Stay safe and healthy during extreme heat, VA advises

The Department of Veterans Affairs has issued an important health advisory as extreme heat conditions continue to affect communities across the United States. First published in June 2025 and updated in July 2026, the guidance from VA's Public Health division and Office of Emergency Management emphasizes that temperatures above 90 degrees Fahrenheit lasting at least two days can lead to serious medical issues, medical emergencies, and even death. VA officials stress that while extreme heat poses real dangers, veterans can take concrete steps to prevent health problems and stay safe during severe summer weather.

Extreme heat events have become an increasingly significant public health concern, particularly for vulnerable populations including older adults and individuals with chronic health conditions. The VA's Public Health division works alongside the Office of Emergency Management to monitor environmental health threats and provide guidance to the veteran community. These advisories are part of VA's broader emergency preparedness efforts, which aim to help veterans understand and respond to various health and safety risks throughout the year. The current heat season guidance reflects the agency's recognition that many veterans face heightened risks during periods of extreme temperatures due to age, service-connected disabilities, or underlying medical conditions.

This advisory applies to all veterans nationwide, though the immediate risk varies depending on geographic location and current weather patterns. Veterans with certain service-connected conditions may face particular vulnerability during heat waves, including those with cardiovascular disease, respiratory conditions, or mobility limitations that make it difficult to access cooling or hydration. Older veterans and those taking certain medications that affect the body's ability to regulate temperature or maintain proper hydration should pay especially close attention to heat safety recommendations. Family members and caregivers of disabled veterans should also familiarize themselves with the warning signs of heat-related illness.

The VA defines extreme heat as temperatures exceeding 90 degrees Fahrenheit sustained for at least two consecutive days, though dangerous conditions can occur at lower temperatures depending on humidity levels and individual health factors. The advisory was first published on June 27, 2025, and received an update on July 2, 2026, indicating that VA continues to monitor and refresh this guidance as conditions warrant. Veterans experiencing heat-related medical emergencies should seek immediate care, and those in crisis can contact the Veterans Crisis Line for confidential support from qualified responders, many of whom are veterans themselves.

For disabled veterans, extreme heat presents challenges that extend beyond general discomfort. Many service-connected disabilities can complicate the body's natural cooling mechanisms or limit a veteran's ability to take protective action independently. Veterans with mobility impairments may struggle to access air-conditioned spaces, while those with cognitive conditions might not recognize early warning signs of heat exhaustion or heat stroke. Understanding these risks and planning ahead can make the difference between a safe summer and a medical emergency that could affect ongoing treatment plans or disability compensation claims.

Veterans should review VA's heat safety guidance and assess their personal risk factors in consultation with their VA healthcare providers. Those enrolled in VA healthcare can discuss heat-related concerns during regular appointments and ensure their care teams are aware of any conditions that might increase vulnerability. Veterans not currently enrolled in VA healthcare but eligible for services should consider enrollment, as access to regular medical care becomes even more critical during extreme weather events. Staying informed about local weather forecasts, maintaining adequate hydration, and having a plan to access cooling during heat waves are practical steps every veteran can take to protect their health and safety throughout the summer months.
