Every human wants to live a longer life to fulfil their dream and ambitions. While modern lifestyle stresses have raised health concerns, a breakthrough suggests we could far exceed current limits. According to Worldometer, the current global average life expectancy in 2026 is 73.8 years for both combined sexes (male and female). And a research team at the University of Rochester in the United States have discovered an abundant protein called CIRBP for whales’ longevity that helps repair DNA for centuries. The Rochester team worked with the scientists of Alaska on the bowhead whale project, but Vera Gorbunova (Co-director, Rochester Ageing Research Centre) said that “This research shows it is possible to live longer than the typical human lifespan.”

Can humans activate the same longevity protein as whales

“There are different ways to improve genome maintenance, and here we learn there is one unique way that evolved in bowhead whales where they dramatically increase the levels of this protein,” Gorbunova says while adding that “Now we have to see if we can develop strategies to upregulate the same pathway in humans.” As per the Rochester team, Gorbunova may have said this too early, but her suggestions of exploring ways to boost the human body’s CIRBP activity can open chances for humans to live longer. In this detail, it is mentioned that humans might be able to nudge their own CIRBP levels upward through lifestyle changes, like cold showers or cold-temperature exposure.

Why a cold shower might save human DNA

The CIRBP protein found in these whales is cold-inducible, which scientifically means that it will only wake up when the body feels the cold. The DNA in Bowhead whales is always working in a freezing environment. Scientists are now actively working on the cold trick that could work on human cells to produce more CIRBP.

Whale Mystery: Why the world’s largest mammals barely ever get cancer

The bowhead whale is called the world’s longest-living mammal, and it should have no further doubts because some of these giant whales are estimated to live more than 200 years. But living to this huge age, they never develop any age-related diseases such as cancer. Scientifically, larger animals do have trillions more cells than humans, which indirectly suggests they may have more diseases than humans over their lifespans. Still, such large animals or mammals seem to possess “hidden defences” that allow them to avoid cancer entirely. Their ability to survive without any major disease is also a built-in skill in cells. A whale’s cells fix the serious DNA breaks with perfection, and that allows its tissue to stay healthy for over two centuries.
