Leaders also must develop standard operating procedures for training and operational activities conducted in hot and cold environments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Required training includes work-rest cycles, heat flag warning systems, the Wet Bulb Globe Temperature (WBGT) index and the wind chill index. The guidance also stresses the importance of trained medical personnel in evaluating and treating Marines who suffer heat or cold injuries.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to requiring medical personnel assigned to Marine units to maintain rapid response plans and designated cooling or warming areas, the guidance notes that personnel exposed to excessive heat stress may require evaluation by a qualified health care provider to determine whether they have suffered a heat-related injury.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The guidance places particular emphasis on using the <a href=\"https:\/\/www.weather.gov\/tsa\/wbgt\" target=\"_blank\" rel=\"\">WBGT index<\/a> to assess environmental heat stress. Unlike the standard heat index, which measures only temperature and humidity, the WBGT factors in direct sunlight, wind speed, sun angle and cloud cover, providing a more complete picture of conditions that can contribute to heat illness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, the guidance has reporting requirements in that the unit safety representative must enter all confirmed heat or cold injuries into the Risk Management System. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The updated guidance comes as weather-related injuries continue to affect all branches of service. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to a recent <a href=\"https:\/\/www.health.mil\/Reference-Center\/Reports\/2026\/05\/01\/MSMR-Vol-33-No-5-May-2026\" target=\"_blank\" rel=\"\">report<\/a> by the Military Health System, 2,751 servicemen and women experienced heat-related injuries \u2014 heat exhaustion and heat stroke \u2014 in 2025 with the Marines reporting 641 of them. However, the data also shows that the total number of cases for the Marines dropped from 655 the year before. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As for cold weather injuries, the service <a href=\"https:\/\/ph.health.mil\/periodicals\/ppub-cold-injury-report-mar2026.pdf\" target=\"_blank\" rel=\"\">reported<\/a> 107 cases, likewise the second-highest total behind the Army. Those included 40 cases of non-freezing peripheral injury, commonly known as trench foot, 49 cases of freezing peripheral injury, or frostbite, and 18 cases of hypothermia.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to <a href=\"https:\/\/taskandpurpose.com\/news\/marines-hot-cold-injury-guidance\/\" target=\"_blank\" rel=\"\">Task &amp; Purpose<\/a>, which first reported on the message, this is the first update to the service\u2019s heat and cold injury prevention guidelines in 11 years. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The guidelines require leadership to develop response plans and report cases, so prepare to drink more water, Marines. <\/p>\n","protected":false},"author":7,"featured_media":49804,"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":{"2":{"categories":["your-military","news"],"primary_category":"your-military"}}},"categories":[101,12,25,69],"tags":[],"coauthors":[3388],"class_list":["post-35622","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-daily-news-roundup","category-news","category-newsletters","category-your-marine-corps"],"acf":{"subheadline":"","legacy_arc_id":"5ZLYR37ZSNCSFDOQZZJZPUC7QA","arc_canonical_url":"\/news\/your-marine-corps\/2026\/07\/22\/marines-release-updated-heat-cold-injury-safety-guidance\/","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) -
