Patients with high blood pressure are most at risk in summer! Keeping these two medication standards in mind can save lives at critical moments
High temperatures in summer will cause blood vessels to dilate. Although it can speed up the body's metabolism and detoxification, for patients with hypertension, too high temperatures will increase blood flow, and at the same time, the blood will lose too much water due to the body's water loss. It easily becomes more viscous, which not only increases the risk of stroke, but also easily causes blood vessel blockage. Therefore, patients with hypertension will have worse blood vessel adaptability when coping with high temperature changes in summer.
Profuse sweating
Once the temperature begins to rise, the water in the skin pores and respiratory mucous membranes will begin to evaporate rapidly, causing the body to be dehydrated and causing an imbalance in water and electrolyte levels, so sodium Ions will also be lost, causing blood pressure to drop, allowing lipids to precipitate on the inner walls of blood vessels, increasing the incidence of cerebral thrombosis, stroke, myocardial infarction and other diseases.
Humid and muggy
Sultry and low air pressure will make it difficult to breathe. When the amount of air inhaled by the lungs decreases, the oxygen transport capacity of the blood will also decrease, resulting in high blood pressure. A compensatory response will form in the patient's body, resulting in accelerated breathing and heartbeat, leading to an increase in adrenal hormones, resulting in hypotension.
Metabolism is accelerated
Humans are endothermic animals, and the body has a regulatory mechanism to dissipate heat. However, patients with high blood pressure have poor neuroregulatory mechanisms. When faced with high temperatures, the body temperature drops sharply. However, due to the abnormality of the body's regulatory function, it can lead to abnormal blood pressure and increase the chance of suffering from other cardiovascular and cerebrovascular diseases.
Greed for coldness
In hot weather, people have a fondness for cold food, such as: iced drinks, iced fruits, ice cream, etc., although such foods can relieve the temporary feeling of stuffiness. , but if you eat a lot, the cold stimulation of the intestines and stomach will cause vasoconstriction, causing gastrointestinal discomfort. It will also shrink the pores and muscles of the whole body, causing arterial spasm, which is not conducive to blood flow and induces a decrease in blood pressure.
In addition, many people like to take cold showers after sweating. However, the alternating process of hot and cold will cause uneven pressure inside and outside the blood vessels, which can easily lead to an increase in blood pressure. In summer, in addition to taking cold showers and eating iced food to cool down, setting the temperature of the air conditioner too low may also increase blood pressure. When entering and exiting the air-conditioned room, the rapidly changing temperature difference makes it difficult for the body to adapt, which will cause rapid blood vessels. Contraction, reducing blood circulation speed and causing blood pressure to drop.
Patients with high blood pressure are subject to so many restrictions in summer, so how to prevent the harm caused to the body by increased blood pressure is something that patients with high blood pressure need to pay attention to.
Keep monitoring your blood pressure
Drink more water
Heavy sweating and hot air in summer will cause water loss in the body. If you want To balance the body's water and sodium, you need to adjust the amount of water you drink according to the amount and color of your urine.
Just drink more boiled water, or add 1g of salt appropriately to supplement the body's sodium. In addition, in addition to getting water from boiled water, you can also get more water by eating fruits and vegetables appropriately. You can also get vitamins, trace elements, minerals, etc. to improve the body's regulatory function. However, replenishing water cannot be taken in large amounts at one time, otherwise it will easily increase the burden on the kidneys, increase blood vessel concentration, and increase the possibility of blood vessel dilation and rupture.
Cool down and escape the heat
It is very uncomfortable not to turn on the air conditioner in high temperatures. Although the outside temperature cannot be controlled, the indoor temperature can. The air conditioner temperature is generally set between 26-28. This temperature range is neither too cold nor too hot, which can avoid abnormal vasoconstriction to a certain extent and cause lowering of blood pressure. In addition, another safer way to dissipate heat is swimming. Swimming can not only stretch the muscles of the whole body and promote good blood circulation, but also take away excess heat and achieve the effect of strengthening the body.
Adjust the dosage of medicine according to blood pressure
If patients with high blood pressure want to spend the summer smoothly, they must learn to adjust the dosage of medicine according to their blood pressure. , to avoid symptoms such as hypoxemia, dizziness, headaches, etc., and increase the chance of suffering from myocardial infarction and angina pectoris. However, the dosage needs to be adjusted under the guidance of a doctor, and do not increase the dosage without permission.
Although the dosage of the medicine cannot be changed on your own, the medication must be taken in strict accordance with the doctor's instructions. When taking antihypertensive drugs, the following two medication standards should be kept in mind:
Do not stop taking the medicine easily< /p>
Some hypertensive patients may experience a drop in blood pressure in summer and stop taking medication without consulting a doctor. However, their blood pressure will rise again in a few days. Patients with hypertension should understand that the blood pressure decreases in summer is not because the body's function of regulating blood pressure is restored, but because the blood vessels are dilated under high temperatures, so the blood pressure can be maintained stably within the target range. If the medication is stopped blindly, repeated stimulation will occur. blood vessels, may induce the incidence of adverse events of cardiovascular and cerebrovascular diseases.
Some patients may also experience hypotension, dark vision, dizziness and discomfort. If such symptoms occur, they should lie down immediately and seek medical attention as soon as possible. If the blood pressure continues to be lower than 120mmHg within 2 weeks, it may be due to excessive antihypertensive dose. The dose needs to be adjusted as appropriate to avoid sustained hypotension, which may lead to ischemia of internal organs, muscles, nerves, and tissues, which may cause It is easy to suffer from insufficient blood perfusion and induce stroke, coronary heart disease and other diseases.
Choose the correct time to take medicine
8-11 am is the morning peak of blood pressure rise, and 3-5 pm is the evening peak of blood pressure rise. However, the half-lives of antihypertensive drugs are different. The onset of effect is also different. Antihypertensive drugs should be taken 30-60 minutes before the half-life disappears, and coincide with the peak period of blood pressure rise, so that the bioavailability can be optimized.
Although the hot weather in summer will bring a barely satisfactory feeling to patients with high blood pressure, because in hot weather, arteries and blood vessels will expand, resulting in an increase in blood volume. , so the blood pressure is reduced, but this is just an illusion. Therefore, personalized medication regimen adjustments must be made under the guidance of the doctor's advice, and reasonable medication principles must be followed to avoid abnormal blood pressure fluctuations to a greater extent.
