The Apple iPhone SE is a development of the 5S, taking the same design but refining it slightly with features such as matte edges. It measures 123.8 x 58.6 x 7.6mm and hits the scales at 113g. This means the iPhone SE is slimmer and smaller than the iPhone 5C and the same size as the iPhone 5S.
Both numbers are important to your heart health. A normal blood pressure reading will clock in below 120/80. To put it another way, your systolic will be below 120 and your diastolic will be below 80. (Low blood pressure, called hypotension, occurs when your reading measures lower than 90/60.
Blood pressure readings can fall into one of five categories: 1  Prehypertension. If your systolic blood pressure is between 120-139 mm Hg or if your diastolic blood pressure reading is between 80 and 89 mm Hg, you may have prehypertension. Prehypertension, like high blood pressure, carries an increased risk of cardiovascular disease and typically worsens over time.
