By the time a child is 4-8 years old, his sugar consumption skyrockets to an average of 21 teaspoons a day. The same study found 14-18 year old children intake the most sugar on a daily basis, averaging about 34.3 teaspoons.
In space, the body begins to adapt to the microgravity environment. NSBRIâs science and technology program is addressing ways to reduce or eliminate many of the changes to the body that impact an astronautâs ability to perform well in space and that might impact their health after returning to Earth.
Weightlessness causes several key systems of the body to relax, as it is no longer fighting the pull of gravity. Astronauts' sense of up and down gets confused, NASA said, because the vestibular system no longer can figure out where the ground and the ceiling are.
