Hot weather and high blood pressure.

In recent days, high temperature weather has appeared in many areas, from Inner Mongolia to Shandong, Anhui and Zhejiang, the temperature is above 35, and some areas even reach about 40. Some netizens ridiculed that this hot weather turned Henan into "Conan" and Jinan into "Qinnan".

From a health point of view, in such hot weather, there is a risk of cardiovascular disease, and friends with cardiovascular disease problems should pay more attention. Previous survey data show that the risk of cardiovascular disease will increase 1 every time the temperature rises above 30. Therefore, summer is by no means a low incidence period of cardiovascular diseases. For friends with related risks, we must also pay attention to life adjustment and disease control, try our best to protect heart health and reduce the cardiovascular and cerebrovascular risks caused by rising temperatures.

As many friends know, the cold temperature in winter will promote vasoconstriction and reduce the body's immunity, which is the high incidence of cardiovascular diseases. Why is it hot in summer, or will it increase the risk of cardiovascular disease? There are many reasons for this.

First of all, in hot weather, various organs of the body will bear greater pressure, and the load on the heart will further increase. If you have cardiovascular stenosis or three high chronic diseases, you are a high-risk group of cardiovascular diseases. The long-term increase of heart load is easy to induce cardiovascular and cerebrovascular diseases, which deserves special attention.

Hot weather will affect many people's appetite. For those elderly friends who are already at risk of cardiovascular disease, they can't keep regular and healthy eating habits, and their bodies can't get adequate nutrition supply. It may also lead to dysfunction of blood vessels, heart and other aspects, which in turn brings the risk of cardiovascular diseases.

You will sweat a lot in summer. If you sweat a lot, but don't replenish water in time, your body is in a state of water shortage. The first thing that will be affected is the decrease of blood volume, the increase of blood viscosity, the slow blood flow, the aggregation of coagulation substances in blood, and the risk of thrombosis will further increase.

In hot weather, people's mood is also prone to changes such as irritability and irritability, and the influence of bad emotions also affects the regulation function of autonomic nerves, bringing about various problems such as accelerated heart rate, vasoconstriction and elevated blood pressure. The cardiovascular health risks caused by emotional influence are easily overlooked, which is actually very common.

There are also some elderly hypertensive patients with severe vascular sclerosis. Taking the original dose of antihypertensive drugs in summer will lead to the risk of hypotension. Low blood pressure will not only cause fatigue and dizziness, but also accelerate the heartbeat, bringing the risk of sudden cardiovascular and cerebrovascular events.

The above five aspects are all important reasons for increasing the risk of sudden cardiovascular diseases in hot summer, especially for elderly friends whose physical function declines with age, and more attention should be paid to the prevention and treatment of cardiovascular and cerebrovascular diseases in hot weather. What shall we do? Here are five suggestions.

For hypertension control in summer, there are two situations that will bring risks. Some patients with hypertension, in the summer, their blood pressure is a little low after taking the medicine, so they stop taking the medicine quickly and wait until the weather gets cold. The second situation is that after taking the original antihypertensive drug, the blood pressure has dropped to low blood pressure, but still insist on taking the drug.

In fact, in the final analysis, these two situations are caused by not paying attention to blood pressure monitoring. The purpose of controlling blood pressure is to keep blood pressure in a stable range. It is an important means to monitor whether blood pressure is well controlled by measuring blood pressure regularly and knowing our own blood pressure control. In the summer when the temperature alternates between hot and cold, patients with hypertension should pay more attention to monitoring their blood pressure and know their own blood pressure control.

If you take the original antihypertensive drugs, it is not a good choice to insist on medication except for low blood pressure, which will bring cardiovascular risks; However, it is not a good choice to stop taking drugs completely. Stopping the drug completely may make the originally controlled blood pressure out of control and soar again, and the risk is also great. A better way is to adjust the medication scheme reasonably according to the actual situation, which can not only reduce the risk of hypotension, but also ensure the stable control of blood pressure. This is indeed a good way to control the risk of cardiovascular disease by rational drug use.

In addition to medication, it is also important to do a good job in life. In terms of diet, you should neither overeat nor eat too little because of the hot weather. It is necessary to reasonably match the diet and have a light diet. Eat more seasonal fruits and vegetables in summer, such as eggplant, beans, loofah, pepper, bitter gourd, wax gourd, amaranth and fruits such as watermelon, peach, plum, apricot, mango and mangosteen, which are all good nutritional supplements.

In daily life, the days are long and the nights are short in summer, but we should also pay attention to maintaining a healthy and good sleep. For most elderly friends, going to bed early and getting up early is more beneficial to cardiovascular health than going to bed late and getting up late. Although the weather is hot, you still have to sleep for 7 to 8 hours every day. You should pay attention not to be too anxious when you get up in the morning. After waking up, you should lie in bed for a while, and then get up slowly after you are fully awake, which can reduce the cardiovascular risk in the morning and pay special attention.

A good mood is a good medicine for health. No matter what season, no matter how hot the weather is, you should keep yourself in a peaceful mood, don't worry about unnecessary things, and don't be upset because of the hot weather. If you are in a rage or anxious mood, sudden cardiovascular and cerebrovascular events will really outweigh the benefits.

"Calm and naturally cool" can not only reduce the risk of cardiovascular and cerebrovascular diseases, but also make us feel naturally cool from the inside out in the heat.

Some friends like exercise, which is a good way to adjust their lives, prevent cardiovascular diseases and improve their metabolic function. However, in hot summer weather, we should pay attention to the ways and methods of exercise.

First of all, don't exercise in the hottest time. You should choose a time when the temperature is low, such as early morning or evening, or go to a gym with the right temperature, which is a good choice. Secondly, when the weather is particularly hot, we should adjust the intensity of exercise according to our own situation. If it is not suitable for high-intensity exercise, the amount of exercise can be appropriately reduced in hot days, and a small amount of exercise can be stopped in particularly hot days. The third thing to note is that you should replenish water to your body in time after sweating and exercising in summer.

It's hot in summer. I hope it's cool, but for elderly friends who are at risk of cardiovascular disease, we should pay special attention not to overeat. Of course, you can use air conditioning to make your body feel more comfortable, but you should also be careful not to set the air conditioning temperature too low, which will lead to excessive temperature difference between indoor and outdoor. Sudden cold and hot stimulation is vasodilation, which may increase cardiovascular risk.

On the other hand, we should pay attention to the fact that some friends like to take a bath. For patients with cardiovascular diseases, try not to use pure cold water. Cold water can also stimulate vasoconstriction, which will bring certain heart risks. Cases of cardiovascular diseases caused by overeating and rushing to take a bath are also common. Taking a bath with warm water at a suitable temperature will not only reduce the risk, but also bring a cool feeling after taking a bath, which cannot be replaced by taking a cold bath. Never, just to "cool off temporarily".

The above aspects are all important aspects for the elderly to prevent the risk of cardiovascular diseases and reduce the occurrence of cardiovascular risk events in high temperature weather.
