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.
Use the blood pressure chart below to see what your blood pressure means. The blood pressure chart is suitable for adults of any age. (The level for high blood pressure does not change with age.) Blood pressure readings have two numbers, for example 140/90mmHg. The top number is your systolic blood pressure. (The highest pressure when your heart beats and pushes the blood round your body.) The bottom one is your diastolic blood pressure. (The lowest pressure when your heart relaxes between beats.) The blood pressure chart below shows ranges of high, low and healthy blood pressure readings.
