Doctors recommend examining the colour, smell, and frequency of your snot to determine if you have allergies or an infection, amid COVID-19 concerns.

Have you ever wondered why your runny nose produces different colored mucus? Or whether that color means you’re more sick than someone with clear snot? The color of your snot may actually hold important clues about what’s going on inside your body. Doctors have been paying close attention to the shade of our mucus for years, and they now have a better understanding of what each color means. So the next time you reach for that tissue, take a closer look at what’s in it- it may just hold the key to understanding your health.


Spring allergy season is at its height and people are suffering from symptoms such as runny noses and scratchy throats. These symptoms can be confusing and difficult to differentiate between allergies, the common cold, or COVID-19. However, according to Dr. Rama Wahood, a family medicine physician with American Family Care, the color of a person’s snot could provide an answer. Wahood recommends examining the color, smell, and frequency of snot, stating that clear or white snot is related to allergies, whereas darker colors indicate a worsening infection. Green or yellow snot could present a mild infection and darker or smellier snot could indicate a worsening infection.

Allergists with the American Lung Association have attributed the increase in patients with allergies to climate change, which is impacting pollen counts across the country. In addition, air pollution and temperature changes are also affecting both young and old patients. Wahood advises that seasonal allergies could worsen over time and that patients should be cautious of underlying infections such as pneumonia.

Snot isn’t the only indicator that health experts suggest examining. Different kinds of coughs can also provide useful information. A whistling cough could indicate wheezing, which is usually associated with asthma or chronic obstructive pulmonary disease (COPD). A rattly cough could suggest bronchitis or allergies. It’s important to note that if a person feels hot and has a fever, it’s less likely to be allergies.

Several patients have contacted American Family Care with questions about their symptoms. These symptoms can present similarly, making it challenging to differentiate between allergies, infections, or COVID-19. As such, examining the color of snot, monitoring coughs, and being mindful of their surroundings are ways that patients can help determine what they’re suffering from.

In conclusion, the color of snot, different kinds of coughs, and a person’s overall health can provide helpful information for determining if a person’s symptoms are due to allergies or an infection. Patients should be cautious of the changing seasons and have a general understanding of the different symptoms that they could experience. If patients are concerned about their symptoms or have questions, they should contact a healthcare professional.


In conclusion, your snot can provide valuable clues about your health. As we have discussed, the color of your nasal discharge can indicate whether you have a viral or bacterial infection, allergies, or even a more serious condition. Knowing what color your snot is can help you make informed decisions about your health and when it’s time to see a doctor. Remember to pay attention to your body and seek medical attention if you have any concerns about your runny nose or nasal discharge.
