what does dealing with excess temperatures include

Relative humidity - The ratio of the water vapour content of air to the maximum possible water vapour content of air at the same temperature and air pressure. Overview Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. Though few studies have evaluated the efficacy of heat notification and response programs, one study concluded that during a 1999 heat wave Chicago more successfully mitigated adverse effects than it did during a 1995 heat wave (about 100 deaths in 1999 compared with approximately 700 deaths in 1995). Both wet-bulb temperature and heat index are calculated using data on air temperature and humidity -- the two most important factors that affect heat stress. Muscle cramps, pain, or spasms in the abdomen, arms, or legs. Since 2005, wet-bulb temperature values above 95 degrees Fahrenheit have occurred for short periods of time on nine separate occasions in a few subtropical places like Pakistan and the Persian Gulf.

A change of body temperature of more than 1C occurs only during illness or when environmental conditions are more than the body's ability to cope with extreme heat. With too many greenhouse gases, Earth would be like Venus, where the greenhouse atmosphere keeps temperatures around 400 degrees Celsius (750 Fahrenheit). Between 105 and 130F (40 and 54C), heat exhaustion is more likely. As temperatures rise, mass coral bleaching events and infectious disease outbreaks are becoming more frequent. WBGT also uses temperature and humidity data, but factors in wind speed, sun angle, and cloud cover (solar radiation), variables for which reliable data are limited across much of the globe. Called metabolic heat, it is generated within the body by the biochemical processes that keep us alive and by the energy we use during physical activity. A person with a spinal cord injury may have difficulty in extreme heat no matter what treatment they choose. In moderately hot environments, the body "goes to work" to get rid of excess heat so it can maintain its normal body temperature. Raymond noted that people die of heat stress at wet-bulb temperatures much lower than 95 degrees Fahrenheit (35 degrees Celsius). (2014, November 25). Heat also has important indirect health effects.
