Dr. Ahmed Every winter starts the same way, with sniffling and coughing, runny noses, and fever. As temperatures plunge and people huddle indoors, the common cold and the flu seem to lurk around every corner.
Although very common, these colds and flus can spread quickly and cause disruption in daily life activities. So, in winter everyone has their minds on:
- How to escape the flu?
- Is flu A or B worse?
- How long does a cold last?
- And do remedies like chicken noodle soup, “Italian penicillin,” vitamin water, or a hot toddy actually help?
Here we will discuss all these common winter questions together, offering a clear, practical guide to the causes, differences, treatments, and myths surrounding these familiar seasonal ailments.
How Can You Get the Flu?
The flu, or influenza, is an illness caused by influenza viruses. These viruses infect the respiratory tract.
You can catch the flu mainly by the respiratory droplets created when someone who is sick coughs, sneezes, speaks, or even breathes near you.
These droplets may land in your mouth, nose, or eyes. You can also become infected by touching surfaces like doorknobs, elevator buttons, or shared devices contaminated with the virus and then touching your face.
There are a few reasons the flu spreads so easily:
1. People are contagious before they know they’re sick
Most people start spreading the virus a day before the symptoms appear, and they remain contagious for almost a week
2. Influenza viruses survive well in cold, dry air
Winter and dry air lead to dry nasal passages, making it favorable for viruses to be stable in the air for a longer time.
3. Close indoor contact
Schools, offices, public transport, and holiday gatherings are ideal places for viral spreads.
Because of this, the flu circulates rapidly each year, especially in areas where people are in close quarters.
Is Flu A or B Worse?
Many people are surprised to learn there’s more than one type of flu. Of the many kinds of influenza viruses, types A and B are the most common to infect humans. Both can make you very sick, though there are differences.
Influenza A
- Infects both humans and animals
- Mutations occur very rapidly
- The cause of most flu outbreaks and pandemics
- Often associated with more severe seasons
Influenza B
- Infects only humans
- Mutations occur slowly
- Typically causes smaller outbreaks
- Tends to lead to milder seasons, although it can still be serious
Which is worse?
In general:
• Flu A is usually believed to be a more severe illness, causing widespread outbreaks.
• Flu B can still be intense, but often affects children more than adults.
That said, either type can cause high fever, body aches, fatigue, cough, and complications such as pneumonia, especially in old people, pregnant women, and people with a weak immune system.
How Long Does a Cold Last?
While colds and the flu share the same symptoms, they are different illnesses. A cold is usually caused by rhinoviruses, not influenza. Colds generally begin more gradually than the flu.
Typical cold timeline:
• Days 1–2: Sore throat, stuffy nose, sneezing
• Days 3–5: Peak symptoms—congestion, cough, mild fatigue
• Days 5–10: Symptoms gradually improve
Most colds last 7–10 days. Some cough or congestion may linger for up to two weeks, especially if the infection triggered inflammation in the airways.
What Does Yellow Phlegm Mean?
One of the very common concerns when having a cold or flu is noticing yellow or green phlegm. Although that might sound alarming, yellow phlegm does not necessarily mean you will need antibiotics.
When your immune system is fighting an infection, white blood cells called neutrophils race to the site. These cells have enzymes that can tint mucus a yellow or green color. This can be normal for some viral infections, such as:
- Colds
- The flu
- Respiratory viral infections
You should seek medical attention if you experience:
- Phlegm lasting more than 10–14 days
- High fever
- Shortness of breath
- Chest pain
- Symptoms are suddenly getting worse after improving
These could indicate a bacterial infection or other complications.
Flu Vaccine Side Effects: What to Expect
The flu vaccine is one of the most effective tools for reducing the severity and spread of influenza. Like other vaccines, it can have side effects, but they are almost always mild and temporary.
Common Side Effects
- Soreness, redness, or swelling at the injection site
- Mild fever
- Fatigue
- Headache
- Muscle aches
- Chills
These usually last 1–2 days and are signs that your immune system is responding.
