Ever felt that sudden, dizzying wave where the room starts spinning because you stood up too fast? Your head goes light. Your vision blurs at the edges. It’s annoying. For some, it’s actually dangerous. While the world is usually obsessed with lowering blood pressure, plenty of people are walking around with numbers so low they feel like zombies. If you’re searching for how to increase your blood pressure quickly, you’re likely dealing with hypotension—that sluggish, faint feeling that makes getting through a workday feel like wading through molasses.
Most people think "low" is always "good." Not always.
When your systolic pressure dips below 90 mm Hg or your diastolic falls under 60 mm Hg, you've officially entered the hypotension zone. It’s not just a number on a cuff. It’s about how your brain gets oxygen. If the pressure is too low, the pump just doesn't prime. You need a fix, and you usually need it before you pass out in the grocery aisle.
Salt is Your New Best Friend (Seriously)
Forget everything you’ve heard about low-sodium diets for a second. If you need to know how to increase your blood pressure quickly, salt is the most immediate lever you can pull. Sodium holds onto water. More water in your bloodstream means more volume. More volume equals higher pressure. It’s basic physics.
Grab a glass of water and stir in about half a teaspoon of sea salt. Or drink a cup of bouillon. It’s salty. It’s savory. It works almost instantly. Research from the Mayo Clinic suggests that increasing salt intake can be a primary defense against orthostatic hypotension—that specific "head rush" you get from standing.
Don't overdo it long-term without talking to a doctor, obviously. But in the moment? A bag of salty pretzels or a shot of soy sauce can literally save your afternoon. It’s a tool. Use it.

The Water Chug Method
Dehydration is the silent killer of healthy blood pressure. When you’re dehydrated, your blood volume drops. Think of it like a garden hose; if there’s barely any water flowing through, the pressure against the walls of the hose is nonexistent.
Drink a full 16 to 20 ounces of cold water fast. Not a sip. A chug.
There’s a fascinating physiological response called the "water pressor effect." Studies published in journals like Circulation have shown that drinking a large amount of water rapidly can significantly raise systolic blood pressure in people with autonomic failure or chronic low pressure. The effect starts within minutes and can last for over an hour. It’s a clean, calorie-free way to get your numbers up when you feel a fainting spell coming on.
Cross Your Legs and Squeeze
Sometimes you can’t get to a kitchen. You’re in a meeting or standing in line. This is where physical maneuvers come in. You have to manually force the blood back up to your heart and brain.
Cross your legs while standing. Squeeze your thigh muscles. Tense your calves. This "muscle pumping" action compresses the veins in your lower extremities. Since veins have one-way valves, this pressure pushes blood upward.
- Try the "Counter-Pressure" maneuver: Cross one leg over the other and squeeze.
- Clench your fists hard for 30 seconds.
- Tense your glutes like you’re trying to hold a coin between them.
It sounds silly. It looks a bit weird. But it works. By shifting the blood out of your legs and into your core, you provide an immediate, temporary spike in systemic pressure.
The Caffeine Kick (With a Warning)
Caffeine is a vasoconstrictor. It tells your blood vessels to tighten up. When the pipes get smaller, the pressure goes up.
A double espresso or a strong cup of black tea can provide that necessary jolt. However, there’s a catch. Caffeine is also a diuretic. If you drink three cups of coffee and forget to drink water, you’ll eventually pee out more fluid than you took in, which will actually lower your blood pressure an hour later.
Always pair your caffeine with a glass of water. It’s a synergistic move. The caffeine tightens the vessels while the water fills them. This is a classic "quick fix" for people who struggle with postprandial hypotension—the sudden drop in blood pressure that happens right after eating a big meal.
Compression Garments: The Long Game
If this is a daily struggle for you, "quickly" might mean "how do I stop this from happening every morning?"
Compression stockings are the gold standard here. They aren't just for your grandmother. Modern athletic compression gear does the same thing. By applying constant pressure to the lower legs, these garments prevent blood from "pooling" in your feet.
When blood pools, it stays away from your brain. That’s bad. Grade 1 or Grade 2 medical compression stockings (20-30 mmHg) are usually enough to keep the average person from feeling faint. Put them on before you even get out of bed in the morning.
Why Your "Healthy" Meals Might Be Hurting You
If you’re eating huge, carb-heavy meals, your body is diverting a massive amount of blood to your digestive tract to process all that glucose. This is why you feel like taking a nap after a big bowl of pasta. For people with low blood pressure, this "food coma" is actually a clinical drop in pressure.
Switch to smaller, more frequent meals. Focus on protein and complex fats. This keeps your blood distribution more even throughout the day. It prevents the "theft" of blood from your brain to your stomach.
Watch Out for These Triggers
- Hot Showers: Heat dilates your blood vessels (vasodilation). This causes your pressure to tank. If you’re prone to low BP, keep the water lukewarm and finish with a cold blast to constrict those vessels.
- Alcohol: It’s a vasodilator and a diuretic. A double whammy for low blood pressure. If you’re already feeling dizzy, skip the wine.
- Rapid Position Changes: Never jump out of bed. Sit on the edge for 30 seconds. Flex your ankles. Let your body calibrate.
When to Actually Worry
Low blood pressure is often a sign of fitness in athletes, but it can also mask underlying issues. If you are feeling chronically cold, tired, and dizzy, you might be dealing with something more than just "low numbers."
- Anemia: Not enough red blood cells to carry the oxygen.
- Vitamin B12 Deficiency: Can cause neurological issues and low BP.
- Endocrine Issues: Problems with your thyroid or adrenal glands (Addison's disease) often manifest as low blood pressure.
- Heart Valve Issues: If the pump is broken, the pressure will be low.
If you’re experiencing chest pain, shortness of breath, or a pulse that feels like a hummingbird’s wings, stop reading articles and go to the ER. Otherwise, the salt-and-water combo is your best bet for a fast recovery.
Real-World Action Steps
If you need to know how to increase your blood pressure quickly right this second, do these three things in order:
Drink 16 ounces of cold water as fast as comfortably possible. This triggers the pressor response and adds volume.
Eat something very salty. A handful of olives, a pickle, or a half-teaspoon of salt in water. This holds the water in your system.
Engage your muscles. Do 10 calf raises or squeeze your thighs together while sitting or standing. This physically moves the blood.
Keep a log of when these drops happen. If it's always after a meal, it's your diet. If it's always when you stand up, it's orthostatic. If it's all the time, see a doctor about your electrolytes or heart health. Small changes in how you move and what you consume make a massive difference in how your brain feels throughout the day.
