astronaut eyes

Post by Cece » 1 year ago

More information on the damage to astronaut eyes during long term spaceflight. It was on CNN's website so probably fake news. Just kidding. Thought this was interesting, the idea that eyes act like a pressure release valve to a brain that has too much cerebrospinal fluid pressure.

Given the connection between the eye, the optic nerve and the brain, combined with the fluid shift astronauts experience, some research has suggested that the eyes act as a pressure release valve. But further study is needed.
This causes something known among astronauts as Bird Leg Syndrome, because the fluid shift causes them to have puffy faces and thin legs. It also makes them less thirsty, dulls their sense of taste and causes a "stuffy nose" feeling similar to allergies.
Why is sense of taste affected? I had my sense of taste improved immediately after CCSVI treatment. Still a weird effect.

NASA and others have used a bed rest model to induce the adverse effects of microgravity on astronauts. Prolonged bed rest, both flat and head down cause the same degeneration as being in space!

Given this connection with bed rest, isn't it time to "wake up" to the fact that gravity is vitally important to maintaining all of our vital functions and circulations?
