A 24‑hour blood pressure monitor is a small device you wear for one day and night to check your blood pressure during normal daily activities and while you sleep. It uses a cuff on your arm that automatically takes readings throughout the day and night. This gives a more accurate picture thana single reading at the clinic. The monitor helps doctors see if your blood pressure is only high at appointments or high all the time, and whether your medication is working well. You can do most normal activities while wearing it, but keep your arm still when it takes a reading. After 24 hours, you return the monitor so your health‑care team can review the results and plan the best care for you.
