Preventing Flu with Red Light Therapy: Myth or Reality?

Overview

For many, the change of seasons brings a unique anticipation—not only for the changing weather but also for battling colds and flu. Red light therapy is a cutting-edge treatment that has been discovered actually to boost the immune system. In this article, you are going to learn how red light therapy just might be your secret weapon during flu season in a very real way: how to maintain a high-functioning immune system so that you can battle through without a winter bog-down of illness dragging you down.

What’s Red Light Therapy?

Red light therapy is also known by the name of photobiomodulation or low-level light therapy. It is an easily available and non-invasive treatment technique to activate the body towards recovery and overall health. The therapy works with the two following light types and their corresponding wavelengths:

• Red light: Part of the visible spectrum, having wavelengths between 630-700 nanometers (nm).
• Near-infrared light: Enters the category of invisible to the naked eye, where their range is measured from 700 to 850 nm.

These waves can get to the skin at different depths, where they incite desirable cellular responses. Shorter wavelengths of light are seen in red light; hence red light is used in treatments for rejuvenating the skin and in wound healing. Deeper tissues correspond to longer wavelength light, which, therefore, will be useful in treating issues like chronic inflammation and joint pain.

The science behind red light therapy has to do with its interaction with the mitochondria, the powerhouses in your cells. Irradiating the mitochondria with this wavelength of light encourages them to make more ATP, the basic energy unit made by all living organisms. Increased cellular energy has been theorized to positively influence cell performance, accelerate repair, increase regeneration, and ultimately improve health in general.

How Red Light Therapy Strengthens Your Immune Defense

In relation to immune function, red light therapy can do several things that help reinforce your body’s natural defence in different respects. The energy boost will allow immune system cells to work better, which will facilitate their functioning in the identification and neutralization of pathogens. Red light treatment would stimulate and, therefore, increase the activity of mitochondria to enhance ATP production.

How Red Light Therapy Strengthens Your Immune Defense
• Improved Circulation: Red light therapy promotes the production of nitric oxide, a molecule that aids the widening of blood vessels. This improved circulation boosts the delivery of oxygen and nutrients to cells while facilitating the removal of waste products. Better circulation allows immune cells to travel easily throughout the human body to fight infections.
• Support for the Lymphatic System: The lymphatic system is vital for immune functions because it filters out bad substances and produces immune cells. Red light therapy improves lymphatic drainage, possibly making this system more efficient at waste elimination and supporting immune responses.
• Stem Cell Activation: Studies confirm that red light can activate and revitalize stem cells. These versatile cells can renew or multiply into many kinds of cells, including immune ones, enhancing the body’s defense against infections.
• Production of Melatonin: The production of melatonin—essential for the regulation of wake-sleep cycles—is significantly increased by exposure to red light, especially at night. Quality sleep is closely related to better immunity.
• Inflammation Reduction: Chronic inflammation often subdues immune function. Red light has been proven to be very anti-inflammatory, which is one of the ways it can balance and enhance immune function.
• Modulation of Cytokines: Cytokines are signaling molecules that coordinate immune responses. Red light therapy can optimize immune responses to infectious pathogens through the modulation of cytokines.

Combating Cold and Flu with Red Light Therapy

Common symptoms of colds and flu are targeted by red light therapy.

• Sore Throat and Cough: Pass the red light over your neck, preferably focusing on the carotid artery, for 10-20 minutes. This will help decrease inflammation and its associated pain in the throat, with a possible stimulation of local immune reactions.
• Nasal Congestion: Pass the light over your face, mainly localized over the nose, for 10-15 minutes. In this way, the infection in the nose is reduced, thus improving breathing, and the virus clearance might be faster.
• Headaches: Apply the light to your forehead for 10-20 minutes. It combats tension and may eliminate some inflammation that initiates sinus-related headaches.
• Muscle and Joint Pains: Apply the device to the areas of pain for 10-20 minutes. Red light therapy pretty much dissipates many of the body aches characteristic of flu because it has anti-inflammatory effects.
• General Support of the Immune System: Using red light therapy every day can promote the immune system even without targeting any symptoms in particular. During the flu season, it is recommended to have a full-body treatment every day for 10-20 minutes.

It is worth mentioning that consistency comes first in line when aiming for the best available results. The majority of users notice and feel the improvements within the first few sessions, but using it regularly during the whole flu season is the best protection and relief therapy.

Is Red Light Therapy Safe?

The high safety profile is one of the critical characteristics that make red light therapy so attractive. It is

• Non-invasive: It uses none of the incisions or injections, which makes it very easy to get.
• Chemical-free: It does not introduce any drugs or substances into the body.
• Non-thermal: Since no heat is produced on the outside, most risks of burn or thermal injuries are eliminated.
• Free from UV radiation: Unlike many light therapies, red light does not include any ultraviolet rays that can be harmful to the body.

Numerous safety studies on red light therapy have been conducted, with no/mostly minor side effects when treatment is appropriately administered. Then again, like any other treatment, guidelines should be adhered to:

• Limit average daily treatment time to no more than 20 minutes per area.
• Wear eye protection, especially with higher-power systems.
• Talk to a healthcare provider before starting red light therapy if you have any pre-existing medical conditions or take photosensitizing medications.
• It’s generally safe for all skin types, but people with sensitive skin should start with shorter sessions and increase the duration gradually.
