Extreme heat events, characterized by a series of days significantly hotter than average for a given time and place, pose a substantial public health risk. These conditions are responsible for more fatalities than any other weather event, a trend exacerbated by the ongoing climate crisis, which contributes to their increased frequency, severity, and duration.

Preparing for such events is crucial. Emergency supplies should include at least one gallon of drinking water per person per day, along with non-perishable food, essential medicines, sunscreen, wide-brimmed hats, backup batteries, and device chargers. A one-month supply of medication, secured in a child-proof container, and any necessary medical supplies or equipment are also recommended. Public safety officials advise assembling a “Go-Kit” with at least three days of portable supplies for evacuation, and a “Stay-at-Home Kit” containing at least two weeks of provisions for sheltering in place.

Maintaining a cool body temperature is paramount. Relying solely on electric fans is not sufficient when temperatures reach the high 90s. Individuals are encouraged to spend several hours daily in air-conditioned environments when possible. For those without access to air conditioning or in the event of a power outage, identifying a designated cool location such as a public library, shopping mall, or an official public cooling center is a critical step. In Hilton Head Island, public facilities often serve this purpose during severe weather advisories.

Hydration is another cornerstone of heat safety. An average person requires approximately three-quarters of a gallon of water daily, though individual needs fluctuate based on activity levels and environmental conditions. It is advisable to avoid sugary, caffeinated, and alcoholic beverages, which can contribute to dehydration. When engaging in activities that cause heavy sweating, combining water intake with snacks or a sports drink can help replenish essential salts and minerals.

During periods of extreme heat, limiting outdoor activity is strongly recommended. Any necessary outdoor work or errands should be scheduled for the cooler parts of the day, typically earlier in the morning or later in the evening. Wearing lightweight, loose-fitting clothing and taking cool showers or baths can also aid in maintaining a comfortable body temperature.

Certain populations face a heightened risk during extreme heat. This includes older adults, infants, young children, and pregnant women. Individuals with pre-existing medical conditions, outdoor workers, those with limited personal resources, and residents living in areas lacking green spaces are also particularly vulnerable. Awareness of these risk factors can guide targeted assistance and support within the Hilton Head Island community.

Recognizing the signs of heat-related illness is vital for timely intervention. Heat cramps, characterized by heavy sweating accompanied by muscle pain or spasms, should be treated by moving to a cool place and consuming water or a sports drink.

Heat exhaustion presents with more severe symptoms, including heavy sweating, cold, pale, and clammy skin, a fast but weak pulse, nausea or vomiting, muscle cramps, tiredness, weakness, dizziness, headache, or even passing out. Treatment involves moving the affected person to a cool location, loosening their clothing, and offering slow sips of water. Medical attention is necessary if vomiting occurs, symptoms persist for more than an hour or worsen, or if confusion develops.

The most severe form, heat stroke, is a medical emergency that can be fatal. Warning signs include a body temperature of 104°F or higher, hot, red, dry, or damp skin, a fast and strong pulse, headache, dizziness, nausea, confusion, or loss of consciousness. Immediate action is required: call 911 without delay, move the person to a cool place, and begin cooling their body with wet cloths, misting, fanning, or a cool bath. It is crucial not to give the person anything to drink.

### Why it matters in Hilton Head Island

As a popular resort destination and a growing community within Beaufort County, Hilton Head Island experiences significant summer heat and humidity. The guidance on extreme heat safety is particularly relevant for the island’s diverse population, which includes a substantial number of older adults and a vibrant tourism sector with many visitors unaccustomed to the Lowcountry’s summer climate. Novant Health Hilton Head Medical Center and other healthcare providers on the island are prepared to address heat-related emergencies, underscoring the importance of public awareness and proactive measures to prevent serious health outcomes. Adhering to these safety protocols helps ensure the well-being of both residents and visitors, mitigating the strain on local emergency services during peak summer months.
