What does high blood pressure in the morning mean?

Many people have abnormally high blood pressure in the morning

Blood pressure fluctuates naturally throughout the day and tends to increase around the time a person wakes up. However, for many people, blood pressure may be abnormally high in the mornings. Doctors refer to this as morning hypertension.
Morning hypertension can increase the risk of heart attack and stroke. These medical emergencies often occurTrusted Source in the early hours when blood pressure rises. In this article, we explore the causes and effects of morning hypertension. We also look at ways in which people can prevent and control this condition.


Some potential causes of morning hypertension include those below.


Some people take antihypertensive medications to control their blood pressure. According to a 2018 reviewTrusted Source, uncontrolled morning hypertension may indicate a problem with the type or dosage of these medications. Specifically, morning hypertension may be due to one or more of the following factors:
  • taking a medication dosage that is too low
  • taking short-acting or intermediate-acting medications rather than long-acting medications
  • taking a single antihypertensive medication rather than a combination of medications
Some people may find that taking their medications before bed rather than in the morning provides better blood pressure control. Others may need to split their daily dose, taking half in the morning and half before bed. In some cases, a person may need to change to another type of blood pressure drug altogether. It is important to speak to a doctor before making any changes to medications.

Medical conditions

Certain medical conditions may increase the risk of hypertension. These include:
  • untreated high blood pressure
  • high cholesterol
  • cardiovascular disease
  • obstructive sleep apnea
  • diabetes
  • thyroid disorders
  • Cushing’s syndrome
  • lupus
  • scleroderma
  • kidney disease

Lifestyle factors

Certain lifestyle factors can also increase the risk of hypertension. Examples include:
  • smoking
  • heavy alcohol consumption
  • eating a diet high in salt and saturated fat
  • not getting enough exercise

Who is at risk?

The following factors can increase a person’s risk of developing morning hypertension:
  • being over the age of 65 years
  • being of African or Caribbean descent
  • having a relative with high blood pressure
  • having overweight or obesity
  • drinking alcohol
  • smoking
  • anxiety or excessive stress
  • insufficient sleep
  • disturbed sleep, for example, working night shifts

The function of blood pressure in the body

Circulation is similar to a highly sophisticated form of plumbing — blood has “flow,” and arteries are “pipes.” A basic law of physics gives rise to blood flow, and this law also applies in a garden hose pipe. Blood flows through the body because of a difference in pressure. Blood pressure is highest at the start of its journey from the heart — when it enters the aorta — and it is lowest at the end of its journey along progressively smaller branches of arteries. That pressure difference is what causes blood to flow. Arteries affect blood pressure in a similar way to the physical properties of a garden hose pipe affecting water pressure. Constricting the pipe increases pressure at the point of constriction. Without the elastic nature of the artery walls, for example, the pressure of the blood would fall away more quickly as it is pumped from the heart. While the heart creates the maximum pressure, the properties of the arteries are just as important to maintaining it and allowing blood to flow throughout the body. The condition of the arteries affects blood pressure and flow, and narrowing of the arteries can eventually block the supply altogether, leading to dangerous conditions including stroke and heart attack.
