(AP)\u2014The Southwestern U.S. is bracing for another week of blistering temperatures, with forecasters on Monday extending an excessive heat warning through the weekend for Arizona\u2019s most populated area, and alerting residents in parts of Nevada and New Mexico to stay indoors.<\/p>\n<p>The metro Phoenix area is on track to tie or to break a record set in the summer of 1974 for the most consecutive days with the high temperature at or above 110 degrees Fahrenheit (43 Celsius). Even the morning low temperatures are tying historic records.<\/p>\n<p>Along the U.S.-Mexico border, federal agents reported that extreme temperatures over the weekend contributed to 45 people being rescued and another 10 dying.<\/p>\n<p>With so many consecutive days of excessive heat, forecasters, physicians and local health officials throughout the Southwest are recommending that people limit their outdoor exposure and know the warning signs of heat illness.<\/p>\n<p>Knowing the signs<\/p>\n<p>From heavy sweating and dizziness to muscle spasms and even vomiting, experts say heat exhaustion and heat stroke are likely to become more common. In coming decades, the U.S. is expected to experience higher temperatures and more intense heat waves.<\/p>\n<p>Heat stroke is the most serious heat-related illness and happens when the body loses its ability to sweat.<\/p>\n<p>The skin gets hot and red, and the pulse quickens as the person\u2019s body temperature climbs to 103 F (39 C) or higher. Headaches set in, along with nausea, confusion and even fainting.<\/p>\n<p>Jon Femling, an emergency medicine physician and scientist at the University of New Mexico, said the body tries to compensate by pumping blood to the skin as a way to cool off. And the more a person breathes, the more they lose fluids, becoming increasingly dehydrated.<\/p>\n<p>Important electrolytes like sodium and potassium also can be lost when sweating.<\/p>\n<p>\u201cSo one of the first things that happens is, your muscles start to feel tired as your body starts to shunt away,\u201d he said. \u201cAnd then you can start to have organ damage where your kidneys don\u2019t work, your spleen, your liver. If things get really bad, then you start to not be perfusing your brain the same way.\u201d<\/p>\n<p>Experts say it\u2019s important to recognize the signs of heat stroke in others, as people may not realize the danger they\u2019re in because of an altered mental state that may involve confusion.<\/p>\n<p>In the case of heat stroke, experts suggest calling 911 and trying to lower the person\u2019s body temperature with cool, wet cloths or a cool bath.<\/p>\n<p>With heat exhaustion, the body can become cold and clammy. Other signs include heavy sweating, nausea, muscle cramps, weakness and dizziness. Experts say the best thing to do is to move to a cool place, loosen clothing and sip some water.<\/p>\n<p>Older people, children and those with health conditions can face greater risks when the temperatures are high.<\/p>\n<p>During extreme heat events, one of the most common ways people can die is from cardiovascular collapse, experts said, because of the extra energy the heart has to expend to help the body compensate for the hot temperatures.<\/p>\n<p>In general, health officials say staying indoors, seeking air-conditioned buildings and drinking more water than usual can stave off heat-related illnesses. Caffeine and alcohol are no-nos. Eating smaller meals more often throughout the day can help.<\/p>\n<p>Learning the limits<\/p>\n<p>Researchers at Arizona State University are trying to better understand the effects of extreme heat on the body and what makes hot weather so deadly.<\/p>\n<p>They\u2019re using a special thermal mannequin called ANDI that is outfitted with nearly three dozen different surface areas that are individually controlled with temperature sensors and human-like pores that produce beads of sweat.<\/p>\n<p>\u201cA lot of research that I and my colleagues do is just really focused on understanding how people are responding to higher levels of extreme heat over longer periods of time and then what we can do about it,\u201d said Jenni Vanos, an associated professor at ASU\u2019s School of Sustainability.<\/p>\n<p>There are 10 thermal mannequins in existence, with most used by athletic clothing companies for testing. ASU\u2019s manikin is the first that can be used outdoors thanks to a unique, internal cooling channel.<\/p>\n<p>The university also has developed a new \u201cwarm room,\u201d or heat chamber where researchers can simulate heat-exposure scenarios from around the globe. Temperatures can reach 140 F (60 C) inside the room\u2014and wind and solar radiation can be controlled for experiments.<\/p>\n<p>Vanos said measuring short- and long-wave radiation in the environment can also tell researchers how much a surface\u2014or a person\u2014in a specific location of a city would heat up.<\/p>\n<p>\u201cAnd so under these extreme conditions, what\u2019s going to really be able to be modified or changed within the urban environment is shade,\u201d she said. \u201cIn a place like Phoenix or really any sunny hot area, shade is a really critical factor to be able to reduce that overall heat load of the human body.\u201d<\/p>\n<p>Finding relief<\/p>\n<p>While air conditioners are cranked up and fans are blowing full blast, residents across the region are anxiously awaiting the start of the monsoon season, hoping it will help to keep the heat at bay.<\/p>\n<p>But so far, the summer thunderstorms\u2014which usually bring cloud cover, lightning and downpours to the Southwestern desert\u2014are absent due to the ongoing El Ni\u00f1o weather pattern, National Weather Service meteorologist Sam Meltzer said.<\/p>\n<p>\u201cIt looks like things are going to be abnormally dry over the next couple of months,\u201d Meltzer said, noting that storms that might break the heat depend on wind patterns drawing moist air from the Gulf of California into Arizona, New Mexico and Nevada.<\/p>\n<p>\u201cBut that doesn\u2019t mean we aren\u2019t going to get thunderstorm activity,\u201d Meltzer said. \u201cIt just might be delayed.\u201d<\/p>\n<p>Meltzer worked in Phoenix before transferring last winter to Las Vegas. He noted that while temperatures rose last month in the Phoenix area, June stayed abnormally cool in southern Nevada.<\/p>\n<p>The official daytime temperature at Harry Reid International Airport in Las Vegas remained below 100 F (37.8 C) for a record 294 days before temperatures reached 102 F (38.9 C) on June 30. The previous record of 290 days, from 1964 to 1965, had stood for 58 years.<\/p>\n<p>Still, it\u2019s not just the air temperature that people need to worry about, Vanos said. Humidity can make it more difficult for the body to use sweating as a way to cool off.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ALBUQUERQUE, N.M.
