Winter, hypertensive patients how to safely cross the threshold

Autumn and winter temperature decreases, this is all dormant when, it is " an eventful year in patients with hypertension ". For patients with hypertension in winter than in summer, more difficult to control blood pressure in a normal range, especially in November each year to March of the following year, a year of cardiovascular and cerebrovascular diseases in the peak month of death. Therefore, the winter season is forthcoming, remind patients with hypertension disease, must vigilant attack.

A fact: in winter, blood pressure is difficult to control

In patients with hypertension and cardiovascular physicians have this feeling, when frost comes, antihypertensive drugs seem to be false, so a drug pressure adjusting well, now two piece of control, is the original feeling and experience, there is no evidence, but in recent years, the United States of America heart learn to researchers in a study, let us understand thoroughly the winter in patients with hypertension what. Study on more than 440000 patients with hypertension were a period of 5 years of follow-up, patients throughout the United States in 15 city, north to the cold Alaska, South to the warmth of the Puerto Rico. The researchers found that, regardless of geographic, racial and gender, blood pressure control in winter than in summer 8% normal persons.

Reason: two, thermal expansion and contraction, vascular contraction

Hypertension is a closely related diseases and meteorological changes. Based on the influence of genetic factors, patients with sympathetic reactivity was higher than those in controls, specific performance: the usual nervous, excited, can not adapt to the change of environment. The arrival of winter, the cold stimulation can result in abnormal sympathetic activation, resulting in cardiac contractile force enhancement, peripheral vasoconstriction, leading to systolic and diastolic blood pressure rise. In addition, the vascular itself, also comply with the " thermal " principle, hot summer and cold winter vasodilation, vasoconstriction. In addition, because winter people gain weight, changes in eating habits and exercise too little may also lead to increased blood pressure, at the same time, the winter diet may eat more salt, but also to urge the elevated blood pressure is one of the reasons.

Three, the consequences: myocardial infarction, stroke concentrated high

In the case of climate change, the fluctuation of blood pressure increases, the main risk is the leading cause of acute disease, especially cerebral hemorrhage, cerebral infarction and myocardial infarction incidence. For example, like a rubber hose, arrived when the weather is cold, rubber will become brittle, if the water pressure increases, it is easy to open, our blood vessels is also so. Every winter, especially when temperatures drop, the hospital emergency room packed with stroke, myocardial infarction patients also increased significantly, this phenomenon is more obvious in our northern region. Especially in the elderly, vascular itself elastic itself than the young people should have the difference, therefore, cerebral hemorrhage, myocardial infarction and other accidents probability is higher.

Four, procedures: a warm, appropriate move, eat less salt

Nevertheless, hypertension patients also need not excessive worry, like fighting just as winter will increase heart burden. Because the mental strain, also on the hypertensive patients with adverse. In fact, as long as the attention to small details of life, the same can safely for the winter. Details are as follows:

1, pay attention to warm, avoid cold stimulation, especially cold spell, when temperatures drop, attention should be paid to add clothes, to prevent a cold. Hypertensive patients should pay close attention to climate change, and watching the local weather forecast, the unstable heating conversion seasonal weather, should know in advance, in advance of preventive measures. Pay particular attention to the first cold air cooling weather process, the strong wind and a temperature should be as little as possible, or do not go out, if you must go out to work, should take effective measures of protection, such as extra clothes, hat, scarf, wearing masks and so on.

2, in the diet should eat some heat production and nutrient rich foods, such as meat, chicken, fish, dairy and soybean products, eat greasy food, taboo tobacco. Dietary structure should be of low salt, low fat, low cholesterol, best can use vegetable oil, as well as many fresh vegetable & fruit. An hour before bedtime drink a glass of water ( if at night, can be properly in advance, according to their specific implementation ), get up early in the morning to drink a cup of blood, it has good dilution effect.

3, exercise, improve the ability to cold. Do everything in one's power can participate in some sports activities, such as walking outdoors, shadowboxing, do qigong. In the winter, avoid going out early in the morning for running exercise activities, outdoor activities should be selected after nine thirty in the morning to afternoon 4 when before period of fine weather.

4, appropriate control of emotional, beware excessive fatigue. Extreme anger or stress can induce myocardial infarction and stroke, therefore, hypertensive patients to remain optimistic and cheerful mood, rage, depression, avoid rapture sadness, fear and fright.

5, adherence to medication, and appropriate adjustments, keep blood pressure stable. Avoid arbitrarily stopping medicine, general situation of hypertensive patients in winter should be appropriate to increase the amount of blood pressure lowering drugs.
