In summer, everyone strives for the beach, closer to the sea, river or lake, to enjoy sunbathing, soak in the warm sand and get a beautiful, even and mouth-watering tan. But it is worth noting that not everyone can sunbathe. People with high blood pressure and diabetes should generally be exposed to the sun as little as possible: there is a risk of worsening chronic diseases, as well as an additional burden on the heart and blood vessels. Small children and adolescents can also be exposed to scorching rays for no more than an hour – their fragile body can experience serious stress. There are special people suffering from albinism – they do not have melanin, which gives color to the skin, eyes, hair. In principle, they should not be in contact with the sun. But do not forget about ordinary people: if you are in the sun for a long time, then there is a risk of sunstroke and dehydration. Therefore, everything must be approached wisely. Continue reading

Children’s hardening is based on the property of the body to gradually adapt to unusual conditions. The transition from weaker tempering procedures to stronger ones (due to lowering the temperature of air, water, increasing the duration of the procedure) must be carried out gradually. Hardening has a general strengthening effect, improves blood circulation, increases the tone of the nervous system, and normalizes metabolism. In the process of hardening, conditioned reflexes are formed and fixed, which contribute to the formation of protective reactions. Thanks to this, the child’s body is able to adapt to changing conditions and painlessly endure excessive cooling, overheating and other adverse effects. With repeated and systematic use of cold water, heat generation increases, skin temperature rises, the stratum corneum thickens, and the intensity of irritation of the receptors located in them decreases. All this increases the adaptation of the child’s body to Continue reading
