Millions of residents across California are under significant heat stress, particularly in areas like Ventura, San Diego, and the San Fernando Valley. Vulnerable populations, including those without reliable air conditioning or access to water, face heightened risks of heat-related illnesses such as heat exhaustion and heat stroke. Coastal and mountain communities, which usually experience milder temperatures, are also affected, increasing the strain on local resources. Prolonged exposure to high temperatures can lead to health emergencies, especially for the elderly and those with pre-existing conditions.
