If you’re feeling dizzy and nauseous right now, the most important thing is to lie down in a safe position until the dizziness passes. When you’re ready to get up, move slowly and carefully. Beyond that immediate step, what you do next depends on what’s causing the symptoms, how often they happen, and whether certain warning signs are present.
What to Do Right Now
Lie down on a flat surface, ideally on your side in case the nausea leads to vomiting. Keep your eyes focused on a fixed point in the room rather than closing them, which can sometimes make the spinning sensation worse. If lying down isn’t possible, sit with your head between your knees.
A few environmental adjustments help: turn off bright overhead lights, reduce screen time, and avoid sudden head movements. Sip small amounts of cool water. Don’t try to stand or walk until the dizziness has fully cleared, because the fall risk is real, especially on hard floors or near stairs.
Why Dizziness and Nausea Happen Together
These two symptoms share a common wiring system. Your inner ear controls balance, and when it sends conflicting signals to the brain, the result is dizziness. That same mismatch triggers the nausea center in your brainstem, which is why the two symptoms so often arrive as a pair. The most common triggers include inner ear conditions (like loose crystals in the ear canal, known as BPPV, or inner ear infections), motion sickness, medication side effects, dehydration, and migraines that affect the vestibular system.
Less commonly, low blood pressure, blood sugar drops, carbon monoxide exposure, and anxiety disorders can produce the same combination. Carbon monoxide poisoning is worth knowing about specifically because its symptoms mimic the flu: headache, dizziness, weakness, nausea, vomiting, and confusion. If multiple people in the same building feel sick simultaneously, get outside immediately.
Acupressure for Nausea Relief
A pressure point on the inner wrist called P6 can reduce mild nausea without any medication. To find it, place three fingers from your opposite hand flat across your wrist, just below the crease where your hand meets your arm. Then press your thumb into the groove between the two large tendons that run down the center of your wrist. Apply firm, steady pressure for one to two minutes. It shouldn’t hurt. This technique works well enough that wristbands designed to press on this point are sold specifically for motion sickness and morning sickness.
Ginger for Nausea
Ginger is one of the most studied natural remedies for nausea. It works by speeding up the movement of food through the digestive tract and by acting on receptors in the gut and brain that trigger the vomiting reflex. Clinical trials have used doses ranging from 250 mg to 1 g taken in divided doses throughout the day, and the higher 2 g doses didn’t show additional benefit over 1 g. In practical terms, that means a cup or two of strong ginger tea, a few ginger chews, or a ginger supplement capsule can provide real relief. Fresh ginger sliced into hot water is an easy option if you have it on hand.
The Epley Maneuver for Spinning Vertigo
If your dizziness feels like the room is spinning (true vertigo), especially when you roll over in bed or tilt your head back, the cause is often tiny calcium crystals that have drifted into the wrong part of your inner ear canal. This is BPPV, and it responds remarkably well to a simple head-repositioning technique called the Epley maneuver.
To do it at home, sit on your bed. 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. Wait 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, keeping your head in position. Wait 30 seconds again, then slowly sit up. If your affected ear is on the left side, reverse the directions. The maneuver works by guiding those loose crystals back to where they belong, and many people feel relief after just one or two attempts.
Over-the-Counter Medication
Meclizine is the most commonly used over-the-counter option for dizziness and nausea. For motion sickness, the standard adult dose is 25 to 50 mg taken one hour before travel, with another dose allowed every 24 hours. For vertigo caused by inner ear problems, doses range from 25 to 100 mg per day split into smaller amounts throughout the day. The main side effect is drowsiness, so avoid driving or operating anything that requires sharp focus. Dry mouth, headache, and blurred vision can also occur.
Dimenhydrinate (the active ingredient in Dramamine) is another option with a similar mechanism. Both work by blocking histamine receptors in the brain that contribute to the nausea-dizziness loop. These medications are meant for short-term use. If you find yourself reaching for them regularly, that’s a sign the underlying cause needs attention.
Hydration and Electrolytes
Dehydration is one of the most overlooked causes of dizziness and nausea combined. When fluid levels drop, blood volume decreases, blood pressure falls, and your brain gets less oxygen, all of which produce that lightheaded, queasy feeling. This is especially common after exercise, illness with vomiting or diarrhea, excessive heat exposure, or simply not drinking enough water throughout the day.
Plain water helps, but if you’ve been vomiting or sweating heavily, you also need to replace electrolytes like sodium and potassium. Oral rehydration solutions (sold as packets at any pharmacy) contain the right balance of sugar and salt to help your body absorb fluid more efficiently. Sports drinks work in a pinch, though they contain more sugar than necessary. Sip slowly rather than gulping, since a large volume of liquid hitting an already upset stomach can make nausea worse.
Vestibular Exercises for Recurring Dizziness
If dizziness is a recurring problem, a set of balance-retraining exercises can help your brain recalibrate its relationship with your inner ear. These are sometimes called vestibular habituation exercises, and the principle is straightforward: by repeatedly exposing your balance system to controlled movements that provoke mild dizziness, you teach your brain to compensate and stop overreacting.
A basic routine includes three categories of movement:
- Eye and head movements: While sitting, move your eyes up and down 20 times while focusing on your finger. Then side to side 20 times. Then move your finger from arm’s length to the tip of your nose and back, keeping your eyes locked on it.
- Sitting to standing: Rise from a chair and sit back down 20 times with your eyes open. Repeat this three times per session.
- Walking in a line: In a hallway or next to a wall, walk heel-to-toe in a straight line for five minutes, with the heel of one foot touching the toe of the other.
An intermediate challenge involves holding a visual target (like a playing card) and slowly moving it up and down or side to side while moving your head in the opposite direction, for 30 seconds at a time. Do these exercises at least three times a day for a minimum of 6 to 12 weeks. The key detail most people miss: stopping too early often causes symptoms to return. Continue until you’ve had two consecutive weeks with no dizziness at all, then stop. If symptoms come back later, restart the routine.
Have someone nearby the first few times you try these, especially the standing exercises. They can provoke significant dizziness initially, and that’s actually the point. It gets easier.
Dietary Triggers Worth Knowing
For people whose dizziness and nausea are linked to vestibular migraines or inner ear fluid problems, certain dietary patterns make episodes more likely. Caffeine is a common trigger, and guidelines from UC Davis Health recommend capping intake at no more than two servings per day. Just as important: keep the amount and timing consistent from day to day. It’s the fluctuation in caffeine levels, not just the total amount, that tends to trigger episodes.
High sodium intake can worsen inner ear fluid imbalances, so keeping salt to small amounts and avoiding heavily pickled, preserved, or processed foods helps. MSG (monosodium glutamate), aged cheeses, and alcohol are other well-documented triggers. If you notice a pattern where symptoms follow certain meals, keeping a simple food diary for two weeks can reveal connections that aren’t obvious in the moment.
Warning Signs That Need Emergency Care
Most episodes of dizziness and nausea resolve on their own or with the measures above. But certain combinations signal something more serious. Seek emergency care if your dizziness comes with sudden severe headache, difficulty speaking or understanding speech, vision loss, weakness or numbness on one side of the body, chest pain, or a heartbeat that feels rapid or irregular. These patterns can indicate a stroke or cardiac event. Dizziness after a head injury also warrants immediate evaluation, even if you feel otherwise fine.
