What is useful for a vacation at sea?

A vacation by the sea has a lot of advantages and brings great benefits to everyone. It is especially easy to breathe on the seashore, since the air contains ozone and oxygen molecules, iodine ions, and a suspension of sea salts. All these components stimulate many vital processes, strengthening the immune system and increasing the body's resistance to infections. Do not forget that bathing, which gives us children's delight, is one of the ways to harden the body. Since the water temperature is always lower than body temperature, when bathing, the superficial blood vessels constrict, then, adapting, the vessels expand – and we feel warm. Thus, sea baths are a wonderful method of hardening, increasing immunity and preventing diseases. And sea bathing also increases the vitality and adaptive capabilities of our body. The marine climate is especially useful for improving the health of children and people weakened after illness or hard work.
