How does Sahha derive a sleep score without a wearable?
Sahha enables enterprises to leverage sleep tracking without requiring users to wear a smartwatch or fitness band. Using just a smartphone, we estimate key sleep metrics like total sleep time, sleep consistency, sleep debt, and circadian alignment. If users have wearables, we provide deeper insights into sleep continuity, mental recovery, and physical recovery. By leveraging both smartphone-based and wearable-integrated tracking, enterprises can provide sleep insights to a wide range of users, ensuring inclusivity and scalability.
How does Sahha track sleep without a wearable?
Most sleep trackers measure heart rate and movement to infer sleep stages which provide valuable information about the sleep session. However, not everyone has or wants to use these trackers. Sahha offers a data-driven alternative by enabling sleep tracking via smartphones. This approach allows enterprises to integrate passive, scalable sleep tracking into their applications and services, enabling valuable health insights without requiring additional hardware. Here’s how:
- Total Sleep Time: We estimate sleep duration by detecting long periods of phone inactivity. If a phone isn’t used between 11 PM and 7 AM, we infer about 8 hours of sleep. While this method may not be as precise as a wearable, it provides a reliable estimation for most users.
- Sleep Regularity: Consistency in sleep patterns is essential for overall well-being. We track how stable a user’s bedtime and wake-up time are over days and weeks, providing insights into whether they maintain a structured sleep schedule.
- Circadian Alignment: Aligning sleep schedules with natural circadian rhythms supports better rest. We assess how well a user’s sleep aligns with their usual schedule and environmental cues like sunrise and sunset.
- Sleep Debt: Chronic sleep deprivation accumulates over time, leading to reduced cognitive function, mood swings, and lower energy levels. Sahha calculates sleep debt to help users recognize when they need to catch up on rest and maintain long-term sleep health.
What additional insights do wearables provide?
For users who have sleep trackers connected, Sahha provides a more comprehensive sleep analysis, adding more key aspects of sleep health derived from sleep stages:
- Sleep Continuity: Wearables detect night-time wake-ups, duration of wakefulness, and sleep disturbances. This provides a clearer picture of sleep fragmentation and overall sleep stability.
- Mental Recovery: REM sleep is crucial for cognitive processing, memory consolidation, and emotional stability. Wearables track REM sleep duration, helping users understand their brain's recovery during sleep.
- Physical Recovery: Deep sleep is when the body undergoes the most repair, including muscle growth, tissue regeneration, and immune function support. Wearables provide granular data on deep sleep quality, offering a better understanding of physical recovery.
Why is smartphone-based sleep tracking useful?
Sahha’s smartphone-based approach ensures that enterprises can offer sleep insights to all users, including those without wearables. While wearables provide additional details, smartphone-based tracking remains a highly accessible and cost-effective way to measure sleep health trends. This enables companies to reach a broader audience without requiring users to invest in specialized hardware, making it ideal for scalable wellness solutions, employee health programs, and consumer-facing sleep tracking applications.
The Bottom Line
Sahha makes sleep tracking flexible, inclusive, and actionable. Whether Sahha's sleep score is based on smartphone-based tracking or enhanced with wearable data for deeper insights, it provides meaningful sleep analysis that helps users improve their rest and overall well-being. Enterprises can leverage the sleep insights in wellness platforms, healthcare applications, employee well-being programs and more, to drive engagement and improve health and business outcomes at scale.
