Know why astronauts age slower in space than people on Earth

According to Einstein's theory of relativity, time passes differently for objects moving at different speeds. Astronauts in space travel at high speeds, causing time to dilate, making them age slower relative to people on Earth.

In space, away from the strong gravitational field of Earth, time moves slightly faster. This effect contributes to astronauts ageing slower.

The weaker gravitational force in space compared to Earth's surface also contributes to the slower ageing of astronauts. Gravity affects the passage of time, and weaker gravity results in slower ageing.

Astronauts experience less stress on their bodies in the microgravity environment of space, which can lead to slower ageing.

Stress can accelerate the ageing process, so the reduced stress in space contributes to slower ageing.

Space missions involve highly controlled environments, including diet, exercise, and medical care, which can slow down the ageing process.
