Before measuring your blood pressure, do not eat, smoke, or exercise for at least 30 minutes. Do not use any medications that can raise blood pressure. Rest for at least 5 minutes before taking the reading. Sit in a comfortable position with both feet flat on the floor. Do not move or talk while measuring your blood pressure. Try not to measure your blood pressure if you are stressed or upset. If possible, use the same arm for each reading. Readings may differ by 10 to 20 mmHg between arms. Remember that blood pressure readings vary throughout the day. They are usually highest in the morning after you wake up and move around. They decrease during the day and are at their lowest in the evening. When you first start measuring your blood pressure, always take three readings. Wait one to two minutes between recordings to allow blood to flow back into your arm. Once you get better at doing this, you'll probably only need to do it once or twice at a time.
