Mindra Haus Understanding stress starts with understanding the language used to describe it.
Here you’ll find simple explanations of key terms related to stress, the nervous system, regulation, resilience, and how the body responds to pressure.
Acute Stress
Acute stress is the body’s short-term response to an immediate challenge, pressure, or perceived threat.
It activates systems that increase alertness and prepare the body to respond. When the challenge passes, the body can usually return towards its normal state.

- Stress Response
- Adrenaline
Adaptation
Adaptation is the process of adjusting to changes, challenges, or repeated experiences.
The body and brain constantly adapt to demands from the environment, helping us learn, cope, and respond effectively.

- Recovery
- Stress Response
Autonomic Nervous System
The autonomic nervous system controls many automatic functions that happen without conscious effort.
It regulates processes such as heart rate, breathing, digestion, and stress responses.
It includes the sympathetic and parasympathetic nervous systems.

Chronic Stress
Chronic stress refers to a prolonged stress response that continues over an extended period.
Unlike short-term stress, which can help the body respond to immediate challenges, ongoing stress can place continued demands on the body and may affect sleep, energy, mood, focus, and overall wellbeing.

Coping
Coping refers to the ways people manage challenges, stress, or difficult experiences.
Coping strategies can involve thoughts, emotions, behaviours, routines, and support systems.

- Resilience
- Self-Regulation
- Emotional Regulation
Cortisol
Cortisol is a hormone involved in the body’s stress response.
It helps regulate energy, metabolism, immune activity, and the body’s response to challenges. Cortisol is not simply a “bad” hormone — it has important normal functions.

- Stress Hormones
- Stress Response
Emotional Regulation
Emotional regulation is the ability to recognise, manage, and respond to emotions.
It does not mean removing emotions, but being able to respond in ways that support wellbeing and decision-making.

- Self-Regulation
- Resilience
- Coping
Fight-or-Flight Response
The fight-or-flight response is the body’s automatic survival response to a perceived threat.
It activates the nervous system and stress hormones to prepare the body for action.

- Sympathetic Nervous System
- Adrenaline
- Stress Response
HPA Axis
The HPA axis is a communication system involving the hypothalamus, pituitary gland, and adrenal glands.
When the brain detects stress, the hypothalamus signals the pituitary gland, which then signals the adrenal glands to release hormones such as cortisol.
The HPA axis helps regulate the stress response, energy use, and adaptation.

- Cortisol
- Stress Response
- Stress Hormones
Nervous System
The nervous system is the body’s communication network.
It uses electrical and chemical signals to coordinate movement, thoughts, sensations, emotions, and automatic body functions.

- Brain
- Autonomic Nervous System
- Nervous System Regulation
Nervous System Regulation
Nervous system regulation refers to the body’s ability to adjust between states of activation and recovery.
It helps the body respond to demands while also allowing periods of rest, repair, and restoration.
Related:
- Stress Response
- Parasympathetic Nervous System
- Recovery
Noradrenaline
Noradrenaline is a chemical messenger involved in alertness, attention, and the stress response.
It helps increase focus and prepares the body to respond to changing situations.
Related:
- Adrenaline
- Stress Hormones
- Nervous System
Parasympathetic Nervous System
The parasympathetic nervous system is part of the autonomic nervous system.
It supports recovery processes such as slowing heart rate, supporting digestion, and helping the body return towards balance after stress.
Related:
- Rest-and-Digest Response
- Autonomic Nervous System
- Recovery
Regulation
Regulation refers to the processes that help the body maintain balance and adjust to changes.
It applies to systems including stress responses, emotions, energy, and internal body processes.
Related:
- Homeostasis
- Self-Regulation
- Adaptation
Resilience
Resilience refers to the ability to adapt to challenges and recover after stress.
It is influenced by biology, experiences, habits, environment, and support systems.
Related:
- Adaptation
- Coping
- Stress Response
Rest-and-Digest Response
The rest-and-digest response describes the body’s recovery state.
It is linked to parasympathetic nervous system activity and supports processes such as digestion, restoration, and recovery.

- Recovery
- Regulation
Self-Regulation
Self-regulation is the ability to manage thoughts, emotions, and behaviours.
It helps with decision-making, behaviour change, emotional responses, and adapting to challenges.

- Emotional Regulation
- Coping
- Behaviour Change
Stress
Stress is the body’s response to demands, challenges, or perceived threats.
It involves interactions between the brain, nervous system, hormones, and body systems. Stress can be helpful in short periods but become difficult when prolonged.
Related:
- Stress Response
- Chronic Stress
- Cortisol
Stress Hormones
Stress hormones are chemical messengers involved in the body’s response to challenges.
They help coordinate changes in energy, alertness, and physiological responses. Examples include cortisol and adrenaline.
Related:
- Cortisol
- Adrenaline
- HPA Axis
Stress Response
The stress response is the body’s coordinated reaction to a challenge or perceived threat.
It involves the nervous system, hormones, and changes in the body that help us respond and adapt.
Related:
- Fight-or-Flight Response
- HPA Axis
- Cortisol
Sympathetic Nervous System
The sympathetic nervous system is part of the autonomic nervous system.
It increases alertness and prepares the body for action by influencing heart rate, breathing, and energy availability.
