A relaxing, infused bath can super-charge immunity. How it works: Soaking in warm water spiked with apple cider vinegar raises the body’s pH to an optimal level, which makes the body a less hospitable environment for bacteria and viruses. I recommend doing the following twice a week during cold and flu season: Run a tub of the hottest water you can tolerate. Add 2 cups of organic apple cider vinegar. Soak until the water is cool, then don’t shower for at least 4 hours afterward to allow the vinegar to soak into your skin.
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.
