Hyponatremia Versus Heat Cramps
Hyponatremia versus heat cramps separates confused systemic low sodium from muscle spasms—water alone worsens hyponatremia; heat cramps often need salty fluids and rest.
Hyponatremia versus heat cramps distinguishes low blood sodium from painful muscle spasms in heat—both can occur on long humid efforts but treatments diverge. Hyponatremia brings confusion, bloating, and nausea; forcing plain water worsens it.
Heat cramps focus in muscles with heavy sweat; salty fluids and rest help many cases. Either can escalate to exertional heat illness.
Common questions
-
