We rely on our devices to communicate, but the electromagnetic frequencies (EMFs) our cellphones and laptops emit can trigger fatigue, brain fog, and insomnia. That’s because EMFs increase the body’s production of free radicals that damage DNA and other cellular proteins. The easy fix? Holding your phone 1 inch from your ear when you’re talking cuts EMF exposure by 75% say scientists at the University of Utah. Also smart: stashing it in a handbag rather than your pocket and leaving it in the kitchen overnight.
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.
