EMSA Medical Heat Alert Issued for Sixth Time in 2026

EMSA Issues Sixth Medical Heat Alert of 2026 in Oklahoma City

EMSA issued its sixth Medical Heat Alert of 2026 Monday after paramedics responded to five suspected heat-related illness calls in the Oklahoma City area within a 24-hour period.

Three of those patients were transported to nearby hospitals for additional treatment, according to the Emergency Medical Services Authority.

The latest alert comes during an already demanding summer for paramedics. EMSA has transported 255 patients for heat-related illnesses in 2026, surpassing the number of heat-related transports recorded in both 2025 and 2024.

EMSA Issues Sixth Medical Heat Alert After Five Heat Calls

An EMSA Medical Heat Alert is triggered when paramedics respond to five or more suspected heat-related illness calls within a 24-hour period.

Monday's five calls met that threshold, prompting the sixth alert of the year for the Oklahoma City service area.

The alert remains in effect until temperatures or the number of heat-related emergency calls decrease significantly.

EMSA says residents should take the continued heat seriously, particularly people spending extended periods outdoors, older adults and those without reliable access to air conditioning.

The Oklahoma State Department of Health says heat-related illnesses and deaths are preventable and recommends staying hydrated, limiting strenuous outdoor activities during the hottest parts of the day and spending time in air-conditioned environments whenever possible.

Heat-Related Illness Transports Reach 255 in 2026

The number of patients requiring emergency transportation illustrates how significant this year's heat has been across the Oklahoma City area.

EMSA paramedics have transported 255 patients because of heat-related illnesses in 2026, already exceeding the totals recorded during the previous two years.

Heat illness can range from relatively mild symptoms to a life-threatening emergency.

The Oklahoma Department of Emergency Management says symptoms of heat exhaustion can include heavy sweating, dizziness, headache, nausea and weakness. Heat stroke is a medical emergency and can include confusion, very high body temperature, seizures or loss of consciousness. Anyone showing signs of heat stroke should receive immediate emergency medical attention.

Extreme heat can be particularly dangerous for older adults, young children, people with chronic health conditions, outdoor workers and people without access to air conditioning.

Oklahoma emergency officials also encourage residents to check regularly on family members, friends and neighbors who may be especially vulnerable during periods of prolonged heat.

EMSA Medical Heat Alert Prompts Safety Reminders

With the EMSA Medical Heat Alert in effect, residents are being encouraged to take precautions before spending significant time outside.

EMSA recommends drinking water and electrolyte-replacement beverages before and during prolonged outdoor activity, rather than waiting until thirst develops.

People working or exercising outside should wear lightweight, loose-fitting and light-colored clothing, take frequent breaks in shaded or air-conditioned locations and avoid excessive alcohol and caffeine, which can contribute to dehydration.

Anyone without air conditioning should consider spending time in a cooling center or public indoor location, such as a library, community center or shopping mall.

The Oklahoma Department of Emergency Management's heat safety guidance also recommends limiting outdoor activities to cooler parts of the day, drinking plenty of water and learning to recognize the warning signs of heat exhaustion and heat stroke.

People working outdoors are encouraged to work with a partner, carry a cell phone and watch one another for signs of heat illness.

With 255 heat-related patient transports already recorded this year, EMSA's sixth alert serves as another reminder that dangerous heat can become a medical emergency quickly, even as Oklahoma moves toward the end of summer.
