Muscle Cramps or Weakness
Muscle cramps or weakness occurs when the effort you put into an action does not produce a regular muscle movement or contraction. In some cases, it’s called weak muscles, reduced muscle strength or muscular weakness. A cramp is usually sudden, unintended and brief, as it occurs from contraction of a muscle or a set of muscles that can be quite painful. Some known causes of muscle cramps include dehydration and having low amounts of electrolytes such as calcium, potassium or magnesium [2], and these are all associated with heat exhaustion.
