Get Set for a Healthy Winter
Here, experts from the federal Food and Drug Administration (FDA) share tips on how you can get through the cold-weather season while doing what you need to avoid colds and flu.
Although contagious viruses are active year-round, we’re most vulnerable to them in fall and winter. That’s because, in large part, we spend more time indoors with other people when the weather gets cold.
Fortunately, you can fight back with several FDA-approved medicines and vaccines.
Colds and Flu
Most respiratory bugs come and go within a few days, with no lasting effects. But some cause serious health problems. People who use tobacco or who are exposed to secondhand smoke are more prone to respiratory illnesses and more severe complications than nonsmokers.
Colds usually cause a stuffy or runny nose and sneezing. Other symptoms include coughing, a scratchy throat, and watery eyes. There is no vaccine against colds, which come on gradually and often spread through contact with infected mucus.
Flu comes on suddenly and lasts longer than colds. Flu symptoms include fever, headache, chills, dry cough, body aches, fatigue, and general misery. Like colds, flu can cause a stuffy or runny nose, sneezing, and watery eyes. Young children may also experience nausea and vomiting with flu. Flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. You also can get flu by touching a surface or object that has flu virus on it.
Flu season in the United States may begin as early as October and can last as late as May, and generally peaks between December and February. According to the Centers for Disease Control and Prevention (CDC):
ore than 200,000 people in the United States are hospitalized from flu-related complications each year, including 20,000 children younger than age 5.
Between 1976 and 2006, the estimated number of flu-related deaths every year ranged from about 3,000 to about 49,000.
In the 2014-15 season, there were about 40 million flu-associated illnesses, 19 million flu-associated medical visits, and 970,000 flu-associated hospitalizations—the highest estimate for a single flu season.
Get vaccinated against flu.
With rare exceptions, everyone ages 6 months and older should be vaccinated against flu. Flu vaccination, available as a shot or a nasal spray, can reduce flu illnesses, doctors’ visits, missed work and school, and prevent flu-related hospitalizations and deaths.
It’s ideal to be vaccinated by October, although vaccination into January and beyond can still offer protection. Annual vaccination is needed because flu viruses are constantly changing, flu vaccines may need to be updated, and because a person’s immune protection from the vaccine declines over time. Annual vaccination is especially important for people at high risk for developing serious complications from flu. These people include:
Children younger than 5 years, but especially those younger than 2.
People with certain chronic health conditions (such as asthma, diabetes, or heart and lung disease).
People 65 or older.
Vaccination is especially important for health care workers, as well as those who live with or care for people at high risk for serious flu-related complications, such as people older than 65 or with compromised immune systems. Because babies younger than 6 months are too young to get a flu vaccine, their mother should get a flu shot during her pregnancy to protect them throughout pregnancy and up to 6 months after birth. Additionally, all of the baby’s caregivers and close contacts should be vaccinated.
Although there was a less than ideal match between circulating flu strains and those included in the vaccine during last season, CDC estimates that the vaccines still provided about half the protection they did during the previous season. CDC also reports that this season’s vaccines better match circulating viruses.
Practice healthy habits.
Wash your hands often. Teach children to do the same. Both colds and flu can be passed through contaminated surfaces, including the hands. Wash hands with warm water and soap for 20 seconds.
Try to limit exposure to infected people. Keep infants away from crowds for the first few months of life.
Eat a balanced diet.
Get enough sleep.
Do your best to keep stress in check.
What to Do if You’re Already Sick
Usually, colds have to run their course. Gargling with salt water may relieve a sore throat. And a cool-mist humidifier may help relieve stuffy noses.
Here are other steps to consider:
Call your health care professional. Start the treatment early.
Limit your exposure to other people. Cover your mouth with a tissue when you cough or sneeze.
Stay hydrated and rested. Avoid alcohol and caffeinated products, which may dehydrate you.
Talk to your health care professional to find out what will work best for you.
In addition to over-the-counter (OTC) medicines, there are FDA-approved prescription medications for treating flu. Cold and flu complications may include bacterial infections (e.g., bronchitis, sinusitis, ear infections, and pneumonia) that could require antibiotics.
Tips for Taking OTC Products
Read medicine labels carefully and follow the directions. People with certain health conditions, such as high blood pressure and diabetes, should check with a health care professional or pharmacist before taking a new cough and cold medicine.
Choose OTC medicines appropriate for your symptoms.
Nasal decongestants unclog a stuffy nose.
Cough suppressants quiet coughs.
Expectorants loosen mucus.
Antihistamines help stop a runny nose and sneezing.
Pain relievers can ease fever, headaches, and minor aches.
Check the medicine’s side effects. Medications can cause drowsiness and interact with food, alcohol, dietary supplements, and each other. It’s best to tell your health care professional and pharmacist about every medical product and supplement you are taking.
Check with a health care professional before giving medicine to children.
See a health care professional if you aren’t getting any better. With children, be alert for high fevers and for abnormal behavior such as unusual drowsiness, refusal to eat, crying a lot, holding the ears or stomach, and wheezing.
Signs of trouble for all people can include:
A cough that disrupts sleep.
A fever that won’t respond to treatment.
Increased shortness of breath.
Face pain caused by a sinus infection.
High fever, chest pain, or a difference in the mucus you’re producing, after feeling better for a short time.
