Effects of Prolonged Space Exploration

Bone Density Loss

Bone density loss occurs due to a lack of gravity, making bones brittle and prone to fractures upon return to Earth.

Muscle Weakness

Muscle atrophy happens as muscles don`t work as hard in space, leading to weakness and reduced physical performance.

Weak Heart

Cardiovascular deconditioning can occur, where the heart weakens and blood pressure regulation is affected by microgravity.

Exposure to Radiation

Radiation exposure in space increases the risk of cancer and other health issues due to the lack of Earth`s protective atmosphere.

Altered Vision or Blindness

Vision problems, known as Spaceflight-Associated Neuro-ocular Syndrome (SANS), can develop due to fluid shifts in the body.

Immunity Problems

Immune system dysfunction may occur, making astronauts more susceptible to infections during and after spaceflight.

Psychological Issues

Psychological effects like stress, anxiety, and sleep disturbances can arise from isolation and the demanding environment.
