Many are interested in the question of why there is increased pressure in the morning after sleep. First of all, it is worth noting that during the day, depending on the food consumed, the level of physical activity, as well as the amount of emotional stress suffered. Unfortunately, for some people their blood pressure may be too high, especially in the morning. This is called morning hypertension.
Researchers have found that morning hypertension increases the risk of developing heart disease and problems with blood vessels. Moreover, even in patients with well-controlled blood pressure.
For pharmacists who treat such a diagnosis, it is very important to understand why the blood pressure rises in the morning. Also, this information is important to the patients themselves. Only if you know the exact reasons, you can decide on how exactly you can overcome this problem.
A normal reading at home should be less than 140/90 mm Hg. Systolic blood pressure (upper number) is the pressure created during the contraction of the heart. The diastolic blood pressure (lower number) is the pressure created when the heart is relaxed. The rate can be increased when the heartbeat is faster and heavier, or if the blood vessels constrict, making a narrower opening for the passage of blood.
What is the reason?
Usually, after waking up, the pressure level increases.
This is due to the normal circadian rhythm of the body.
The circadian rhythm is a 24-hour cycle that affects a person’s sleep and wakefulness.
In the morning, the body releases hormones such as adrenaline and norepinephrine.
These hormones give energy impulses, but can also increase blood pressure. In the morning, an increase in blood pressure is usually observed between 6:00 am and noon. If blood pressure rises too high, it can cause serious consequences. At the same time, the pulse of the heart muscle sharply increases.
Patients with hypertension, who also have hypertension, have a higher risk of developing stroke, compared with other patients with hypertension without morning hypertension. Especially when it comes to an older person. A stroke is a sudden loss of brain function due to insufficient blood supply. There are two types of stroke:
A stroke caused by a blood clot is called ischemic. It is the most common, accounting for 85% of the 600,000 strokes that occur every year. Hemorrhagic strokes occur when a blood vessel ruptures in the brain.
Morning hypertension can also increase the risk of other problems with the heart and blood vessels. This is due to changes in heart rate and size, which can lead to heart attack or heart failure. You should immediately contact your doctor if symptoms such as:
- Strong headache;
- chest pain;
- tingling on face or hands.
Of course, there is not one reason that leads to such a state. But everyone can minimize risks, for this purpose it is enough to measure their performance regularly.
Risk groups for the occurrence of morning hypertension
Doctors recommend that patients monitor their performance with a special device. Thus, it will be possible to determine the risk of morning hypertension.
Using a home blood pressure monitor, which has clinically proven its accuracy, you can find out your pressure level at any time and, if necessary, take the drug to normalize it.
The device can be purchased without a prescription at your local pharmacy. Several types of monitors are available, including automatic and manual models.
Automatic blood pressure monitors have the following advantages:
- Good memory features.
- Different sizes of cuffs.
- Electronic display that shows the date and time.
When buying a home blood pressure monitor, be sure to select the correct cuff size that matches the distance around the shoulder. If the wrong size of the cuff is used, it can cause an incorrect reading of the blood pressure. You also need to think in advance about what type of device is most appropriate in this situation.
At risk are most often people who have:
- high blood pressure (upper bar above 120 or 130);
- type 1 or type 2 diabetes;
- age over 65;
- there is a habit of smoking;
- craving for alcohol;
- high cholesterol.
If at least one of these signs is present, you need to be more attentive to your health.
How to use a home apparatus for measuring pressure?
Blood pressure should be checked in the morning, about an hour after a person wakes up, and in the evening, about an hour before going to bed. It is important to use the same hand each time. Carrying out 3 consecutive measurements in a period of one minute. In this case, you get a more accurate result. It is important to avoid caffeine or tobacco use at least 30 minutes prior to measurement.
The first thing you need to sit on a chair, in this case, the legs and ankles should not intersect, and the back properly supported. The hand must be at the same level as the heart, and rest on the table or counter.
You must always follow the user instructions that came with the device. You should also keep a log of all readings. Many monitors have built-in memory for recording readings, as well as fixing the date and time.
When visiting your doctor, it is advisable to take with you a log of testimony. Especially when it comes to hypertensive crisis. At the same time, one should fix his pressure not only in the evening, but also in the morning. And better several times a day.
But in order to understand exactly what relationship has sleep and high blood pressure, it is necessary to understand why this indicator rises and how to prevent such a result.
In medicine, one health condition is known, characterized by strong snoring and pauses in breathing at night.
Researchers at the John Hopkins School of Public Health conducted an experiment in which they found a link between snoring in sleep and high blood pressure.
The results of the study show that people who experience the largest number of pauses when breathing during sleep are twice as high as the usual risk of suffering from hypertension.
Some medicines can cause a temporary increase in blood pressure. If these drugs are taken in the morning, blood pressure may increase at the beginning of the day and fall in the evening.
It is known that corticosteroids used to treat diseases such as:
- Autoimmune pathology.
- Skin problems
- Severe allergies.
They cause an increase in blood pressure. Decongestants, especially those containing pseudoephedrine, also lead to a temporary increase in blood pressure. In this case, it can raise to 150 and above.
Also, a person’s work schedule can affect blood pressure in the morning. A study by Frank Scheer, his colleagues from Brigham of the Women's Hospital and Harvard University, confirms this statement.
In addition to the development of prediabetes, decreased insulin sensitivity and impaired glucose tolerance, some participants showed an increase in daily blood pressure levels, and by evening it was leveled.
What you need to remember?
Hypertension is usually diagnosed when several specific indications are found. This condition can increase the risk of strokes, heart attacks, kidney disease, heart attack in diabetes and other serious diagnoses.
If you do not take the drug for high blood pressure at night, it will lead to an increase in blood pressure. If hypertension is not controlled, the morning reading may be abnormally high.
The adrenal glands produce hormones that affect heart rate, blood flow and blood pressure. Epinephrine increases heart rate and relaxes the smooth muscles of the body. Norepinephrine does not have such a large effect on heart rate and smooth muscles, but increases blood pressure.
Adrenal tumors can cause overproduction of these hormones, increasing blood pressure. If norepinephrine is released in the morning, an increase in blood pressure can be noticed. In this case, the person often feels dizzy. Especially, if we are talking about a woman aged 50 years or more, as well as the elderly.
The use of tobacco and caffeine plays a role in increasing blood pressure levels. Tobacco use is one of the major risk factors for hypertension, since nicotine in tobacco products causes blood vessels to contract. This puts a strain on the heart, increasing blood pressure. Osteochondrosis has the same effect. It impairs blood circulation than contributes to the development of hypo-or hypertension.
If you do not regulate the negative factors that affect the development of the disease, intraocular or intracranial pressure may develop. And it usually ends very badly. Caffeine can also cause temporary pressure spikes, which means that a morning cup of coffee can cause an increase in blood pressure. Reducing caffeine intake can prevent a temporary increase in morning rates.
The reasons for the increase in blood pressure in the morning are described in the video in this article.
