Blood pressure is the force of blood as it pushes against the blood vessel walls. According to the latest guidelines, healthy blood pressure measurements should be at least 90/60 millimeters of mercury (mm Hg) and less than 120/80 mm Hg. Blood pressure readings can be influenced by exercise, stress, sleep, medications, and supplements. In most cases, blood pressure is lowest in the morning and highest in the middle of the afternoon. Typically, it decreases in the late afternoon and evening. Anxiety and night-shift work can both increase the risk of developing high blood pressure. Patients who have borderline high readings should have their blood pressure checked by a doctor at least once a year.
Some patients may want supplements for high blood pressure. However, high blood pressure pills are only recommended when patients have readings of 140/90 mm Hg or higher. Many individuals will attempt natural remedies for high blood pressure as well. Of course, patients should talk to their doctors first. Sometimes, certain medications and supplements will raise blood pressure instead.
Some studies suggest that caffeine increases blood pressure in certain individuals. This applies to when it is in beverage or capsule form. Caffeine makes the blood vessels constrict, and this mechanism elevates blood pressure. Some individuals who regularly consume caffeine tend to have higher than average blood pressure measurements. However, others who consume caffeine regularly develop a tolerance for it. Thus, they do not experience elevations in their average blood pressure readings. Temporary elevations in blood pressure have been observed in study participants who consume two to three hundred milligrams of caffeine.
Researchers suggest that patients limit their daily caffeine intake to no more than two hundred milligrams. Hypertension patients should avoid consuming caffeine immediately before exercising or performing other activities that naturally raise blood pressure. Patients should check with their doctor to find out if it is safe for them to consume caffeine.
