When something unexpected happens, knowing how to recognize a concern, stay safe, get help and support another person can make a meaningful difference.
First aid is the immediate assistance provided when someone becomes ill or injured. Its purpose is not to turn a young person into a doctor. It is to help people recognize that something may be wrong, act safely, prevent further harm and connect the person with appropriate help.
The International Committee of the Red Cross describes first aid as essential assistance intended to preserve life, prevent further injury or illness, alleviate suffering and contribute to recovery.
This makes first aid both a health skill and a human responsibility: we look after ourselves, notice when others may need help, and understand when trained professionals should take over.
First aid begins before any technique. The first question is whether there is a problem, whether the situation is safe, and what kind of help is needed.
Notice signs that someone may be injured, unwell, distressed or in danger.
Stay calm and take an appropriate first step rather than rushing into an unsafe situation.
Protect yourself, the person who needs help and others nearby from additional danger.
First aid is often a bridge between an emergency and professional care.
Recovery includes continued care, communication, learning and emotional support.
Safe, appropriate actions that can help someone while further assistance is being arranged or while waiting for professional care.
Determining the cause or nature of a health problem requires appropriate clinical knowledge, assessment and, when needed, testing.
Healthcare professionals may provide assessment, treatment, monitoring, referral and ongoing care.
Preparedness reduces uncertainty. Families, schools and communities can think ahead about risks, communication, emergency supplies and how people will support one another.
Know how your household will communicate, where people will meet, who can help children and what to do if normal services are disrupted.

Reading about first aid is useful, but practical skills are best learned through appropriate instruction and practice.
Canadian Red Cross training →Prepared communities know their risks, communicate, support vulnerable people and work together before, during and after emergencies.
Explore community resilience →The Canadian Red Cross provides first-aid education, practical tips, educational resources and training opportunities. Its First Aid App provides access to first-aid information and can support learning and preparedness between training sessions.
The ICRC's 2025 publication presents first aid as essential assistance intended to preserve life, prevent further injury or illness, alleviate suffering and contribute to recovery.
In humanitarian settings, first aid is connected to dignity, safety, protection and the realities of responding when resources may be limited.
Explore the ICRC resource →The International Rescue Committee works in humanitarian crises to help people survive, recover and regain control of their futures.
Its work reminds us that emergency health is not only about an individual event. Conflict, disaster, displacement, poverty, disrupted services and limited access to care can all shape health outcomes.
Explore humanitarian health work →The World Health Organization and International Committee of the Red Cross developed Basic Emergency Care (BEC) as an open-access training programme for first-contact healthcare providers managing acute illness and injury, particularly where resources may be limited.
BEC uses a systematic approach to emergency assessment and management and addresses areas such as trauma, difficulty breathing, shock and altered mental status.
For GHE learners, the important lesson is not to reproduce clinical protocols. Instead, it is to understand how first aid connects to emergency care systems and why trained healthcare workers need structured approaches to serious illness and injury.
Children, older adults, people with disabilities, people with chronic health needs and people who rely on medications or medical equipment may have additional preparedness needs.
Age-appropriate preparedness can help children understand what to do, who to contact and how adults and emergency services can help.
A plan is more useful when people know where it is, understand their roles and revisit it as household circumstances change.
Families and communities become stronger when people consider accessibility, communication, social support and the needs of neighbours.

NextGenU provides free health-science education across public health, medicine, nursing and related fields. It offers an additional educational layer for learners who want to explore health systems, humanitarian response, public health and evidence beyond this introductory GHE module.
Emergency preparedness is not equally easy for everyone. Housing, income, transportation, disability access, language, digital access, social support, healthcare availability and community infrastructure can shape a person's ability to prepare and respond.
A Global Health Explorer therefore asks not only: “Are people prepared?” but also: “Do people have a fair opportunity to become prepared?”
Strengthening health knowledge, emergency response and access to appropriate care.
Recognizing that preparedness and access to care are shaped by social and structural conditions.
Building communities that can prepare, respond, adapt and recover from emergencies.
Understanding the importance of trusted institutions, emergency systems and protection during crises.
Choose one setting — your home, school, sports environment or neighbourhood — and investigate how prepared it is for an emergency.
What would help you stay calm in an emergency?
Who are the trusted adults or services you could contact?
What could your household or school do better?
How can preparedness become a community responsibility?
First aid begins with knowledge, grows through training, and becomes more powerful when families, schools, communities and health systems prepare together.
