1. First of all, college students, as an important group in society, their safety awareness and self-help and mutual rescue ability are directly related to social stability and development. By popularizing first aid knowledge, we can improve college students' safety awareness and self-help and mutual rescue ability, so that they can take countermeasures quickly and correctly in case of emergency and reduce injuries and losses.

Secondly, colleges and universities are crowded places. In emergencies, such as fires and earthquakes, it is easy to cause casualties. College students with first aid knowledge and skills can be the first responders, help injured students in time, reduce the degree of injury and even save lives.

3. In addition, college students are in the active period of youth, so they have more opportunities to participate in various sports activities, and the risk of sports injuries increases accordingly. Popularizing first aid knowledge can help college students correctly handle sports injuries, such as sprains and fractures, and reduce the occurrence of secondary injuries.

Furthermore, popularizing first aid knowledge in colleges and universities is also helpful to cultivate students' sense of social responsibility and spirit of helping others. Facing the difficulties of others, college students with first aid skills can lend a helping hand, transmit positive energy and make contributions to building a harmonious campus and society.

Finally, from a global perspective, many developed countries have incorporated the knowledge of first aid into their regular teaching courses, which shows that they attach importance to first aid education. Colleges and universities in China should also learn from these experiences, take popularizing first aid knowledge as an important part of education, and improve the comprehensive quality of college students and their ability to deal with emergencies.
