Low blood pressure, defined as a reading below 90/60 mmHg, can often be managed at home through a combination of dietary changes, physical strategies, and simple habit adjustments. Most people with chronic low blood pressure don’t need medication. The right mix of salt, fluids, body positioning, and quick physical maneuvers can meaningfully raise your numbers and reduce symptoms like dizziness, fatigue, and lightheadedness.
Increase Your Salt and Fluid Intake
Salt is the single most effective dietary tool for raising blood pressure, because sodium pulls water into your bloodstream and increases blood volume. While most health advice tells people to eat less salt, the opposite applies here. Clinicians who treat orthostatic disorders (conditions where blood pressure drops when you stand) routinely recommend more than 2,300 mg of sodium per day. The Canadian Cardiovascular Society recommends about 4,000 mg of sodium daily for these patients, and a Heart Rhythm Society consensus statement suggests 4,000 to 4,800 mg per day for people with conditions like POTS. For context, the average American consumes around 3,400 mg, so you may need to deliberately add salt to your meals.
Practical ways to get more sodium include salting your food generously, eating pickles, olives, broth, and salted nuts, or adding electrolyte packets to your water. Some people find it easier to add 1,000 to 2,000 mg of sodium to three meals throughout the day rather than trying to hit a large number all at once.
Fluids matter just as much as salt. Water alone won’t stay in your bloodstream efficiently without adequate sodium, so the two work together. Aim for at least 2.7 to 3.7 liters of total fluid per day from all sources, including food. Keeping a water bottle with you and sipping consistently throughout the day is more effective than drinking large amounts at once.
Use Physical Counter-Pressure Maneuvers
When you feel dizzy or lightheaded, specific muscle-tensing movements can raise your blood pressure within seconds. These work by squeezing your blood vessels through muscle contraction, pushing blood back toward your heart and brain. A meta-analysis found that these maneuvers improved standing systolic blood pressure by nearly 15 mmHg on average, which is a significant boost when you’re feeling faint.
The most effective techniques include:
- Leg crossing with tensing: Cross your legs at the ankles while standing and squeeze your thigh and calf muscles together.
- Squatting: Drop into a full squat if you feel a dizzy spell coming on. This is one of the fastest ways to restore blood pressure. When you stand back up, tense your leg muscles to prevent the pressure from dropping again.
- Hand gripping: Squeeze a ball or make a tight fist and hold it for 15 to 30 seconds.
- Whole-body tensing: Tighten your arms, legs, and core muscles simultaneously while standing.
These are especially useful in situations where you can’t sit down immediately, like standing in line or getting out of bed. If you feel severely lightheaded, the “crash position” (squatting with your head between your knees) is the most reliable way to quickly restore blood flow to your brain.
Eat Smaller, Lower-Carb Meals
Blood pressure naturally drops after eating because your body diverts blood to your digestive system. This effect, called postprandial hypotension, is worse after large meals and meals high in carbohydrates. White bread, pasta, rice, and sugary foods tend to cause the sharpest drops.
Switching from three large meals to six smaller ones throughout the day reduces the amount of blood your gut demands at any one time. Keeping those meals lower in refined carbohydrates and higher in protein and fat helps further. You don’t need to eliminate carbs entirely, just avoid eating a large plate of pasta as your entire meal. Pairing carbohydrates with protein, fat, or fiber slows digestion and blunts the blood pressure dip.
Limit or Avoid Alcohol
Alcohol dilates blood vessels in your gut without increasing your heart’s output to compensate, which lowers blood pressure while you’re sitting or lying down. It also makes the drop worse when you stand up. Research on patients with autonomic conditions found that alcohol caused blood pressure to fall further during head-up tilting, with no helpful increase in the stress hormones that would normally counteract that drop. If you already run low, even one or two drinks can trigger symptoms. Reducing or eliminating alcohol is one of the simplest changes you can make.
Wear Compression Garments
Compression stockings prevent blood from pooling in your legs when you stand, which is one of the main reasons blood pressure drops in the upright position. The key details matter here: experts in dysautonomia recommend 20 to 30 mmHg or 30 to 40 mmHg pressure ratings, and they should be waist-high rather than knee-high. Knee-high stockings only compress your calves, allowing blood to pool in your thighs. Full-length compression covers the largest reservoir of venous blood in your lower body.
Abdominal compression binders are another option, particularly if you find full-length stockings uncomfortable. They work by the same principle, squeezing blood out of the large venous beds in your abdomen. Some people combine both for maximum effect.
Elevate the Head of Your Bed
Sleeping with your head raised about 9 to 12 inches (roughly a 10-degree tilt) helps your body retain fluid overnight and reduces the sharp blood pressure drop many people experience when getting out of bed in the morning. The mechanism is subtle: a slight tilt activates your kidneys’ fluid-retention signals during sleep, so you wake up with more blood volume.
You can achieve this by placing bed risers or blocks under the legs at the head of your bed, or by using a wedge pillow. The goal is to tilt your entire upper body, not just prop your head up with regular pillows, which can bend your neck uncomfortably without actually raising your torso enough to matter.
Change Positions Slowly
Many low blood pressure symptoms hit hardest during transitions: getting out of bed, standing up from a chair, or rising after bending down. Moving slowly gives your cardiovascular system time to adjust. When waking up, sit on the edge of the bed for 30 seconds to a minute before standing. When getting up from a chair, pause in the standing position and tense your leg muscles before walking. These small delays let your blood vessels constrict and your heart rate increase enough to maintain adequate blood flow to your brain.
Combining slow transitions with counter-pressure maneuvers (like leg crossing and tensing as you stand) provides two layers of protection against dizziness. Over time, these habits become automatic and significantly reduce the frequency of symptomatic episodes.
