If your blood pressure consistently reads below 90/60 mmHg and you’re dealing with dizziness, fatigue, or lightheadedness, several natural strategies can bring it up. Most involve simple changes to how you eat, drink, and move throughout the day. Here’s what actually works and why.
Increase Your Salt Intake
Salt is the most direct dietary tool for raising blood pressure. Sodium causes your body to retain more water, which increases blood volume and puts more pressure on your vessel walls. While most health advice warns people to cut back on sodium, the opposite applies when your blood pressure runs low.
For people with low blood pressure, a daily intake of at least 6 grams of salt (about one teaspoon) is a common target. That’s roughly double what’s recommended for the general population. You can get there by salting your meals more liberally, snacking on salted nuts or olives, or adding broth-based soups to your routine. If you have any kidney or heart conditions, talk to your doctor before increasing sodium, since those conditions change how your body handles salt.
Drink More Water, and Drink It Quickly
Staying hydrated helps maintain blood volume, but the way you drink water matters more than you might expect. Research published in Circulation found that drinking about two cups (480 mL) of water raised blood pressure by 11 mmHg in older adults within minutes. The effect was even more dramatic in people with autonomic nervous system disorders, where the same amount raised systolic pressure by over 40 mmHg.
Interestingly, the blood pressure boost from drinking water isn’t just about adding fluid volume. The act of swallowing water triggers your sympathetic nervous system, the same system responsible for your fight-or-flight response, which tightens blood vessels and pushes pressure up. Drinking a larger volume produced a stronger effect than drinking a smaller one, so having a full glass rather than sipping throughout the hour makes a difference.
Aim for at least eight glasses of water a day as a baseline, and try drinking a full glass before standing up or before situations where you tend to feel dizzy.
Eat Smaller, More Frequent Meals
Large meals can cause a noticeable drop in blood pressure, a condition called postprandial hypotension. After you eat, your body redirects blood toward your digestive system. Normally, your heart rate increases and blood vessels elsewhere tighten to compensate. But if those responses don’t kick in strongly enough, your blood pressure falls, sometimes enough to cause dizziness or faintness 30 to 60 minutes after eating.
The fix is straightforward: eat six smaller meals instead of three large ones. Spreading your food intake across the day prevents your digestive system from demanding a large blood supply all at once. Meals that are lower in refined carbohydrates tend to cause less of a post-meal dip, since carbs trigger a stronger digestive blood flow response than protein or fat.
Use Caffeine Strategically
Coffee, tea, and other caffeinated drinks can raise blood pressure by 5 to 10 points in people who don’t consume them regularly. The effect kicks in within 30 minutes and can last up to two hours. If you’re prone to low blood pressure in the morning or after meals, a cup of coffee at those times can provide a temporary boost.
The catch is that regular caffeine drinkers build tolerance, so the blood pressure effect diminishes over time. If you already drink coffee daily and still have low blood pressure, adding more caffeine probably won’t help much. But if you’re not a habitual consumer, a well-timed cup can be a useful tool.
Try Physical Counter-Maneuvers
When you feel blood pressure dropping, especially when standing up, a few simple body movements can push it back up quickly. Crossing your legs while standing and squeezing your thighs together compresses the veins in your legs and forces blood back toward your heart. Clenching your fists repeatedly or tensing your abdominal muscles works through the same principle.
These maneuvers create a temporary increase in the pressure inside your blood vessels, buying you time until your body adjusts. They’re especially useful for orthostatic hypotension, the type where your pressure drops when you go from sitting to standing. Getting up slowly rather than jumping to your feet also gives your cardiovascular system more time to compensate.
Wear Compression Stockings
Compression garments prevent blood from pooling in your legs, which is one of the most common reasons blood pressure drops when you stand. Waist-high stockings rated at 20 to 30 mmHg or 30 to 40 mmHg of pressure are what most specialists recommend. Knee-high stockings help some, but waist-high versions are more effective because they compress a larger portion of your venous system.
They’re not the most comfortable option, especially in warm weather, but they make a real difference for people who get dizzy or lightheaded during prolonged standing. Put them on before getting out of bed in the morning, since that’s when pooling starts.
Check for Nutritional Deficiencies
Low blood pressure can sometimes be a symptom rather than the core problem. Deficiencies in vitamin B12 and folate can lead to a type of anemia where your body doesn’t produce enough healthy red blood cells. With fewer red blood cells carrying oxygen, your blood volume effectively drops, and your pressure falls with it.
Most adults need 2.4 micrograms of B12 and 400 micrograms of folate daily. B12 is found primarily in animal products like meat, fish, eggs, and dairy, which means vegetarians and vegans are at higher risk of deficiency. Folate is abundant in leafy greens, beans, and fortified grains. If you suspect a deficiency, a simple blood test can confirm it, and correcting the shortfall often improves blood pressure on its own.
Adjust Your Sleeping Position
Elevating the head of your bed by about 10 to 20 degrees (roughly 4 to 6 inches) can help with morning blood pressure drops. Sleeping on a slight incline encourages your body to retain a small amount of extra fluid overnight, which translates to higher blood volume when you wake up. This is particularly helpful if you tend to feel worst first thing in the morning or when getting out of bed.
Stacking pillows doesn’t achieve the same effect, since it bends your body at the waist rather than tilting your whole frame. Placing blocks or risers under the legs at the head of your bed creates the right angle.
