What is a recommended preventative measure for upper respiratory infections?

• A. Increased consumption of dairy
• B. Frequent handwashing
• C. Daily exposure to cold weather
• D. Avoidance of all exercise

Answer: (B)

Frequent handwashing is widely recognized as one of the most effective preventative measures against upper respiratory infections. The practice of regularly washing hands with soap and water helps eliminate pathogens that can be transmitted through surface contact or by touching the face. Given that viruses and bacteria can survive on surfaces for varying amounts of time, handwashing significantly reduces the chances of infection by removing these germs before they have the opportunity to enter the body. This simple yet powerful hygiene practice is endorsed by health organizations as a crucial step in preventing the spread of respiratory infections, particularly in communal environments where people are in close proximity to one another.
