What to Do If Your Blood Pressure Is Low

If your blood pressure is reading below 90/60 mmHg and you’re feeling symptoms like dizziness, lightheadedness, or fatigue, there are several things you can do right now to bring it back up. Low blood pressure on its own isn’t necessarily a problem. Some people naturally run low without any issues. It only becomes a concern when it causes symptoms or drops suddenly enough to make you feel faint or unsteady.

What to Do Right Now During a Drop

If you feel your blood pressure dropping, meaning you’re getting dizzy, your vision is narrowing, or you feel like you might faint, the fastest thing you can do is change your position. Go from standing to sitting, or from sitting to lying down. Lying flat gives you an immediate bump in blood pressure because your heart no longer has to fight gravity to push blood to your brain.

If you can’t lie down, there are muscle-tensing techniques that work surprisingly well. Cross your legs while standing and squeeze the muscles in your legs, abdomen, and buttocks as hard as you can. Hold this until you feel better. Another option: grip one hand with the other and pull them apart without actually letting go, tensing your arms hard. You can also squeeze a stress ball (or just make a tight fist) in your dominant hand for as long as you’re able. These counter-pressure maneuvers force blood from your lower body back toward your heart and brain, and they can be enough to prevent a fainting episode.

Signs That Need Emergency Attention

Most low blood pressure episodes are uncomfortable but not dangerous. However, extremely low blood pressure can lead to shock, which is a medical emergency. Call 911 if you or someone around you develops confusion (particularly in older adults), cold and clammy skin, noticeable paleness, rapid shallow breathing, or a weak and fast pulse. These symptoms together suggest the body’s organs aren’t getting enough blood flow.

Drink More Fluids Than You Think You Need

Dehydration is one of the most common and most fixable causes of low blood pressure. When your blood volume drops, there simply isn’t enough fluid in your system to maintain pressure in your arteries. If you’re prone to low readings, aim for 2 to 3 liters of fluid per day. That’s roughly 8 to 12 cups. Water is the baseline, but beverages with electrolytes can help your body retain more of what you drink rather than flushing it straight through.

This is especially important in hot weather, after exercise, during illness involving vomiting or diarrhea, and first thing in the morning when you’ve gone hours without drinking anything. Many people with chronic low blood pressure notice their worst symptoms in the morning, partly because of overnight dehydration.

Salt Can Actually Help

For most health conditions, the advice is to cut back on salt. Low blood pressure is one of the rare exceptions. Salt helps your body hold onto water, which increases blood volume and raises blood pressure. If your readings run low, adding more salt to your meals or choosing higher-sodium foods may genuinely help. That said, too much sodium over time can strain your heart, so this is worth discussing with a doctor before making a significant dietary change, particularly if you’re older or have any history of heart problems.

Watch What Happens After Meals

Blood pressure commonly dips after eating, a phenomenon called postprandial hypotension. Your body diverts blood to your digestive system to process food, which can leave less circulating elsewhere. This tends to be worse after large meals and meals heavy in carbohydrates like bread, pasta, rice, and potatoes.

Two strategies help. First, eat smaller meals more frequently, six smaller meals instead of three large ones. Second, reduce the carbohydrate load in each meal. Combining protein, fat, and fiber with your carbs slows digestion and blunts the blood pressure drop. If you’ve noticed you feel especially dizzy or tired after lunch or dinner, this pattern is likely the reason.

Check Whether Your Medications Are the Cause

Several common medications lower blood pressure as either their intended effect or a side effect. Blood pressure medications themselves (including diuretics, beta blockers, calcium channel blockers, and ACE inhibitors) can overshoot and bring your numbers too low, especially if your dose was recently changed or you’ve lost weight. Antidepressants, medications for Parkinson’s disease, and drugs for erectile dysfunction can also cause drops, particularly when you stand up quickly.

If you suspect a medication is behind your low readings, don’t stop taking it on your own. Instead, keep a log of your blood pressure readings and symptoms and bring them to your next appointment. Your doctor can adjust the dose or timing, or switch you to an alternative.

Compression Garments for Ongoing Issues

If low blood pressure is a recurring problem, especially when you stand up (orthostatic hypotension), compression stockings can make a real difference. They work by gently squeezing your legs to prevent blood from pooling in your lower body. For blood pressure management, experts typically recommend waist-high stockings rated at 20 to 30 mmHg or 30 to 40 mmHg of pressure. Knee-high socks help some, but waist-high garments are more effective because they cover more surface area where blood tends to collect.

These can feel warm and tight, so many people wear them during the day and remove them at night. They’re most helpful if your symptoms are worst when you’re upright and on your feet for long periods.

Daily Habits That Keep Blood Pressure Stable

Beyond the immediate fixes, a few consistent habits reduce how often low blood pressure disrupts your day:

  • Get up slowly. When you wake up, sit on the edge of the bed for a minute before standing. When you’re getting up from a chair, pause halfway. Rushing from lying to standing is the most common trigger for a sudden drop.
  • Avoid prolonged standing. If you have to stand in one place for a long time, shift your weight, rock on your heels, or do the leg-crossing and muscle-tensing techniques described above.
  • Limit alcohol. Alcohol dilates blood vessels and lowers blood pressure. Even moderate amounts can trigger symptoms if you’re already prone to low readings.
  • Avoid very hot environments. Hot showers, saunas, and prolonged heat exposure all dilate blood vessels and pull blood pressure down. If you love hot showers, keep them short and have a chair nearby in case you feel lightheaded.
  • Eat and drink before physical activity. Exercise lowers blood pressure temporarily, so starting on an empty stomach or while dehydrated sets you up for symptoms.

Low blood pressure is manageable for most people once you understand your personal triggers. Tracking your readings at different times of day, before and after meals, and alongside your symptoms gives you a clear picture of what’s driving the drops and which strategies actually work for you.
