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.
Gravity pulls downward which supplies blood to the lower limbs. Microgravity pushes the blood to the upper portions of the body. The effects of microgravity isn't a big deal until astronauts travel back to Earth. Gravity pulls back the blood pressure down, but all the blood will transfer down to the astronauts' legs. This will cause other parts of the body to not have the blood they need to support the functioning of the astronauts' upper portion of their bodies.
