Sunita Williams: Health issues she may face after returning to Earth

Astronaut Sunita Williams is set to return to Earth after spending nine months in space. Living in a zero-gravity environment for an extended period significantly affects the human body. Here’s a look at the health challenges she may encounter after landing.

Changes in Bone Density
One of the biggest concerns for astronauts is bone density loss. Bones weaken over time without gravity. Sunita Williams may need months of physical therapy to regain her bone strength.

Impact on the Heart
In space, the heart works less since there is no gravity pulling blood downward. This leads to changes in blood circulation. When astronauts return then they might feel dizzy as well as fatigued and experience swelling in the face due to fluid shifts.

Vision Problems
Many astronauts report blurred vision after space travel. This happens because fluid builds up in the skull putting pressure on the eyes. Sunita Williams may have to use glasses if her vision changes permanently.

Skin Sensitivity
Space suits and floating movements cause less contact with clothes making the skin softer and more sensitive. Once back on Earth astronauts mostly feel uncomfortable in regular clothing and some even develop skin allergies.

Psychological Adjustments
After months in isolation and microgravity, returning to Earth’s gravity can feel overwhelming. Sunita Williams will require mental and emotional support to readjust to daily life.

Sunita Williams is now 59 years old and has inspired millions with her achievements. As she returns experts will closely monitor her health recovery to understand the long-term effects of space travel.
