   How Physical Activity Helps You Sleep Better and Stress Less – Jin Wen (Pt3)

   "Can physical activity really help you sleep better and manage stress?" In this third episode, Dr. Olli Tikkanen continues the conversation with sleep researcher Jin Wen, exploring how physical activity interacts with sleep and stress. Jin discusses how daily movement can improve sleep quality and reduce stress, but it’s not just about burning energy. She shares insights from research showing that regular physical activity helps maintain homeostasis, which can lead to better sleep and lower stress levels. Jin also introduces the SATED model, which evaluates different aspects of sleep, including satisfaction, alertness, timing, and duration. This holistic approach helps people understand how sleep quality goes beyond just getting enough hours of rest. Additionally, Jin highlights a growing issue in modern life - revenge sleep procrastination, where people sacrifice sleep to reclaim personal time, potentially affecting both their sleep and long-term health. If you want to learn how physical activity, sleep, and stress are interconnected, this episode is filled with practical insights and research findings. --- This podcast episode is sponsored by Fibion (https://web.fibion.com/) Inc. | Better Sleep, Sedentary Behavior and Physical Activity Research with Less Hassle --- Collect, store and manage SB and PA data easily and remotely - Discover ground-breaking Fibion SENS (https://web.fibion.com/sens/). --- SB and PA measurements, analysis, and feedback made easy - Learn more about Fibion Research (https://web.fibion.com/research/). --- Learn more about Fibion Sleep (https://web.fibion.com/sleep/) and Fibion Circadian (https://web.fibion.com/circadian/) Rhythm Solutions. --- Fibion Kids (https://web.fibion.com/kids/) - Activity tracking designed for children. --- Explore our Wearables (https://web.fibion.com/articles/category/wearables/), Experience sampling method (ESM) (https://web.fibion.com/articles/category/experience-sampling-method/), Sleep, (https://web.fibion.com/articles/category/physical-behaviours/sleep/) Heart rate variability (https://web.fibion.com/articles/category/wearables/heart-rate-variability/) (HRV), Sedentary Behavior (https://web.fibion.com/articles/category/physical-behaviours/sedentary-behavior/)and Physical Activity article collection (https://web.fibion.com/articles/category/physical-behaviours/physical-activity/)s for insights on related articles. --- Refer to our article "Physical Activity and Sedentary Behavior Measurements" (https://web.fibion.com/articles/sedentary-behavior-physical-activity-measurements/) for an exploration of active and sedentary lifestyle assessment methods. --- Learn about actigraphy in our guide: Exploring Actigraphy in Scientific Research: A Comprehensive Guide (https://web.fibion.com/articles/actigraphy-scientific-research-guide/). --- Gain foundational ESM insights with "Introduction to Experience Sampling Method (ESM) (https://web.fibion.com/articles/experience-sampling-method-guide-2023)" for a comprehensive overview. --- Explore accelerometer use in health research with our article "Measuring Physical Activity and Sedentary Behavior with Accelerometers " (https://web.fibion.com/articles/accelerometer-measuring-physical-activity-sedentary-behavior/). --- For an introduction to the fundamental aspects of HRV, consider revisiting our Ultimate Guide to He

   Sleep as a Reset: How a Bad Night Affects Your Stress Response – Jin Wen (Pt2)

   &quot;Does poor sleep impact your stress more than stress affects your sleep?&quot; In this second episode, Dr. Olli Tikkanen continues his insightful discussion with sleep researcher Jin Wen, diving deeper into the fascinating relationship between daily stress and sleep. Jin explains that while stress and sleep influence each other, poor sleep has a more direct impact on how we handle stress the next day. This episode explores the nuances of how sleep acts like a reset button, and when that reset is faulty, it can shape our reactions to daily hassles. Jin also sheds light on how chronic stress differs from daily stress and how physiological markers like cortisol play a role in both. She discusses the use of objective measures such as cortisol and heart rate variability in understanding the body&#39;s response to stress and sleep quality. If you&#39;re curious about the science of sleep, stress, and their effects on your daily life, this episode provides thought-provoking insights and practical research findings. --- This podcast episode is sponsored by Fibion (https://web.fibion.com/) Inc. | Better Sleep, Sedentary Behavior and Physical Activity Research with Less Hassle --- Collect, store and manage SB and PA data easily and remotely - Discover ground-breaking Fibion SENS (https://web.fibion.com/sens/). --- SB and PA measurements, analysis, and feedback made easy - Learn more about Fibion Research (https://web.fibion.com/research/). --- Learn more about Fibion Sleep (https://web.fibion.com/sleep/) and Fibion Circadian (https://web.fibion.com/circadian/) Rhythm Solutions. --- Fibion Kids (https://web.fibion.com/kids/) - Activity tracking designed for children. --- Explore our Wearables (https://web.fibion.com/articles/category/wearables/), Experience sampling method (ESM) (https://web.fibion.com/articles/category/experience-sampling-method/), Sleep, (https://web.fibion.com/articles/category/physical-behaviours/sleep/) Heart rate variability (https://web.fibion.com/articles/category/wearables/heart-rate-variability/) (HRV), Sedentary Behavior (https://web.fibion.com/articles/category/physical-behaviours/sedentary-behavior/)and Physical Activity article collection (https://web.fibion.com/articles/category/physical-behaviours/physical-activity/)s for insights on related articles. --- Refer to our article &quot;Physical Activity and Sedentary Behavior Measurements&quot; (https://web.fibion.com/articles/sedentary-behavior-physical-activity-measurements/) for an exploration of active and sedentary lifestyle assessment methods. --- Learn about actigraphy in our guide: Exploring Actigraphy in Scientific Research: A Comprehensive Guide (https://web.fibion.com/articles/actigraphy-scientific-research-guide/). --- Gain foundational ESM insights with &quot;Introduction to Experience Sampling Method (ESM) (https://web.fibion.com/articles/experience-sampling-method-guide-2023)&quot; for a comprehensive overview. --- Explore accelerometer use in health research with our article &quot;Measuring Physical Activity and Sedentary Behavior with Accelerometers &quot; (https://web.fibion.com/articles/accelerometer-measuring-physical-activity-sedentary-behavior/). --- For an introduction to the fundamental aspects of HRV, consider revisiting our Ultimate Guide to Heart Rate Variability (https://web.fibion.com/articles/understanding-heart-rate-variability-hrv-guide). --- Follow the podcast on Twitter <a href="https://

