Causes of flu

As is known, the flu and colds occur mainly in one period of the year – winter. This fact usually leads people to believe that these infectious diseases are caused by the cold. But flu epidemics there in early spring and summer, and early fall. Therefore, the reason must be sought not only in him. Of course, cold is triggering factor as the cooling of the body, especially the limbs, attacking the lining of the upper and lower respiratory tract, creating the necessary conditions for the development of colds.

The main cause of flu is, in general, reduced immunity due to unsustainable lifestyle. There is a mandatory body contamination with toxic products due to overfeeding or feeding unsuitable products, smoking, consumption of alcohol, pollution, poor living conditions, contaminated professional environment, promiscuous drug delivery and more. immobilization, physical and mental exhaustion, stress.

During periods of influenza and colds, namely the beginning of the autumn-winter, early spring and summer, summer, nature, profound changes associated with the onset of solar activity. Land pour huge amounts of solar and cosmic energy needed to perform the process in nature that will permanently disrupt the human body if it is dirty.

We will explain why is it the example of the season in which colds are the most common, namely the autumn-winter period. Under the influence of the cold situated waste substances in the blood starts to pass into the tissue in the form of mucus. If you do not take preventive measures, this mucus will gradually thicken the tissues and interfere with the normal functioning of cells throughout the body. Will experience various diseases, including influenza, which aims to separate the body from accumulated mucus in the form of phlegm cough, fever or high temperature. In this sense they are timely cleansing reaction designed to put or burn toxins.

Why fight the flu and colds should be quick, timely, urgent and energetic? Because they did not have innocent as considered and may lead behind severe complications: respiratory system – pharyngitis, bronchitis, pneumonia, bronchopneumonia, bronchial asthma, laringotraheobronhit; cardiovascular and nervous system – encephalitis, myocarditis urinary tract – kidney disease; of the musculoskeletal system – rheumatism and other joint inflammation, etc.
