Dehydration Drives Summer ER Visits as 60% Water Body Faces Rapid Heat Strain

Summary
Emergency physicians say dehydration is a leading reason patients land in ERs during summer, with fluid loss in heat quickly escalating from headaches and fatigue to fainting and dangerous blood-pressure drops.
About 60% of the body is water, and sweating strips out both fluids and electrolytes; when losses outpace intake, urine darkens, sweating falls off and core temperature can climb toward heat illness.
Doctors warn thirst is already a late signal of dehydration, especially for older adults, children, outdoor workers and athletes, whose fluid deficits can build before they feel the need to drink.
Heavy sweating may require electrolytes as well as water, since replacing only fluids can dilute sodium and trigger hyponatremia; high-water foods such as watermelon at 92% and cucumbers at 95% can also help.
Confusion, chest pain, shortness of breath or fainting mark a medical emergency requiring 911 and likely IV fluids, while milder cases can often be treated with rest, cooling and steady rehydration.
