Vertigo or dizziness?
Vertigo is the feeling that you, or everything around you, is spinning, enough to affect your balance. An attack can last from a few seconds to hours, and severe vertigo can last days or months. Dizziness is the wider word: feeling off-balance, giddy, light-headed or faint. Causes of dizziness include ear infections, migraine, dehydration, stress or anxiety, low blood sugar, anaemia and medicines.

How balance works
Your brain combines what your eyes see, signals from sensors in your body, and the balance organ in each inner ear, which signals whenever your head moves. When one part sends faulty signals you feel dizzy, and the brain adjusts, faster when you practise the movements that bring the dizziness on. That's how vestibular rehabilitation works, and yoga doesn't do it on purpose.

Brief spins when you move your head: BPPV
Loose chalk crystals in one of the inner ear's canals cause short spins, usually 5 to 30 seconds, when you lie flat, sit up, turn over in bed, look up or bend down. In a German population study, 2.4% of adults had had it at some point. It's common after a head injury or labyrinthitis. At least half of people get better without treatment, though it may take months, and medicines don't move the crystals.

After an inner-ear infection: labyrinthitis and vestibular neuritis
Usually caused by a virus. Symptoms often ease after a few days and balance usually comes back over 2 to 6 weeks, sometimes longer. The NHS suggests getting out for a walk as soon as you can, with someone at first, and says vestibular rehabilitation for lasting problems should be supervised by a specialist such as a physiotherapist or audiologist.

Attacks with ringing or a full ear: Ménière's disease
Sudden attacks lasting from a few minutes to 24 hours, with spinning, ringing in the ear (tinnitus), hearing loss and a feeling of pressure in the ear. Exercises can't stop the attacks, but they can help the unsteadiness between them, and the NHS says relaxation techniques, such as breathing exercises, can help.

Dizziness with migraine: vestibular migraine
Migraine in which dizziness is the main symptom, in episodes lasting 5 minutes to 72 hours (NICE's description). There's almost no trial evidence for non-drug ways to prevent it. Our yoga for headaches and exercise for migraine guides have more.

Dizzy most days for months: PPPD
Persistent postural-perceptual dizziness (PPPD) means dizziness or unsteadiness on most days for months. A Cochrane review found no trial of rehabilitation that met its standards. Our vertigo exercise guide covers what specialists offer.

Light-headed when you stand up
Dizziness or light-headedness when you stand up or change position can be a drop in blood pressure (postural hypotension), not vertigo. Get up slowly, from lying to sitting to standing, and see a GP if you keep getting dizzy or fainting. Our exercise for PoTS guide covers postural tachycardia syndrome.

Dizziness and the neck
Dizziness coming from the neck (cervicogenic dizziness) is a debated diagnosis, made once other causes are ruled out. Across 13 trials (898 people), hands-on treatment eased it (moderate-quality evidence), more so with exercise (very low quality). Yoga poses for "cervical vertigo" haven't been tested. Our yoga for neck pain guide covers the neck.

Stroke: rare, but an emergency
In 1,666 emergency patients with dizziness, vertigo or imbalance, 3.2% had a stroke or mini-stroke (transient ischaemic attack), and 0.7% of those with dizziness alone. Dizziness with the warning signs below needs 999.
