Shivering

Shivering (also called shuddering) is a bodily function in response to early hypothermia or just feeling cold in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy. Shivering can also be a response to a fever, as a person may feel cold. During fever the hypothalamic set point for temperature is raised. The increased set point causes the body temperature to rise (pyrexia), but also makes the patient feel cold until the new set point is reached. Severe chills with violent shivering are called rigors. Rigors occur because the patient's body is shivering in a physiological attempt to increase body temperature to the new set point.

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. Therefore, this center becomes activated when the body temperature falls even a fraction of a degree below a critical temperature level.

Shudder (album)

Shudder is the fourth studio album by American rock band Bayside, released on September 30, 2008. Prior to its release, singer Anthony Raneri described the album as having a more alternative sound than their previous record The Walking Wounded. The title comes from a lyric in the track "I Can’t Go On".

On September 5, 2008, the album was leaked onto various file-sharing sites. The first single, "No One Understands", generated significant attention from fans through the band's MySpace page. The band had also played "I Think I’ll Be Ok" at shows during the summer of 2008.

Around September 22, 2008, the album was put up to stream on the band's MySpace page. On October 4, 2008, the music video for the song "No One Understands" was posted for viewing on the band’s official MySpace page.

"You’ve Already Been" was added as an iTunes bonus track, and later appeared on the Take Action! Vol. 8 compilation CD/DVD.
