Over-the-counter cold remedies can be helpful, but they must be carefully considered before use. They contain drugs that can cause serious side effects, interact with other medications, and worsen certain health conditions. For example, decongestants can help ease a stuffy nose but also can increase blood pressure and heart rate. And cough suppressants can help someone stop coughing, but taking too much can cause dizziness, confusion, or even changes in mood or thinking.

The flu virus triggers bodywide aches and pain by causing inflammation. People can ease flu aches by staying hydrated; taking warm showers; and using over-the-counter anti-inflammatory drugs such as ibuprofen (Advil, Motrin) or naproxen (Aleve).

Scientists are trying to create a vaccine that would protect people against all different strains of the influenza (flu) virus. These vaccines are being designed to target parts of the flu virus that don’t change regularly and so are consistent across all strains. The perfect vaccine would also prevent symptoms (since current vaccines help prevent hospitalization and death, but not symptoms), and its effects would last for a lifetime. While such a vaccine is still many years away from reality, improved flu vaccines are expected in the meantime.

With influenza virus, a new vaccine must be developed each year to adapt to the virus’s changing structure.

A bird flu strain that began circulating in 2020 continues to evolve globally and locally within the United States. If you're wondering what this means, understanding the basics — what bird flu is, how it spreads, whether foods are safe, and prevention tips — can help.

Keeping hands clean is a simple way to protect against from colds and flu. Proper handwashing involves using plenty of soap, lukewarm water and taking at least 20 seconds to clean the back of hands, between the fingers, and around the nails.

Avoiding germs that cause respiratory and gastrointestinal illnesses is especially important during the winter months, when cases are on the rise. Learn which strategies keep you safe. 

Sometimes mucus secretions in the lungs can persist after someone starts to get better from a chest cold, flu, pneumonia, or COVID. To cope with the problem, experts recommend two approaches. One is doing exercises that clear the lungs, such as a series of breaths and coughs that dislodges mucus. The other approach is doing exercises that strengthen respiratory muscles. An example is diaphragmatic breathing, a type of deep breathing that relies on the diaphragm muscle located below the lungs.

Tonsil stones are small white or yellow deposits on the tonsils. They develop when bacteria, saliva, food particles, and debris from cells lining the mouth get trapped in tiny indentations on the tonsils. While usually harmless, they can cause bad breath and sore throats.
