Human: What should I do to prevent myself from catching a cold? Assistant: 
To prevent yourself from catching a cold, it is important to practice good hygiene. Make sure you wash your hands often and avoid touching your face or eyes. Avoid people who are sick and cover your mouth and nose when coughing or sneezing. Get plenty of sleep and exercise regularly. If you have the flu, take over-the-counter medications such as ibuprofen to help reduce fever and pain.
