Tranquility over stress
Lightning occurs when particles collide, creating an influx of negative charge that settles in the bed of a cloud. This creates a positive charge in the ground below, causing a giant spark between the sky and earth.
Stress is a response to pressures in your daily life. An accumulation of stress, like an accumulation of negative charge in a cloud, can cause sparks in your body which manifests itself in an overproduction of the major stress hormones– adrenaline, cortisol, norepinephrine. When produced in excess, these hormones throw off the body's equilibrium putting you at risk for anxiety, weight gain, heart disease and low libido.
