To avoid raising blood pressure quickly, don't drink excess alcohol, sugary sodas, energy drinks, or large amounts of caffeine (coffee/tea), as these can cause temporary spikes or contribute to long-term hypertension, and be cautious with grapefruit juice if on medication; instead, focus on water, unsweetened tea, or low-sodium juices.
Just remember that natural sugars are found in fruit, vegetable, and milk-based drinks. Watch out for added sugars in sweetened beverages such as energy drinks, regular sodas, and flavored teas, which may increase blood pressure and heart disease risk.
High blood pressure in pregnancy is generally defined as a systolic (top number) reading of 140 mmHg or higher, or a diastolic (bottom number) reading of 90 mmHg or higher, confirmed on two occasions at least four hours apart, and developing after 20 weeks of pregnancy without a prior history of hypertension. This condition, known as gestational hypertension, differs from chronic hypertension (pre-existing high BP) or preeclampsia (high BP with signs of organ damage like protein in urine), and requires close monitoring.
Even if your child takes medication for high blood pressure, lifestyle changes can make the medication work better.
4 foods to avoid with high blood pressure
Eating too much sodium—an element in table salt—increases blood pressure. Most of the sodium we eat comes from processed and restaurant foods. Not eating enough potassium—a mineral that your body needs to work properly—also can increase blood pressure.
Key Takeaways. An extreme spike in blood pressure, especially to 180/120 mmHg or higher, can trigger a sudden stroke. Long-term high blood pressure increases the risk of stroke.
Take it first in the morning before eating or taking any medicine. Take it again in the evening. Each time you measure, take two or three readings to make sure your results are the same.
During episodes of acute anxiety or panic attacks, it's not uncommon for systolic blood pressure to increase by 20 to 30 mmHg or more. These spikes are typically temporary, but they highlight the significant impact that our emotional states can have on physical health.
What causes high blood pressure?
Stage 1 hypertension.
The top number is between 130 and 139 mm-Hg or the bottom number is between 80 and 89 mm-Hg.
Common causes of high blood pressure spikes
120 to 129 and above 80 mm Hg: elevated blood pressure. 130 to 139 and 80 to 89 mm Hg: stage 1 hypertension. 140 or more and 90 mm Hg or more: stage 2 hypertension. 180 or more and 120 mm Hg or higher: an emergency.
Crisps and salty snacks
Salty snacks such as crisps and crackers are not the best idea if you're looking to lower your blood pressure. Not only do snacks such as these contain high amounts of sodium and fat, but they're also very moreish, meaning it's difficult to stop eating them once you start.
Heart-healthy drinks (other than water)
Most experts will tell you the very first thing you should reach for is water. It is natural, it contains all the elements that our bodies are craving but for many people it's one of the last things they consider after options such as tea, coffee, hot chocolate, milk, and fruit juices.
Relax. Before you measure your blood pressure, take a few deep breaths, sit quietly by yourself, and make sure your legs and ankles are not crossed. Keep your arm at heart level. Make sure you're seated in an upright position and place the blood pressure cuff directly on the skin at the level of your heart.
Experts think that sleep helps the body control hormones needed to control stress and metabolism. Over time, a lack of sleep could cause swings in hormones. Hormone changes can lead to high blood pressure and other risk factors for heart disease.
By sifting through data from hundreds and thousands of people, the researchers were able to link a higher systolic blood pressure with increased anxiety and neuroticism and a higher diastolic blood pressure with increased neuroticism alone.
Stretch out your arm, palm upward. Place the cuff on your bare upper arm one inch above the bend of your elbow. Make sure the tubing falls over the front center of your arm so that the sensor is correctly placed. Pull the end of the cuff so that it's evenly tight around your arm.
Choosing a home blood pressure monitor
Wrist and finger monitors are not recommended. They give less reliable readings. Choose a monitor that has been validated. If you are unsure, ask your health care professional or pharmacist for advice or find options at validatebp.org(link opens in new window).
The 60-second trick to lower blood pressure involves deep, controlled breathing, often called "square breathing," where you inhale for 4-5 seconds, hold for 4-5, and exhale for 4-5, repeating to calm your nervous system and slow heart rate, alongside other quick tactics like sipping water, splashing your face with cold water (mammalian dive reflex), or gentle movement. While these provide quick relief, remember consistent lifestyle changes are key for long-term management, and severe spikes need medical attention.
Other signs and symptoms may include:
A blockage of a blood vessel in the brain or neck, called an ischemic stroke, is the most frequent cause of stroke and is responsible for about 80 percent of strokes.
In other words, once blood pressure rises above normal, subtle but harmful brain changes can occur rather quickly—perhaps within a year or two. And those changes may be hard to reverse, even if blood pressure is nudged back into the normal range with treatment.
