What you eat today shapes your sleep tonight. On higher-fiber, more plant-diverse days, people experience more deep and REM sleep, less light and fragmented sleep, and have a lower overnight heart rate. On days with more processed foods and saturated fat, nighttime wakefulness tends to be higher with a less restorative sleep pattern (less deep/REM sleep). And when dinner makes up a larger share of daily calories, people sleep longer with a higher overnight heart rate. A longer interval between one's last meal and bed time (about 4 vs. 2 hours) is associated with a lower overnight heart rate. Long-term healthy eating patterns are essential for good sleep, but this new study argues that even day-to-day dietary variations affect how well or how poorly we sleep.

Nuevo estudio publicado sobre el TDAH como desorden circadiano. Muchos casos de TDAH van acompañados de alteraciones del ritmo circadiano (cronotipo vespertino, sueño tardío, melatonina/cortisol desfasados). Intervenciones cronoterapéuticas (luz brillante por la mañana, melatonina, hábitos de sueño) podrían mejorar tanto el sueño como los síntomas del TDAH. frontiersin.org/journals/psych…

A new study using #NSRR data finds that in pediatric #OSA, higher BMI and larger waist/neck circumference were associated with poorer sleep outcomes. Findings underscore the importance of jointly addressing obesity and sleep in child health strategies. onlinelibrary.wiley.com/doi/10.1111/js…

🚨 New publication alert! 🚨 Now in Journal of Sleep Research: We analysed how baseline anthropometric markers predict objective sleep quality at follow-up in school-aged children with OSAS. 🔗 onlinelibrary.wiley.com/doi/10.1111/js… #Sleep #OSAS #children #ESRS #Obesity

Poor sleep fuels #inflammation—even without obesity! 🛏️🔥 A study in The Journal of Immunology finds sleep disruption increases inflammatory cells, but the good news? It's reversible with better sleep! Prioritize rest for better health. ow.ly/zUz750V7Zxz #SleepHealth

🌞 Men spend 52% more time in bright light than women, starting in childhood, according to a study of 11,000+ people. Light impacts our internal clocks and health, highlighting how lifestyle differences shape well-being. How does light affect your day? ow.ly/Kzil50UxqcB

🚨 Investigadores advierten que el exceso de tiempo frente a pantallas en niños de preescolar puede afectar su calidad de sueño y aumentar problemas de comportamiento como hiperactividad y falta de atención. Paper: doi.org/10.1080/030044…

A new study highlights how signals from the liver to the brain influence eating patterns tied to circadian rhythms. The liver-brain communication can get disrupted in people working night shifts or irregular hours leading to weight gain & metabolic issues. ow.ly/B2EK50U8iN8

Circadian-informed lighting improved sleep, sleepiness, and vigilance compared to control lighting. These findings support the potential for lighting interventions to improve sleep and vigilance in night shift workers chronically exposed to dim lighting. ow.ly/h6eo50U4Gwo

Based on this preprint, #sleep inertia (difficulty waking up) may explain the prior association of evening #chronotype with greater risk of #psychiatric conditions: Evening types _without sleep inertia_ were not at higher risk compared with morning types. #circadian
