  • How AI Is Decoding Your Sleep Stages Without a Lab

    How AI Is Decoding Your Sleep Stages Without a Lab
    Jun 23 2026
    Sleep tracking has moved beyond counting hours. In this episode, Lucas and Luna explore how AI-powered wearables now decode sleep stages—REM, light, deep—with accuracy rivaling polysomnography. They examine a 2025 Stanford study comparing the Oura Ring, Apple Watch, and a new EEG headband against clinical sleep labs. The data shows consumer devices hit 88-92% accuracy for detecting sleep vs. wake, but still struggle with stage classification. Lucas breaks down the machine learning models behind the scenes: convolutional neural networks trained on thousands of nights of lab data. Luna questions whether this data is actionable for the average user. They discuss how insurers and employers are already using sleep-stage data in wellness programs, and the privacy implications of your brain waves being analyzed by subscription services. A concrete look at what your smart ring really knows about your sleep. #SleepTracking #AI #Wearables #OuraRing #AppleWatch #EEG #Polysomnography #MachineLearning #StanfordStudy #SleepHealth #DigitalHealth #HealthTech #Privacy #WellnessPrograms #Business #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • How Voice AI Is Detecting Depression from Your Speech Patterns

    How Voice AI Is Detecting Depression from Your Speech Patterns
    Jun 22 2026
    In Episode 67 of The Digital Health Podcast, Lucas and Luna explore how artificial intelligence is analyzing vocal biomarkers to screen for depression and mental health conditions. They focus on the work of companies like Kintsugi and Sonde Health, which use voice recordings to detect subtle changes in pitch, tone, and rhythm that correlate with depression. Lucas explains the science behind vocal biomarkers—how depression affects the muscles that control the vocal cords, leading to flattened prosody. Luna raises privacy concerns about voice data being recorded without consent, and they discuss ethical frameworks being developed. The hosts also connect this to the broader trend of passive mental health monitoring, where apps can detect depression from your phone microphone without you speaking at all. A concrete, forward-looking conversation about the promise and peril of AI listening for mental health. #DigitalHealth #MentalHealth #AI #VoiceAI #DepressionDetection #VocalBiomarkers #Kintsugi #SondeHealth #HealthTech #Business #Technology #MachineLearning #Privacy #Ethics #PassiveMonitoring #HealthcareInnovation #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • How AI Is Detecting Rare Diseases from Faces

    How AI Is Detecting Rare Diseases from Faces
    Jun 22 2026
    A single selfie could flag a rare genetic condition years before symptoms appear. Lucas and Luna explore how computer vision models are being trained to detect subtle facial markers of diseases like DiGeorge syndrome and Noonan syndrome. They look at the work of companies like FDNA and its Face2Gene platform, which has analyzed over 500,000 facial images to help clinicians narrow down diagnoses. They discuss the accuracy rates — around 90 percent for certain syndromes — and the ethical questions around consent, bias, and false positives. The conversation also touches on how these tools are being integrated into pediatric workflows and the potential for smartphone-based screening in underserved areas. A fascinating look at how AI is giving doctors a new diagnostic sense. #RareDisease #AI #ComputerVision #FacialRecognition #HealthTech #Genetics #FDNATechnology #Face2Gene #Pediatrics #Diagnostics #DigitalHealth #MachineLearning #HealthcareAI #Business #Technology #FexingoBusiness #BusinessPodcast #TheDigitalHealthPodcast Keep every episode free: buymeacoffee.com/fexingo

  • How AI Is Matching Patients to Clinical Trials in Days

    How AI Is Matching Patients to Clinical Trials in Days
    Jun 21 2026
    Clinical trial enrollment is notoriously slow — 80 percent of trials fail to meet enrollment targets on time, and patients often wait months to find out if they qualify. In this episode, Lucas and Luna look at how AI-powered matching platforms are compressing that timeline from months to days. They examine the case of Triall, a startup using natural language processing to scan electronic health records against trial eligibility criteria in real time. When a patient in a partner hospital system gets a new diagnosis, the AI cross-references their full medical history with thousands of active trials within 24 hours. Lucas walks through the specific technical challenge: unstructured clinical notes written in free text, which traditional keyword searches miss entirely. Luna flags the ethical tension — hospitals sharing data with a third-party AI — and the workaround using de-identified queries. They close on the economics: a single trial day costs drug companies an estimated $8 million in lost revenue, so even a modest speedup delivers billions in value. #ClinicalTrials #AI #Triall #PatientMatching #NaturalLanguageProcessing #HealthTech #DigitalHealth #DrugDevelopment #ElectronicHealthRecords #TrialEnrollment #Pharmaceutical #Biotech #Business #Technology #FexingoBusiness #BusinessPodcast #LucasAndLuna #HealthAI Keep every episode free: buymeacoffee.com/fexingo

    Jun 21 2026
    In this episode of The Digital Health Podcast, Lucas and Luna explore how wearable devices and remote monitoring tools are reshaping clinical trial design. They focus on a specific case: the use of Apple Watch, Fitbit, and continuous glucose monitors by a mid-size biotech firm to reduce trial costs by 30% and improve patient retention. Lucas explains how the FDA's 2023 guidance on digital health technologies paved the way, and Luna questions whether the data is reliable enough for regulators.
