How to protect yourself from ticks
Since there are more and more cases of tick-borne encephalitis every year, in summer it is imperative to remember the rules of behavior in the forest.
For starters, don’t panic! The carriers of this virus in the middle lane are only a few percent of ticks.
Also, to protect yourself, you can get vaccinated. The first – in the fall, and the second – in the early spring.
Before going to the forest or the countryside, treat clothes with repellents. They can not be applied to the skin, but if the tick clings to such a tissue, it will die within a few minutes. Continue reading
What is iron deficiency anemia?
Infants are most often affected by iron deficiency anemia (IDA). Hemoglobin contains iron, which helps red blood cells to deliver oxygen to tissues. Therefore, if the iron in the baby’s body is not enough, the baby will be weak, and his body will practically not resist infections.
If the baby’s parents are attentive, then noticing them with IDA will not be difficult. At the same time, the child has a pale skin color, he quickly finds fatigue and lethargy, in addition, he noticeably lags behind in development in relation to his peers.
The optimal level of hemoglobin in a baby should correspond to 145 grams per liter until the end of the first month of life, and after six months this level should be 110 grams per liter. Continue reading
Painful, tactile, cold, thermal …
Our skin is one of the main senses. It contains a dense network of nerve fibers, and millions of the thinnest branches branch off from them, ending on the surface of the skin with sensitive nerve devices – receptors. On average, one square centimeter of skin accounts for 100 – 200 pain receptors, 12 – 15 cold receptors, 1 – 2 heat receptors, and about 25 tactile ones. They also translate various stimuli – mechanical, physical, chemical – into the universal electroimpulsive language of the nervous system.
The most common type of skin receptors are free nerve endings (13); they perceive mainly pain. There is practically no area on our skin where pain receptors are completely absent, but they are distributed unevenly. For example, axillary and inguinal areas are richly equipped with them, and the most “painless” ones are soles, palms, and auricles. Continue reading
