If you find yourself feeling tired and foggy lately, your liver may be to blame. As many as 80% of women have fat buildup in the all-important organ, which causes a pileup of toxins that leave us feeling fatigued. To the rescue: bitter foods. They help restore liver function by boosting the production of compounds that help flush fat from the liver. To get the benefits, aim to enjoy at least 2 cups of bitter greens, like arugula, mustard and dandelion greens, chard or watercress, each day.
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.
