# Extreme Heat to Persist Across Mid-Atlantic and Southeast Through Weekend

A dangerous heat wave continues to grip large portions of the United States, with no immediate break in sight for millions of residents. While the Great Lakes region and parts of the Northeast may finally experience cooling temperatures over the weekend, the Mid-Atlantic and Southeast face prolonged exposure to dangerously high temperatures.

Heat-related illness poses serious health risks during extended hot spells. The human body struggles to regulate core temperature when external heat overwhelms its cooling mechanisms. Sweat evaporation becomes ineffective in high humidity, which characterizes much of the Southeast. Vulnerable populations face the greatest danger: older adults, people with chronic illnesses, those taking certain medications, and individuals experiencing homelessness all show elevated risk during heat waves.

Health authorities recommend specific protective actions during extreme heat. Stay indoors in air-conditioned spaces during peak heat hours, typically 10 a.m. to 4 p.m. Drink water consistently, not waiting until thirst develops. Avoid alcohol and caffeine, which promote dehydration. Check on neighbors, friends, and family members regularly, especially those living alone or without reliable cooling access.

Heat exhaustion symptoms include heavy sweating, weakness, dizziness, nausea, and headache. Heat stroke presents more severely: high body temperature above 103 degrees Fahrenheit, confusion, loss of consciousness, or absence of sweating despite extreme heat. Heat stroke requires emergency medical care. Call 911 immediately if someone shows these signs.

Public cooling centers offer refuge for those without air conditioning. Libraries, malls, and community centers provide free access during operating hours. Some municipalities activate emergency protocols during extreme heat events, expanding cooling center hours and availability.

The extended nature of this heat wave increases cumulative health burden. Each day of extreme heat stress compounds physiological strain. Recovery time
