In August 2023, SLEEPON conducted a survey targeting existing customers, and the statistics revealed that over 66% of users use sleep monitors because they experience sleep-related difficulties. But have you ever had doubts? People sleep every day, how is the quality of sleep assessed?

In the past, people often used subjective forms, such as questionnaires, to assess sleep quality. This method relied on individuals’ self-perception and recollection, leading to potential subjectivity and inaccuracy. With technological advancements, SLEEPON APP 3.0 sleep assessment adopts new algorithms, one of which is based on the SOAP (Subjective, Objective, Assessment, Plan) method from the U.S. healthcare system.

The upgraded algorithm of SLEEPON APP 3.0 comprehensively evaluates sleep quality by combining subjective and objective data. The following are parts of assessment factors that these algorithms may include:

Subjective Assessment (S – Subjective):

Questionnaires: Although a predominant method in the past, the questionnaires of SLEEPON APP 3.0 may be more refined and objective to reduce subjectivity. For example, regularly filling out the PSQI questionnaire survey, daily documenting sleep-influencing factors such as coffee, alcohol, mental stress, etc.

Objective Assessment (O – Objective):

• Physiological Indicators: Utilizing Go2sleep tracker to obtain objective data like SPO2, heart rate, HRV, temperature (to be added in future) etc.
• Motion Tracking: Analyzing changes in body movement to determine different sleep stages.

Assessment (A – Assessment):

• Sleep Stage Analysis: Based on physiological indicators and motion tracking, the algorithm can estimate different sleep stages such as wakefulness, REM (Rapid Eye Movement), and non-REM stages.
• Sleep Cycle Assessment: Evaluating the quality and structure of the entire sleep cycle.

Depending on the different sleep stages, sleep undergoes the following main processes. The scores vary based on the impact on the body during different sleep stages.

1. Wakefulness Period : At the beginning of sleep, individuals are in a wakeful state, preparing to enter sleep.
2. Non-REM Stages (N1, N2 & N3): Divided into three stages, including light sleep and deep sleep. The processes of body repair and growth mainly occur during deep sleep.
3. REM Stage: Rapid Eye Movement stage, where dreaming typically occurs. Brain activity is similar to wakefulness, but muscles are relaxed.

Plan (P – Plan):

Recommendations and Improvements: Based on assessment results, the algorithm can generate suggestions driven by AI to help individuals improve sleep quality, including appropriate sleep duration, lifestyle changes, etc.

By synthesizing subjective and objective data, SLEEPON APP 3.0 sleep assessment algorithms can more accurately evaluate sleep quality and provide personalized recommendations to improve sleep health.