Rare and Serious Side Effects
Severe allergic reactions are very rare. When they happen, it is usually within minutes to hours after vaccination.
Symptoms can include hives, difficulty breathing, or swelling of the face and throat. People with a history of severe allergy to flu vaccines or components should consult a healthcare professional before vaccination.
The flu vaccine has an excellent safety profile overall and greatly decreases the risk of serious disease, hospitalizations, and complications.
Do Traditional Remedies Like Chicken Noodle Soup and “Italian Penicillin” Help?
When people get sick, comfort food often becomes part of the healing process. Two popular remedies, chicken noodle soup and Italian penicillin sou,p have reputations for helping with colds and the flu.
Chicken Noodle Soup
This classic remedy is more than just comfort food. Many studies suggest chicken soup:
- Possesses natural anti-inflammatory properties
- Helps in thinning of mucus
- Provides hydration
- Improves the nasal air flow
The warm broth also soothes the throat and helps maintain hydration, which is essential when you’re sick.
Italian Penicillin Soup
Often referring to soups like Italian wedding soup, garlic-heavy broths, or pastina in broth, this “penicillin” nickname highlights how comforting and healing these soups feel.
Ingredients such as garlic, herbs, chicken broth, vegetables, and sometimes lemon may have:
- ild antimicrobial properties
- Immune-supportive nutrients
- Warming, soothing effects
While neither soup is an actual antibiotic, both provide hydration, electrolytes, warmth, and nutritional elements that genuinely help the body recover.
Vitamin Water: Helpful or Hype?
Vitamin water and similar fortified beverages are popular among people trying to boost immunity or stay hydrated during illness. But do they actually help?
Pros
- Provide hydration
- Contain added vitamins such as C and B-complex
- May feel more appealing than plain water when sick
Cons
- Many varieties contain added sugar, which isn’t ideal when you’re ill
- Vitamin levels may exceed daily needs without offering additional benefit
- Not a substitute for a well-rounded diet or actual treatment
Hydration is crucial, but water, electrolyte drinks, and low-sugar options are usually better choices.
The Truth About Hot Toddies
Hot toddies, a mix of hot water, whiskey, honey, and lemon, are a long-standing home remedy for colds and flu symptoms.
Here’s what helps and what doesn’t:
What Helps
• Warm liquids can soothe a sore throat and help clear sinuses
• Honey has natural antibacterial properties and coats the throat
• Lemon provides vitamin C and can cut through congestion
What Doesn’t Help
- Alcohol does not kill viruses
- Whiskey can interfere with the immune response
- Alcohol can dehydrate you, worsening symptoms
A non-alcoholic hot toddy provides all the beneficial effects of warmth, honey, and lemon without the downsides. If a traditional hot toddy is used, it should be consumed in moderation and never when taking certain medications.
What Actually Works When You’re Sick
With so many remedies, questions, and home traditions surrounding the flu and colds, it’s helpful to summarize what truly makes a difference.
- Get vaccinated for the flu each year
- Maintain good hygiene
- Stay home and rest when you are sick
- Drink plenty of fluids like water, tea, and broth to maintain hydration
- Use over-the-counter medications for fever and pain
- Use humidifiers to ease congestion and improve nasal air flow
Conclusion:
Colds and the flu are a fact of life for most of us at some point, but understanding how they’re transmitted, how long they usually last, and which treatments actually help toward managing symptoms and preventing complications.
Whether you’re comforting yourself with a bowl of chicken noodle soup or sipping on a zesty Italian penicillin recipe, or you just want to learn the difference between flu strains A and B, the information here helps arm you to care for yourself and those around you.
But (and this is absolutely not a license to stop taking Mucinex), the best way to recover is also traditional: get plenty of rest, stay hydrated, continue getting vaccinated, and be hygienic. Take care of your body, and it will do the heavy lifting of healing naturally.
