美国国家公园管理局表示，一名青少年在大峡谷徒步时出现热射病相关症状后死亡。
据公园管理局消息，该青少年于周三在大峡谷布赖特安杰尔步道的一段区域身亡。该局在一份声明中表示，当地时间当天下午1点40分左右，有人报告称一名18岁男性在峡谷深处的一段步道上出现热射病症状。据大峡谷保护组织介绍，他已经徒步走过了哈瓦苏派花园——该休息站和露营地本身就需要从峡谷边缘向下徒步3000英尺。
公园管理局表示，护林员立即启动直升机救援行动，最终在步道下方约30英尺的一处偏远区域找到了这名青少年。他们尝试了救生措施，但未能成功。
工作人员尚未公布这名18岁男子的姓名，并于周六表示，仍在等待通知其近亲。
公园管理局表示，这名青少年原本计划从峡谷南缘出发，往返徒步至科罗拉多河，这正是布赖特安杰尔步道的路线。公园管理局称该步道是其最热门的峡谷徒步路线，但同时建议不要在一天内完成全程往返徒步。
“哈瓦苏派花园以下的目的地不建议作为单日徒步路线，因为距离过长、气温变化极端，且单程海拔落差约5000英尺（1500米），”公园管理局官网写道。该网站还建议徒步者在尝试单日往返哈瓦苏派花园前“向公园护林员咨询”，因为仅这段行程就有9英里，需要6至9小时才能完成。
公园管理局表示，科科尼诺县法医办公室正在对该青少年的死亡展开调查。
美国疾病控制与预防中心指出，当人体暴露在极端高温环境下时，就可能患上热射病。其中最严重的热射病属于医疗急症，可导致残疾或死亡。
疾控中心警告称，当人出现热射病时，体温会快速升高，在短短10至15分钟内就能达到106华氏度甚至更高，且身体无法自行降温。热射病的症状可能包括意识混乱、言语不清、失去意识、大量出汗和抽搐。
Teen dies after showing symptoms of heat-related illness on strenuous hike through Grand Canyon

A teenager died after experiencing symptoms of heat-related illness while hiking in the Grand Canyon, the National Park Service said.
The teen died Wednesday along a stretch of the Grand Canyon’s Bright Angel Trail, according to the park service. It said in a statement that rangers received reports at around 1:40 p.m. local time that day “of an 18-year-old male experiencing heat-related symptoms” on a portion of the trail deep within the canyon. He had hiked past Havasupai Gardens, a rest stop and campground that already requires a 3,000-foot descent from the canyon rim, according to the Grand Canyon Trust.
Rangers rushed to launch a helicopter rescue operation and ultimately found the teen about 30 feet below the trail, in a remote area, the park service said. They attempted life-saving measures but were unsuccessful.
Officials have not released the 18-year-old’s name, saying Saturday that notifications remained pending to his next of kin.
The park service said the teen had intended to complete a round-trip day hike from the South Rim of the canyon to the Colorado River. That’s the route of the Bright Angel Trail, which the park service says is its most popular hiking trail into the canyon, though it recommends against hiking all the way to the bottom and back in a single day.
“Destinations below Havasupai Gardens are not recommended day hikes due to the long distance, extreme temperature changes, and an approximately 5,000′ (1,500 m) elevation change each way,” the park service’s website said. The site also advises hikers to “check with a park ranger” before attempting to hike to Havasupai Gardens and back in a day, as that trek alone is 9 miles and takes between six and nine hours.
An investigation into the teen’s death is underway at the Coconino County Medical Examiner’s Office, the park service said.
Heat-related illnesses can occur when a person is exposed to extreme heat. The most serious of them, heat stroke, is a medical emergency that can cause disability or death, according to the Centers for Disease Control and Prevention.
When someone experiences heat stroke, their body’s temperature rises rapidly, potentially reaching 106 degrees Fahrenheit or higher in as little as 10 or 15 minutes, and is unable to cool itself down, the CDC warns. Symptoms of heat stroke can include confusion, slurred speech, loss of consciousness, profuse sweating and seizures.
