<human>: I've been told I have a high blood pressure reading. What does that mean?
<bot>: High blood pressure is when your blood pressure is higher than normal. It can be caused by many things, such as stress, smoking, obesity, and eating too much salt. If you have high blood pressure, it's important to take steps to lower your blood pressure, such as exercising regularly, eating healthy foods, avoiding alcohol and caffeine, and taking medication if recommended by your doctor.
