If you’re feeling dizzy right now, sit or lie down immediately. This is the single most important step to prevent a fall or fainting episode. Once you’re in a safe position, you can figure out what’s causing it and what to do next.
What to Do Right Now
Sit or lie down as soon as the dizziness starts. If the room feels like it’s spinning intensely, lie still with your eyes closed in a darkened room. Avoid any fast or sudden head movements, which can make everything worse.
If you’ve been in the heat, exercising, or haven’t had enough water, move to a cool place and drink water or a sports drink. Dehydration and overheating are among the most common and easily fixable causes of dizziness. If you haven’t eaten in several hours, have a snack. Blood sugar dropping below about 70 mg/dL can trigger lightheadedness, shakiness, and confusion, even in people without diabetes.
If you stood up quickly and the dizziness hit, that’s likely a blood pressure drop. Your body sometimes needs a moment to adjust when you change positions. Next time, rise slowly: sit on the edge of the bed for a few seconds before standing, and hold onto something stable.
When Dizziness Is an Emergency
Most dizziness is not dangerous. But certain combinations of symptoms point to a stroke or other serious problem. Call emergency services if your dizziness comes with any of these:
- Numbness or weakness in your face, arm, or leg, especially on one side
- Trouble walking or sudden stumbling
- Confusion or slurred speech
- Sudden, severe headache unlike anything you’ve experienced
These symptoms together can indicate that blood flow to the brain has been disrupted. Don’t wait to see if they improve on their own.
Spinning vs. Lightheadedness
Not all dizziness feels the same, and the type you’re experiencing points toward different causes. Lightheadedness is a woozy, faint feeling where your balance just seems off and you feel like you might fall if you don’t sit down. It’s commonly triggered by dehydration, low blood sugar, standing up too fast, or anxiety.
Vertigo is different. It’s the sensation that you or your surroundings are actively spinning or moving when nothing is actually moving. Vertigo almost always involves the inner ear or the brain’s balance-processing systems. If you’re experiencing true spinning, the cause and treatment are more specific.
Common Causes Worth Knowing
Inner Ear Crystal Displacement (BPPV)
The most common cause of vertigo is a condition called benign paroxysmal positional vertigo, or BPPV. Inside your inner ear, tiny calcium carbonate crystals help your brain sense head position and balance. Sometimes these crystals break loose from their normal location and drift into the semicircular canals, the fluid-filled tubes that detect rotation. Once trapped there, the crystals roll around whenever you move your head, pushing on delicate hair-like sensors and sending false spinning signals to your brain.
BPPV typically causes brief but intense vertigo triggered by specific movements: rolling over in bed, tilting your head back, or looking up. Each episode usually lasts less than a minute but can be frightening. The good news is that BPPV responds well to a simple repositioning technique you can do at home (more on that below).
Inner Ear Infections
Inflammation of the inner ear structures can cause prolonged vertigo lasting days or even weeks. When the infection affects the balance and hearing organs together, it’s called labyrinthitis, and it typically causes both vertigo and hearing loss. When only the balance nerve is inflamed, it’s vestibular neuritis, which causes vertigo without significant hearing changes. Both conditions come on suddenly and improve gradually, often with the help of balance-focused physical therapy.
Blood Pressure Drops
A drop of 20 mmHg or more in your upper blood pressure number when you stand up is considered abnormal and is called orthostatic hypotension. It’s especially common in older adults, people who are dehydrated, and those taking blood pressure medications. The dizziness usually passes within seconds to a couple of minutes as your cardiovascular system catches up.
Medications
Dizziness is one of the most frequently reported side effects across a wide range of medications. Drug classes known to affect balance include antidepressants, anti-anxiety medications (particularly benzodiazepines), antihistamines, blood pressure drugs, diabetes medications, opioid pain relievers, sleep aids, and heart medications like beta blockers. These drugs can cause blurred vision, drowsiness, impaired judgment, and weakened muscles on top of the dizziness itself. If your dizziness started or worsened after beginning a new medication, that connection is worth discussing with whoever prescribed it.
The Epley Maneuver for Vertigo
If your dizziness feels like spinning triggered by head position changes, the Epley maneuver can often resolve it in one or two sessions. This technique works by guiding the loose crystals out of your semicircular canals and back to where they belong. Here’s the basic sequence for the right ear (reverse left and right if your left ear is affected):
Sit on a bed with your legs straight out. Turn your head 45 degrees to the right. Quickly lie back so your shoulders land on a pillow and your head reclines, touching the bed while still turned. Hold that position for 30 seconds. Then turn your head 90 degrees to the left without lifting it, so you’re now looking 45 degrees to the left. Wait another 30 seconds. Roll your body onto your left side while keeping your head in position, then slowly sit up.
You may feel a brief surge of vertigo during the maneuver as the crystals move. That’s actually a sign it’s working. Many people feel significant relief after just one or two repetitions. If you’re unsure which ear is affected or the maneuver doesn’t help after a few tries, a physical therapist or doctor can guide you through it.
Reducing Dizziness Over Time
If dizziness is a recurring problem, a few changes to your daily routine can help. Stay consistently hydrated throughout the day rather than catching up all at once. Eat regular meals to keep blood sugar stable. When getting out of bed in the morning, sit upright for 10 to 15 seconds before standing.
Fall-proofing your home matters more than most people realize, especially if dizziness strikes unpredictably. Remove area rugs and loose cords you could trip over. Put nonslip mats in your shower and bathtub. Make sure hallways and stairways are well lit. A cane can help with balance if you need it.
If dizziness keeps coming back, doesn’t improve with hydration and rest, or interferes with your daily life, it’s worth getting evaluated. Doctors can perform specific eye-movement and balance tests to distinguish between inner ear problems and more serious causes. For most people, the underlying issue turns out to be highly treatable once it’s properly identified.
