Core Viewpoint - The article discusses the inaccuracies of stress measurement by smartwatches and apps, emphasizing that the heart rate variability (HRV) used to gauge stress does not solely reflect psychological pressure but also includes various physiological factors [19][32][52]. Group 1: Measurement Methodology - Smartwatches typically measure stress through heart rate variability (HRV), which indicates the variation in time between heartbeats [19][30]. - A healthy heart rate shows variability, while a consistent rhythm indicates lower HRV, suggesting higher stress levels [20][28]. - The autonomic nervous system, comprising the sympathetic (SNS) and parasympathetic (PNS) systems, regulates heart rate and can influence HRV based on various stimuli [22][25]. Group 2: Factors Affecting HRV - Both psychological and physiological stressors can lower HRV, including caffeine intake, smoking, intense exercise, and emotional excitement [34][35][42]. - The smartwatch cannot differentiate between types of stress, leading to potential misinterpretations of the user's actual stress state [44][52]. Group 3: Research Findings - A study involving 781 students found a significant mismatch between smartwatch-measured stress and self-reported stress levels, indicating that wearable device data may not accurately reflect user experiences [46][49]. - The research concluded that wearable device data and self-reported data might represent different concepts, highlighting the limitations of current stress measurement technologies [50][51]. Group 4: User Perception and Misunderstanding - Many users may misinterpret the capabilities of stress-monitoring apps, believing they can accurately assess psychological pressure when they primarily reflect physiological load [56][62]. - The article suggests that while these apps can provide some value, they should not be relied upon for precise psychological assessments [59][65].

Core Viewpoint - Exercise addiction is becoming increasingly common among fitness enthusiasts, characterized by a compulsive need to work out despite potential negative consequences on physical and mental health [5][17][22]. Group 1: Understanding Exercise Addiction - Exercise addiction can be categorized into positive and negative forms, where positive addiction fosters a healthy lifestyle and social connections, while negative addiction can lead to injuries and eating disorders [4][8]. - The prevalence of exercise addiction among regular exercisers is estimated at 3% to 7%, with higher rates among athletes and fitness enthusiasts [5][18]. - Factors such as the use of smart fitness devices and online fitness platforms contribute to the rise of exercise addiction by promoting competition and data tracking [6][21]. Group 2: Psychological Aspects - Exercise addiction is often a response to emotional distress, particularly among younger individuals facing work-related pressures [7][27]. - A significant percentage of individuals with eating disorders also experience exercise addiction, indicating a correlation between the two [8][34]. - The need for emotional release through intense workouts is prevalent, with high-intensity group classes being particularly popular for stress relief [27][28]. Group 3: Implications and Recommendations - The negative aspects of exercise addiction can lead to a vicious cycle of overtraining and dissatisfaction with physical results, potentially resulting in further psychological issues [24][37]. - To mitigate the risks associated with exercise addiction, it is recommended to set realistic fitness goals, incorporate varied exercise types, and seek professional help if necessary [40].

Core Viewpoint - The research reveals a new mechanism by which psychological stress promotes pancreatic cancer through ALKBH5 deficiency and RNA transfer via extracellular vesicles, suggesting potential therapeutic strategies [3][9]. Group 1: Mechanism of Psychological Stress in Pancreatic Cancer - Psychological stress induces ALKBH5 deficiency, which leads to abnormal m6A modifications in RNA, promoting tumor innervation and progression of pancreatic ductal adenocarcinoma (PDAC) [3][6]. - The study demonstrates that pain perception and other stressors activate sympathetic nerves to release norepinephrine, downregulating ALKBH5 in tumor cells [6][9]. Group 2: Clinical Correlation and Potential Treatment - In PDAC patients, ALKBH5 levels are negatively correlated with tumor innervation and patient survival time [7]. - A natural flavonoid compound, fisetin, has been identified to inhibit neuronal uptake of extracellular vesicles carrying m6A-modified RNA, thereby suppressing excessive tumor innervation and cancer progression [7][9].
