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.
But in the microgravity of space, blood moves up to the chest and head, giving astronauts puffy faces and raised blood pressure. Muscles are also threatened by space travel. Without the need to work against gravity, muscles can start to waste, which increases the risk of tendonitis and fat accumulation.
