How to Prevent the Flu: Tips From a Doctor

The flu is a contagious respiratory illness caused by influenza viruses. While some people experience only mild symptoms, severe cases can lead to pneumonia and further respiratory problems. Here are some tips from a doctor to help you prevent the flu:

1. Get vaccinated. The flu vaccine is essential for preventing the flu. It's recommended annually, ideally before flu season begins in your area.

2. Practice good hygiene. This means washing your hands frequently with soap and water, covering your mouth and nose when coughing or sneezing, and avoiding contact with people who are sick.

3. Stay home if you're sick. If you develop flu-like symptoms, stay home from work or school to prevent spreading the virus to others.

4. Avoid large crowds. During flu season, try to avoid large crowds and gatherings as much as possible. If you must be in a crowded space, wear a face mask and keep your distance from others.

5. Strengthen your immune system. Eat a healthy diet, exercise regularly, and get enough sleep to support your immune system and improve your overall health.

6. Practice good humidifier/dehumidifier habits. Use a humidifier or dehumidifier to keep your home's humidity levels in a comfortable range. Ideal indoor relative humidity is between 30-45%. Dry air can dry out your nose and throat, making you more susceptible to infection.

7. Consider using antiviral medication. If you are prescribed antiviral medication, it's important to take it as directed to help lessen the symptoms of the flu and reduce the risk of complications.

8. Know when to seek medical help. If you experience severe flu symptoms, such as difficulty breathing, chest pain or pressure, or sudden dizziness, seek medical attention immediately.
