3. Muscle Cramps

Dehydration can cause muscle cramps and spasms, especially during physical activity. When you’re dehydrated, the electrolyte balance in your muscles is disrupted, leading to involuntary contractions. Drinking water before, during, and after exercise helps prevent muscle cramps and supports optimal muscle function.

4. Rapid Heartbeat

In severe cases of dehydration, the body struggles to maintain normal blood circulation, leading to an increased heart rate. Dehydration causes a decrease in blood volume, forcing the heart to work harder to pump oxygen and nutrients to the body’s tissues. This can result in palpitations or a sensation of rapid heartbeat.
