Peter fell ill on Thursday night after working in his parents' business in Lonoke County, said Pulaski medical geriatric surgeon Gerone Hobbs. He was brought to the Baptist Health Medical Center in North Little Rock just before 9pm. and was pronounced dead shortly before midnight, Hobbs said.
The temperature in the area reached 92 degrees during the day, and in Arkansas, a heat warning was in effect when Peter became ill. When body temperature rises faster than it cools, there is a "heat stroke" that can potentially damage the brain and other vital organs.
Petrus & # 39; s mother told the coroner that her son drank water while out working, but did not get enough electrolytes. Peter did not seem to have any pre-existing conditions, Hobbs said.
Sue's son and Phil Petrus, the former offensive linesman, lived in Carlisle, Arkansas, according to the New York Giants website. Petrus played for Carlisle High School and then for the Hogs, the University of Arkansas Razorbacks football team, where he graduated in 2009 with a degree in agriculture.
He contributed in February 201
2 to the snappy Super Bowl defeat of the New York Giants against the New England Patriots (21-17) at. Peter also played for the Tennessee Titans and the Patriots before leaving the NFL in 2013.  The Giants' website noted that Peter "had to fight for everything he earned on the football field" to earn "a good living in the Ultimate Fight Championship".  On Twitter
described himself as "the bassist for my band Vikings of the North Atlantic" and said that he assisted Senator Jonathan Dismang during the legislature's session in 2018.
] Responses to Peter's death included warnings of a potentially fatal heat stroke.
Warning signs of a heat disorder include a high body temperature, hot, red, dry or damp skin and a fast, strong heart rate, according to US Centers for Disease Control and Prevention. Later symptoms may include headache, dizziness, nausea, confusion, and unconsciousness. Extreme dehydration is also part of the heat stroke equation.
A cascade of physiological events occurs when a patient's organs begin to close and the body becomes unable to regulate blood pressure, and the blood does not clot. Many patients experience changes in their consciousness.
The treatment is to cool down quickly and return to body temperature as quickly as possible. Ice baths, ice packs and fans are all useful.
In general, people who work outdoors or do a lot of sports are more used to the heat and therefore are less likely to get sick. That is, anyone exposed to hot weather for too long may get sick.
Those who do not just want to get used to the weather but also want to avoid a heat stroke can wear loose-fitting clothing in the sun, drink plenty of water and make themselves comfortable on the hottest days of the day.
