The change of seasons is reflected not only our mood, but also our health. When the heat is retained for a long time, they can become very dangerous and take thousands of victims. The heat is most detrimental to our heart.
Summer heat is a challenge even for perfectly healthy people, but those with cardiovascular diseases and blood circulation problems should be especially careful. In the risk group are suffering from various chronic diseases - arterial hypertension, coronary artery disease, those who have had a stroke, diabetes mellitus, chronic lung disease.
In the heat it produces a strong dilation of blood vessels and a large heat. This is a normal compensatory mechanism which leads to a more intensive circulation in the skin and thus cooling the body by sweat. This is often the cause of significant loss of fluid, which can lead to dehydration of the body. Sweating increased blood viscosity, which further strain on the heart, since it requires more power and strength to pump blood, so people with heart failure feel tired, tired, no strength to perform everyday activities. Come to thicken the blood and tendency of clots in the vessels, ie - increase in heart attacks and strokes. But when they pass a certain threshold may occur opposite - a paradoxical reaction to constriction of blood vessels. And one and the other are equally dangerous for these patients. Therefore, stenocardiac crises should promptly seek medical advice.
Typical is the emergence of rhythm disorders - most commonly occurs in the heat tachycardia - fast heart rhythm, often reaching up to 150-160 beats per minute at rest. Dehydration occurred in turn leads to loss of valuable ions - sodium, potassium, chlorine, magnesium. If not properly compensate these losses prejudice metabolic balance. If sodium is readily recovered by salting of food, the potassium is contained in the fruit and can be taken regularly to them (especially apricots), the magnesium is often in short supply due to its rapid excretion from the body, especially in patients receiving diuretics regularly for lowering blood pressure. Therefore rhythm disorders and painful muscle cramps are common in people with high blood pressure combination therapy with a diuretic. Therefore, one of the most vulnerable groups in the warm days are hypertensive. In these heat often provoke drastic changes in blood pressure - as well as lowering and raising. Often these patients, contrary to expectations, are reacted with an even greater increase in the values of blood.
