If your blood pressure consistently reads below 90/60 mmHg and you’re experiencing dizziness, fatigue, or lightheadedness, there are several proven ways to bring it up. The approach depends on whether you need a quick fix in the moment or a longer-term strategy to keep your numbers stable throughout the day.
Quick Physical Tricks That Work Immediately
When you feel lightheaded or sense your blood pressure dropping, specific muscle-tensing techniques can raise your systolic pressure by roughly 15 mmHg within seconds. These work by squeezing blood out of your leg and abdominal veins and pushing it back toward your heart, increasing the volume of blood your heart pumps with each beat.
The most effective maneuvers, ranked by how strongly they raise blood pressure:
- Crossing your legs and tensing them simultaneously. This produces the largest blood pressure increase of any standing maneuver.
- Crossing your legs while standing (even without actively tensing) is nearly as effective.
- Gripping something hard or tensing your arms. Upper limb tensing raises both blood pressure and heart rate substantially.
- Squatting. Very effective in the moment, but be careful standing back up. The blood pressure boost disappears quickly when you rise, and some people feel worse during the transition.
- Tensing your abdominal muscles, doing calf raises, or marching in place. These produce a smaller but still meaningful effect.
A meta-analysis in Frontiers in Cardiovascular Medicine found that about 72% of people who used these techniques in daily life reported symptom improvement. One important caution: don’t hold your breath or bear down while tensing. That straining action increases pressure inside your chest and actually reduces blood flow to your heart, making things worse.
Increase Your Salt Intake
For most health conditions, doctors tell you to cut salt. Low blood pressure is the exception. Salt pulls water into your bloodstream, expanding your blood volume and raising pressure. Medical guidelines for people with orthostatic hypotension (the kind where you get dizzy standing up) recommend 2,400 to 4,000 mg of sodium per day at a minimum. Some specialists push that to 4,000 to 8,000 mg daily for more stubborn cases. For context, the average American consumes about 3,400 mg.
A practical approach is to add 1,000 to 2,000 mg of sodium to your diet three times per day. You can do this with salty snacks, broth, pickles, olives, or sodium tablets. Pair the extra salt with plenty of water, since salt only raises blood pressure when there’s enough fluid for it to retain.
Drink More Water and Use Caffeine Strategically
Dehydration is one of the most common and fixable causes of low blood pressure. Even mild dehydration reduces blood volume, making it harder for your body to maintain pressure when you stand. Drinking 16 ounces of water can produce a noticeable blood pressure increase within minutes, especially first thing in the morning when you’re naturally dehydrated from sleep.
Caffeine offers a reliable short-term boost. A cup of coffee or tea raises systolic blood pressure by 3 to 15 mmHg and diastolic by 4 to 13 mmHg. The effect kicks in within 30 minutes, peaks at one to two hours, and can last more than four hours. If your low blood pressure is worst in the morning, a cup of coffee before you start moving around can help bridge the gap. Keep in mind that regular caffeine drinkers may develop some tolerance, so the effect can be smaller over time.
Eat Smaller, More Frequent Meals
Large meals can cause a surprising drop in blood pressure. After you eat, your body diverts blood to your digestive system. Normally, your heart rate increases and blood vessels elsewhere tighten to compensate. But if that response is sluggish, your blood pressure falls. This is called postprandial hypotension, and it’s especially common in older adults.
The fix is straightforward: eat six smaller meals throughout the day instead of three large ones. Smaller meals require less blood flow to digest, so the compensatory demand on your cardiovascular system is lower. Reducing simple carbohydrates at each meal also helps, since carbs tend to trigger the largest blood pressure drops.
Wear Compression Stockings
Compression stockings squeeze blood out of your lower legs and back toward your heart, preventing the pooling that causes blood pressure to drop when you stand. Knee-high stockings rated at 20 to 30 mmHg of compression at the ankle are commonly used. Some stockings deliver more compression than their packaging suggests, so they may feel quite tight at first.
For best results, put them on before you get out of bed in the morning, since that’s when blood pooling is most likely to cause problems. Waist-high compression garments or abdominal binders provide additional benefit if knee-high stockings alone aren’t enough, since a significant amount of blood pools in the abdomen as well.
Change Positions Slowly
Many people with low blood pressure feel worst when transitioning from lying down to standing. A few simple habits reduce that drop. Sit on the edge of your bed for 30 to 60 seconds before standing. Pump your ankles up and down several times while seated to activate the calf muscles that push blood upward. When you do stand, use one of the leg-crossing or tensing maneuvers described above for the first 30 seconds.
When Lifestyle Changes Aren’t Enough
If salt, water, compression, and physical maneuvers don’t adequately control your symptoms, prescription medications can help. The two most commonly prescribed options work through different mechanisms. One increases blood volume by helping your kidneys retain sodium and water. The other directly tightens blood vessels to raise resistance and push pressure up. A third option works by boosting levels of a natural hormone that raises blood pressure. All three require monitoring for side effects like elevated blood pressure when lying down, so they’re typically started at low doses and adjusted over time.
Medications are generally reserved for people whose symptoms significantly affect daily life, since the lifestyle strategies above are effective for the majority of people with mild to moderate low blood pressure.
