[MCU] How do the jumps through interstellar space work?

We see in GOTG2 that ships use some sort of jump points to travel through space. How do they work? And why does making multiple jumps cause such effects to people?

We don't know.  We do know that the jumping warps reality for the traveler.  We also know that this sort of travel is visible as a moving speck of light from the perspective of a distant observer.  The ship seems to travel under its own power, moving between 'gates' that seem temporary, maybe even generated by the ship, rather than between fixed hardware installations.  The gates seem to work like lenses, vastly accelerating and distorting the ship in transit, and then restoring it to normal space upon exit.
