Autonomic cardiac regulation to slow-paced respiration in seated and supine positions Open
These results showed that (1) whatever the slow-paced breathing frequency, slow breathing favours parasympathetic control and slow heart rhythm; and (2) seated position favors autonomic cardiovascular interaction between respiratory modula…

Changes in heartbeat-evoked potentials reflect changes in blood pressure Open
Heartbeat-evoked potentials (HEPs) allow to explore the interaction between cardiovascular and central nervous systems, showing that interoceptive processing may influence cognitive, emotional, and sensorimotor functions. However, the exte…

The effects of acute exercise and a nap on heart rate variability and memory in young sedentary adults Open
Recent evidence suggests that the autonomic nervous system can contribute to memory consolidation during sleep. Whether fluctuations in cardiac autonomic activity during sleep following physical exercise contribute to the process of memory…

View article: A Pilot Randomized Trial of Combined Cognitive-Behavioral Therapy and Exercise Training Versus Exercise Training Alone for the Management of Chronic Insomnia in Obstructive Sleep Apnea
A Pilot Randomized Trial of Combined Cognitive-Behavioral Therapy and Exercise Training Versus Exercise Training Alone for the Management of Chronic Insomnia in Obstructive Sleep Apnea Open
Rationale Among individuals with obstructive sleep apnea, about 38% will present with comorbid chronic insomnia. Comorbid chronic insomnia and obstructive sleep apnea (COMISA) is associated with poorer daytime functioning and increased mor…

Oral Abstract Open
Objectives/Introduction: Previous evidence suggests that night-time insomnia symptoms (i.e., difficulties in sleep onset and sleep maintenance) may be associated with increased peripheral inflammatory markers, which is involved in the path…

Effect of Cognitive-Behavioral Therapy on Nocturnal Autonomic Activity in Patients with Fibromyalgia: A Preliminary Study Open
Objective: fibromyalgia is a complex chronic pain syndrome characterized by widespread musculoskeletal pain, insomnia and autonomic alterations. Cognitive-behavioral therapy (CBT) is regarded as a promising treatment in fibromyalgia, but i…

Insomnia Symptoms, Sleep Hygiene, Mental Health, and Academic Performance in Spanish University Students: A Cross-Sectional Study Open
Background: Insomnia has been associated with decreased academic performance and unhealthy behaviors in university students. Although many studies have analyzed sleep phenomenology among this population, only few have focused on insomnia a…

Psychometric properties of the Spanish version of the Sleep Hygiene Index Open
The Sleep Hygiene Index (SHI) has shown adequate psychometric properties in samples from several countries but has not been validated in Spanish. The aims of the study were to translate the original (i.e., English) version of the SHI into …

Emotion regulation of others’ positive and negative emotions is related to distinct patterns of heart rate variability and situational empathy Open
Although emotion regulation has been proposed to be crucial for empathy, investigations on emotion regulation have been primarily limited to intrapersonal processes, leaving the interpersonal processes of self-regulation rather unexplored.…
