A hotline, specifically an emergency hotline, is a dedicated phone service that provides immediate assistance in crisis situations. These hotlines are often operated by trained professionals who can offer support, guidance, and resources to individuals facing emergencies, such as mental health crises, domestic violence, or substance abuse issues. Emergency hotlines are typically available 24/7, ensuring that help is accessible at any time. They may be associated with organizations like National Suicide Prevention Lifeline or Crisis Text Line, which aim to connect individuals with the appropriate services and support networks to address their urgent needs.
