First Aid Safety Tips for Muscle Cramps

Heat cramps are sudden, painful muscle cramps that are caused due to exposure to very high temperatures for prolonged periods with increased physical activity and less hydration. When a person works or exercises in a hot environment, he loses a lot of body fluid and electrolytes through sweat. Inadequate intake of fluid and electrolytes aggravates the condition. These occur for a brief period but are very painful.

Heat cramps are known to occur during sleep after heavy work. This is due to release and build up of chemical waste

in the muscles e.g., calves, thigh, foot, shoulder etc.
