Highlights:
- Prevalence & Chronicity: Dizziness affected 24.6% of adults, with 17.1% of these experiencing chronic dizziness (≥3 months).
- Psychosocial Factors: Female sex, high levels of stress, and depression were strongly associated with dizziness.
- Chronic Dizziness: Factors contributing to chronic dizziness included tympanic abnormalities, diabetes, short sleep duration, and higher stress and depression levels.
- Depression & Dizziness: Psychomotor retardation/agitation was a central symptom of depression in those with chronic dizziness.
- Sex Differences: The study identified different factors influencing dizziness between men and women, suggesting sex-specific pathophysiological mechanisms.

Major Findings: Psychosocial Factors vs. Dizziness & Chronic Dizziness (2024)
1. Prevalence & Chronicity of Dizziness
Finding: Dizziness is quite common among adults, with 24.6% experiencing it within a year. Chronic dizziness, lasting three months or more, affects 17.1% of those who report dizziness.
Details: Dizziness can disrupt daily activities and lower the quality of life.
In this study, nearly 25% of adults reported dizziness in the past year.
Among these, about one in six suffered from chronic dizziness, indicating it as a persistent issue for many.
Chronic dizziness can stem from various health problems and often leads to significant discomfort and impairment in daily functioning.
2. Influence of Psychosocial Factors
Finding: High levels of stress and depression are closely linked to dizziness.
Details: The study found that individuals experiencing high stress levels or depression are more likely to suffer from dizziness.
Stress and depression can affect the body’s balance system, making people more prone to feeling dizzy.
This highlights the importance of addressing mental health issues as part of the treatment for dizziness.
By managing stress and depression, it might be possible to reduce the frequency and severity of dizziness episodes.
3. Factors Contributing to Chronic Dizziness
Finding: Chronic dizziness is associated with tympanic abnormalities (issues with the ear), diabetes, short sleep duration, and higher levels of stress and depression.
Details: Chronic dizziness, which lasts for at least three months, was found to be more common among people with specific health issues:
- Tympanic Abnormalities: Problems with the ear, such as infections or other ear disorders, can lead to long-term dizziness.
- Diabetes: This condition can cause nerve damage and affect balance, leading to chronic dizziness.
- Short Sleep Duration: Not getting enough sleep, particularly less than five hours a night, can exacerbate dizziness.
- High Stress & Depression: Persistent stress and depression can worsen dizziness, making it more chronic.
4. Depression & Dizziness
Finding: Psychomotor retardation/agitation, a symptom of depression, is a central feature in those with chronic dizziness.
Details: Depression often accompanies chronic dizziness, with specific symptoms like psychomotor retardation (slowed movements) and agitation (restlessness) being particularly prominent.
These symptoms can make managing dizziness more challenging, as they contribute to the overall feeling of instability and imbalance.
Understanding this connection can help in developing better treatment plans that address both dizziness and its associated depressive symptoms.
5. Sex Differences in Dizziness
Finding: There are significant differences between men and women in the factors that contribute to dizziness.
Details: The study identified that women are generally more prone to dizziness than men.
Specific factors that contribute to dizziness also vary between the sexes:
- Women: Smoking and arthritis were found to be significant contributors to dizziness. Smoking can impair blood flow to the inner ear, while arthritis can affect balance due to joint pain and instability.
- Men: Older age, lower education levels, and alcohol consumption were more strongly associated with dizziness. As men age, they may be more susceptible to conditions that affect balance, and lower education levels can be linked to less health awareness and management.
How Psychosocial Factors Modulate Dizziness Risk
1. Stress
Impact: High levels of stress can significantly increase the risk of experiencing dizziness.
Mechanism: Stress affects the body through the release of stress hormones like cortisol, which can alter vestibular function and disrupt balance. Chronic stress may impair the body’s ability to compensate for balance disturbances, leading to increased dizziness.
Example: Individuals under constant stress may experience heightened sensitivity to movement and changes in posture, making them more susceptible to dizziness.
2. Depression
Impact: Depression is closely linked to both episodic and chronic dizziness.
Mechanism: Depression can alter the central nervous system’s processing of sensory information, affecting balance and spatial orientation. Specific depressive symptoms, such as psychomotor retardation (slowed movements) and agitation (restlessness), can exacerbate feelings of dizziness.
Example: A person with depression may find it difficult to maintain balance due to slowed reactions and heightened anxiety, leading to more frequent and severe dizziness episodes.
3. Anxiety
Impact: Anxiety can contribute to the onset and persistence of dizziness.
Mechanism: Anxiety increases the body’s arousal state, which can interfere with the vestibular system and its ability to process balance-related information. This heightened state of arousal can make individuals more aware of and distressed by minor balance disturbances.
Example: Someone with anxiety might feel dizzy in situations that require precise balance control, such as walking in crowded places or standing on a moving vehicle.
4. Sleep Disturbances
Impact: Short sleep duration is linked to an increased risk of chronic dizziness.
Mechanism: Lack of sleep can impair cognitive and physical functions, including those that govern balance and coordination. Sleep deprivation can also heighten stress and anxiety levels, further exacerbating dizziness.
Example: A person who regularly sleeps less than five hours a night may experience chronic dizziness due to the compounded effects of sleep deprivation and increased stress.
Dizziness vs. Psychosocial Factors (2024 Study)
The study aimed to identify psychosocial factors related to dizziness and chronic dizziness in adults, focusing on how these factors contribute to the prevalence and persistence of dizziness.
Sample
The study analyzed data from 4,147 adults aged 40 and above, derived from the Eighth Korea National Health and Nutrition Examination Survey (2020).
Out of these, 1,102 adults who experienced dizziness were included in the dizziness cohort.
Methods
- Design: Population-based cross-sectional study.
- Data Collection: Demographic information, medical conditions, comorbidities, functional status, nutritional intake, and psychological variables were collected through surveys and medical examinations.
- Analysis: Multiple logistic regression was used to identify factors associated with dizziness. Subgroup analysis was conducted based on sex. Network analysis was performed to understand the pattern of depressive symptoms related to dizziness severity.
Limitations
- Cross-Sectional Design: The study design does not allow for conclusions about causal relationships between factors and dizziness.
- Self-Reported Data: Dizziness was assessed through self-reported surveys, which may lead to recall bias and subjective interpretations.
- Lack of Distinction: The study did not differentiate between types of dizziness (e.g., vertigo vs. non-vertiginous dizziness) or types of chronic dizziness, which may affect the specificity of the findings.
Conclusion: Psychosocial Factors vs. Dizziness
This study highlights the significant role that psychosocial factors, including stress, depression, and sleep disturbances, play in modulating the risk and persistence of dizziness and chronic dizziness.
The findings underscore the importance of addressing mental health issues alongside physical health conditions in the management of dizziness.
Specifically, the study suggests that women are more prone to dizziness, with factors like smoking and arthritis contributing significantly, while in men, older age, lower education levels, and alcohol consumption are key contributors.
By identifying these factors, the study provides a comprehensive understanding that can inform more effective, individualized treatment strategies.
Future research should focus on longitudinal studies to establish causal relationships and explore targeted interventions that address both psychosocial and physical health factors to mitigate dizziness and improve patients’ quality of life.
