report found that 56% of adults were sleep-deprived, averaging less than seven hours of sleep per night.
And yet, the growing availability of sleep trackers and smart mattresses hasn’t necessarily translated into more restful nights. Prof. Andrew Coogan, director of the Maynooth University chronobiology and sleep laboratory, suspects that the focus on tracking and optimizing sleep could be counterproductive.
"Good sleepers don’t tend to think about sleep a lot," he observes, while acknowledging that bad sleepers are more likely to fixate on getting better sleep.
The sleep tracker industry, he emphasizes, preys on existing anxieties.
Another contributing factor is the widespread belief that there’s a magic number of sleep hours universally beneficial for everyone. Prof. Foster challenges this. “Taking the population average of eight hours and applying it to everyone is nonsense," he says. "Some of us get by perfectly well on six, while others need closer to 11."
He argues that relying on a single metric, often based on simplified algorithms, ignores the diversity of individual sleep needs.
From Data to Distress: The Downside of Sleep Trackers
Many sleep trackers operate on faulty assumptions.
In a 2018 study, Dr. Dimitri Gavriloff of the Sleep and Circadian Neuroscience Institute found similar results. Participants given fake sleep scores saw significant changes in their mood and wellbeing despite the tracker’s data being entirely fabricated.
This study highlights how tracking devices can inadvertently magnify sleep anxiety, leading to a vicious cycle of yep-
worrying about sleep rather
than getting more of it.
When our focus shifts to data tracking and comparisons, we move further away from the natural rhythms and cues that best serve our individual biological needs.
The Back to Basics Approach: Reclaiming our Sleep
While technology undoubtedly plays a role in our understanding of sleep, experts emphasize the importance of returning to fundamental sleep hygiene.
Prof. Coogan recommends ditching the sleep trackers and focusing on establishing healthy routines:
-
Aim for a consistent sleep schedule, going to bed and waking up around the same time each day, even on weekends.
-
Relax before bed by avoiding anxieties over finances or housework at bedtime
- Create a calming environment opting for darkness, quiet, and a cool temperature.
Prof. Foster emphasizes the importance of mental attitude. "We need to relax," he says, "If we could appreciate the sleep we get rather than fretting over what we don’t get, we’d all sleep much more soundly."
If you struggle with persistent sleep problems, don’t hesitate to consult your doctor. There are issues that require professional intervention, and a doctor can guide you toward customized solutions.
