Shiver

Lore & Background

Shiver was one of the earliest songs Coldplay wrote after forming in 1996, and it quickly became a staple of their live sets before Parachutes was released. The song's raw, emotional delivery and the iconic opening guitar riff helped establish the band's signature sound. It was released as a single in the UK on March 6, 2000, and later included on the album Parachutes, where it served as the second track. The music video, directed by Grant Gee, features the band performing in a dimly lit room intercut with abstract imagery, reflecting the song's themes of longing and uncertainty.

In Their Own Story

The rain taps against the windowpane, a steady rhythm matching the frantic beat inside his chest. He sits at the piano, fingers hovering over keys that feel too cold to touch. Every note he plays seems to echo the trembling in his hands, a physical manifestation of the words he is afraid to speak. Outside, the world moves on, indifferent, but here in this small room, the air is thick with unspoken fears and the desperate hope that maybe, just maybe, she can feel it too.

Reader's Guide

Located in the posterior hypothalamus near the wall of the third ventricle is an area called the primary motor center for shivering. This area is normally inhibited by signals from the heat center in the anterior hypothalamic-preoptic area but is excited by cold signals from the skin and spinal cord and becomes activated when the body temperature falls even a fraction of a degree below a critical temperature level. The center then causes rapid contractions of skeletal muscles, producing heat as a byproduct. Newborn babies, infants, and young children experience a greater (net) heat loss than adults because of a greater surface-area-to-volume ratio. As they cannot shiver to maintain body heat, they rely on non-shivering thermogenesis. Children have an increased amount of brown adipose tissue (increased vascular supply and high mitochondrial density), and, when cold-stressed, will have greater oxygen consumption and will release norepinephrine. Norepinephrine will react with lipases in brown fat to break down fat into triglycerides. Triglycerides are then metabolized to glycerol and non-esterified fatty acids. These are then further degraded in the needed heat-generating process to form CO2 and water. Chemically, in mitochondria, the proton gradient producing the proton electromotive force that is ordinarily used to synthesize ATP is instead bypassed to produce heat directly. Shivering can also appear after surgery. This is known as postanesthetic shivering. In humans, shivering can also be caused by cognition. This is known as psychogenic shivering. The functional capacity of the thermoregulatory system alters with aging, reducing the resistance of elderly people to extreme external temperatures. The shiver response may be greatly diminished or even absent in the elderly, resulting in a significant drop in mean deep body temperature upon exposure to cold. Standard tests of thermoregulatory function show a markedly different rate of decline of thermoregulatory processes in different individuals with ageing.
