"Commander Alexandr Viktorenko, Flight Engineer Yelena Kondakova, and cosmonaut Valeri Polyakov, who set a new record for human space flight duration with his 438-day stay." 1995
There is no exact limit to how long a human can stay in space, as it depends on various factors such as the individual's health, access to resources, and spacecraft conditions. The longest consecutive time a human has spent in space is 438 days, by Russian cosmonaut Valeri Polyakov.

The longest time anyone has stayed in space continuously is 437 days, achieved by Russian astronaut Valeri Polyakov. He spent this extended period aboard the Mir space station from January 1994 to March 1995.
A cosmonaut spent 438 days living and working aboard the International Space Station (ISS). This extended mission involved conducting scientific research, performing maintenance tasks, and participating in various experiments in microgravity. The ISS serves as a unique laboratory for studying the effects of long-term space travel on the human body and conducting various scientific investigations.
438 days is equivalent to 1 year and 73 days. This can be calculated by noting that a year typically has 365 days, so when you subtract 365 from 438, you are left with 73 days. Therefore, 438 days spans over a year and an additional two months and a few days, depending on the specific months involved.
The longest single spaceflight duration was 438 days by cosmonaut Valery Polyakov aboard the Mir space station from 1994 to 1995.
