Which two lifestyle factors primarily increase the body's *demand* for magnesium rather than acting as direct diuretics?
Answer
Chronic Stress (via cortisol production) and Intense Activity (via energy production needs).
Magnesium loss occurs through two main pathways: direct excretion (diuresis) or increased consumption due to elevated demand. Caffeine and alcohol are known diuretics that cause flushing via urine. However, chronic stress and intense physical activity elevate the body's need for magnesium. In response to chronic stress, the body produces hormones like cortisol, and the synthesis and action of these hormones actively consume stored magnesium. Similarly, high-intensity exercise requires significant magnesium to facilitate energy production pathways, resulting in substantial loss through sweat and subsequent urinary losses post-workout.
