Two 2026 studies — by Bilal et al. in Nature Communications and Thapa et al. in Nature Medicine — report that patterns within sleep data contain signals linked to future health outcomes, beyond what is currently used in clinical practice. Both papers build on earlier research showing sleep changes can precede diagnosis of various diseases.
A tech newsletter digest compiles several unrelated stories, including scammers using sextortion tactics within family group chats, an assessment of which wearable devices give the most reliable sleep data, and a reported change in leadership within Apple's executive ranks.
Sleep tracking devices like Oura and similar wearables often produce numbers that aren't precisely accurate, according to physicians. Despite this, doctors say the data can still help users identify personal patterns and trends in their sleep over time.
