So it\u2019s hardly surprising people are more concerned than ever about getting enough sleep. This blossoming interest has seen an explosion of sleep trackers which measure how many hours of sleep you get each night.<\/p>\n<p>As we sleep, we go through cycles of \u201cdeep,\u201d \u201clight,\u201d and \u201crapid eye movement\u201d (REM) sleep. The \u201cdeep\u201d portion of our sleep is mainly what leaves us feeling refreshed the next day. Most sleep trackers are a watch worn on the wrist, and work by monitoring your body movements as you sleep to determine how much time you probably spent awake versus asleep. Some devices also look at heart rate changes during sleeping to estimate how much time you spent in each sleep cycle.<\/p>\n<p>Despite their popularity, only a few studies have investigated how accurate sleep devices are. So far, research has found that compared to polysomnography tests \u2013 which experts use to diagnose sleep disorders \u2013 sleep trackers are only accurate <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31154154\/\">78% of the time<\/a> when identifying sleep versus wakefulness. This accuracy drops to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31154154\/\">around 38%<\/a> when estimating how long it took participants to fall asleep.<\/p>\n<p>Polysomnography tests are the most accurate because they track a person\u2019s brain waves, heart rate, breathing, blood oxygen levels, and body and eye movements during sleep through electrodes attached to the skin and scalp. Analyzing brain wave patterns is the only definitive way of knowing whether someone is awake or asleep, and to know what stage of sleep they\u2019re in.<\/p>\n<p>But since sleep trackers are worn on the wrist, they make their estimates of nightly sleep by measuring body movement and sometimes heart rate data. As we move frequently during all stages of sleep, movement provides few clues about what sleep stage we\u2019re in. Many sleep devices also fail to differentiate one stage of sleep from another <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/14998254\/\">based on motion alone<\/a>.<\/p>\n<p>Given many consumer sleep devices haven\u2019t been compared against polysomnography tests, it\u2019s difficult to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31621129\/\">determine their accuracy rate<\/a>. Furthermore, the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3109647\/#:%7E:text=Key%20Limitations%20of%20Wrist%20Actigraphy,sleep%20in%20certain%20patient%20groups\">algorithms which companies use<\/a> to make predictions about sleep are unknown, making it difficult for scientists to identify whether the assumptions made by the sleep devices are valid.<\/p>\n<p>Studies also show sleep devices underperform in people with insomnia. People with insomnia tend to remain very still in bed in an attempt to fall asleep. But as sleep trackers only measure movement, one study found watches were unable to <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/31621129\/\">differentiate sleep from wakefulness<\/a> in people with insomnia.<\/p>\n<p>Watches that incorporate <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6760396\/\">heart rate data<\/a> tend to be <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/32215550\/\">slightly more accurate<\/a> when measuring sleep duration because <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s41598-019-49703-y\">heart rate fluctuates<\/a> during different sleep stages. However, even in devices that do track heart rate, many experts are still uncertain of their accuracy because of the limited research on them, and because of the differences between each device. For example, one study of heart rate sleep trackers showed that two consumer devices tended to underestimate the amount of deep sleep wearers obtained by <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6760396\/\">as much as 46 minutes<\/a>.<\/p>\n<p><em>[Read:\u00a0<span dir=\"auto\">How Netflix shapes mainstream culture, explained by data<\/span>]<\/em><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Sleep_anxiety\"><\/span>Sleep anxiety<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Ultimately, this leads to the question of whether knowing about our sleep is actually beneficial to us.

Participants were given sleep watches and asked to complete measures of mood, daytime thinking processes and sleepiness at regular periods throughout the day.
