Patients with hypertension are so sensitive to the external environment that a little movement will cause a rise in blood pressure, even if they smoke a cigarette or inhale secondhand smoke.

Hypertension generally refers to essential hypertension, accounting for more than 90% of hypertension, is the most common chronic disease, but also one of the biggest hidden dangers of cardio-cerebrovascular diseases.

The serious cause of hypertension is not the disease itself, but a series of serious complications, including stroke, myocardial infarction, heart failure and chronic kidney disease.

I believe that many patients with hypertension have heard the doctor's advice that high blood pressure must not smoke!Smoking will not only harm the health of the lungs, but also cause serious hypertension and even more serious cardiovascular disease!

Medicine has confirmed that when each cigarette burns, it releases more than 4000 chemicals and billions of particles, including 69 carcinogens such as nicotine, carbon monoxide, tar, ammonia and benzene.

A large number of harmful substances in tobacco are inhaled into the human body, which will adhere to the trachea wall and alveoli, which can easily lead to tracheitis, emphysema and even lung cancer, in which carbon monoxide can significantly reduce the content of oxygen in the blood and easily cause cardiovascular and cerebrovascular diseases such as hypertension.

What is hypertension?

The human heart is equivalent to a blood pump, transporting the blood in the heart to every corner of the body, through a large number of large and small blood vessels in the body, relying on rhythmic mechanical movement of relaxation and contraction, constantly transporting blood through blood vessels to organs of the whole body, supplying oxygen, taking away waste, and ensuring the metabolism of the body.

During continuous contractile exercise, the lateral pressure of blood flow in blood vessels on the wall of blood vessels per unit area is called blood pressure.

There are three kinds of blood pressure: arterial blood pressure, venous blood pressure and capillary blood pressure. arterial blood pressure is generally measured in hospitals, while the daily sphygmomanometer generally refers to capillary blood pressure.

The biggest feature of hypertension is strong concealment, in the early stages of the disease, most patients will not have any discomfort, the body looks very quiet, but the body is "undercurrent".

The shear stress of vascular wall caused by elevated blood pressure will increase, thus aggravating the damage of vascular endothelium, and once the vascular endothelium is damaged, the arterial stiffness increases, vascular elasticity decreases, and arteriosclerosis gradually forms.

Pathogenesis of hypertension.

Since hypertension is random, once triggered by external media, it will cause an increase in blood pressure.This should be a normal stress response, but how can there be hypertension?
High blood pressure triggered by the external environment will calm down after the stimulus disappears.

However, the blood pressure of patients with hypertension has been high, vascular hypertension will seriously damage blood vessels, and even endanger the heart, brain, kidney and other important organs, and finally lead to a series of serious hypertension complications.

There are no more than two pathogenic factors of hypertension, the first is essential hypertension, that is, blood vessels lack certain nutrients, which leads to vascular stiffness, slow loss of elasticity, and difficulties in blood transportation. at this time, the heart has to increase pressure to transport blood, which leads to high blood pressure.

The second is secondary hypertension, if the triglyceride and cholesterol in the blood are too high, the blood viscosity is too high, the speed of blood flow becomes slower, a lot of attachments will be deposited on the blood vessels, and the blood can not pass smoothly, which will lead to hypertension.

Smoking causes high blood pressure.

Smoking increases blood pressure, which is mainly related to nicotine in tobacco leaves.Nicotine excites the central and sympathetic nerves, which speeds up the heart rate and the heart's contraction and relaxation, which in turn leads to high blood pressure.

In addition, the adrenal gland releases large amounts of catecholamines.

Catecholamine can contract arterioles and increase peripheral vascular resistance,resulting in a rapid rise in blood pressure.Experiments have shown that after smoking a cigarette,the human heart rate increases by an average of 5 to 20 beats per minute,and systolic blood pressure increases by 10~25mmHg.

When the human body smokes two cigarettes, about 10 minutes later, the secretion of epinephrine and norepinephrine increases, the heart beats faster, and both systolic and diastolic blood pressure rise correspondingly.

This increase in blood pressure is an one-off, and when factors such as nicotine in the body that cause the increase in blood pressure lose their influence, the blood pressure will return to normal.

But this does not mean that smoking has nothing to do with high blood pressure, which can have a chronic effect on the body and eventually lead to high blood pressure for a long time, or complications for people who already have high blood pressure.
Long-term heavy smoking will also promote atherosclerosis in large arteries, and the intima of small arteries thickens one by one, making the whole blood vessels gradually hardened.

In addition, the content of carbon monoxide hemoglobin in the blood of smokers increases, which reduces the oxygen content of hemoglobin to a certain extent, makes the arterial intima anoxic, increases the oxygen content of the arterial wall, and accelerates the formation of atherosclerosis.

What's more,everyone should pay attention to their own blood pressure health.To do that,wearing a BP smart watch which can monitor blood pressure everywhere when need is so important.
