Having muscle cramps can be annoying, frustrating, and painful. Typically, people will try stretching or using massage techniques to relieve their symptoms, but what you really need might be much simpler.
While there is some disagreement on this, some studies have shown a relationship between dehydration and muscle cramping. Apparently, our blood circulation slows down when we drink too little water. As our bodies compensate for the lack of hydration, fluid is moved away from our muscles in an effort to protect our vital organs.
Things can be exacerbated further if our sodium and potassium levels begin to change due to sweat loss. This is why it's crucial that we consume enough water every day, but especially in hot weather and when we are exercising.
