On WorldSleepDay we ask: can sleep tracking really improve your sleep?
With so many different stats and figures to track, knowledge is power, right? Yes and no. To find out just how well a Fitbit can help improve your night's sleep, we took it and some other sleep devices for a whirl to see how effective and accurate they genuinely appear to be.Fitbit does a pretty good job of translating its plethora of stats and information in a way that makes sense to glance at.
Stick with wearing the Fitbit tracker for at least 14 days and you'll gain a monthly sleep profile. Fitbit could have chosen a soulless-looking description of your sleep type, but instead, it uses cute animals. For instance, mine has been a parrot during a lively period of my life, indicating that I was reasonably consistent with my sleep patterns.
I had valuable data even before I'd used my Fitbit Inspire 3 enough times to conjure up the latest sleep profile for the month. Being able to spot how much deep/REM sleep I'd achieved was a good indicator of how or why I felt tired that day. Similarly, the readiness score offers vital insight with – at the time of writing – a mere 1 out of 100 reminding me that I shouldn't have really done that HIIT session yesterday on top of a brisk walk and a busy day of work.
I went into the experiment thinking that my Withings Sleep Analyzer would rule the roost for sleep tracking. After all, it's a device that is placed under my mattress, so it can't be confused by my arms flailing in my sleep like a wearable could be. Having used older Fitbits years ago, Withings always came through for me, being far more accurate.

The long-term and short-term effects of ambient air pollutants on sleep characteristics in the Chinese population: big data analysis from real world by sleep records of consumer wearable devices - BMC MedicineSeveral studies on long-term air pollution exposure and sleep have reported inconsistent results. Large-scale studies on short-term air pollution exposures and sleep have not been conducted. We investigated the associations of long- and short-term exposure to ambient air pollutants with sleep in a Chinese population based on over 1 million nights of sleep data from consumer wearable devices. Air pollution data including particulate matter (PM2.5, PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3) were collected from the Ministry of Ecology and Environment. Short-term exposure was defined as a moving average of the exposure level for different lag days from Lag0 to Lag0-6. A 365-day moving average of air pollution was regarded as long-term exposure. Sleep data were recorded using wearable devices from 2017 to 2019. The mixed-effects model was used to evaluate the associations. We observed that sleep parameters were associated with long-term exposure to all air pollutants. Higher levels of air pollutant concentrations were associated with longer total sleep and light sleep duration, shorter deep sleep duration, and decreases in wake after sleep onset (WASO), with stronger associations of exposures to NO2 and CO [a 1-interquartile range (IQR) increased NO2 (10.3 μg/m3) was associated with 8.7 min (95% CI: 8.08 to 9.32) longer sleep duration, a 1-IQR increased CO (0.3 mg/m3) was associated with 5.0 min (95% CI: − 5.13 to − 4.89) shorter deep sleep duration, 7.7 min (95% CI: 7.46 to 7.85) longer light sleep duration, and 0.5% (95% CI: − 0.5 to − 0.4%) lower proportion of WASO duration to total sleep]. The cumulative effect of short-term exposure on Lag0-6 is similar to long-term exposure but relatively less. Subgroup analyses indicated generally greater effects on individuals who were female, younger (| 45 years), slept longer (≥ 7 h), and during cold seasons, but the pattern of effects was mixed. We supplemented two additional type

Better sleep, better life? testing the role of sleep on quality of lifePrevious research has shown that sleep deprivation, low quality sleep or inconvenient sleeping times are associated with lower quality of life. However, research of the longitudinal effects of sleep on quality of life is scarce. Hence, we know very little about the long-term effect of changes in sleep duration, sleep quality and the time when individuals sleep on quality of life. Using longitudinal data from three waves of the Czech Household Panel Study (2018–2020) containing responses from up to 4,523 respondents in up to 2,155 households, the study examines the effect of changes in sleep duration, sleep quality and social jetlag on satisfaction with life, happiness, work stress, subjective health and wellbeing. Although sleep duration and timing are important, panel analyses reveal that sleep quality is the strongest predictor of all sleep variables in explaining both within-person and between-person differences in quality of life indicators.
