Heat illness or heat-related illness is a spectrum of disorders due to environmental heat exposure. It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke.Heat stroke is defined as a body temperature of greater than 40.6 °C (105.1 °F) due to environmental heat exposure with lack of thermoregulation. This is distinct from a fever, where there is a physiological increase in the temperature set point of the body.

Treatment involves rapid mechanical cooling.

A number of heat illnesses exist including:

Heat stroke presents with a hyperthermia of greater than 40.6 °C (105.1 °F) in combination with confusion and a lack of sweating.

Substances that inhibit cooling and cause dehydration such as alcohol, caffeine, stimulants, medications, and age-related physiological changes predispose to so-called "classic" heat stroke. Exertional heat stroke can happen in young people without health problems or medications, most often in athletes and military recruits.

Capital Lights is an American Christian pop rock band that was formed in 2002. They released two EPs and one album as afterEIGHT, and one full-length album, This Is an Outrage!, under their current name which was released by Tooth & Nail Records on July 8, 2008. It reached No. 28 on Billboard's Christian Albums chart. On Christmas Eve 2010, Bryson Phillips appeared on RadioU's morning show, The R!OT, and revealed that the band had plans to record one last album with Tooth & Nail, though not planning to tour in support of it.

The bandmates started the group in 2002 with the name afterEIGHT, after the demise of their previous group, known as twenty-4-seven.

The name afterEIGHT came to be when vocalist/bassist Bryson Phillips and guitarist Brett Admire worked in a small restaurant named Lee's Diner. After looking for a practice place, the owner allowed them to practice there as long as it was after eight o' clock. After weeks of saying "Practice tonight...after eight", the band chose the name afterEIGHT.

Man Parrish (born Manuel Joseph Parrish, May 6, 1958) is an American composer, songwriter, vocalist and producer. He, along with artists such as Yellow Magic Orchestra, Kraftwerk, Art of Noise, Arthur Baker, Afrika Bambaataa, John Robie, Jellybean Benitez and Aldo Marin helped create and define electro in the early 1980s^{[citation needed]}. He became an underground music scene icon in the 1980s and 1990s and is one of the most important and influential figures in American electronic dance music.^{[citation needed]}

A native New Yorker of Puerto Rican descent, Parrish was a member of the extended family that converged nightly at Studio 54. His nickname, Man, first appeared in Andy Warhol's Interview magazine, and his early live shows at Bronx hip-hop clubs were spectacles of lights, glitter, and pyrotechnics, which drew as much from the Warhol mystique as the Cold Crush Brothers. He pioneered a form of electro-hip-hop that dominated the post Disco, pre-House Music club scene of the early eighties and was a primary influence on the subsequent genres of House and Techno Music.
