Psychoneuroimmunology: Cardiovascular Disease

680
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Stress and Mental Health

1.3K
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...

Introduction to Stress and Lifestyle

817
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...

Psychoneuroimmunology: Diabetes and Cancer

634
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Psychological Responses to Stress01:20

Psychological Responses to Stress

886
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Physiological Foundation of Stress01:24

Physiological Foundation of Stress

1.0K
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.
Role of the Sympathetic Nervous System
Adrenaline triggers the...

Area of Science:

  • Psychology
  • Neuroscience
  • Chronobiology

Background:

  • Accurate time perception is crucial, yet stress can alter it.
  • Previous research suggests chronic stress affects time perception in animal models and patients.
  • The impact of chronic stress on time perception in healthy individuals remains largely unexplored.

Purpose of the Study:

  • To investigate the relationship between chronic stress and time perception in healthy young men.
  • To determine if stress levels correlate with temporal sensitivity and subjective duration estimates.

Main Methods:

  • 62 healthy young men completed the Perceived Stress Scale (PSS).
  • Time perception was assessed using a temporal bisection task with visual signals.
  • Participants judged probe durations against short (400 ms) and long (1600 ms) anchors.

Main Results:

  • Higher chronic stress levels were negatively correlated with temporal sensitivity (Weber ratio).
  • No significant correlation was found between chronic stress and subjective duration (bisection point).

Conclusions:

  • Chronic stress is associated with diminished temporal sensitivity in healthy adults.
  • This study provides evidence linking chronic stress to altered time perception in a healthy population.
