Turns out Vitamin C does more than just thwart colds: The nutrient also wards off sight-clouding cataracts. Dubbed “scurvy of the eye”, cataracts earned that moniker after research revealed that a deficiency in C can trigger their growth. Fortunately, Spanish investigators discovered that taking 500 mg. of Vitamin C daily reduces cataract risk by 64%, plus helps block their growth if you already have them. Researchers say that the nutrient prevents eye fluids from oxidizing and causing cloudy, blurred vision.
Next time your mind feels a little sluggish, hum your favorite tune. The vocal cords are connected to the vagus nerve, a key communication pathway linking the brain and other parts of the body (like the heart, lungs and stomach). Humming creates vibrations that stimulate the nerve, which spurs the release of acetylcholine, a compound that quickly clears away brain fog to sharpen thinking. For an even stronger vibration (and bigger mental boost), open and close your mouth while humming your favorite Motown song.
