Among the most important meteorological factors can distinguish atmospheric pressure, air temperature, humidity, wind speed.On the human body is influenced by factors heliophysical - magnetic fields and solar flares.
Depending on the characteristics of blood pressure varies exposure atmospheric pressure per person.
oxygen content in the atmosphere is reduced under reduced pressure.As a result, may decrease blood pressure, and therefore decreases blood flow and speed, difficulty breathing, there is a heaviness in the head, the work violated the cardiovascular system.
Low atmospheric pressure is particularly adversely affects the hypotensive.They occur fluid retention in the body, with moderate physical exercise are prone to more frequent heart rate and, as a consequence, rapid breathing.These symptoms indicate hypoxia.
in hypertensive patients is in this weather the state of health can be improved.They, on the contrary, worse tolerate high atmospheric pressure at which it can exacerbate hypertension.
High air temperature combined with high humidity (90-100%) and low air pressure hard to tolerate gipotoniki, people with vein disorders, chronic inflammatory diseases - gout, rheumatoid arthritis, chronicbronchitis and chronic inflammatory diseases of the intestine and pancreas.
In addition, in this weather decreases the saturation of oxygen in the air, so it is generally difficult to tolerate the elderly.
Heat is much easier to bear under normal or even slightly elevated atmospheric pressure, which is accompanied by low humidity.However, the weather always leads to some thickening of the blood and the risk of the emergence of education not only of venous blood clots in people with heart failure and varicose veins and arterial blood clots.
Therefore, in the heat with increased atmospheric pressure is high risk of stroke or heart attack.Doctors advise if abnormal heat as much as possible to be in a room with air conditioning or a fan, to avoid the sun, extra exercise.It is recommended to observe low-calorie diet, drink plenty of fluids.
« When heat waves, when the outside temperature is above body temperature, the human body is exposed to a serious test , - says Anton Rodionov, Associate Professor of Faculty Therapy №1 Medical Faculty First MGMU them.Sechenov.- In hot weather, a person sweats heavily, which is inevitably accompanied by the loss of fluids and electrolytes.Excess fluid excretion leads to thickening of the blood and increase the risk of thrombosis, and electrolyte disturbances can trigger cardiac arrhythmias.Therefore, in the heat necessary to adequately compensate for the lost fluid;it is desirable to drink not simple, and mineral water, which already has a more or less balanced mix of electrolytes.In addition, patients with an increased risk of thrombotic events should be especially careful to follow the doctor recommended drug therapy: patients with coronary heart disease should take aspirin and patients with atrial fibrillation - anticoagulants ».
Excessive dryness of the air may be the cause of the spread of SARS.If atrophic nasal mucosa, it becomes more susceptible to respiratory viruses.
« To avoid increased dryness in the nasopharynx, it is recommended to do the washing solution, salted or non-carbonated mineral water, to protect the mucous membrane of the throat can occasionally dissolve candy based caramel , - advised Tatyana Alihashkina, physician, deputy director of the clinic number 1 NMHTS Pirogov.- as a means of non-specific antiviral drugs action suit, with a minimum of side effects and the lack of age restrictions .In order to strengthen immunity - vitamin C. And of course, do not forget the summer fruits and berries, rich in all the necessary vitamins. "
sun determines the daily cycles the body.With a lack of sunlight and low temperatures we experience increased sleepiness, fatigue, depression, apathy, decreased performance and attention.Sunlight provides an active metabolism, the immune system and regulates the growth of bones and tissues, because activates vitamin D, which is essential for calcium absorption.
However, radiation from the sun - it is also penetrating radiation with varying ability to not only enable, but also harm our body.Excessive sun exposure can lead to heatstroke or burns the skin, appearance of atopic dermatitis.
Irina Salem, MD, physician, head of the advisory department clinics of the National Medical and Surgical Center.NNPirogov Medical University: «Allergy to the sun - a very common phenomenon which can be faced with both at the seaside and in the dacha outside Moscow.The first symptoms of this allergy appear after 1-2 hours of continuous exposure to sunlight and resemble a sunburn - man blush, appear on the skin rashes, blisters and swelling.If such a reaction from the sun have to hide or wear long sleeves, wide-brimmed hat and use sunscreen with maximum protection.If prolonged sun exposure can not be avoided, it can be taken for the prevention of an antihistamine - the second generation means eliminate allergy symptoms for a day and less than modern drugs - for a few hours. "
Much less people remember that excessive exposure to the sun can damage our internal environment, activate inflammation and lead to premature aging.
« Excessive UV radiation can damage cell membranes and even the nucleus of every cell.Essential phospholipids, which serve as building blocks and ensure the operation of all cells of the body become traps for penetrating into the body ionizing radiation, and for peroxides, which are produced as a result of exposure , - warns Elena Vovk, associate professor therapy departments, Clinical Pharmacology and MedicalMSMSU assistance.- To maintain active protection against radiation and the recovery of cell membranes in our body needs the active receipt of antioxidant vitamins C, A, E and continuous replacement of destroyed phospholipids.To do this we need to have a supply of fatty acids - the main component of the phospholipids.We can create such a reserve is only through the intake of food or in medicine. "
We can not change the weather, but we can reduce the health risks associated with exposure to the external environment.People with diseases of the internal organs is not only important to learn to identify, but also to be able to competently defend themselves from the harmful effects.
If on a background of changes in the weather's going exacerbation of a chronic disease or sharply deteriorating health - consult your doctor and start treatment promptly.
