How long would it take to safely accelerate to the speed of light without experiencing G-forces that would be destructive to the human body?

Assuming we ever do master lightspeed travel (or close as makes no difference), how long would the initial acceleration to that speed have to take for it to be safe for human passengers without any kind of advanced, hyperbaric safety mechanism?

It's a big coincidence that one year of Earth's gravitational acceleration classically gets you to the speed of light (however taking relativity into account, only 76%). So, to approach the speed of light, you need to accelerate with around 1 g for a bit more than a year. But you will never reach it.
