Smoke inhalation occurs when a person breathes in harmful smoke from burning materials, such as wood, plastics, or chemicals. This can happen during fires, whether in buildings, forests, or vehicles. The smoke contains toxic substances that can damage the lungs and other parts of the respiratory system. Symptoms of smoke inhalation may include coughing, difficulty breathing, and a sore throat. In severe cases, it can lead to serious health issues, such as carbon monoxide poisoning or lung damage. Immediate medical attention is often necessary to treat the effects of smoke inhalation and prevent long-term complications.
