The heat wave is affecting residents across the Seattle area, particularly those who rely on air conditioning to maintain safe indoor temperatures. Vulnerable groups, such as the elderly, young children, and individuals with pre-existing health conditions, are at higher risk of heat-related illnesses. Prolonged exposure to high temperatures can lead to dehydration, heat exhaustion, or even heat stroke if precautions are not taken. The strain on cooling systems may also lead to increased energy consumption and potential equipment failures.
