2. Increase Your Iron Intake
There are numerous ways to keep your energy levels in winter high and perky. Lack of iron commonly affects women more than men, because women who experience heavy periods are often suffering from iron deficiency, a condition that only robs them of energy, makes them irritable and tired, but can also lead to serious conditions such as anemia. You can either take iron tablets to supplement your iron intake, or turn to proven iron-sources like leafy green vegetables, red meats and nuts. If you like smoothies, switch to the green variety in the morning - they contain the essential vitamins and nutrients that will keep your energy levels high for the rest of the day.
