If your blood pressure drops below 90/60 mmHg and you’re feeling symptoms like dizziness, lightheadedness, or faintness, there are several things you can do right away and over time to bring it back up. Some people naturally run low without any problems, so the number alone isn’t always a concern. What matters is whether you’re feeling it.
What to Do Right Now
If you feel dizzy or lightheaded while standing, cross your thighs like a pair of scissors and squeeze them together. This pushes blood from your legs back toward your heart and can raise your pressure within seconds. Another option: put one foot up on a chair or ledge and lean forward as far as you can. Both of these moves work by redirecting pooled blood upward.
If you can, sit or lie down. Elevating your feet above the level of your heart helps even more. Drink a full glass of water, since low fluid volume is one of the most common and fixable causes of low blood pressure. When you’re ready to stand again, do it slowly. Move from lying to sitting first, pause for a moment, then rise to your feet. Rushing through position changes is one of the fastest ways to trigger a drop.
Why Your Blood Pressure Might Be Low
Dehydration is the simplest explanation. When you lose fluid through sweating, illness, or just not drinking enough, your blood volume drops and your blood pressure follows. General fluid guidelines suggest roughly 125 ounces (about 3.7 liters) per day for men and 91 ounces (2.7 liters) for women, though individual needs vary with activity level and climate.
Medications are another major cause. Blood pressure drugs like ACE inhibitors, calcium-channel blockers, and beta-blockers can overshoot their target and push your pressure too low, especially when you first start them or increase the dose. Antidepressants (SSRIs) and certain prostate medications (alpha-blockers) also commonly cause drops, particularly when you stand up. If you recently started or changed a medication and noticed new dizziness, that’s worth flagging to whoever prescribed it.
Other triggers include prolonged bed rest, significant blood loss, severe infection, heart conditions, and hormonal problems like adrenal insufficiency. Pregnancy commonly lowers blood pressure, especially in the first and second trimesters. Standing for long periods in hot weather can also pull blood into your legs and away from your brain.
Eating Habits That Help
Blood pressure typically hits its lowest point 30 to 60 minutes after a meal, a phenomenon called postprandial hypotension. Large meals cause bigger drops than smaller ones, so eating smaller, more frequent meals throughout the day can make a noticeable difference.
The type of food matters too. White bread, white rice, potatoes, and sugary drinks pass quickly from your stomach to your small intestine, and this rapid transit pulls blood pressure down. Swapping those for whole grains, beans, protein, and healthy fats slows digestion and keeps your pressure more stable. Drinking 12 to 18 ounces of water about 15 minutes before eating can also blunt the post-meal drop. If you still feel symptomatic after meals, sitting or lying down for an hour afterward is a practical workaround.
Longer-Term Strategies
Staying well hydrated day to day is the foundation. Adding a bit more salt to your diet can also help, since sodium holds onto water in your bloodstream and increases blood volume. This is one of the rare situations where extra salt is a good thing, though you should check with your doctor first if you have heart or kidney issues.
Compression stockings that reach the upper thigh, with a pressure rating of 23 to 32 mmHg, can prevent blood from pooling in your legs. They’re especially useful if your pressure tends to drop when you stand (orthostatic hypotension), which affects an estimated 7% to 10% of adults with high blood pressure and is even more common in older adults. Waist-high abdominal binders work on the same principle. These aren’t glamorous solutions, but they’re effective for people who deal with frequent symptoms.
Avoid standing still for long stretches. If you have to, shift your weight, flex your calf muscles, or rock on your heels. Sleeping with the head of your bed elevated a few inches (rather than flat) can also help your body adjust to upright positions more smoothly in the morning.
When Low Blood Pressure Needs Medical Attention
Occasional mild dizziness when you stand up too fast is common and usually harmless. But if you’re experiencing fainting episodes, confusion, blurred vision, cold or clammy skin, rapid shallow breathing, or a weak and fast pulse, those are signs your organs aren’t getting enough blood flow. That combination of symptoms needs urgent medical evaluation.
Persistent low blood pressure that interferes with your daily life also warrants a visit. Your doctor may review your medications, check for underlying causes like anemia or thyroid problems, or adjust your treatment plan. In cases of severe orthostatic hypotension caused by nervous system dysfunction, where lifestyle changes aren’t enough, there are prescription medications that work by tightening blood vessels or increasing blood volume. These are typically reserved for people whose symptoms significantly limit their ability to function.
What You Don’t Need to Worry About
If your blood pressure consistently reads on the low side but you feel fine, there’s generally nothing to fix. Many healthy, active people run below 90/60 their entire lives without any issues. Athletes, in particular, often have naturally low resting blood pressure. The number only becomes a problem when it causes symptoms or drops suddenly from where it normally sits. A blood pressure reading is a snapshot, not a diagnosis on its own.
