Stretching and leg cramps may be caused by the following reasons. First, when muscles are in a relaxed state, stretching may cause these relaxed muscles to suddenly contract, leading to excessive contraction and resulting in leg cramps. Second, pay attention to cramps caused by calcium deficiency, as low blood calcium levels due to insufficient calcium can increase muscle tension, making cramping more likely. It is advisable to consume more calcium-rich foods or take calcium supplements appropriately.
