Mark Buller, a research physiologist with the Thermal and Mountain Division of the <a href=\"https:\/\/usariem.health.mil\/index.cfm\/media\/news\/article\/2023\/USARIEM_data_scientist_receives_FLC_excellence_in_technology_transfer_award\" target=\"_blank\">U.S. Army Research Institute of Environmental Medicine<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Buller shared recent developments and updates for the device\u2019s use among soldiers and Marines at the Fort Moore, Georgia\u2019s annual HEAT Forum on Wednesday.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The system includes a chest strap sensor, smartphone application and algorithms. Buller and his team began work collecting data and monitoring troop\u2019s heart rate, skin temperature and other measures in 2019, but was put on hold during the COVID-19 pandemic in 2020.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since then, it has been used to gather data at events such as the <a href=\"https:\/\/www.armytimes.com\/news\/your-army\/2018\/09\/11\/the-army-is-studying-ranger-hopefuls-to-learn-more-about-heat-stroke\/\" target=\"_blank\">75th Ranger Regiment\u2019s Ranger Assessment and Selection Program<\/a>, Marine Corps Recruit Depot Parris Island, South recruit training, during ruck marches and runs during infantry basic training at Fort Moore and on the 12-mile ruck, runs and land navigation at the 169th Engineers Sapper Leader Course at Fort Leonard Wood, Missouri.<\/p>\n\n\n\t<aside class=\"smg-interstitial-link wp-block-smg-interstitial-link\">\n\t\t<a href=\"https:\/\/one.sightlinemg.com\/armytimes\/news\/your-army\/2018\/09\/11\/the-army-is-studying-ranger-hopefuls-to-learn-more-about-heat-stroke\/\" class=\"smg-interstitial-link__inner\">\n\t\t\t\t\t\t\t<div class=\"smg-interstitial-link__media\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"199\" src=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/icebath.jpg.jpg?w=300\" class=\"smg-interstitial-link__image wp-post-image\" alt=\"\" \/>\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"smg-interstitial-link__content\">\n\t\t\t\t<span class=\"smg-interstitial-link__kicker\">Related<\/span>\n\t\t\t\t<h3 class=\"smg-interstitial-link__title\">The Army is studying Ranger hopefuls to learn more about heat stroke<\/h3>\n\t\t\t\t\t\t\t\t\t<p class=\"smg-interstitial-link__excerpt\">The Army is measuring body temperature and heart rate as soldiers train, to see if they can predict heat casualties.<\/p>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/a>\n\t<\/aside>\n\t\n\n\n<p class=\"wp-block-paragraph\">Slightly more than 10,000 of the users were in basic training or infantry units, the other 4,000 were in special operations units.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe think we\u2019re at an end point where we can provide you a tool to help manage risk of heat illness in an active way,\u201d Buller said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Such a device will become more necessary if preliminary data from another Army research regarding temperatures and training days proves accurate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Maj. Erik Patton, who is currently studying warming trends at Army basic training installations through a program at Duke University, shared data at the forum that he\u2019s gathered on potential temperature increases at those locations in the coming decades.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By mid-century half of the training days at those posts will have minimum temperatures above the category I heat threshold of 78 to 82 F.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">His data also indicates a 300% increase of days at the red flag warning, or 88 F. That condition, short of the more severe black flag conditions, limits strenuous work for those not acclimated to six hours or less per day, according to <a href=\"https:\/\/home.army.mil\/wood\/application\/files\/8416\/2765\/1794\/Heat_Illness_Pocket_Guide.pdf#:~:text=High%20heat%20category%2C%20especially%20several%20days%20in,ambient%20temperature%20is%20over%2075%C2%BA%20Fahrenheit%20(F)).\" target=\"_blank\">Army regulations<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"6048\" height=\"4024\" src=\"\/wp-content\/uploads\/2026\/08\/HIPS.jpg.jpg\" alt=\"\" class=\"wp-image-88751\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/HIPS.jpg.jpg 6048w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/HIPS.jpg.jpg?resize=300,200 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/HIPS.jpg.jpg?resize=768,511 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/HIPS.jpg.jpg?resize=1024,681 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/HIPS.jpg.jpg?resize=1536,1022 1536w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/HIPS.jpg.jpg?resize=2048,1363 2048w\" sizes=\"auto, (max-width: 6048px) 100vw, 6048px\" \/><figcaption class=\"wp-element-caption\">Marine Sgt.

(Maddi Langweil\/Army)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Buller\u2019s team has sampled data from 14,000 troops since 2018. The <a href=\"https:\/\/www.dvidshub.net\/news\/434848\/mcrd-parris-island-heart-monitor-testing\" target=\"_blank\">Marine Corps<\/a> has used the system since 2021 to monitor heat illness symptoms among recruits at Parris Island during the Crucible, a three-day field training event at the end of recruit training.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 2023, Marine Lt. Gen. Kevin Iiams, requested procuring the HIPS device for use across Marine Corps Training, Buller said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cOur system has enabled us to alert to a heat illness before it happens and be able to take action before somebody falls over and has a severe heat injury,\u201d Buller said in an <a href=\"https:\/\/www.dvidshub.net\/news\/464999\/life-saving-technology-may-help-prevent-deadly-heat-injuries-troops-future\" target=\"_blank\">Army release<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The smartphone application part of the system allows users to monitor as many as 500 individuals and spot when a user\u2019s vital signs are indicating a potential heat illness coming on, Buller said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cOn the app, we can see the changing heart rates and other variables,\u201d said Emma Atkinson, a USARIEM Biomedical Researcher. \u201cThe system is programed to sense when someone is approaching higher than appropriate heat exposure levels. We will see green, yellow and red colors on the screen indicating how our Service Members are doing.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Through their research, Buller also said that they\u2019ve noticed a correlation in a user\u2019s gait that helps predict the onset of heat illness. When users begin to \u201cwobble,\u201d that\u2019s often a sign that they\u2019re about to have a heat-related incident.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That\u2019s only applicable in events where there is a regular gait to measure, such as ruck marches or runs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Researchers have been able to identify indicators and predict an approaching heat illness incident between 3.5 to 10 minutes before the incident occurred in some of the studies, Buller said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using heart rate and skin temperature, researchers have been able to create algorithms to estimate core temperatures, a key indicator of potential heat illness.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have measured more than 14,000 soldiers and Marines in recent years.<\/p>\n","protected":false},"author":7,"featured_media":88748,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_meta-robots-noindex":"","_yoast_wpseo_meta-robots-nofollow":"","_yoast_wpseo_canonical":"","_acf":"","_yoast_wpseo_primary_category":69,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","_smg_distribution_targets":[]},"categories":[12,69],"tags":[],"coauthors":[3396],"class_list":["post-43827","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","category-your-marine-corps"],"acf":{"subheadline":"","legacy_arc_id":"MEMEKGBPPFFNJEO4TXKG6HWA6Q","arc_canonical_url":"\/news\/your-army\/2024\/03\/01\/wearable-device-helps-predict-heat-illness-during-intense-training\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"","redirect_url":"","disable_inline_ads":false,"native_logo_pretext":"Presented By:"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v28.1) -
