Sleep Analysis

Discover what sleep means to you and how well-prepared you are for the day ahead.

What Is Sleep Analysis?

How well did you sleep last night? Sleep is a complicated subject and making sense of it requires a variety of perspectives. There are days when you wake up after 6-7 hours of sleep feeling great, and there are days when 8 hours don’t feel like nearly enough. Some people tend to recover faster or slower than others and require more or less sleep to achieve the same benefits.

Firstbeat Analytics’ Sleep Analysis brings various aspects of your sleep together with singular purpose. That goal is to uncover what goes into a good night’s sleep for you, personally. This is done through comparisons with expert recommendations for duration and sleep structure, along with insight into the restorative power of your sleep. The result is a Sleep Score (0-100) that succinctly reports how well you slept. A detailed description of elements that contributed to your Sleep Score (e.g., duration, stages, restorative quality) can also be included.

How Does It Work?

Sleep is a complex and multidimensional phenomenon, the full meaning of which isn’t fully understood by science. What we do know is that sleep is instrumental in a range of recovery processes and facilitates the restoration of bodily resources. We also know that specific sleep durations and structural patterns are associated with better health outcomes, performance, and longevity.

Expert recommendations for age appropriate sleep duration, like those offered by the National Sleep Foundation, provide one basis for sleep evaluation. Recommendations for sleep structure and distribution of sleep stages (i.e. REM, light, deep sleep), how long it takes to fall asleep, and the number of awakenings during the night offer additional dimensions for assessing sleep quality.

Insight into the restorative power of sleep is obtained by observing activity within your autonomic nervous system (ANS). Changes in the length of time between consecutive heart beats (HRV) can be analytically transformed into a window through which autonomic nervous system (ANS) activity can be observed. The degree of activity within the parasympathetic (rest-and-digest) branch of your ANS relative to the sympathetic (fight-or-flight) branch is interpreted to reveal the presence and intensity of recovery states as they occur in your body. The result is an ability to understand sleep from the perspective of restorative power.

To provide your Sleep Score, these elements of sleep duration, sleep structure and restorative power are brought together in a complementary way. This means that, for example, shorter sleep with greater restorative power can be just as good as longer but more restless sleep.
