When nausea hits and you feel like you’re about to throw up, there are several things you can do right now to calm the reflex. Some techniques work in seconds, others take a few minutes, but most rely on the same basic principle: interrupting the signals your brain is sending to your stomach. Here’s what actually works, starting with the fastest options.
Why Your Body Wants to Vomit
Vomiting isn’t random. Your brain has a dedicated detection zone on the floor of the fourth ventricle (a fluid-filled space deep in the brainstem) that constantly monitors your blood for anything that shouldn’t be there. When it spots a problem, whether that’s a toxin, a medication side effect, or a hormone surge, it fires a signal to the vomiting center. That center then coordinates your diaphragm, abdominal muscles, and throat to force everything up.
But your blood isn’t the only trigger. Signals also come from your gut itself, from your inner ear (which is why motion sickness exists), and from higher brain areas involved in anxiety, smells, and even memory. That’s why you can feel sick just from seeing something disgusting or thinking about a bad meal. Each of these pathways can be interrupted differently, which is why combining a few techniques tends to work better than relying on just one.
Cold on Your Face Works Fast
One of the quickest ways to fight nausea is to press something cold against your forehead, eyes, or cheeks. This triggers what’s called the diving response, a reflex built into all air-breathing animals. Cold stimulates nerves in your face that connect directly to your vagus nerve, the main nerve controlling your gut, heart rate, and digestion. When the vagus nerve activates this way, it shifts your nervous system into a calmer state: your heart rate drops, and the chaotic gut signals driving the nausea quiet down.
A cold, wet washcloth across your forehead and around your eyes is the simplest version. A bag of ice or a cold pack wrapped in a thin towel works too. Hold it there for at least 30 seconds. You can also splash cold water on your face repeatedly.
Controlled Breathing and the P6 Pressure Point
Slow, deliberate breathing helps because it directly activates the same calming branch of the nervous system that the cold trick targets. Breathe in through your nose for four counts, hold for two, and breathe out through your mouth for six. The longer exhale is key. Repeat this for a minute or two.
While you’re breathing, try pressing firmly on the P6 acupressure point. It’s on the inside of your forearm, about three finger widths above the crease of your wrist, in the groove between the two tendons you can feel when you flex your hand. Press firmly with your thumb for two to three minutes. Clinical trials on nausea patients have found that sustained pressure at this point significantly reduces both the severity of nausea and the frequency of vomiting compared to placebo. This is also the spot targeted by anti-nausea wristbands sold in pharmacies.
What to Sip and What to Avoid
When you’re actively nauseous, taking small sips of a cold or room-temperature liquid is better than drinking a full glass. Ice chips are ideal because they deliver tiny amounts of fluid without stretching your stomach. Clear broth, diluted apple juice, or a flat ginger ale can help, but avoid anything carbonated, caffeinated, or acidic (like orange juice) since these can irritate your stomach lining and make things worse.
If you’ve already been vomiting and are trying to recover, rehydration matters more than most people realize. The most effective approach is an oral rehydration solution, which balances water with small amounts of salt, potassium, and sugar in specific ratios. Store-bought versions like Pedialyte follow the WHO formula of roughly 70 milliequivalents of sodium and 20 of potassium per liter. You can approximate this at home with a liter of clean water, six level teaspoons of sugar, and half a teaspoon of salt. Sip slowly, a tablespoon at a time, every few minutes.
Ginger and Vitamin B6
Ginger is one of the few natural remedies with solid clinical backing for nausea. A meta-analysis of 10 randomized controlled trials found that doses between 0.5 and 2 grams per day significantly reduced vomiting, particularly within the first 24 hours. That’s roughly a half-inch piece of fresh ginger grated into hot water, or one to two ginger capsules from a supplement aisle. Ginger chews and ginger tea also work, as long as they contain real ginger rather than just flavoring. The compounds in ginger appear to act on the same serotonin receptors in the gut and brainstem that prescription anti-nausea drugs target.
Vitamin B6 is specifically recommended for pregnancy-related nausea. The American College of Obstetrics and Gynecology recommends 10 to 25 milligrams taken three or four times a day. Even outside of pregnancy, some people find B6 helpful for general nausea, though the strongest evidence is for morning sickness.
Over-the-Counter Medications
If home remedies aren’t cutting it, antihistamine-based anti-nausea medications are widely available without a prescription. These work by blocking histamine receptors in the brainstem’s vomiting center and vestibular system. Many also block a second type of receptor involved in nausea signaling, which is why they’re more effective than you might expect from a simple “allergy” drug. They need to cross into the brain to work, which is also why they tend to cause drowsiness.
Bismuth subsalicylate (the active ingredient in Pepto-Bismol) takes a different approach, coating and calming the stomach lining directly. It’s better for nausea caused by food or stomach bugs than for motion sickness. For motion-related nausea, the antihistamine options are more effective because they target the inner-ear signals driving the problem.
Positioning and Environment
What you do with your body matters. Sitting upright or reclining with your head elevated reduces pressure on your stomach and keeps acid where it belongs. Lying flat, especially on your stomach, compresses your abdomen and can push you over the edge. If you need to lie down, your left side is generally best because of how your stomach is oriented.
Fresh air helps. Open a window or step outside. Strong smells, warm stuffy rooms, and visual motion (like scrolling on a phone) all feed signals into the brain’s nausea circuits. Minimizing sensory input gives your nervous system less to react to. If cooking smells or perfume triggered the nausea, removing yourself from the source can be enough on its own.
What to Eat After Nausea Passes
The old advice was to stick to the BRAT diet: bananas, rice, applesauce, and toast. While these foods are easy on the stomach, current medical consensus no longer recommends the BRAT diet specifically because it lacks sufficient nutrition and prolonged use can leave you short on protein, fat, and key vitamins. Instead, start with small portions of whatever bland foods appeal to you. Crackers, plain potatoes, broth-based soups, and eggs are all fine choices. Eat slowly, and stop if nausea returns. Most people can return to a normal diet within 24 to 48 hours.
Avoid greasy, spicy, or heavily seasoned food for the first day. Large meals are harder to keep down than several small ones eaten a couple of hours apart.
Warning Signs That Need Medical Attention
Most nausea and vomiting resolves on its own, but certain combinations of symptoms point to something more serious. Get to an emergency room if your vomit contains blood, looks like coffee grounds, or is bright green. These can indicate bleeding or a bowel obstruction. The same applies if vomiting comes with severe abdominal pain or cramping, chest pain, confusion, blurred vision, or a high fever with a stiff neck.
Dehydration is the other major concern, especially in children and older adults. Signs include dark urine, dry mouth, dizziness when standing, and urinating much less than usual. If you can’t keep any fluids down for more than 12 hours, or if a child can’t keep fluids down for 8 hours, that warrants urgent care. Persistent vomiting lasting more than 24 to 48 hours with no clear cause (like a known stomach bug) also deserves evaluation.
