Most dizziness episodes resolve on their own within minutes, and the steps you take during and after a spell can shorten it significantly. The right response depends on what type of dizziness you’re experiencing: a spinning sensation (vertigo), lightheadedness when standing, or a general feeling of unsteadiness. Each has different causes and different fixes.
What to Do During a Dizziness Spell
When dizziness hits, your first priority is not falling. Sit or lie down immediately, wherever you are. Avoid sudden movements, especially of your head. Keep still and rest until the sensation passes. Bright lights, screens, and reading can all intensify the feeling, so close your eyes or look at a fixed point on the floor if you need to keep them open.
If the room seems to spin when you stand up from sitting or lying down, the cause is often a temporary drop in blood pressure. Before you stand, try crossing your legs and tensing the muscles in your thighs, abdomen, and buttocks for several seconds. This squeezes blood back toward your brain. Clenching both fists hard or gripping your hands together and pulling your arms in opposite directions achieves a similar effect. These counter-pressure maneuvers, recommended by the American Heart Association, buy your cardiovascular system a few seconds to catch up. Once symptoms clear, stand slowly and pause before walking.
The Most Common Cause: Loose Crystals in Your Ear
If your dizziness feels like the room is spinning and it’s triggered by rolling over in bed, looking up, or tilting your head, you likely have benign paroxysmal positional vertigo, or BPPV. It’s the single most common cause of vertigo. Tiny calcium crystals called otoconia normally sit in one part of your inner ear, helping you sense gravity. When they break loose and drift into the semicircular canals (the fluid-filled tubes that detect rotation), any head movement can send false spinning signals to your brain. The episodes are brief, usually lasting seconds to a minute, but they can be intense.
Crystals dislodge for many reasons: aging, a bump to the head, inner ear infections, prolonged bedrest, migraines, diabetes, or osteoporosis. Sometimes there’s no obvious trigger at all.
The Epley Maneuver
The good news is that BPPV can often be fixed at home with a specific sequence of head positions that guide the loose crystals out of the canal. The Epley maneuver, described by Johns Hopkins Medicine, works like this for the right ear:
- Sit on a bed with a pillow behind you, positioned so it will be under your shoulders when you lie back.
- Turn your head 45 degrees to the right.
- Quickly lie back so your shoulders land on the pillow and your head reclines, touching the bed. Wait 30 seconds.
- Turn your head 90 degrees to the left (without lifting it) so you’re now looking 45 degrees to the left. Wait 30 seconds.
- Roll your body onto your left side, turning your head to look at the floor. Wait 30 seconds.
- Slowly sit up from that side position.
Repeat this three times before bed. If your left ear is the problem, reverse the directions. Many people feel relief after one or two sessions, though it can take a few days of repetition.
Brandt-Daroff Exercises
If the Epley maneuver doesn’t fully resolve your symptoms, Brandt-Daroff exercises are a gentler alternative that works through habituation, gradually training your brain to tolerate the abnormal signals. You sit on the edge of a bed, then quickly lie down on one side with your nose pointed slightly upward. Hold the position for 30 seconds, or until the dizziness stops if it lasts longer. Return to sitting, pause, then repeat on the other side. Do several repetitions at least twice a day.
Dizziness From Standing Up Too Fast
Lightheadedness when you go from lying or sitting to standing is called orthostatic hypotension. It happens because gravity pulls blood into your legs and your body doesn’t compensate fast enough. Dehydration, skipping meals, hot weather, and prolonged sitting all make it worse.
The practical fixes are straightforward. Drink enough water throughout the day, especially in warm weather or after exercise. Rise in stages: sit up for a few seconds before standing, then stand for a moment before walking. If you feel the dizziness starting as you stand, immediately cross your legs, tense your lower body muscles, and flex your neck by tucking your chin to your chest. Squatting down can also help if you feel you might faint. These actions physically push blood pressure back up toward your brain within seconds.
Medications That Cause Dizziness
A surprisingly long list of common medications can cause dizziness or unsteadiness as a side effect. Harvard Health identifies several major categories: blood pressure drugs (including diuretics, calcium channel blockers, and ACE inhibitors), antidepressants, anti-anxiety medications like benzodiazepines, antihistamines, sleep aids, opioid pain medications, nerve pain drugs, diabetes medications that lower blood sugar, heart medications like beta blockers, and stomach antispasmodic drugs.
If your dizziness started or worsened after beginning a new medication, or after a dose change, that connection is worth raising with your prescriber. Sometimes adjusting the timing of a dose (taking blood pressure medication at bedtime instead of morning, for example) reduces the problem without changing the drug itself. Don’t stop any prescribed medication on your own, but do keep track of when your dizziness occurs relative to when you take your pills. That pattern gives your doctor useful information.
Diet and Lifestyle Triggers
For people with recurring vertigo, particularly those with Meniere’s disease or vestibular migraines, certain dietary habits can make episodes more frequent. Sodium is the biggest culprit. Excess salt causes your body to retain fluid, which can increase pressure in the inner ear. The recommended target is around 1,500 mg of sodium per day, with 2,300 mg as an upper limit. For context, a single fast-food meal can easily exceed 1,500 mg.
Caffeine and alcohol may also worsen symptoms by constricting blood vessels and reducing blood flow to the inner ear. The research on this is limited, but many people with vestibular conditions report improvement after cutting back. High sugar intake is another potential trigger. Current dietary guidelines recommend keeping added sugars below about 12 teaspoons per day on a 2,000-calorie diet.
Dehydration is a trigger that cuts across nearly every type of dizziness. It reduces blood volume, which lowers blood pressure and makes both orthostatic lightheadedness and vertigo episodes more likely. Steady fluid intake throughout the day is one of the simplest and most effective preventive steps.
When Dizziness Is a Medical Emergency
Most dizziness is harmless, but in rare cases it signals something serious. Vertigo is actually the most common warning symptom before a stroke in the arteries supplying the back of the brain. What makes this dangerous is that fewer than 20 percent of stroke patients whose main symptom is dizziness or vertigo have obvious neurological signs like facial drooping or arm weakness. Young adults between 18 and 44 are seven times more likely to be misdiagnosed than older patients, partly because doctors don’t expect strokes in younger people.
Seek emergency care if your dizziness comes with any of the following: a sudden, severe headache or neck pain that’s unlike anything you’ve experienced before; difficulty speaking or slurred speech; double vision or sudden vision loss; numbness or weakness on one side of your body; difficulty walking or a sudden loss of coordination. A new onset of sustained vertigo that doesn’t stop after several hours, especially with vomiting and an inability to walk, also warrants urgent evaluation. Cardiac arrhythmias can produce true spinning vertigo too, so dizziness paired with a pounding, racing, or irregular heartbeat deserves prompt attention.
How Doctors Diagnose the Cause
If dizziness keeps recurring, a doctor can usually identify the type through targeted physical tests done in the office. The Dix-Hallpike maneuver is the standard screening test for BPPV. Your provider moves you from sitting to lying down with your head turned 45 degrees to one side and watches your eyes for involuntary jerking movements called nystagmus. If those movements appear, the diagnosis is confirmed. A negative result prompts a second test called the supine head roll, where you lie flat and your head is turned side to side, which catches less common forms of BPPV affecting a different canal.
For dizziness that doesn’t fit the BPPV pattern, doctors may order hearing tests, blood pressure monitoring in different positions, blood work to check for anemia or blood sugar problems, or imaging if a neurological cause is suspected. Keeping a log of when your episodes happen, how long they last, what position you were in, and what you ate or drank beforehand makes these appointments far more productive.
