The appearance of calf cramps in the middle of the night does not mean that you are growing taller. Most of the symptoms are caused by calcium deficiency, or cold, fatigue and other factors. If it occurs during the puberty stage, the first thing to consider is that it is caused by calcium deficiency. Due to the rapid development of the body during puberty, the body is relatively deficient in calcium. If this happens, you should pay attention to eating more calcium-rich foods in your diet, such as beans and milk, and you can also target calcium gluconate supplements. Participate in more outdoor sports and sunlight, which are good for the relief of symptoms. You also need to pay attention to keep warm and avoid cold and fatigue to prevent the symptoms.
