Can calcium deficiency in a 14-year-old boy cause depression and reversed sleep patterns?
Generally speaking, whether calcium deficiency in a 14-year-old boy can cause depression and reversed sleep patterns depends on the specific circumstances and requires comprehensive analysis. If related symptoms are present, it is recommended to seek medical evaluation promptly to identify the underlying causes. The detailed analysis is as follows:

If the boy has severe calcium deficiency leading to abnormal nerve excitability and poor sleep quality, chronic insomnia or light sleep may trigger low mood, resulting in symptoms resembling depression. Calcium also plays a role in regulating the biological clock; a significant deficiency may disrupt sleep rhythms, causing reversed day-night sleep patterns. In such cases, calcium deficiency could be one of the contributing factors to depressive symptoms and sleep disturbances.
However, if the calcium deficiency is mild, or if depressive symptoms are prominent and sleep reversal persists for a long time—accompanied by reduced interest, social withdrawal, and similar signs—these issues are generally not directly linked to calcium deficiency. Depression is more commonly associated with psychological stress and hormonal changes during puberty, while disrupted sleep patterns may result from irregular routines or emotional problems, necessitating investigation into other potential causes.
In daily life, include calcium-rich foods such as milk and soy products, and encourage appropriate outdoor activities to enhance calcium absorption. Help the boy establish a regular sleep schedule, avoid electronic devices before bedtime, and create a quiet sleeping environment. Pay attention to his emotional changes, communicate patiently, and help relieve stress. If symptoms persist, seek timely medical evaluation and intervention.
