First-aid myths may do more harm than good, says the University of Rochester Medical Center.
The school mentions these examples of first-aid folklore, and what to do instead:
- Putting hot water on frozen skin can cause serious damage. Slowly thaw skin with warm water instead.
- Rubbing alcohol does not bring down a fever. Use ibuprofen or acetaminophen instead.
- Putting coffee grounds on a cut to stop bleeding can cause infection. Apply pressure with sterile gauze instead.
- Rubbing butter on a burn can actually keep the heat in. Run cool water over the area to ease pain instead.
- Using ipecac syrup to induce vomiting can be dangerous. Call poison control immediately instead.
