You know the feeling. Your eyelids start to feel heavy, you have trouble concentrating, and your energy level plummets. The afternoon slump happens to many people. Take a break if you have been busy or working. You also need a change of scenery. There is nothing better than heading outside for about ten minutes. If you can, walk for a few minutes. The sunlight will boost your mood and help your body feel more energetic. You will also get a dose of vitamin D. Have a snack. Foods loaded with carbs will further deplete your energy level so try something rich in protein. You can also indulge in some dark chocolate. It is full of healthy fat and antioxidants and even has a small amount of caffeine.
