Stay Safe During Extreme Heat This Summer June 18, 2026 Summer is almost here, bringing backyard barbecues, beach days, camping trips and time outdoors. But rising temperatures can also pose serious health risks for people of all ages, especially during periods of extreme heat. According to the Centers for Disease Control and Prevention (CDC), extreme heat is one of the leading causes of weather-related deaths in the United States, and the number of heat-related deaths has been increasing in recent years. “Heat-related illnesses can develop quickly and become deadly without proper precautions,” said Alicia Bublitz, social determinants of health program manager for IHN-CCO. “We want people to have a plan before extreme heat arrives. Whether it’s identifying a nearby cooling center, checking on neighbors or understanding your own health risks, preparation can make a critical difference.” Who Is Most at Risk While extreme heat can affect anyone, some people are more vulnerable than others, including: Older adults and young children People with chronic health conditions such as heart disease, diabetes or respiratory illness Outdoor workers and those who spend extended time in the heat People without reliable access to air conditioning Individuals experiencing homelessness or housing instability People experiencing homelessness face especially high risks due to limited access to water, shade and cool indoor spaces. More broadly, nearly 1 in 4 people in the United States are considered socially vulnerable to extreme heat, due to factors like housing, transportation and income. The impact of extreme heat is not just theoretical. During Oregon’s 2021 heat dome, more than 100 people died from heat-related causes, highlighting how quickly dangerous conditions can escalate. Recognizing Heat-Related Illness Heat-related illnesses happen when the body cannot cool itself effectively. Symptoms can range from mild to life-threatening and may include: Heavy sweating or, in severe cases, lack of sweating Dizziness or fainting Headache Nausea or vomiting Rapid pulse Confusion or altered mental state Without prompt attention, heat exhaustion can progress to heat stroke, a medical emergency that can cause organ damage or death. Staying Safe in the Heat The good news is that heat-related illness is largely preventable with a few simple precautions: Stay cool: Spend time in air-conditioned spaces whenever possible Hydrate regularly: Drink water frequently, even if you don’t feel thirsty Limit outdoor activity during the hottest parts of the day Wear lightweight, light-colored clothing Check on others, including neighbors, older adults and those living alone Access to air conditioning is the most effective way to reduce the risk of heat-related illness. Even a few hours in a cool environment can make a difference. Plan Ahead, Stay Safe Extreme heat events are becoming more frequent and intense, making it increasingly important to plan ahead. Knowing where to go, how to stay cool and when to seek help can protect your health and the well-being of those around you. “Simple steps like staying hydrated, finding a cool place and checking on others can save lives,” Bublitz said. “We all have a role to play in keeping our community safe during extreme heat.”
