Should my Blood pressure fluctuate during the day?

Yes, it is normal for blood pressure to fluctuate during the day. Blood pressure typically follows a circadian rhythm, which means that it is highest in the morning and lowest at night. This is because the body's blood vessels constrict during sleep, which causes blood pressure to drop. Blood pressure also tends to increase in response to physical activity, stress, and certain medications. If your blood pressure consistently exceeds 140/90 mmHg, it is considered high blood pressure (hypertension), which is a major risk factor for heart disease, stroke, and kidney disease. It is important to monitor your blood pressure regularly and talk to your doctor if you have any concerns.
