Grazing at red clears brain fog. According to experts, that's the fastest way to shake off the mental fuzziness that always tends to set in, especially on busy days. Simply stare at something red, like red flowers, red paintings, a tablecloth or anything that's red for about a minute. Yup, that's all it takes to sharpen your brain power and increase stamina levels. Focusing on the color increases the production of energizing brainwaves, helping you feel clear headed and alert in no time. Warning: You shouldn't stare at any red hue, while eating; it increases your appetite.
