Ever since videos of Sunita Williams have emerged from the space station, there have been concerns about her health and fans and followers of the Indian origin astronaut are constantly worried about “the way she looks”.
Though there have been repeated assurances from Sunita about her health and also of her colleague, Butch Wilmore's concerns are still there.
Despite her regular workouts aboard the International Space Station (ISS), some observers have noted that she appeared to be "in bad shape". This perception stems not from a lack of effort but from the unique and challenging conditions of microgravity.

In microgravity, the body undergoes significant physiological changes. Without the constant pull of Earth's gravity, muscles and bones no longer need to work as hard to support the body or facilitate movement. This leads to muscle atrophy and bone density loss, particularly in weight-bearing areas like the legs and spine.
Even with vigorous exercise routines, astronauts experience these effects to some extent. Sunita Williams follows a strict regimen of workouts for almost 2 hours a day. However, these exercises can only partially counteract the deterioration caused by microgravity.
Bodily liquids shift toward the upper half of the body and face, giving a puffed appearance to the face and at the same time a shrunken appearance of the legs.
Fluid dynamics changes also affect the heart, as it does not have to work as hard to push blood around the body, there is a degradation in cardiovascular fitness over time. Even hours of exercise are no guarantee against an unwanted side effect of space living.
This altered sense of taste may result in astronauts consuming less food or fewer calories than they need to sustain the effort required for their physical activities. Therefore, even the best exercise plan may be insufficient if it is not supplemented with proper nutrition. Sunita Williams, like other astronauts, underwent a rehabilitation program to restore her physical health after her missions.
Sunita Williams has been stuck in space since June, this year. What was meant to be a space mission for a few days has extended to months. It is expected that Sunita and her colleague are likely to return to Earth in February 2025. Currently, she is spending her time properly by engaging in various activities like growing "Outredgeous" romaine lettuce in microgravity.
