Astronauts might need to use swimming goggles to save their vision as reduced pressure during space missions can lead to adverse changes in the eye, reveals a new study.
Long Duration In Spaceflights Affects The Spine Of Astronauts - NASA Study
Astronauts on long missions in space experience moderate to severe backache due to atrophy or shrinkage of the muscles supporting the spine.
Astronauts on long missions in space experience moderate to severe backache due to atrophy or shrinkage of the muscles supporting the spine.
‘Wearing goggles create mild pressure around the eyes and counteract the problem, caused due to a drop in pressure inside the eye. Modestly raising intraocular pressure with swimming goggles could help relieve spaceflight-associated neuro-ocular syndrome.’

This study included 20 men who on three separate days at NASA's Johnson Space Center in Houston completed exercises while on their back and tilted back head-first (to simulate the effect of exercise in space); 10 of the participants wore swimming goggles. Read More..
The Research team found exercise was associated with decreases in pressure in the eye, while the addition of swimming goggles was associated with modestly increased pressure, which could reduce some of the adverse effects on the eye of long-duration spaceflights.
These findings need to be replicated in spaceflight to determine whether increasing eye pressure with swim goggles is safe and effective.
Astronauts' Weight can Cause Eye Changes During Spaceflight
An astronaut's weight plays a key role in the visual changes, as gravity levels in space reduce and can lead to spaceflight-associated neuro-ocular syndrome (SANS) in some astronauts.

Long-Term Space Missions Don't Damage Immune Systems Of The Astronauts: Study
The immune system of an astronaut may not be damaged by long-term space mission, finds a new study. It was found that the B-cell immunity, a major aspect of the immune system was not compromised after a 6-month spaceflight.
