Frequently Asked Questions

Sleepal is an AI-powered bedside companion that tracks your sleep quality, based on both physiological and ambient data, and personalized actionable suggestions to support healthier sleep habits.

Sleepal is designed for anyone who wants to improve their sleep experience. It’s especially helpful for busy professionals, students, parents, seniors, and people dealing with sleep challenges.

Unlike a regular smart lamp that only focuses on lighting control, Sleepal is purpose-built for sleep tracking and optimization. Every feature from light tones to soundscapes and routines are designed to help you understand how your physiology and environment affect your sleep quality and how to improve on it, over time.

Most sleep trackers only measure your sleep and show you reports afterward. Sleepal goes further by expanding on the gathered data with more physiological data such as sleep posture, and acoustic (such as snoring and breathing patterns), but also ambient using our humidity, luminosity sensors, through which we can actively assist optimizing your sleep quality. Also, we translate the raw data and provide you with actionable insights to improve on your sleep quality score, over time.

No. Sleepal is a wellness and lifestyle product designed to encourage healthier sleep habits. It does not diagnose or treat medical conditions, but it provides practical tools to help you build a more relaxing and consistent sleep routine.

Sleepal was created to make good sleep more accessible in a busy modern world. Many people struggle with stress, screens, and harsh alarms, so we built a gentle, intelligent device that supports your natural rhythm and provides actionable suggestions that will assist returning the user the quality sleep we all need.

Sleepal is designed to complement your existing health tools, not replace them. If you already use a smartwatch or fitness tracker to monitor sleep data, Sleepal works alongside those devices (via API integration) by combining the data so as to paint a more complete picture of sleep insights. Thereby providing in even more personalized suggestions via our Sleepal App.

Sleepal is designed to be practically accurate and scientifically validated, with performance measured against professional sleep-lab standards.

While Sleepal is not a medical device, its technology has been developed through over 2.5 years of research and refined using more than 2,500 PSG (polysomnography) validation nights. PSG is the gold-standard method used in clinical sleep studies to analyze real human sleep stages and physiological signals.

Based on this validation process, Sleepal has demonstrated the following performance results when compared directly to professional reference measurements:

• Heart Rate Accuracy: 95% (R² compared to ECG)
  Sleepal’s heart-rate tracking closely matches clinical ECG measurements, providing highly reliable everyday monitoring.

• Respiratory Tracking: RMSE of 0.41
  Compared with an abdominal respiratory belt, Sleepal shows a very small average discrepancy, indicating strong accuracy in measuring breathing patterns.

• Sleep Staging Accuracy: 78% with Kappa of 0.70 (vs. PSG)
  When classifying sleep stages (Wake, Light, Deep, REM), Sleepal achieves solid agreement with professional PSG scoring. A kappa of 0.70 is considered substantial agreement in sleep research.

The confusion matrix is a simple way to show how accurately Sleepal identifies sleep stages compared to professional PSG sleep-lab scoring. It compares what Sleepal predicted (Wake, Light, Deep, REM) with the true stages measured by PSG.

Higher percentages along the diagonal mean stronger agreement with PSG, while lower off-diagonal values show fewer misclassifications. In short, the matrix is a transparent visual summary of how reliably Sleepal recognizes real human sleep patterns.

The confusion matrix above below how accurately Sleepal identified sleep stages during PSG-validated testing with healthy adult subjects. Each row represents the true sleep stage measured by professional PSG scoring, while each column shows the stage predicted by Sleepal.

Higher percentages along the diagonal indicate stronger agreement with PSG, while lower off-diagonal values represent fewer misclassifications. These results demonstrate that Sleepal can reliably distinguish between Wake, Light, Deep, and REM sleep in typical healthy sleepers when tested under controlled sleep-lab conditions.

This data provides a transparent snapshot of Sleepal’s performance when evaluated against the gold-standard reference for sleep measurement.

The confusion matrix shown above reflects results from testing with adults experiencing OSA. Separate validation testing is also conducted with participants who experience sleep conditions such as obstructive sleep apnea (OSA) to evaluate Sleepal’s performance in more complex, real-world sleep patterns.

These studies compare Sleepal’s sleep staging directly with PSG measurements in individuals whose sleep may include more interruptions, irregular breathing events, or fragmented rest.

Sleepal is an all-in-one wellness device that combines adaptive lighting, calming soundscapes, guided breathing sessions, a personalized AI coach, and smart alarm functions into one simple bedside companion. It helps you relax at night, fall asleep more easily, and wake up gently in the morning. Everything works together automatically, so you can enjoy better sleep without complicated settings or extra devices.

Yes. Sleepal offers a calming alternative to screen time. Instead of reaching for your phone or other device, you can unwind with warm light, relaxing sounds, guided breathing or even story telling. This reduces stimulating blue-light exposure and encourages melatonin production which in turn supports healthier bedtime behavior.

Sleepal works contactlessly and effortlessly once your bedtime routine begins. Based on the data it gather, it gradually adapts to your natural rhythm and follows dimming lights, and eventually turning off. When connected with your smart home set up, it would enable the AI Lamp to operate and fine-tune or shut off connected devices, so you can simply fall asleep without needing to manage anything.

Research shows that exposure to blue-wavelength light in the evening can suppress the body’s melatonin production, delay sleep onset, and disrupt natural sleep rhythms. Using warm, low-blue light in the hours before bedtime helps support healthier sleep timing and makes it easier to fall asleep comfortably.

Guided breathing helps calm your nervous system and prepare your body for rest. Research has shown that slow, structured breathing exercises can reduce stress, lower mental and physical arousal, and improve overall sleep quality. Recent studies have found that breathing techniques—such as mindful and diaphragmatic breathing—can help people fall asleep faster, feel more relaxed before bed, and experience fewer sleep disturbances.

Sleepal’s guided breathing programs combine gentle audio cues with soft lighting to help you slow your breath, quiet your mind, and ease into a restful state. By giving you a simple, science-backed way to unwind at night, these sessions make it easier to transition naturally from a busy day into deeper, more restorative sleep.
