Colds are not just inconvenient; they are also the main reason why adults miss work and kids miss school. In fact, the average adult gets two to three colds per year, and children often get more than that.

Are there ways to prevent a cold before you even get symptoms? How can you stop a cold if you’re already having symptoms? And can you get online treatment for a cold?

Read on for the answers to these questions, as well as more information about common colds and how you may be able to prevent them.

Causes and Symptoms of a Cold

While colds are always caused by a virus, there are many different viruses that can cause a cold. Rhinoviruses are the most common, but other viruses that can lead to a cold include human parainfluenza viruses, respiratory syncytial virus, common human coronaviruses, adenovirus, and human metapneumovirus.

Cold symptoms include:

  • Runny nose
  • Sore throat
  • Sneezing
  • Coughing
  • Body aches
  • Headaches

What Are the Stages of a Cold?

Most of the time, there are three main stages of a cold.

Stage 1

Typically, a cold will start with a sore throat and other mild symptoms, including fatigue and a slightly stuffy or runny nose with clear mucus. Symptoms gradually get worse over the next few days.

Stage 2

In stage 2, symptoms increase and worsen. This stage usually starts within two to three days and is the worst part of the cold. Symptoms in stage 2 include:

  • Congestion
  • Runny nose
  • Sore throat
  • Sneezing
  • Mild aches
  • Cough
  • Tiredness
  • Fatigue

Stage 3

Within 7-10 days, most people start to feel better and symptoms start to improve. Some symptoms may persist for up to two weeks, including:

  • Cough
  • Stuffy nose
  • Runny nose

How to Prevent a Cold Before it Starts

Wouldn’t it be best to prevent a cold before it starts? Colds are quite contagious, so it can be hard to avoid catching one. However, there are a few cold prevention tips that may help:

  • Stay away from people who are sick
  • Wash your hands often with soap and water, for at least 20 seconds
  • Avoid touching your nose, eyes, and mouth before washing your hands
  • Boost your immune system by eating a healthy diet, getting plenty of sleep, and managing your stress levels

Best Ways to Stop a Cold at the First Sign

Since it’s not always possible to stop a cold before it starts, let’s talk about how to prevent a cold when you feel it coming. Once you feel symptoms, there’s no way to avoid getting a cold, and there is no cure. However, there are some ways you can lessen the severity and duration of your symptoms:

  • Drink lots of fluids, especially water
  • Get plenty of rest and sleep
  • Eat a healthy diet, including fruits, vegetables, fat-free or low-fat dairy, grains, healthy oils, and protein-rich foods
  • Eat honey
  • Manage your stress levels
  • Use a humidifier
  • Take supplements like vitamin C, vitamin D, echinacea, and zinc (note that studies have shown mixed results with these supplements and they may cause side effects)
  • Use over-the-counter medications like decongestants, pain relievers, cough syrup, and throat lozenges

Frequently Asked Questions

How Can I Boost My Immune System to Fight a Cold?

According to Harvard Health, “There are no scientifically proven direct links between lifestyle and enhanced immune function.” However, they do recommend these healthy living strategies:

  • Exercise regularly
  • Don’t smoke
  • Eat plenty of fruits and vegetables
  • Get plenty of sleep
  • Minimize stress
  • Drink alcohol in moderation, if at all
  • Wash your hands and cook meat thoroughly to avoid infections

What Is the Best Thing to Take at the First Sign of a Cold?

There is some evidence that if you take one or more of the following, it may make your cold shorter or less severe:

  • Zinc
  • Echinacea
  • Vitamin C

What Is the Fastest Home Remedy for a Cold?

Unfortunately, there is no way to cure a cold, and there are no fast home cold remedies. Your best bet is usually to take over the counter medications, get plenty of rest, and drink lots of fluids. 

How Can I Prevent Colds Naturally?

The best way to prevent colds naturally is to take good care of yourself. That includes practices such as:

  • Getting plenty of sleep
  • Eating a healthy diet
  • Drinking plenty of water
  • Managing your stress levels
  • Not smoking
  • Avoiding refined sugars and carbohydrates

Could it Be Strep Throat, COVID-19, or the Flu Rather than a Cold?

Many illnesses have similar symptoms to the common cold, so it can be hard to know just what you’re dealing with. Symptoms of strep throat include:

  • Swollen, tender lymph nodes in your neck
  • Fever
  • Coughing
  • Headache
  • Nausea and vomiting
  • Loss of appetite
  • Red spots on the roof of your mouth
  • Malaise

Symptoms of the flu can include:

  • Fever
  • Muscle aches
  • Headache
  • Cough
  • Stuffy or runny nose
  • Sore throat
  • Fatigue
  • Vomiting or diarrhea (more common in children)

COVID-19 symptoms include:

  • Shortness of breath or trouble breathing
  • Fever
  • Fatigue
  • Cough
  • Diarrhea
  • Nausea or vomiting
  • Runny or stuffy nose
  • New loss of smell or taste
  • Body or muscle aches
  • Sore throat
  • Headache

If your symptoms are severe, see a doctor. Keep in mind that antibiotics are not useful in treating a cold, the flu, or COVID-19.

Can I Get Cold Treatment Online?

Generally, colds can be treated at home without needing to talk to a doctor. If at-home treatment isn’t enough, you can get cold treatment online with a video or phone appointment from a licensed PlushCare doctor.

If your cold symptoms don’t clear up within 10 days, or if you think you might have something other than a cold, it’s time to talk to a doctor. You don’t need to go to the doctor’s office, though. Now, you can have an online doctor appointment.

With PlushCare, you can have a video or phone appointment with one of our trusted doctors. Your doctor can answer your questions and recommend home treatments. If your physician thinks you would benefit from a medication not available over the counter, they can electronically send a prescription to your local pharmacy.

Getting started with PlushCare is easy. Simply click here, or you can download the PlushCare mobile app for free. You could talk to a doctor as soon as today!
