Do people in cold climates age better? The science behind temperature and longevity

Recent research in *Nature Aging* found that cold temperatures trigger a cellular cleansing mechanism that breaks down harmful protein deposits, a key factor in many age-related diseases. This discovery provides compelling evidence suggesting that, under controlled conditions, cold exposure may offer genuine anti-aging benefits. But does this mean people in cold climates age better? The answer is more complex, pitting the potential benefits of therapeutic cold against the actual risks of living in perpetually chilly conditions.