   Improving Daily Well-being Through Better Sleep – Jin Wen (Pt1)

   &quot;What if your sleep quality shapes not just your day, but your whole health future?&quot; In this first episode, Dr. Olli Tikkanen speaks with sleep expert Jin Wen about the fascinating relationship between sleep, stress, and daily well-being. Jin shares her journey from studying stress to focusing on sleep and explains how sleep isn&rsquo;t just about the number of hours you get&mdash;it&#39;s about how you feel when you wake up. Drawing on her research, Jin explores the &ldquo;vicious cycle&rdquo; of daily stress and poor sleep, showing how one bad night can make it harder to handle stress the next day, trapping people in a cycle of fatigue and anxiety. Jin also explains the power of subjective sleep assessments, emphasizing that how you perceive your sleep can be as important as the objective data from sleep trackers. She breaks down her research methods, including the use of ecological momentary assessments (EMA), which capture real-time data about participants&rsquo; daily experiences. This episode is a must-listen for anyone interested in understanding how sleep influences daily functioning and long-term health. --- This podcast episode is sponsored by Fibion (https://web.fibion.com/) Inc. | Better Sleep, Sedentary Behavior and Physical Activity Research with Less Hassle --- Collect, store and manage SB and PA data easily and remotely - Discover ground-breaking Fibion SENS (https://web.fibion.com/sens/). --- SB and PA measurements, analysis, and feedback made easy - Learn more about Fibion Research (https://web.fibion.com/research/). --- Learn more about Fibion Sleep (https://web.fibion.com/sleep/) and Fibion Circadian (https://web.fibion.com/circadian/) Rhythm Solutions. --- Fibion Kids (https://web.fibion.com/kids/) - Activity tracking designed for children. --- Explore our Wearables (https://web.fibion.com/articles/category/wearables/), Experience sampling method (ESM) (https://web.fibion.com/articles/category/experience-sampling-method/), Sleep, (https://web.fibion.com/articles/category/physical-behaviours/sleep/) Heart rate variability (https://web.fibion.com/articles/category/wearables/heart-rate-variability/) (HRV), Sedentary Behavior (https://web.fibion.com/articles/category/physical-behaviours/sedentary-behavior/)and Physical Activity article collection (https://web.fibion.com/articles/category/physical-behaviours/physical-activity/)s for insights on related articles. --- Refer to our article &quot;Physical Activity and Sedentary Behavior Measurements&quot; (https://web.fibion.com/articles/sedentary-behavior-physical-activity-measurements/) for an exploration of active and sedentary lifestyle assessment methods. --- Learn about actigraphy in our guide: Exploring Actigraphy in Scientific Research: A Comprehensive Guide (https://web.fibion.com/articles/actigraphy-scientific-research-guide/). --- Gain foundational ESM insights with &quot;Introduction to Experience Sampling Method (ESM) (https://web.fibion.com/articles/experience-sampling-method-guide-2023)&quot; for a comprehensive overview. --- Explore accelerometer use in health research with our article &quot;Measuring Physical Activity and Sedentary Behavior with Accelerometers &quot; (https://web.fibion.com/articles/accelerometer-measuring-physical-activity-sedentary-behavior/). --- For an introduction to the fundamental aspects of HRV, consider revisiting our Ultimate Guide to Hear
