Dizziness and nausea often improve with a combination of simple home strategies: staying hydrated, trying ginger, using pressure point techniques, and in some cases taking an over-the-counter antihistamine. The right approach depends on what’s causing your symptoms, but several remedies work across multiple causes and can bring relief quickly.
Start With Hydration
Dehydration is one of the most common and overlooked causes of dizziness and nausea. When your body loses more fluid than it takes in, your blood volume drops, your blood pressure falls, and your brain doesn’t get the steady supply it needs. The fix is straightforward: replace lost fluids and electrolytes. Most adults with mild to moderate dehydration from illness, heat, or not drinking enough can recover by simply increasing their fluid intake.
Water alone works for mild cases. If you’ve been vomiting, sweating heavily, or dealing with diarrhea, a drink with electrolytes (sodium and potassium, specifically) helps your body absorb fluid faster. Sports drinks diluted with equal parts water are a reasonable option. Sip slowly rather than gulping, especially if nausea is present, since flooding your stomach can make things worse.
Ginger for Nausea Relief
Ginger has genuine anti-nausea properties. It appears to work by blocking certain serotonin receptors in both the gut and the brain, which are key players in the nausea response. Most clinical research has used between 250 mg and 1 g of powdered ginger root in capsule form, taken one to four times daily. For pregnancy-related nausea, the most studied dose is 250 mg four times a day.
You don’t need capsules to get the benefit. Ginger tea, ginger chews, and even flat ginger ale (with real ginger, not just flavoring) can help settle your stomach. The key is getting enough of the active compounds, so concentrated forms like capsules or strong tea tend to be more reliable than a ginger snap cookie.
The P6 Pressure Point
There’s a spot on your inner forearm, about three finger-widths from the crease of your wrist and centered between the two tendons, known as the P6 acupressure point. Firm pressure or gentle circular massage at this spot can reduce nausea related to motion sickness and pregnancy. It’s the same principle behind anti-nausea wristbands. This won’t cure serious vertigo, but it costs nothing, has no side effects, and can take the edge off while you figure out the underlying cause.
Over-the-Counter Antihistamines
Meclizine is the most widely used OTC medication for dizziness and nausea. It works by blocking signals to the brain that trigger those symptoms. For motion sickness, the typical dose is 25 to 50 mg taken an hour before travel, with no more than one additional dose in 24 hours. For vertigo, doses range from 25 to 100 mg per day split across multiple doses.
Dimenhydrinate (the active ingredient in Dramamine) works through a similar mechanism. Both medications cause drowsiness, which can actually be helpful if your dizziness is keeping you from resting. They’re most effective for motion-related dizziness and inner ear problems, and less useful for dizziness caused by dehydration, low blood sugar, or blood pressure changes.
When the Cause Is Your Inner Ear
The most common inner ear cause of dizziness is benign paroxysmal positional vertigo, or BPPV. It happens when tiny calcium crystals inside your inner ear drift out of position and end up in one of the semicircular canals, the fluid-filled tubes your brain uses to sense head movement. Once displaced, these crystals make the canal hypersensitive to certain head positions, sending false motion signals to your brain. The result is sudden, intense spinning that hits when you tilt your head, roll over in bed, or look up.
The Epley maneuver is a specific sequence of head and body positions designed to guide those crystals back where they belong. You can do it at home on a bed with a pillow positioned under your shoulders. It’s safe, free, and often resolves the problem in one or two sessions. Your doctor or a physical therapist can walk you through the exact steps for your affected ear, since the direction of the movements depends on which ear is involved.
Vestibular Exercises for Ongoing Dizziness
If your dizziness lingers or keeps coming back, vestibular rehabilitation exercises can retrain your brain’s balance system. These are simple movements you do at home, progressing through levels as your tolerance improves.
One foundational exercise is gaze stabilization. Sit in a chair about five feet from a wall and fix your eyes on a small target at eye level, like a word or letter. While keeping your eyes locked on the target, slowly shake your head side to side for one minute, as if saying “no.” Then repeat with an up-and-down nodding motion. The goal is to keep the target in focus while your head moves. As you improve, you increase the speed, try it standing, and eventually do it while walking toward the target and back.
Another exercise involves clasping your hands in front of you with thumbs up, then rotating your head, eyes, and upper body together to look left, then right, keeping your gaze on your thumbs. Start seated, progress to standing, and eventually try it on an uneven surface like a thick pillow. These exercises feel uncomfortable at first because they deliberately challenge your balance system, but that mild discomfort is what drives adaptation.
Dietary Triggers Worth Knowing
For people whose dizziness is linked to vestibular migraines (a type of migraine that causes vertigo instead of, or in addition to, headache), certain foods and drinks can set off episodes. The biggest culprits include alcohol (especially red wine, beer, and sherry), aged cheeses like cheddar, brie, and parmesan, chocolate, processed meats like salami and hot dogs, and anything containing MSG or “natural flavoring” that hides glutamate.
Caffeine is a particular problem when consumed inconsistently. Guidelines from UC Davis Health recommend no more than two servings per day, and keeping the amount and timing the same every day. Sudden increases or decreases in caffeine can trigger episodes on their own. Citrus fruits and juices should be limited to about half a cup per day, and artificial sweeteners like aspartame are on the avoid list as well.
Not everyone with dizziness has vestibular migraines, but if your episodes seem to follow meals or certain foods, keeping a food diary for a few weeks can reveal patterns you’d otherwise miss.
Quick Relief in the Moment
When a wave of dizziness and nausea hits, a few immediate steps can help. Sit or lie down right away to reduce your fall risk and give your brain a stable reference point. Fix your gaze on a single stationary object. Breathe slowly and deeply through your nose, since rapid breathing can make dizziness worse by changing your blood carbon dioxide levels. Avoid sudden head movements, and if you’re lying down, keep your head slightly elevated rather than flat.
Cool air across your face, whether from a fan, an open window, or a cold cloth on your forehead, can ease nausea surprisingly well. Avoid strong smells, heavy food, and screens until the episode passes. Small sips of cold water or ginger tea are easier to keep down than large drinks.
Red Flags That Need Emergency Care
Most dizziness and nausea are uncomfortable but not dangerous. However, certain combinations of symptoms point to something more serious. Seek emergency care if your dizziness comes with a sudden severe headache, chest pain, difficulty breathing, numbness or weakness on one side of your body, confusion, trouble speaking, double or blurred vision, a rapid or irregular heartbeat, or if it follows a head injury. These can signal a stroke, heart problem, or brain injury where minutes matter.
