Hypertension patients are the most dangerous in summer! Remembering these two medication standards can save lives at critical moments.

High temperature in summer can dilate blood vessels, although it can speed up the metabolism and detoxification of the body, but for patients with hypertension, too high temperature will increase blood flow, and at the same time, too much water will be lost in the human body, and blood will easily become more viscous, which will not only easily increase the chance of stroke, but also easily lead to blood vessel blockage. Therefore, patients with hypertension will have worse adaptability to high temperature changes in summer.

perspire heavily

Once the temperature starts to rise, it will lead to the rapid evaporation of water in skin pores and respiratory mucosa, resulting in insufficient water and unbalanced water and electrolyte levels. Therefore, sodium ions will also be lost, lowering blood pressure, allowing lipids to precipitate on the inner wall of blood vessels, and increasing the incidence of various diseases such as cerebral thrombosis, stroke and myocardial infarction.

Humid and sultry

The sultry low air pressure will make it difficult to breathe. When the amount of air inhaled by the lungs decreases, the oxygen transport capacity in the blood will also decrease, and a compensatory reaction will be formed in patients with hypertension, which will lead to the acceleration of breathing and heartbeat and the increase of adrenal hormones, which will lead to hypotension.

Accelerate metabolism

People belong to warm-blooded animals, and there is a regulation mechanism of heat dissipation in the body. However, the neuromodulation mechanism of hypertensive patients is poor. In the face of high temperature, the temperature in the body suddenly rises, but the abnormal blood pressure is caused by the abnormal regulatory function of the body, and the probability of suffering from other cardiovascular and cerebrovascular diseases is increased.

Greedy and calm

Hot weather makes people feel good about cold food, such as iced drinks, iced fruits and ice cream. Although this kind of food can solve the temporary sultry feeling, if it is eaten in large quantities, it will cause the gastrointestinal tract to be stimulated by cold, which will lead to vasoconstriction and gastrointestinal discomfort. At the same time, it will also cause the pores and muscles of the whole body to contract, causing arterial spasm, which is not conducive to the passage of blood flow and induce blood pressure reduction.

In addition, after sweating, many people like to take a cold bath, but in the process of alternating hot and cold, it will cause uneven pressure inside and outside the blood vessels, which will easily lead to an increase in blood pressure. In summer, besides taking a cold bath and eating iced food to cool down, setting the air conditioning temperature too low may also increase blood pressure. When entering and leaving the air-conditioned room, the rapidly changing temperature difference makes it difficult for the body to adapt, which will cause the blood vessels to contract rapidly, slow down the blood circulation speed and cause the blood pressure to drop.

Hypertensive patients are subject to so many restrictions in summer, so how to prevent the harm caused by high blood pressure is also something that hypertensive patients need to pay attention to.

Insist on monitoring blood pressure

Drink more water.

Excessive sweating and hot air in summer will cause water loss in the body. If you want to balance the water and sodium in the body, you need to adjust the water consumption according to the amount of urine and the color of urine.

Drink plenty of boiled water, or add 1g salt appropriately, so that your body can get sodium supplement. In addition, in addition to getting water from boiled water, eating fruits and vegetables properly can also get more water, as well as vitamins, trace elements and minerals. And improve the regulatory function of the body. But you can't drink a lot of water at one time, otherwise it will easily increase the burden on the kidneys, increase the concentration of blood vessels, and increase the possibility of vasodilation and rupture.

Cooling down and summer vacation

It's uncomfortable not to turn on the air conditioner at high temperature. Although the outdoor temperature cannot be controlled, the indoor temperature can be controlled. Generally, the air conditioning temperature should be set between 26 and 28. This temperature range is neither too cold nor too hot, which can avoid the decrease of blood pressure caused by abnormal vasoconstriction to some extent. In addition, there is a safer way to dissipate heat, and that is swimming. Swimming can not only stretch the muscles of the whole body, promote the benign circulation of blood, but also take away excess heat to achieve the effect of strengthening the body.

Adjust the dose according to blood pressure

If hypertensive patients want to spend the summer smoothly, they should learn to adjust the dosage according to their blood pressure, avoid symptoms such as insufficient blood oxygen, dizziness and headache, and increase the chances of suffering from myocardial infarction and angina pectoris. But you must adjust the dose under the guidance of a doctor, and don't increase the dose without permission.

Although the dosage of the drug cannot be changed by itself, and the medication method should be taken in strict accordance with the doctor's advice, the following two medication standards should be kept in mind when taking antihypertensive drugs:

Don't stop taking medicine easily.

Some hypertensive patients may drop their blood pressure in summer and stop taking medicine without consulting a doctor, but their blood pressure will rise again in a few days. Patients with hypertension should know that the blood pressure drop in summer is not due to the recovery of the body's function of regulating blood pressure, but because the blood vessels expand at high temperature, so the blood pressure can be stably maintained within the target range. If you stop taking drugs blindly and stimulate blood vessels repeatedly, it may induce cardiovascular and cerebrovascular adverse events.

Some patients may also have symptoms such as low blood pressure, black eyes, dizziness and discomfort. If such symptoms occur, you should lie flat immediately and seek medical attention as soon as possible. If the blood pressure continues to be lower than 1.20 mmHg within two weeks, it may be caused by excessive dosage of antihypertensive drugs, and the dosage should be adjusted as appropriate to avoid continuous hypotension, leading to ischemia of organs, muscles, nerves and tissues, and easily leading to stroke, coronary heart disease and other diseases due to insufficient blood perfusion.

Choose the right time to take medicine.

8- 1 1 in the morning is the early peak of blood pressure rise, and 3-5 pm is the late peak of blood pressure rise. However, antihypertensive drugs have different half-lives and different onset times. We should take antihypertensive drugs 30-60 minutes before the half-life fades, and coincide with the peak period of blood pressure rise, so as to optimize the bioavailability.

Although the hot weather in summer will bring patients with hypertension a sense of barely satisfaction, because in hot weather, arterial blood vessels will expand, leading to an increase in blood volume, and thus blood pressure will drop, but this is only an illusion. Therefore, only under the guidance of the doctor's advice, follow the reasonable medication principle and make personalized medication adjustment, so as to avoid abnormal blood pressure fluctuation to a greater extent.
