Summer hypertension patients have high blood pressure?Don't be "fooled" by blood pressure!

Every summer, my high blood pressure is high and low. The blood pressure is very low during the day, and the blood pressure rises again at night. Should I take this medicine or not to eat it.

Uncle, you must use the doctor's advice. You must not be "flickered" by high blood pressure in summer.

{Summer blood pressure is low? }

Blood pressure is closely related to changes in temperature. Regardless of individuals or patients with normal age or blood pressure, blood pressure can show seasonal changes.

Hypertensive patients have high blood pressure in winter and low blood pressure in summer. The reason may be due to:

01

In a cold environment, blood vessel contraction and peripheral resistance increased, and in a warm environment, blood vessel dilation and peripheral resistance decreased, which reduced blood pressure;

02

When the weather is hot, the body's water evaporation increases and the sweating increases, resulting in the increase in salt loss and the decrease in blood capacity, which may further lead to a decrease in summer blood pressure;

03

The reduction of ultraviolet strength in winter is related to the increase in the secretion of vitamin D reserves and the increase in thyroid hormone secretion. The secretion of thyroid gonads can stimulate the growth of vascular smooth muscle, and enhances its shrinkage by affecting the reaction of intracellular calcium, adrenaline reactability and/or endothelial function. And summer is just the opposite;

04

It is related to the time of sunlight, which may be mediated by melatonin affecting adrenaline, corticosteroids and prolactin.

{What impact will blood pressure changes in summer? }

Epidemiological studies have shown that high temperature will increase the hospitalization rate and mortality of patients with high blood pressure. Among them, the elderly are the most obvious group affected by high temperature. Summer is the high incidence of cardiovascular and cerebrovascular incidents in elderly patients, which is significantly higher than spring and autumn. The incidence is equivalent to winter.

When the environmental temperature of the summer rises, the human body starts the environmental adaptation mechanism, showing that the heart rate is accelerated, the amount of heart emission is increased, the skin vascular dilation, the increase in blood flow, and a large amount of sweat and heat dissipation. Elderly patients with high blood pressure sweat more and cause loss of water and salt, decreased blood capacity, increased blood viscosity, and can easily occur. Therefore, the early morning stroke and myocardial infarction incidence of patients with hypertension in the summer are significantly higher than other seasons.

{The lower the blood pressure value, the better? }

In fact, the lower the blood pressure value is not as good as possible.

On the one hand, the low blood pressure value causes insufficient blood perfusion of the whole body to cause insufficient blood supply to the cerebral artery, coronary artery, kidney and other important organs. Those with fatigue, fatigue, dizziness, memory loss, chest tightness, severe cases can induce cerebral vascular accidents and angina pectoris , Myocardial infarction, decreased renal function, etc.;

On the other hand, posture hypotension may cause the elderly to fall suddenly after getting up, while the elderly often accompanied by osteoporosis, and often cause fractures after falling.

Therefore, for the elderly, the pressure of lowering blood is stable, and excessive antihypertensive is a harm to important organs such as our hearts, brains, and kidneys.

{Is it a good thing to have hypertension but not uncomfortable? }

Many people have hypertension but there are no symptoms, no dizziness and headache. This may be due to the gradual tolerance of the body during the slow rise in blood pressure, or as the age increases with age, the body function is reduced, which is not sensitive to the increase in blood pressure.

Regardless of the asymptomatic, the damage to important organs such as blood vessels, hearts, kidneys, brains, and eyes is continuously existing. Without symptoms, it makes it difficult for us to pay attention to this potential and long -term damage, and even some patients will choose to ignore and not treat them.

{Precautions for Hypertension in Summer}

01

Salt is very important

High -salt diet is an important factor in high blood pressure of Chinese people. Salt is very necessary, and the amount of salt per day should not exceed 5g/day.

02

Monitor blood pressure

The easiest way is to measure at home with a blood pressure instrument. Select 3 days and evenings. After 5 minutes of rest, measure blood pressure twice, each time the interval is 1 minute, and the average value is taken. If the differences between the two arms are consistent> 10 mmHg, use a higher blood pressure arm.

Patients with blood pressure fluctuations in summer should be monitoring of blood pressure to provide reference and basis for adjusting the treatment plan.

03

Don't be greedy in summer

The air -conditioning room temperature should be avoided too low, and the temperature difference between indoor and outdoor is less than 8 ° C. Avoid too much cold drink and avoid cold bath.

Cold and cold alternate can easily lead to severe blood pressure fluctuations. Suddenly entering the cold indoors or over -consumption of cold drinks from the hot outdoor, which leads to rapid contraction of blood vessels, increased blood pressure violently, and prone to cerebral blood accidents such as stroke.

04

Adjust the medication carefully

If the blood pressure is discontinued due to the decrease in blood pressure in summer, it is likely that the blood pressure has increased again, causing the vascular damage to increase, and even cause adverse events such as stroke and angina pectoris.

Be careful to adjust the medication carefully under the guidance of a doctor to avoid repeated fluctuations in blood pressure.

05

Pay attention to hydration

Pay attention to hydrating, do not wait for the thirst before drinking water. Because the water evaporates and sweats in summer, the body fluid is reduced, and the blood is thick, and it can be corrected by hydration.

06

other

Patients with hypertension should avoid exercise at high temperatures in summer. In summer, pay attention to improving the quality of night sleep, and you can also choose to restore your physical strength through lunch break.
