🔍 Key Concepts

• Difference between salt loss and water loss during heavy sweating • How the body’s electrolytes (especially sodium) affect muscle function • What happens when you take too much vs. too little salt after exertion

💭 Think About

• Think about what is being lost most during profuse sweating in a hot space: is it mainly water, salt, or both, and which one directly affects muscle spasms? • Which option best matches the idea that the body’s normal salt–water balance is being disturbed in a way that causes muscles to cramp? • Consider whether adding ‘excess’ of something would likely relieve cramps or actually make the body’s balance worse.

✅ Before You Answer

• Identify which choices describe loss of something versus excess intake of something • Ask yourself which condition is most commonly linked with muscle cramps after heavy sweating • Eliminate any choice that does not clearly connect to electrolyte (salt) imbalance in muscles
