Space 'Levkoi',

Abstract

The flights of Soviet and American astronauts made it possible to note certain general regularities in well-being during the so-called transition period - during the first days of flight when the organism is becoming adjusted to the conditions of weightlessness. Gravity is absent, the heart does not have to expend energy for raising the blood from the lower parts of the body to the upper. But the heart still doesn't know about this and it continues to pump blood as it pumped it on earth. There is a redistribution of blood. An excess of it, making up around eleven percent, flows into the chest cavity and into the brain. In some this redistribution doesn't have any effect on efficiency. Others experience a heaviness in the head, they become motion sick, and naturally it is more difficult for them to work in space.
