Despite these benefits, there is emerging evidence to suggest the temperature of the water exposure can influence energy intake in the subsequent hours. The study aim was to investigate the influence of water temperature on energy expenditure and post-water immersion <em>ad-libitum</em> energy intake in resting adults. Participants with a range of body masses, but otherwise healthy and physically active males (n = 10) and females (n = 5), participated in three randomised trials in a repeated measures crossover design, with a minimum of 7-days apart. Participants were immersed to sternum level for 30-minutes in either cold-water (16 °C), thermoneutral-water (35 °C) or a no-water thermoneutral ambient air control (26 °C). Participants completed appetite related visual analogue scales throughout and were presented with an <em>ad-libitum</em> homogenous pasta meal and asked to eat until ‘comfortably full’.</div></div><div><h3>Results</h3><div>Repeated measures ANOVA showed participants consumed more energy after immersion in cold-water (2783 ± 909 kJ) versus both thermoneutral-water (1817 ± 862 kJ) and thermoneutral ambient air (1894 ± 233 kJ). There were no differences in any of the appetite VAS. Core temperature remained stable throughout the 30 min immersion period across trials, however an after-drop in core temperature was observed for 15 mins following cold-water immersion when compared to both thermoneutral water (P &lt; 0.001), and thermoneutral air (P = 0.004). Although the exact mechanisms are yet to be elucidated, further research is required to identify if the after-drop in core temperature is a potential mechanism responsible for compensatory food intake post cold-water immersion.</div></div><div><h3>Conclusion</h3><div>When presented with an <em>ad-libitum</em> meal directly after cold-water immersion, participants consumed more in comparison to both thermoneutral water immersion and thermoneutral ambient air.

While previous studies have demonstrated the importance of autonomic nervous system (ANS) in emotional processing, the relationship between resting ANS activity and approach-avoidance responses to emotional faces remains unclear. This study investigated how resting autonomic nervous activity measured by skin conductance level (SCL) relates to approach-avoidance decisions in response to facial expressions. After recording resting SCL, participants performed an approach-avoidance task (AAT) with emotional facial stimuli. The task required either approaching happy faces while avoiding angry faces (value-congruent condition) or the opposite pattern (value-incongruent condition). Reaction times (RTs) were significantly faster in value-congruent conditions compared to value-incongruent conditions. The resting SCL showed a significant correlation with the congruency effect (RT difference between conditions). These findings suggest that resting autonomic states, particularly sympathetic arousal, may contribute to the efficiency of approach-avoidance responses. Higher sympathetic activity at rest predicted more efficient responses to emotional faces, potentially reflecting enhanced action readiness. These results extend previous findings on ANS involvement in emotional processing to the domain of approach-avoidance responses to social stimuli, highlighting the role of physiological states in adaptive social behaviour.</div></div>","PeriodicalId":20201,"journal":{"name":"Physiology & Behavior","volume":"295 ","pages":"Article 114912"},"PeriodicalIF":2.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dietary factors and energy state have a profound influence on hippocampal function, and the hippocampus is critical for appropriate behavioral responses associated with feeding and internal hunger cues (being in the fasted or full state), but how the hippocampus senses periprandial status and is impacted by diet is largely unknown. Periprandial hormones act within the hippocampus to modulate processes involved in hippocampal-dependent learning and memory function and astrocytes likely play an important role in modulating this signaling. In addition to periprandial hormones, astrocytes are positioned to respond to changes in circulating nutrients like glucose. Here, we review literature investigating how astrocytes mediate changes in hippocampal function, highlighting astrocyte location, morphology, and function in the context of integrating glucose metabolism, neuroendocrine hormone action, and/or cognitive function in the hippocampus. Specifically, we discuss research findings on the effects of insulin, ghrelin, leptin, and GLP-1 on glucose homeostasis, neural activity, astrocyte function, and behavior in the hippocampus. Because obesogenic diets impact neuroendocrine hormones, astrocytes, and cognitive function, we also discuss the effects of diet and diet-induced obesity on these parameters.</div></div>","PeriodicalId":20201,"journal":{"name":"Physiology & Behavior","volume":"295 ","pages":"Article 114913"},"PeriodicalIF":2.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many individuals overeat in response to stressors, yet others decrease or do not change their food intake. Individual differences in factors related to stress and eating, such as stress mindset (i.e., perceptions regarding the nature of stress), may explain this variability in stress-eating. To investigate, we conducted the present pre-registered study, where we investigated whether stress mindset, 1) predicted psychophysiological stress responses, 2) predicted snack intake post-stress, and 3) moderated the stress-eating relationship. Participants were 86 women (34 % non-White) between 18 and 22 years old, with a mean body mass index of 24 kg/m^2, who completed two visits. Participants completed an assessment of stress mindset during a preliminary screening and, on a subsequent laboratory visit, underwent a stress mindset manipulation followed by an acute social stress task (i.e., TSST) and a snack food taste test. Greater stress-is-enhancing mindsets during screening predicted more adaptive stress responses (greater ratio of sympathetic markers to cortisol levels) and healthier post-stress eating behaviors. Furthermore, the moderation model (PROCESS model 1) was significant: greater post-stress negative affect was associated with more M&amp;M intake only for women with greater stress-is-debilitating mindsets at screening, and greater heart rate was associated with less chip and veggie straw intake only for women with greater stress-is-enhancing mindsets at screening. Thus, stronger stress-is-enhancing mindsets may reduce the impact of psychophysiological stress responses on snack food intake for women. Replications in larger and more diverse samples may elucidate the mechanisms underlying the moderation and inform eating- and obesity-related treatments targeting stress mindset.</div></div>","PeriodicalId":20201,"journal":{"name":"Physiology & Behavior","volume":"296 ","pages":"Article 114910"},"PeriodicalIF":2.4,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study validates IRT in wild crested macaques (<em>Macaca nigra</em>), observed in their natural habitat, to assess its potential for studying short-term emotions as proximate mechanisms of behavior of wild animals. Seventy-five playback experiments and predator model presentations were conducted on 14 adult females, exposing them to stimuli including affiliative grunts, contact calls, aggressive screams, alarm calls, and python models. The objectives were to: (1) evaluate whether environmental and physical factors, such as atmospheric conditions and camera-subject distance, impact thermal measurements; (2) determine whether facial skin temperature variations reliably indicate emotional arousal and valence in response to ecologically relevant stimuli; and (3) explore correlations between temperature changes and behavioral indicators of arousal, such as physical activity and self-directed behaviors. Results showed that: (1) environmental and physical factors did not significantly affect thermal measurements when following our protocol; (2) facial skin temperature changes reliably reflected the intensity of emotional arousal elicited by different stimuli; and (3) temperature variation was associated with behavioral indicators of arousal and anxiety.
