infections and other illnesses accompanied by fever, vomiting, or reduced fluid intake can disturb the body's fluid and electrolyte balance. In susceptible individuals, these disturbances may contribute to acute kidney injury. People with chronic kidney disease require particular attention to fluid intake because their needs vary according to disease severity and medical recommendations. Several preventive measures can help protect kidney health during cold weather. These include maintaining body warmth, consuming adequate fluids according to individual medical needs, monitoring blood pressure, and avoiding unnecessary use of medications that may harm the kidneys, particularly nonsteroidal anti-inflammatory drugs (NSAIDs).
