Why are astronauts placed in a horizontal position during take off?

Astronauts are placed in a horizontal position during takeoff to help distribute the forces acting on their bodies more evenly. This position minimizes the impact of acceleration on their cardiovascular systems, reducing the risk of G-force-induced loss of consciousness. Additionally, it allows for better stabilization and comfort during the intense launch phase, ensuring that astronauts can maintain focus and respond effectively to any situations that arise.
