Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

49.3K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Therapeutic Communication01:30

Therapeutic Communication

9.0K
Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Cushing Syndrome II: Pathophysiology

58
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features...

Physiological Foundation of Stress01:24

Physiological Foundation of Stress

1.1K
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.

Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

Introduction to Stress and Lifestyle01:27

Introduction to Stress and Lifestyle

879
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Area of Science:

  • Psychology
  • Human-Computer Interaction
  • Endocrinology

Background:

  • Interpersonal touch is crucial for social interaction and stress reduction.
  • Tactile feedback in communication devices aims to replicate touch effects.
  • Objective endocrine effects of device-mediated touch remain largely unstudied.

Purpose of the Study:

  • To investigate if physical contact with a huggable communication device can reduce stress hormone cortisol levels.
  • To compare the endocrine effects of interacting with a huggable device versus a mobile phone.
  • To explore the potential of bio-markers in evaluating communication media.

Main Methods:

  • Participants engaged in 15-minute conversations.
  • Conversations were conducted either with a huggable human-shaped device or a standard mobile phone.
  • Salivary cortisol levels were measured before and after the conversations.

Main Results:

  • A significant reduction in cortisol levels was observed in participants using the huggable device.
  • No significant cortisol reduction was found for participants using the mobile phone.
  • This suggests a physiological stress-mitigating effect of the huggable interface.

Conclusions:

  • Huggable communication devices can elicit measurable physiological stress reduction.
  • This research provides a biological basis for designing supportive communication technologies.
  • Findings support the development of advanced interpersonal communication media for enhanced social support in networked societies.
