A retrospective cohort study conducted in Stockholm reveals a strong, direct association between high outdoor temperatures and the occurrence of severe hyponatremia, defined as a serum sodium concentration below 125 mmol/L. These findings, based on robust data collected over 14 years, highlight vulnerable populations—women and the elderly—and project a significant increase in the burden of this condition by 2050 due to climate change and population aging.
