Psychological first aid is essential because it provides immediate support and intervention to individuals experiencing stress, trauma, or emotional distress. In times of crisis, having the ability to offer psychological first aid can help reduce the short- and long-term impact of trauma by stabilizing emotions, promoting a sense of safety, and fostering resilience. This training equips individuals with the skills to listen, offer practical assistance, and connect affected people with professional help if needed. Ultimately, psychological first aid helps to create a supportive environment that aids in the recovery process and enhances overall well-being.
