When fear washes over you, gently place a warm palm on your heart or cheek. The moderate weight and warmth transmitted through your fingertips softly melt the hardened vagus nerve, sending a signal of quiet peace to the nervous system. Then, as you exhale, try letting out a very long and deep sigh. As your exhale lengthens, the pulse of your excited sympathetic nervous system subsides, and your body regains a safe rhythm.
