A normal blood pressure reading is typically between 90/60 and 120/80 millimeters of mercury (mm Hg). Your doctor may diagnose you with low blood pressure if your reading is under 90/60 mm Hg and have other symptoms – blurred vision, fainting, dizziness, lightheadedness.

What to eat

Eating certain types of food can help you raise your blood pressure. 

Salt - Salty foods can increase blood pressure. Try eating food items high on sodium like pickled items.

More fluids - Dehydration decreases blood volume, causing blood pressure to drop. Staying hydrated is especially important when exercising.

Caffeine - Coffee and caffeinated tea may temporarily spike blood pressure by stimulating the cardiovascular system and boosting your heart rate.

Foods high in vitamin B-12 - Too little vitamin B12 can lead to a certain type of anemia, which can cause low blood pressure and fatigue. Foods high in B-12 include eggs, fortified cereals, animal meats, and nutritional yeast.

Foods high in folate - Too little folate can also contribute to anemia. Examples of folate-rich foods include beans, lentils, citrus fruits, leafy greens, eggs, and liver.

Other lifestyle changes

Eat small meals more frequently - Large meals may cause more dramatic drops in blood pressure, as your body works harder to digest larger meals.

Drink more water and limit alcohol - Dehydration lowers blood pressure.

If you exercise outdoors in extreme heat, take frequent breaks and be sure to increase hydration efforts.

Avoid prolonged bed rest. While getting up from bed, stand up slowly.
