How do astronauts minimise G-force when they blast off?

Answer 1

One way is by lying perpendicular to the direction of the launch so that the blood does not rush away or towards the brain.

Answer 2

Astronauts minimize G-forces during blastoff by using specially designed seats that distribute the forces evenly across their bodies. Additionally, they undergo training to brace themselves and tense their muscles to help withstand the forces. The spacecraft's design also plays a role in minimizing G-forces by gradually accelerating and decelerating during launch and reentry.
