There are liquid lost in the heat , which is extremely dangerous not only because it is broken water balance, which affects the normal functioning of many organs, but also because blood clots can occur, leading to thrombosis. Therefore, the loss, of course, must be replenished. Yes thirst and she tells it. It is best to use potable water, fruit and vegetable juices, mineral water and tea. Liquids that contain caffeine, alcohol, large amounts of sugar, will do more harm than good - they lead to dehydration. You need to drink a little during the day, without waiting for the state, when thirst becomes unbearable - then we can unwittingly exceed the norm, and for patients with cardiovascular disease increased water load too dangerous.
For me it is also very difficult times. Doctors say that the most serious blow when exposed to extreme heat the human cardiovascular system. At higher ambient temperature starts to work harder the heart, the pulse quickens, blood vessels dilate, blood pressure often falls. In the heat of the body loses a lot of fluid, and with it - mineral salts. This potassium and magnesium, the lack of which in the heat is particularly acute, is needed for the heart and maintaining cardiac rhythm. Another consequence of dehydration is blood clots. In tandem with low blood pressure, it increases the risk of blood clots.
The first reaction for the heat is actively sweating. Thus there is thermoregulation. In this respect, we were lucky - animals sweat glands are underdeveloped and their thermoregulation is mainly through the mouth. The intensity of the cooling of the body in the heat depends on the amount and the rate of evaporation of sweat from the body surface. In addition, through the sebaceous glands are also allocated fatty substances, which also contributes to more efficient perspiration. Dehydration, water scarcity is not the main problem. The main thing is that together with then the body loses salts and minerals. Their deficiency directly affects the cardiovascular system and the functionality of the brain.
I think the heat may have different effects on the body. In addition, one of the most terrible thing is really dehydrated. And very often we just do not understand how this can be dangerous as a result. Dehydration in the heat depends on the level of human activity. In intensive work or sports vlagopoteri may constitute 5-6 liters. When walking in the sun sweating doubled, while running - in 4-6 times. Seriously affect the well-being not only high temperature, but also humidity. The temperature of 40 ° C and 30% relative humidity perceived by the body as well as the temperature of 30 ° C and 80% humidity.
The heat not only affects the human physiology but also on his psyche. The most critical and provocative aggression on the temperature of 27-30 degrees. If the temperature is less than 27 ° C, then the person with it copes; if the temperature is above 30 ° C and approaching 40 ° C, until it is no aggression. The body in this hell spends a lot of effort to maintain homeostasis (constancy of internal environment) and human switched "power saving mode". How to protect yourself from the heat and keep not only health, but also the performance? Most importantly - avoid a long stay in the sun. If you can take refuge in the shade - take cover.
In the heat you need to wear the right clothes. Ideally, it was cut free, and covered the whole body (remember the Bedouin robes). Shorts and T-shirt - it is certainly good, but this bow is not suitable for a long stay in the sun. Large open areas of the body can provoke not only the heat, but heat stroke, you can also get a sunburn. Especially in hot weather is necessary to protect the head. Panama hats and caps bright colors are just right. Ideal as - or turban scarves, like a Bedouin. Of course, you need to drink a lot. And not necessarily water. Good save from dehydration unsweetened juices, broth hips, linden or thyme, water with lemon, fruit.
To be honest, I'm not surprised that this question we have to discuss, even here. For weather forecasts, this summer will be extremely hot. Scorching sun not only ensures chocolate tan, but also provide employment to doctors of "first aid" and cardiology and intensive care. Because the unbearable heat in the settlements and high humidity in parts of the resort impairs health of people suffering from diseases of the cardiovascular system. That is why at the height of summer, when the air temperature reaches 40 ° C or higher, you should take a few minutes of valuable recommendations on how to protect the heart from a possible attack.
Like all living things, man is sensitive to weather changes. In contrast to our younger brothers (dogs, horses, mice, snakes, birds), we can not feel the approaching natural disaster - the tsunami, tornadoes, floods. However, the human body reacts to the weather surprises, in particular - the heat. Medical experts say that the modern man, who grew up and lives in heated and cooled rooms with artificial microclimate, less adapted to the changes of weather (a sharp cooling or warming) in comparison with their ancestors, more resistant to changes in temperature and humidity, atmospheric pressure.
With increasing levels of heat are observed numerous cases of hypertension and hypotension, angina, myocardial infarction and stroke. Many people in the heat is not able to work is not something that - even leave their home due to blood pressure surges, painful headaches, weakness, lack of oxygen. The fact that the heat dilates the blood vessels, thereby causing the heart to work harder for an adequate circulation. Accordingly, in this case the heart is experiencing additional load reflected tachycardia and ischemic heart disease. Sudden changes in temperature or humidity may instead provoke vasoconstriction, which often leads to the formation of a blood clot and is fraught with heart attack.
I think that the heat can be dangerous for almost any people. People already suffering from cardiovascular diseases and have a predisposition to these pathologies, it is important to observe in the sultry season simple prevention measures, so as not to spend your vacation in a hospital bed. Since the serious illnesses of the heart and blood vessels characters in most cases for the elderly, cardiologists called hypertension and its complications disappointing "vegetable garden disease." The youth of today is committed to comfortable conditions of employment, preferring intellectual work, whereas the older generation retired or during leisure activities can be found on the land.
