What natural factors and how they affect our state of health and who more, and who is less inclined to certain weather changes.
Among the most significant meteorological factors can be distinguished atmospheric pressure, air temperature, humidity, wind speed. The human body is influenced by Heliophysical factors - magnetic fields, as well as flares in the sun.
Atmospheric pressure and well-being
Depending on the characteristics of blood pressure, the effect is different Atmospheric pressure Per person
When the pressure decreases, the oxygen content in the atmosphere decreases. As a result, blood pressure may decrease, which means that the speed of blood flow decreases, breathing is difficult, difficulty in the head appears, work of the cardiovascular system is disturbed.
Low atmospheric pressure has a particularly negative effect on hypotonics. They have fluid retention in the body, with moderate physical activity, there is a tendency to accelerated heart contractions and, as a consequence, accelerated breathing. These symptoms indicate hypoxia.
In hypertonia, in such a state of health can improve. On the contrary, they, on the contrary, carry excessive atmospheric pressure worse: they can lead to an exacerbation of arterial hypertension.
Air temperature and well-being
High Air temperature In combination with high humidity (90-100%) and low atmospheric pressure are difficult to tolerate hypotonic, people with pathology of veins suffering from chronic inflammatory diseases - gout, rheumatoid polyarthritis, chronic bronchitis and chronic inflammatory diseases of the intestines and pancreas.
In addition, in such weather the saturation of air with oxygen decreases, therefore it is generally difficult to tolerate the elderly.
The high temperature is much easier to carry at normal or even slightly elevated atmospheric pressure, which is accompanied by low humidity of air. However, such weather always leads to some blood condensation and the risk of not only venous blood clots in people with heart failure and varicose veins, but also arterial thrombi.
Therefore, in heat with high atmospheric pressure, there is a high risk of stroke or heart attack. Doctors advise in case of anomalous heat as much as possible in the room with an air conditioner or fan, to avoid the sun, unnecessary physical activity. It is recommended to adhere to a low-calorie diet, to consume more fluids.
" When abnormal heat, when the external temperature becomes higher than the body temperature, the human body undergoes a serious test, - says Anton Rodionov, assistant professor of faculty therapy department №1 of the medical faculty of the First MGMU them. IM Sechenov. - In hot weather, a person sweats intensely, which inevitably accompanies the loss of fluid and electrolytes. Excessive fluid intake leads to thickening of the blood and increased risk of thrombosis, and electrolyte disturbances can provoke cardiac arrhythmias. Consequently, in the heat it is necessary to adequately fill the lost liquid; It is desirable to drink not a simple, and mineral water, which already contains more or less balanced set of electrolytes. In addition, patients with an increased risk of thrombotic complications should be particularly careful with the doctor-recommended doctor: patients with coronary heart disease should receive aspirin, and patients with flashing arrhythmia - anticoagulants. "
Humidity and well-being
Excessive dryness of air may be the cause of the spread of acute respiratory viral infections. If the mucous nasopharynx is atrophic, then it becomes more susceptible to respiratory viruses.
" To avoid excessive dryness in the nasopharynx, it is recommended to rinse with a solution of slightly saline or non-carbonated mineral water, to protect the mucous membrane you can periodically resorb the candles on the basis of burned sugar - Advises Tatyana Alikhashkina, a therapist, deputy head of the polyclinic №1 of the NMHC named after Pirogov. - As agents of nonspecific antiviral action, preparations that have a minimum of side effects and the absence of age restrictions will be suitable. For strengthening of immunity - vitamin C. And of course, do not forget about summer fruits and berries rich in all necessary vitamins. "
Solar activity and health
The sun determines the daily cyclicity of the body. In the absence of sunlight and low temperature, we experience increased drowsiness, fatigue, depression, apathy, reduced performance and attention. Sunlight provides active metabolism, immunity and regulates the growth of tissues and bones, since activates vitamin D, without which it is impossible to absorb calcium.
However, the radiation of the sun - is also penetrating radiation with different ability not only to activate, but also harm our body. Excessive sun exposure can lead to sunburn or burns of the skin, the appearance of allergic dermatitis.
Irina Anatolievna Zalem, MD, Ph.D., Head of the Consultative Department of the Polyclinic of the National Medical and Surgical Center named after. MM Pirogova Roszdrava: "Allergy to the sun - a fairly common phenomenon, which can run both on the coast and at the dacha outside Moscow. The first symptoms of this allergy occur within 1-2 hours of continuous exposure to sunlight and resemble sunburn - man blushes, skin There are rashes, blisters and edema.If such a reaction, you will have to hide from the sun or wear long-sleeved clothes, a hat and use sun-protection with the maximum degree of protection.If long stay in the sun can not be avoided, my to take antihistamine for prevention - means the second generation allergy eliminate a day, and less modern drugs - a few hours. "
Much less often people remember that excessive solar radiation can damage our internal environment, activate inflammation and lead to premature aging.
" Excessive ultraviolet radiation can damage cell membranes and even the nucleus of any cell. Essential phospholipids, which serve as a building material and provide the work of all cells of the body, become trapped both for ionizing radiation that penetrates the body and for the peroxides that are formed as a result of irradiation, - Cautions Olena Vovk, associate professor of the Department of Therapy, Clinical Pharmacology and ambulance MDMUU. - In order to maintain active protection against radiation and to restore cell membranes, our body needs active intake of vitamins-antioxidants: С, А, Е and the continuous replacement of destroyed phospholipids. For this we need to have a supply of fatty acids - the main component of phospholipids. We can create such a reserve only by way of their receipt in the body with food or in the form of drugs. "
We can not change weather conditions, but in our capacity to reduce the health risks associated with environmental influences. For people with diseases of internal organs, it is important not only to learn to detect, but also to be able to defend themselves against harmful effects in a qualified manner.
If on the background of a change in the weather you have an exacerbation of a chronic disease or a sharp deterioration of well-being - consult with your doctor and start treatment in a timely manner.
