"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.---

"Does poor sleep impact your stress more than stress affects your sleep?" 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's response to stress and sleep quality. If you'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.

/Highlights/ Improving Daily Well-being Through Better Sleep – Jin Wen (Pt1)
Monday Sep 08, 2025
Monday Sep 08, 2025
"What if your sleep quality shapes not just your day, but your whole health future?" 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’t just about the number of hours you get—it's about how you feel when you wake up. Drawing on her research, Jin explores the “vicious cycle” 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’ daily experiences. This episode is a must-listen for anyone interested in understanding how sleep influences daily functioning and long-term health.

"Can AI predict pain in animals before it's visible?" In this second episode, Dr. Olli Tikkanen continues his engaging discussion with Prof. Suresh Neethirajan, an expert in digital agriculture and animal welfare. Prof. Neethirajan explains how accelerometer data combined with AI models is being used to detect early signs of pain and health issues in farm animals. By analyzing movement, posture, and other subtle behavioral changes, the AI models can predict conditions like lameness weeks before they manifest. This allows farmers to take preventive action, improving both animal welfare and farm efficiency.
The conversation also highlights how the Fibion SENS system plays a critical role in gathering high-resolution data from larger farm animals. Prof. Neethirajan discusses the balance between data collection frequency and practicality, explaining how wearable sensors and video analytics are evolving to create more efficient, non-invasive monitoring systems for both large and small animals. This episode offers valuable insights into the future of animal welfare and technology's role in improving farm management.

In the third part of the "Physical Activity Researcher Podcast" with Dr. Sebastian Ludyga, the conversation deepens into specific studies and practical applications of physical activity in educational settings. Dr. Ludyga and host Dr. Olli Tikkanen explore the concept of exercise breaks in schools, particularly focusing on how these can rejuvenate students' cognitive resources during a school day.
Dr. Ludyga shares insights from his research on the acute effects of physical activity on school-aged children. He discusses the potential of integrating structured exercise breaks into the school curriculum to enhance cognitive performance temporarily, providing a brief yet potent boost to students' attention and information processing abilities. The discussion also touches on the physiological mechanisms behind these effects, such as the release of hormones and the reallocation of attentional resources, which support cognitive rejuvenation.
Additionally, the episode delves into the broader implications of sedentary behavior, contrasting it with the cognitive benefits derived from active breaks. Dr. Ludyga points out the importance of not just any activity, but structured exercise that involves some intensity, to trigger beneficial brain responses. This nuanced approach offers valuable insights for educators and policy makers interested in fostering environments that support cognitive health through physical activity.
This segment of the podcast provides a comprehensive look at how short bursts of physical activity can be strategically utilized within educational settings to enhance learning and mental performance, making it a must-listen for anyone involved in education, cognitive research, or child development.

"What practical challenges arise in measuring physical activity among children?" In this final part of the episode, Dr. Olli Tikkanen and Dr. Ying Gao discuss the real-world challenges faced when collecting physical activity data from children using devices like Fibion. Dr. Gao shares her experience with device placement, tape sensitivity, and device retention, revealing that around 15-20% of devices were lost in initial studies due to a lack of clear instructions for parents and children. By enhancing communication with parents and teachers and providing practical solutions like custom-made pockets in shorts, Dr. Gao’s team significantly improved data retention and device return rates.
Dr. Gao also highlights how varying humidity levels in different locations impact device attachment and shares strategies, such as using specific tapes and providing flexible study schedules, to make participation easier for children. This episode is essential for researchers looking to understand the logistical considerations in physical activity data collection among young participants.

"How does physical activity differ between children with different body weights?" In this third part of the episode, Dr. Olli Tikkanen and Dr. Ying Gao discuss her findings on physical activity patterns in children, focusing on differences between overweight and normal-weight groups. Dr. Gao explains how accelerometer and EMG data revealed that overweight children show higher muscle activity even when standing, which may contribute to their tendency for more sedentary behavior, as physical tasks can be more exhausting for them. Her research highlights the potential role of physical demands in shaping activity levels among children.
Dr. Gao also shares insights from her 7-day measurement study of over 400 children, examining how physical activity, sedentary behavior, and sleep patterns impact body weight and overall health. The episode touches on future research directions and how these findings could inform interventions to promote healthy behaviors in school-aged children.
