In fact, research has demonstrated that excessive sweating can be a symptom of a vitamin D deficiency (4).  In general, sweating is nothing to worry about. When body temperature rises, due to exercise, stress, environmental heat, or hormonal changes, we sweat to bring our body temperature back into ideal ranges. However, excessive sweating, muscle weakness, hair loss and fatigue are vitamin D deficiency warning signs.
