Dizzy from stress: the difference between light-headed and spinning
A floaty, swimmy feeling, worse in shops and on stairs, better when you sit. Not the room spinning — more like the floor has become slightly unreliable, and you have started planning where the handrails are.
Do this now
Small breaths, ninety seconds
2 minute
- Stop still. Fix your eyes on one stationary object at a distance and keep them there.
- Close your mouth. Breathe in small through the nose, out slowly through the nose.
- Keep the breaths deliberately smaller than you want for ninety seconds.
- Do not sit down unless you need to, and do not breathe deeply. Both make the light-headed version worse.
- When it settles, walk on with the mouth closed. Avoiding movement is what makes this spread.
Two different symptoms, one word
Vertigo is the illusion of movement — the room spinning, usually with nausea, often triggered by head position. Light-headedness is a woolly, floaty, about-to-float-away feeling with no rotation. Anxiety and over-breathing produce the second, overwhelmingly. Getting the distinction right matters, because true rotational vertigo points at the inner ear or the brain and has entirely different causes.
Where the light-headedness comes from
Low carbon dioxide from over-breathing constricts cerebral arteries and reduces cerebral blood flow measurably. That produces exactly this sensation, along with visual greying and unreality. It is why the reset is smaller breaths rather than bigger ones, and why sitting down and taking deep breaths — the standard instinct — often prolongs it.
Why it becomes chronic
There is a recognised condition, persistent postural-perceptual dizziness, in which an initial vestibular or anxiety-driven episode is followed by months of non-spinning dizziness that is worse when upright, in motion, or in visually busy environments. It is maintained partly by hypervigilance to balance and by avoidance of movement. The treatment is vestibular rehabilitation and graded exposure to movement — which is the opposite of resting, and worth knowing before a year has passed.
What changes it, over a week
All day
Mouth closed. This does most of the work for the over-breathing half.
Daily
Twenty minutes of walking, including in busy visual environments. Avoiding movement is what turns an episode into a condition.
Twice a day, five minutes
Small nasal breathing at mild air hunger, sitting upright.
Each morning
Control Pause, and note whether the dizzy days are the low-reading days. Usually they are.
When this is not a breathing pattern
See a clinician — promptly, and before assuming any of this applies to you — if any of these describe you:
- True spinning, especially with hearing loss, ringing in one ear, double vision, slurred speech or weakness — seek urgent assessment
- Dizziness with a severe sudden headache, or the worst headache of your life — emergency
- Fainting, or dizziness on exertion or lying down
- Dizziness that started with a new medication, or with blood loss or persistent vomiting
- A large drop in blood pressure or a big rise in heart rate on standing — ask about orthostatic testing

Questions people ask
- How do I know if it is anxiety or my ears?
- The most useful question is whether the room spins. Rotational vertigo, especially with hearing change or triggered by head position, points at the vestibular system. A floaty, non-spinning light-headedness that varies with stress and improves with small breaths fits the breathing pattern.
- Why is it worse in supermarkets?
- Visually busy, brightly lit environments load the balance system, which relies partly on vision. That is a recognised feature of persistent postural-perceptual dizziness and it is also why avoiding those places makes it worse over time.
- Should I stop driving?
- If you have had any episode where you felt unsafe, get assessed before driving again, and follow local rules about reporting. Light-headedness without loss of function is usually not a driving bar, but that is a clinician's call rather than yours or mine.

Put a number on it
Most of what is on this page tracks one measurement: the Control Pause. It takes sixty seconds, needs no account, and it is the thing that tells you whether any of this is working.
