November is almost here. Which means, winter is coming!

However, if you are excited about those live concerts and picnics, you also need to remember to protect yourself from those Winter shenanigans!

Yes, we are talking about cough, congestion, runny nose, and fever. Symptoms like these often mean you’ve caught a cold. But sometimes, these symptoms worsen with time and can even lead to a sinus infection or a bronchial infection (bronchitis).

So, sinus infection vs cold – what’s the difference? Well, we have jotted down all those explanations in this very blog. Let’s explore till the end to know it all!

Signs of a Cold

The common cold is one of the most common diseases of the winter season! It affects millions of people every year. Common cold infections occur when viruses affect your nose, mouth, throat, and lungs.

If you catch a common cold, the symptoms usually are sneezing, coughing, sore throat, muscle aches, and fever. According to a Rhinologist, Dr. Troy Woodard, a common cold infection usually lasts for 7- 10 days. Moreover, the symptoms of a common cold usually improve on their own.

However, if you see that the symptoms are persisting and worsening even after 10 days, chances are that it is either a sinus or a bronchial infection. Which brings us to the next section.

Is it a Cold or a Sinus Infection – How Can You Tell?

More often than not, we cannot tell the difference between a common cold infection and a sinus infection. Why so?

That’s because the symptoms keep overlapping, which makes it even more difficult to tell the difference. But Dr. Troy Woodard of the Cleveland Clinic has shared an interesting way that can help you determine whether you have a common cold or whether it has worsened to a sinus infection.

So, according to the Rhinologist, the best way to tell the difference is to ask yourself these four questions-

• For how long have you been experiencing the symptoms?

As mentioned in the previous section, a common cold usually lasts for 7- 10 days maximum. However, if your symptoms persist even after that, it might signal a bacterial sinus infection.

• Are you feeling persistent pressure on your nasal passage?

A common cold might cause you to sneeze and block your nasal passage for some time. But if the lining of your nasal passage swells or gets irritated, and you feel constant pressure, understand that it is a sign of a sinus infection.

Not just that, but you can also feel sinus pressure on your face, and might even experience pain or sudden tenderness. If these are the symptoms you are experiencing, be sure that your common cold is not so common anymore!

• What is the color of your mucus?

Another test that can surefire tell the difference between a cold and a sinus infection is the color of your mucus.

Yes, it sounds totally yuck! But it is the one thing that can clearly reflect whether you have a common cold or if it is more than that. For instance, if the mucus discharge is clear, understand that you are suffering from a common cold. On the contrary, if the discharge has a pale yellowish or pale greenish tinge to it, be sure that it’s a sinus infection you are dealing with.

• Are you experiencing persistent bad breath?

Lastly, keep a track of your breath (yes, even with a blocked nose!). What happens is, sinus gunk drains into your throat and emits a foul smell. So, if you find yourself brushing your teeth too often, be sure that you have a sinus infection, and not just a common cold.

Bronchitis Symptoms and Treatment

Now that you know the difference between a common cold and sinus infection, let’s take a look at another winter shenanigan- bronchitis!

Bronchitis is a condition that affects the bronchial tubes of your lungs. The symptoms of this disease include chronic cough with mucus, tightness in the chest, wheezing, and excessive tiredness.

However, there are no surefire ways to determine a bronchitis condition apart from lab tests. So, you can only distinguish a common cold from bronchitis via chest X-rays, sputum culture, or any other pulmonary function tests.

Along with some basic self-care measures like taking a lot of rest and keeping yourself hydrated, you do need to consult a healthcare practitioner to treat bronchitis. And that is probably the only common thing that both sinus infections and bronchitis have!

How to Protect Myself From These Diseases?

Remember the saying, ‘Prevention is better than cure?’ Well, that is exactly what you need to do! Avoid anything that makes you susceptible to viruses or bacteria that may later cause viral or bacterial infections.

Here is a list of things that you can do to keep yourself protected-

• Drink lots and lots of water. Hydration can help you in ways that you cannot even imagine!
• Use humidifiers at home, especially during this transition period. You can also try bringing in snake plants to enhance the indoor AQI, as virus-affected air is the main culprit behind such diseases.
• Always wear your mask when you step outside the house.
• Eat a balanced and nutritious diet. This will help keep your immunity levels high.
• And finally, if you see that your symptoms are worsening after the first 10 days, do visit a medical professional and sign up for tests immediately.

Also, if you just have a cold, try to avoid antibiotics as much as possible. Why? Because-

• Antibiotics cannot cure any virus. You have to give it time to make your symptoms wear off naturally.
• Overusing antibiotics can increase your antibiotic resistance. This means if you catch some infections in the future, it will be much harder to treat!

So, that is the whole difference between a sinus infection, a cold, and bronchitis. Understanding this will ultimately help you take the necessary steps and follow the respective treatment protocols for a speedy recovery!

F.A.Qs

1. How do I know if I have sinusitis or bronchitis?

Sinusitis, or a sinus infection, affects the upper respiratory tract. It causes symptoms like facial pressure or pain around the eyes, forehead, and cheeks. It also causes thick nasal discharge and post-nasal drip.

Bronchitis affects the bronchial tubes in the lungs. The symptoms are a persistent cough, along with mucus, chest discomfort, wheezing, and shortness of breath.

2. Can a sinus cold turn into bronchitis?

Yes, a sinus infection or cold can progress into bronchitis. That’s because your respiratory system is a connected pathway. Infected mucus from the sinuses can drain down the back of your throat (post-nasal drip) and irritate the bronchial tubes. This can lead to inflammation and the development of acute bronchitis.

3. What vitamin deficiency causes sinus problems?

A deficiency in Vitamin D leads to chronic sinus problems, such as chronic rhinosinusitis and nasal polyps. Vitamin D is crucial for immune function and helps to regulate inflammation, and low levels may weaken the body’s defenses.

4. What are 5 symptoms of bronchitis?

Five common symptoms of acute bronchitis are-

• Persistent cough, along with mucus that can be clear, yellow, or green
• Discomfort or tightness in the chest
• Shortness of breath
• Fatigue
• Soreness
