  "account": "A smart bed capable of adjusting skin temperature and bed microclimate was used to explore how six temperature settings influenced sleep architecture, autonomic activity, and brain activity in 18 adults. Over two nights, participants underwent separate overnight sleep studies in three-hour segments, with their allocated temperatures randomly assigned. By employing mixed-effects regression models, researchers evaluated the impact of these temperature changes on sleep and physiological indicators, while secondary analyses focused on sleep deepening, heart rate, and brainwave patterns. Results indicated that active temperature settings significantly altered sleep and physiological outcomes. All five active temperature settings altered sleep to become deeper, increasing the likelihood of slow-wave sleep (odds ratios ranging from 1.21 to 3.65, with high cooling exhibiting the most significant effect) and decreasing the likelihood of light non-rapid eye movement sleep compared to no temperature adjustment. Heating expedited the onset of deep sleep relative to cooling, without significantly affecting sleep onset latency, whereas cooling resulted in a gradual decrease in heart rate. Brainwave analyses identified different cortical patterns associated with the heating and cooling conditions. These findings demonstrate that active bed microclimate regulation can modify sleep architecture, autonomic activity, and cortical activity during sleep. The non-linear nature of these effects suggests the existence of \"thermal sweet spots\" that may differ across the night and between individuals, indicating the potential for personalized, programmable temperature-regulation strategies to optimize sleep quality.",
  "summary": "Skin temperature and bed microclimate are established modulators of human sleep, but most prior work has relied on passive thermal materials. We used a smart bed capable of heating or cooling the microclimate to investigate how six temperature settings affect sleep architecture, autonomic activity, and electroencephalographic (EEG) activity. Eighteen adults (9 male, 9 female; mean age 44.5 years)…",
