Waking up and feeling like the room is spinning isn't just a bad start to the morning. It’s a sign. For some, low blood pressure—or hypotension—is a constant, nagging shadow that makes standing up too fast feel like a carnival ride you didn’t ask to be on. Most of the world is obsessed with lowering their numbers, but if you're hitting $90/60$ mmHg or lower, your problem is the exact opposite. You need to know how do you raise your blood pressure without overshooting and causing long-term damage to your arteries. It’s a delicate balancing act.
Honestly, doctors often ignore low blood pressure unless you’re literally fainting in the waiting room. If you aren't symptomatic, they might even congratulate you on your "athletic" heart. But when the fatigue kicks in, or that brain fog makes you feel like you're walking through waist-deep molasses, "congratulations" is the last thing you want to hear.
The Salt Myth and Why You Might Need More
We’ve been told for decades that salt is the enemy. It’s the "silent killer," right? Well, not for you. If your pressure is bottoming out, sodium is actually your best friend. Sodium holds onto water in your bloodstream. More water means more blood volume. More volume means higher pressure. It’s basic physics in your veins.
Don't just start dumping table salt on everything, though. You want to be smart about it. Reach for high-quality sea salts or Himalayan salt which contain trace minerals. Think about olives, cottage cheese, or a quick cup of canned soup. It sounds counterintuitive to every health headline you've ever read, but for a hypotensive person, a salty snack is basically medicine.
Clinical guidelines from the Mayo Clinic suggest that increased salt intake can significantly help those with orthostatic hypotension—that specific "head rush" you get when standing. But here’s the kicker: you have to pair it with water. Salt without water just makes you thirsty and cranky; salt with water expands your plasma volume.

Water is the Engine Room
Drink more. No, seriously. More than that. Dehydration is the most common reason blood pressure dips into the danger zone. When you’re dehydrated, your total blood volume decreases. Imagine a garden hose with only a trickle of water running through it; there's no pressure.
You should be aiming for a steady intake throughout the day rather than chugging a liter all at once. If you’re active or live in a humid climate, your needs skyrocket. Pro tip: if you feel a "crash" coming on, drink two tall glasses of cold water immediately. The cold temperature can actually trigger a mild sympathetic nervous system response, giving you a slight, temporary boost while the hydration works on the volume side.
Compression and Physical Hacks
Sometimes the problem isn't that you don't have enough blood—it's just in the wrong place. Gravity is a jerk. When you stand up, blood naturally wants to pool in your legs and abdomen.
Compression stockings are the unglamorous hero of the hypotension world. They apply pressure to your lower legs, helping to squeeze that blood back up toward your heart and brain. You want the ones that offer at least 20-30 mmHg of pressure. They’re tight. They’re a pain to get on. But they work.
There are also "physical counter-maneuvers." If you feel yourself getting lightheaded, try these:
- Cross your legs while standing.
- Clench your fist and tense your arm muscles.
- Squeeze your thigh and glute muscles hard.
- The "squat and hold"—basically, if you feel like you’re going down, get lower to the ground to shorten the distance blood has to travel to your head.
These tricks aren't just old wives' tales. They are legitimate techniques taught to patients with Postural Orthostatic Tachycardia Syndrome (POTS) and other autonomic disorders. By tensing your muscles, you’re manually pumping blood through your veins.
Eating for Stability
Big meals are a trap. Have you ever noticed that you feel incredibly faint about thirty minutes after a huge Thanksgiving-style dinner? That’s because your body is diverting a massive amount of blood to your digestive tract to process all that food. This is called postprandial hypotension.

To fix this, stop eating three big meals. Switch to six small ones. Keep the carbs low-ish. High-carb meals, especially those full of refined sugars and white flours, cause a rapid spike and then a crash, which can pull your blood pressure down with it. Focus on protein, healthy fats, and complex fibers.
Caffeine: The Double-Edged Sword
A cup of coffee or caffeinated tea can give you a much-needed spike in pressure by stimulating the cardiovascular system and releasing adrenaline. It works. For many, a morning cup is the only way to get through the initial "low" of waking up.
However, caffeine is also a diuretic. It makes you pee. If you use caffeine to raise your blood pressure but forget to replace the fluids you're losing, you’ll end up lower than where you started a few hours later. Use it strategically, not as a crutch.
When to Talk to a Pro
Look, if you’re doing all the salt-and-water stuff and you’re still seeing stars every time you get off the couch, you need a doctor. Specifically, you might need to see a cardiologist or a neurologist who understands the autonomic nervous system.
There are medications for this. Fludrocortisone is a common one that helps your kidneys retain sodium. Midodrine is another; it works by narrowing your blood vessels so the pressure stays higher. These aren't things you just pick up at the drugstore, and they come with side effects, so they’re usually a last resort.
Check your current meds, too. Are you on antidepressants? Diuretics for something else? Alpha-blockers? A lot of drugs have "low blood pressure" tucked away in the fine print of the side effects list. Sometimes how do you raise your blood pressure is as simple as switching to a different medication for an unrelated issue.
The Anemia Connection
Sometimes the "pressure" isn't the problem, but what's in the blood is. If you're low on B12 or iron, your body can't produce enough red blood cells. This leads to anemia, which mimics many symptoms of low blood pressure. If you're feeling faint, ask for a full blood panel. It might not be your "plumbing" at all, but rather the quality of the "fluid" in the pipes.
Daily Habit Shifts
Don't jump out of bed. Seriously. When your alarm goes off, sit up slowly. Dangle your feet over the edge of the bed for a full minute. Flex your calves. Drink a glass of water you kept on the nightstand. Only then should you stand up.
If you’re a fan of long, steaming hot showers, I have bad news. Heat causes vasodilation—your blood vessels open up wide, which makes your pressure drop. Try lukewarm showers, or at least finish with a blast of cool water to constrict those vessels back up.
Actionable Steps to Take Right Now
If you're feeling the "dip" right now, or if you're tired of living in a blur, here is the immediate game plan:
- Drink 16 ounces of cold water. Do it over the next five minutes.
- Grab a salty snack. A handful of pickles or some salted nuts will do the trick.
- Check your position. If you’re sitting, cross your legs. If you’re standing, shift your weight and tense your calves.
- Track the data. Use a home blood pressure monitor at different times of the day—specifically when you feel "off"—so you can show your doctor real numbers, not just "I feel dizzy."
- Audit your hydration. Aim for 2-3 liters of fluid daily, and don't be afraid to use electrolyte powders that have a decent sodium hit (look for brands like LMNT or Liquid I.V. if you need a specific boost).
Raising your blood pressure is about consistency. It isn't a one-and-done fix. It's about changing how you move, how you eat, and how much you drink every single day. Stop treating your low numbers as a "blessing" and start treating them as a manageable condition that you have the tools to fix.
