First aid is the immediate care given to someone who is injured or suddenly ill. It aims to preserve life, prevent the condition from worsening, and promote recovery. Basic first aid skills can help in emergencies, such as treating cuts, burns, or sprains, and can even save lives in critical situations like cardiac arrest or choking. Learning first aid is important for everyone, as accidents can happen anywhere, whether at home, school, or work. Knowing how to use a first aid kit and perform techniques like CPR or the Heimlich maneuver can make a significant difference in an emergency, providing comfort and support until professional help arrives.
