Feeling dizzy after an earthquake—even when the shaking has stopped—is a real medical condition that affects both the body and mind. This condition is known as Post-Earthquake Dizziness Syndrome (PEDS).
What does it feel like?
Many people report symptoms such as:
- A sensation that the ground is still shaking
- Feeling physically unsteady or unstable
- Dizziness or lightheadedness
- Nausea without any clear physical cause
In Japan, this condition is called 地震酔い (Jishin-yoi), which translates to “earthquake drunkenness”—describing the disoriented, seasick-like feeling often experienced after a quake.
Why does it happen?
Although the exact cause isn’t fully understood, researchers believe PEDS is linked to a combination of:
- Inner ear disturbances, as your vestibular system adjusts after prolonged shaking
- Psychological stress and fear of aftershocks
- The brain “remembering” instability, which may trigger physical symptoms
This condition may overlap with Persistent Postural-Perceptual Dizziness (PPPD) or even Post-Traumatic Stress Disorder (PTSD).
Common Symptoms of PEDS:
- Dizziness or vertigo (feeling movement when everything is still)
- Swaying or unsteady walking
- Nausea or mild vomiting
- Difficulty sleeping, feeling unsafe alone
- Increased irritability or anxiety
What should you do?
If you’re experiencing these symptoms after an earthquake, don’t ignore them. A doctor can help rule out other conditions and recommend treatment options, including:
- Vestibular rehabilitation
- Stress and anxiety management
- Medications if needed
Post-earthquake dizziness is real—and treatable. Don’t hesitate to seek medical support.
The Mind-Body Connection
While PEDS can result from physical imbalances in the inner ear, it’s also rooted in psychological stress following traumatic experiences:
- Sudden, violent events like earthquakes can overstimulate the autonomic nervous system, leading to dizziness, heart palpitations, and nausea.
- PEDS can be the starting point for deeper mental health concerns like anxiety, panic attacks, or even post-traumatic stress disorder (PTSD).
- If left unaddressed, it may evolve into long-term mental health issues.
When to Seek Medical Attention
General medical symptoms that require attention include:
- Dizziness that makes it hard to stand or walk
- Persistent nausea and vomiting
- Double vision or slurred speech
- Symptoms occurring alongside heart disease, high blood pressure, or diabetes
Psychiatric or psychological symptoms that need professional care:
- Constant fear or excessive anxiety
- Nightmares, flashbacks, or waking up in panic
- Avoiding places linked to the earthquake
- Physical symptoms of stress (e.g., sweating, chest tightness, shortness of breath)
- Worsening of existing mental health conditions like depression or anxiety
Basic Self-Care Tips
- Prioritize adequate sleep and rest
- Limit exposure to earthquake-related news or videos
- Practice deep breathing exercises
- Stay in environments where you feel safe and calm
- Seek medical advice for lingering dizziness or stress-related symptoms—medications or therapy may help
A Message to Those Affected
PEDS is not a sign of weakness, nor is it “just overthinking.” It’s a legitimate condition that responds well to proper medical and psychological care.
With the right support, most symptoms improve within 1–2 weeks. If the symptoms interfere with daily life, don’t hesitate to consult a doctor or mental health professional.
