Dizziness is a broad term used to describe sensations of unsteadiness, lightheadedness, disorientation or feeling faint.
It can feel as though the world is moving, the ground is shifting, or the body is struggling to maintain its balance. Some people describe feeling detached from their surroundings, as though they are floating or walking on an unstable surface.
Dizziness can occur in different forms, including:
Lightheadedness: Feeling faint, woozy or as though you might pass out.
Vertigo: A sensation that you or your surroundings are spinning or moving.
Disequilibrium: Feeling unsteady or off-balance, particularly when standing or walking.
Non-spinning dizziness: A sensation of rocking, swaying, floating or internal movement without actual spinning.
Dizziness can be brief and occasional or persistent and disruptive. It is experienced across a range of conditions, including vestibular disorders, migraine, dysautonomia, ME/CFS, Long COVID and other chronic illnesses.

The body's sense of balance relies on information from several interconnected systems.
The vestibular system: Located in the inner ear, this system detects head movement, rotation and changes in position.
Vision: The eyes provide information about the surrounding environment and help the brain understand movement and spatial orientation.
Proprioception: Sensory information from muscles and joints helps the brain understand where the body is positioned.
The autonomic nervous system: Regulates automatic functions such as heart rate and blood pressure, which can influence sensations of lightheadedness and faintness.
The brain combines information from these systems to maintain balance and orientation.
Dizziness can occur when these signals conflict, when the brain processes them differently or when changes in circulation affect how someone feels.
For example, a person may feel unsteady in a busy supermarket because of the amount of visual movement around them, while someone else may experience lightheadedness when moving from sitting to standing.

The brain and nervous system are also involved in detecting potential threats and preparing the body to respond.
When the brain perceives danger, the body's stress response can activate, sometimes described as entering fight, flight or freeze mode.
This can involve changes in breathing, heart rate, muscle tension, attention and sensory processing.
These physical changes can contribute to sensations of dizziness or lightheadedness. For example, rapid or altered breathing can change carbon dioxide levels in the blood, producing sensations of faintness, tingling or unreality.
During periods of heightened stress, the brain may also become more sensitive to bodily sensations and environmental movement.
For some people, this heightened state of alertness can persist beyond an immediate stressful situation, sometimes described as being stuck in survival mode.
Hypervigilance and the Brain's Threat Response
Hypervigilance describes a state of increased alertness to potential danger, including sensations within the body.
When someone experiences repeated episodes of dizziness, the brain may begin monitoring balance and movement more closely.
Sensations that would ordinarily pass unnoticed can become more prominent, and environments associated with previous dizziness may begin to trigger anticipation or anxiety.
This can create a feedback loop in which dizziness increases vigilance, and heightened vigilance amplifies the experience of dizziness.
This interaction is particularly relevant to conditions such as Persistent Postural-Perceptual Dizziness (PPPD), where changes in balance processing, visual dependence and threat-related attention can contribute to persistent symptoms.
Stress, Emotions and Physical Symptoms
Emotional experiences and physical sensations are closely connected through the brain and autonomic nervous system.
Stress, anxiety, grief, anger and other intense emotions can influence breathing, muscle tension, circulation and sensory awareness.
Some mind-body approaches also explore whether emotional suppression or unresolved emotional experiences may contribute to prolonged physiological stress responses.
For example, someone who has spent a long time suppressing difficult feelings or remaining highly alert to their environment may experience persistent muscle tension or heightened sensitivity to bodily sensations.
However, the relationship between emotional suppression and dizziness is complex. There is not sufficient evidence to conclude that repressed emotions are a direct cause of persistent dizziness, and these experiences are not universal.
Importantly, dizziness associated with stress or emotional processes is still a genuine physical experience. It is not imagined or consciously created.
The Interaction Between Brain and Body
The brain continuously interprets information from the body and surrounding environment to create a sense of balance, movement and safety.
Previous experiences, expectations, emotional state and sensory information can all influence this process.
This helps explain why dizziness may fluctuate in different environments or during periods of stress, even when someone is not consciously feeling anxious.
It also explains why physical, neurological and psychological factors can interact rather than operating as entirely separate causes.

Dizziness doesn't always involve spinning.
Although vertigo is often associated with dizziness, many people experience rocking, swaying, floating, tilting or a general sense of instability instead.
It can occur even when sitting or lying down.
Some people experience dizziness without moving, including sensations of internal motion or feeling as though the bed or floor is shifting.
Visual environments can influence symptoms.
Busy patterns, scrolling screens, supermarkets, crowds and moving traffic can be associated with increased dizziness or disorientation.
Dizziness and lightheadedness aren't quite the same thing.
Lightheadedness often involves feeling faint or close to losing consciousness, whereas dizziness can also describe disturbances in balance, movement and spatial orientation.
Stress can influence dizziness without someone feeling anxious.
The body's stress response can involve automatic physiological changes, meaning someone may experience dizziness associated with heightened arousal without consciously recognising fear or anxiety.
It can be accompanied by other symptoms.
Nausea, headaches, fatigue, palpitations, blurred vision, sensitivity to movement and difficulties concentrating can occur alongside dizziness.
The experience can be invisible.
Someone may appear physically steady while experiencing significant sensations of movement, instability or disorientation.

Dizziness can affect far more than physical balance.
The supermarket effect: Feeling overwhelmed or disoriented by shelves, lighting, movement and visual information.
The floating sensation: Feeling disconnected from the ground or as though the body is moving independently of its surroundings.
The sudden wave: Experiencing an unexpected rush of dizziness or lightheadedness during an otherwise ordinary activity.
The moving floor: Feeling as though the ground is tilting, bouncing or shifting beneath your feet.
The concentration struggle: Finding reading, conversations or screen-based tasks more difficult when dizziness is present.
The stress connection: Noticing that dizziness becomes more prominent during emotionally demanding periods, even without consciously feeling anxious.
The invisible effort: Appearing steady and composed while concentrating intensely on maintaining balance or orientation.
For some people, dizziness is a relatively minor background sensation. For others, it can affect mobility, confidence, work, social interaction and everyday independence.
Symptoms may fluctuate throughout the day or change in response to movement, environments, fatigue, stress and other factors.

Dizziness and lightheadedness can occur for many reasons, including inner-ear conditions, migraine, changes in blood pressure, medication effects and other health conditions.
New, persistent, worsening or unexplained dizziness may warrant medical assessment, particularly when it interferes with everyday activities.
Sudden dizziness accompanied by symptoms such as difficulty speaking, facial drooping, one-sided weakness, severe new headache, chest pain or loss of consciousness may indicate a medical emergency.
