Article Abstract
Background: Definitive knowledge of the 24-hour cardiac autonomic activity in patients with allergic rhinitis (AR) is lacking. Thus, we aimed to evaluate heart rate variability (HRV), which is used to measure cardiac autonomic activity by 24-hour Holter monitoring in patients with AR.
Methods: We enrolled 32 patients who visited our clinic and were diagnosed with AR. The control group was selected four-fold (n = 128) by matching (age, sex, hypertension, and diabetes) in the AR group from a Holter registry in the cardiology department. The HRV results, which were measured using 24-hour Holter monitoring, were compared between the AR and control groups.
Results: All time-domain parameters of HRV revealed no differences between the groups. However, among the frequency domain parameters of HRV, the low-frequency to high-frequency ratio and low-frequency power in normalized units were significantly lower in the AR group. Conversely, high-frequency power in normalized units was significantly higher in the AR group. In the multiple regression analysis, AR was independently associated with sympathetic withdrawal (adjusted odds ratio = 3.393, = 0.020) after adjusting for age, sex, hypertension, diabetes mellitus, and hyperlipidemia.
Conclusions: The present findings suggest differences in cardiac autonomic activity which are related with sympathetic withdrawal in patients with AR compared with that in the normal population over 24 hours.

Salivary cortisol response to post-exercise infrared sauna declines over time.

Heat exposure after exercise may enhance recovery of physical performance but can also impose additional physiological stress on athletes. This study investigated the effects of post-exercise infrared sauna (IRS) on adrenal and autonomic nervous system (ANS) responses and examined how these responses adapt over time during a 6-week training intervention. Forty female team-sport athletes were pair-matched into an IRS-group and a control group (CON).

Background: Dissociative disorders frequently co-occur with post-traumatic stress disorder (PTSD), yet many individuals lack adequate treatment. Existing interventions often prioritise reducing arousal over promoting safety and self-soothing, tending to neglect the bodily experience.
Aims: This randomised clinical within-person pilot study examined the effects of the nest position, a physiotherapeutic intervention designed to enhance safety and self-soothing, on patients with dissociative disorders and healthy controls (German Clinical Trials Register No.
A Low Sodium Diet Activates HSD2 Neurons in the Nucleus Tractus Solitarii to Promote Sodium Appetite Via the cAMP/MAPK Signaling Pathway.

Background: Sodium homeostasis is crucial for physiological balance, yet the neurobiological mechanisms underlying sodium appetite remain incompletely understood. The nucleus tractus solitarii (NTS) integrates visceral signals to regulate feeding behaviors, including sodium intake. This study investigated the role of 11β-hydroxysteroid dehydrogenase type 2 (HSD2)-expressing neurons in the NTS in mediating sodium appetite under low-sodium diet (LSD) conditions and elucidated the molecular pathways involved, particularly the cyclic adenosine monophosphate (cAMP)/mitogen-activated protein kinase (MAPK) signaling cascade.

Autonomic medicine is a rapidly evolving field focused on understanding diseases and processes that affect the autonomic nervous system (ANS). The ANS regulates essential involuntary physiologic processes such as heart rate, blood pressure, and digestion. This review introduces the key anatomical structures, physiological mechanisms, and biochemical processes underlying autonomic function.

Background A cold-sensitivity constitution (CSC), termed "Hiesho" in Japanese, is a common condition among young women that impairs quality of life through reduced peripheral circulation and autonomic imbalance. In our previous study, we reported that cold intolerance is associated with an imbalance in autonomic nervous function, as evaluated by heart rate variability (HRV). Conversely, footbathing increases parasympathetic nervous activity (PNA) and increases both peripheral blood flow and epidermal temperature.
