Introduction to Stress and Lifestyle01:27

Introduction to Stress and Lifestyle

155
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...

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

82
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Global Climate Change

24.6K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

What is Climate?01:16

What is Climate?

18.7K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Psychological Responses to Stress01:20

Psychological Responses to Stress

86
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...

Area of Science:

  • Psychology
  • Environmental Science
  • Public Health

Background:

  • Climate change poses significant risks, increasing the intensity of extreme weather events like typhoons and cyclones.
  • Understanding public perception of climate change risks is crucial for effective public health and disaster response strategies.

Purpose of the Study:

  • To develop and validate a model of climate change risk perception.
  • To identify key psychological and experiential factors influencing how individuals perceive climate change risks.

Main Methods:

  • Two studies were conducted with survivors of Super Typhoon Haiyan (Philippines) and Cyclone Winston (Fiji).
  • Structural equation modeling was employed to analyze the relationships between variables.
  • Participants completed validated measures of resource loss, posttraumatic stress, coping, social support, posttraumatic growth, and climate change risk perception.

Main Results:

  • The developed climate change risk perception model was validated across both study samples.
  • Key predictors of climate change risk perception included resource loss, posttraumatic stress, coping activation, and posttraumatic growth.
  • Posttraumatic growth emerged as a central factor influencing climate change risk perception.

Conclusions:

  • Public health education should emphasize how climate change impacts life priorities and meaning.
  • Disaster response organizations can leverage this understanding to improve preparedness strategies.
  • Interventions focusing on posttraumatic growth may enhance risk perception and preparedness for climate-related disasters.
