How many g-forces can a human withstand?

Answer 1

the healthy human body with some practice at pulling g, could withstand only a few seconds at more than 10 g before passing out from lack of blood flow to the brain. Or, more aptly, the lack of oxygen to feed the brain that only blood flow could provide. The heart can only beat against so much pressure before it losses the battle. Rookies couldn't hope to withstand more than about 5 or 6 g before losing consciousness.

Answer 2

The amount of g-forces a human can withstand varies depending on the direction of the force and the duration of exposure. In general, humans can withstand up to 5 g-forces for a brief period of time without losing consciousness. However, prolonged exposure to high g-forces can lead to serious health risks such as organ damage or death. Pilots and astronauts are trained to withstand higher g-forces using specialized equipment and techniques.
