Simple Strategies in Preventing & Treating Viral Infections
Thankfully the cold and flu season will soon be behind us. In northern Idaho it seems like so many people are getting sick with multiple complications. New strategies and old remedies really do work, but few people know about them or use them effectively.
Reducing the Viral Load
The virus invader attacks the body first through the nose and throat. Once inside the moist warm environment it multiplies exponentially. The first warning is a light irritating runny nose or scratchy throat.
While the first symptoms may be small, it’s imperative to act immediately to reduce the exponential viral replication! It takes some time for natural immunity to recognize the invader and initiate the response to destroy it.
Once immunity is activated white blood cells move into the nose and throat to attack the invaders. The area becomes red, swollen, edematous and painful. Mucus production increases to flush the virus out of the system. This process is an amazing creation from God to heal the body and the common symptoms of a cold.
Early Treatment with Xlear
Recent studies have shown some antiviral and antibacterial properties of the nasal spray Xlear. The main ingredient is a natural product: Xylitol. Emerging research shows promise by altering the salt concentration within the nose thus becoming more resistant to viruses and bacteria. The manufacturer states:
Using Xlear xylitol saline spray at the first sign of symptoms or after high‑risk exposures may help keep nasal passages moist, support mucus clearance, and potentially lower the number of germs in your nose, but it should be considered supportive care rather than actual medicine.
It’s recommended to be used twice a day, is inexpensive and available on Amazon.
Listerine Gargle
When encountering those first symptoms it’s important to destroy the virus that entered the throat. Listerine mouthwash is an antiseptic for the throat. Gargling with Listerine or a similar product 4 times a day helps to reduce viral replication.
Nasal Lavage
Few people perform nasal lavage, but this treatment is a major key for preventing sinus infections and highly recommended by ear nose and throat (ENT) physicians. The inflammation in the nose produces a great deal of watery mucus. The swelling and secretions often block the sinus passages and ultimately the mucus may become infected.
Nasal lavage is a method for rinsing the nose and sinuses with a saline solution which helps to flush the mucus out. It should be done at least twice a day. Individuals who suffer from frequent sinus infections should speak to a healthcare provider before using nasal lavage regarding the frequency of treatment.
The best approach is to insert warm water into the bottle, add the saline packet and shake it. Tilt the head facedown over the sink. Open the mouth and squirt the solution into one nostril and then the other until the solution is gone.
Discomfort and stuffiness are reduced when the mucus is flushed out. The bottle and solution may be purchased from most pharmacies.
Inhalers
As the virus irritates the back of the throat and airway some people may experience an annoying hacking cough with certain more virulent viruses. Individuals who have issues with coughing should speak with their healthcare provider about the benefits of having an inhaler on hand for more serious viral infections.
Most people use an inhaler incorrectly and don’t get the benefit from the prescribed medication. It’s vital to use an aerochamber or spacer for best results. Without it most of the medication ends up in the mouth and not in the lungs where needed.
Insert the inhaler into one end of the chamber and shake the device. Push the inhaler button and take a deep breath through the other opening. Hold it for 5 to 10 seconds, then take 5 small slow breaths in and out. Keep the mouth closed while the medication is moving deeper into the lungs and don’t talk for 5 minutes. Repeat the process for the second puff.
This technique allows the medication to move deeper into the lungs opening and relaxing the airways thereby reducing the cough.
Cool Mist Vaporizer
Using a cool mist vaporizer at night allows moisture to enter dry and irritated nasal passages, irritated throat and lungs.
Cepacol Extra Strength Sore Throat and Cough Lozenges with Benzocaine
An irritated throat can cause trauma to the voice box. Benzocaine causes a numbing sensation within the throat and helps soothe the irritated areas. Voice rest is a must!
Warm Tea with Honey
This treatment seems simple but is also very effective to soothe an irritated throat.
The Importance of Vitamin D
Vitamin D is needed for every immune cell to wage war against a virus, bacteria or cancer cell. Remember once used it needs replaced. Further complicating the situation, it takes 3 weeks from the intake of the D3 supplement to be converted into the Vitamin D hormone the immune system can use.
Another problem is that physicians disagree on what is considered an appropriate level. Complicating the issue is most lab values are often outdated. When research changes it may take years for those new values to be reflected in the lab result on a blood test report.
Few people in northern climates get enough Vitamin D from the sun. It’s imperative to get a Vitamin D level lab test. It helps the healthcare provider determine the best dose for the individual. Vitamin D3 and K2-M7 along with calcium promote bone strength and strengthen immunity.
Day Quil/Night Quil for High Blood Pressure
It’s best to let a virus run its course. A low-grade fever (<100.4 F) is a sign that the immune system is fired up doing its job. However, the symptoms can get annoying. Day Quil/NightQuil for High Blood Pressure helps reduce some of the discomfort. Seniors should consider beginning with half the dose. Its best to check with a healthcare provider before using this over-the-counter medication.
Healthy Lifestyles
A healthy diet rich in fresh fruits and vegetables, lean meats and dairy enhance immunity. Getting adequate sleep each night, physical activity and fresh air are vital.
Interestingly, Florence Nightingale (Godmother of Nursing) came from a wealthy family. During the Crimean War (1850’s) she found wounded soldiers dying from putrid hospital conditions. She opened the windows, changed the linens and dressings and literally brought sunshine and better food into their lives. The Lord used Florence and her nurses to heal the wounded. Simple things still help and apply to viral infections (colds), the flu and a host of abominable conditions of which people suffer.
When To See a Healthcare Provider
Dr. Jennifer Robinson described 6 situations when individuals should follow up with a healthcare provider.
- You have trouble breathing or have chest pain (seek immediate help).
- An adult with a temperature that lingers over 100.4 degrees F.
- You can’t keep anything down.
- Severe sore throat pain.
- Lingering cough.
- Lingering headache and congestion.
On A Personal Note
My goal is to post this blog on the first day of the month but I’m running behind. I was feeling overconfident that my last cold was 2 years ago. My prevention strategies were working! However, while caring for my young grandchildren with ear and sinus infections I contracted their bug.
While I took my own advice, it did linger longer than I expected. There were a few uncomfortable days, but it worked, and my prayers were answered. The Lord healed me without any complications.
If you have suggestions or tips of what has worked for you, please share them in the comments. Pray about better solutions to deal with your next viral infection and prepare for it now. Get the supplies you may need as described in this blog. Talk with your healthcare provider about strategies specific to your needs. May God bless you and heal you too.
O Lord my God, I cried to you for help, and you have healed me (Psalm 30:2).
I’m a Christian nurse who helps people navigate the murky waters of healthcare.
