What is Stress in Psychology?

In psychology, stress is defined as the body’s response to any demand or challenge that disrupts an individual’s normal equilibrium or state of balance. It’s essentially how the brain and body respond to any demand, not just negative events like trauma or tragedy, but also positive changes like a promotion or a new relationship.

Stress involves a complex interaction between the mind and body. When faced with a challenging situation, the body releases stress hormones like adrenaline and cortisol. This response increases heart rate, elevates blood pressure, and boosts energy supplies. While this can be beneficial in the short term, helping to handle potentially threatening circumstances, chronic stress can lead to significant health issues.

Dealing with stress means finding a way to coexist, not completely eliminate it.

Stress in psychology is typically categorized into two types:

  • Eustress: The ‘positive stress’, the kind of stress that motivates and focuses energy, like the excitement before a big event or the pressure that leads to productivity.
  • Distress: The ‘negative stress’, the kind of chronic, unrelenting stress that feels overwhelming and unmanageable, leading to burnout, health problems, and decreased performance.

Psychologically speaking, stress is also linked to perception. How an individual perceives a situation greatly influences whether the situation will be experienced as stressful. Therefore, psychological interventions often focus on changing perceptions and responses to potentially stressful situations, alongside promoting relaxation and stress-reducing behaviors.

The Impacts of Stress

Stress is complex. When it becomes chronic, its impact can be far-reaching and affect various aspects of one’s life. Here are some key areas where stress can have the most significant effect:

  • Physical Health: Increased risk of heart disease, hypertension, and diabetes. Stress can also cause headaches, muscle tension or pain, fatigue, and upset stomach. Over time, it can weaken the immune system, making the body more susceptible to infections and illnesses.
  • Mental Health: Prolonged stress is a major contributor to mental health issues such as anxiety and depression.
  • Cognitive Functioning: Stress can lead to problems with memory, concentration, and decision-making. It can result in decreased productivity and effectiveness at work or school and can impair judgment and decision-making abilities.
  • Emotional Well-being: High-stress levels can cause emotional symptoms such as irritability, frustration, moodiness, and a feeling of being overwhelmed. It can lead to emotional exhaustion or numbness.
  • Behavioral Changes: Stress in psychology can lead to changes in behavior, such as increased use of alcohol, drugs, or tobacco, changes in sleep patterns, and eating disorders (either overeating or not eating enough). It can also result in social withdrawal and reduced engagement in previously enjoyable activities.
  • Relationships: Stress can strain personal and professional relationships. It can lead to increased conflict, reduced communication quality, and difficulties in maintaining healthy and supportive relationships.
  • Work Performance: In the workplace, stress can reduce the ability to focus and the sense of engagement, lowering productivity.
  • Long-term Implications: Over the long term, chronic stress can contribute to serious health conditions like stroke, obesity, and mental illnesses, and can significantly affect life expectancy.
