1. Increase Your Magnesium Intake. This mineral is needed for more than 300 biochemical reactions in the body, including breaking down glucose into energy, so when levels are even a little low, energy can drop. The recommended daily intake of magnesium is around 300 milligrams for women and 350 milligrams for men.
2. Take a walk. While it may seem as if moving about when you feel exhausted is the quickest route to feeling more exhausted, the opposite is true. Experts say that increasing physical activity, particularly walking, increases energy. In experiments conducted by Robert Thayer, PhD, at California State University, a brisk 10-minute walk not only increased energy, but the effects lasted up to two hours. And when the daily 10-minute walks continued for three weeks, overall energy levels and mood were lifted.
