You have several ways to help your immune system resist colds and flu.
By Julie Garden-Robinson, Food and Nutrition Specialist, NDSU Extension Service
Recently, I was on six flights during the course of five days, with about 250 people per flight. Every flight had several people who were sneezing or coughing.
So, I was exposed to at least 1,500 people all nestled in a pressurized tube breathing the same recycled air.
Now I wait to see if my immune system was able to fight germs efficiently during this cold and flu season.
On one flight, my neighbor was coughing and sneezing on me, in between snoring loudly. You can hold your breath only so long. I wedged myself up to the plane’s window. I had no exit, and I never have used a parachute, anyway.
I felt as though I was on one of those TV commercials surrounded by green fog emitted by sick people. Most of us have heard the reports about this year’s flu season that has resulted in numerous deaths.
According to the Centers for Disease Control and Prevention, people with the flu can spread the virus droplets 6 feet away through coughing and sneezing. The droplets can land in our noses or mouths, or be inhaled into our lungs.
You can spread illness a day before you have symptoms and about a week after you become sick. Sometimes people are infected and they don’t have the flu symptoms.
Now that I am home, I am waiting to see if my immune system was wearing its boxing gloves and fighting germs. I had a flu shot and now it was being tested.
Having a cold is different from having the flu. People with the flu may have a fever (often with chills), cough, sore throat, runny nose, body aches, headache and fatigue. Children with the flu also might have vomiting and diarrhea.
For some people, especially adults 65 and older, pregnant women and children under the age of 5, getting the flu can be life-threatening. People with diabetes, kidney disorders, lung diseases, asthma and several other chronic diseases also are at high risk for serious consequences. Pneumonia, bronchitis and sinus or ear infections might follow a bout with the flu.
No one enjoys feeling under the weather, so what can you do to help prevent colds and the flu? Try these tips to help your immune system resist colds and flu:
- Have a flu shot every year.
- Be sure to wash your hands regularly. Lather up for at least 20 seconds. Consider using an alcohol-based hand sanitizer when a sink is not nearby. The sanitizer should contain at least 60 percent alcohol. You can use a hand sanitizer if hand-washing facilities are not readily available, but be sure to use enough hand sanitizer and rub your hands until the alcohol evaporates.
- Stay home when you are sick to help prevent others from being exposed. Create a “sick room” in your house, and be sure to practice good hygiene, and wash dishware/glasses with hot, soapy water.
- Be sure to cover your coughs and sneezes. Use a tissue to “catch your sneeze” or you can sneeze or cough into your elbow instead of your hands. Toss the tissue so others do not have to dispose of it for you, and then wash your hands as a precaution.
- Avoid close contact with people who are ill.
- Stay home for at least 24 hours after a fever is gone.
- Stay well-nourished every day with a varied, nutritious diet.
- Get regular physical activity. Aim for 30 minutes per day on most days of the week.
- Get enough sleep.
