How Can Red Light Help with Nasal and Ear Infections and against Bacteria?

By SWA

Red light therapy (RLT) has shown promising results in alleviating symptoms of nasal and ear infections. Research indicates that all rhinitis symptoms, including nasal congestion, significantly improve after a single red light rhinophototherapy (RLRPT) treatment. Additionally, red light therapy can relieve pain associated with middle ear infections. The duration and frequency of red light exposure for ear pain depend on the severity of the symptoms. It is recommended to expose the ear to the red light for a maximum of ten minutes at a minimum distance of 50 centimeters to avoid burns.

Rhinophototherapy for Rhinitis

Rhinophototherapy has been effectively used to treat both allergic rhinitis (AR) and chronic rhinosinusitis [1, 2]. Three different devices have been developed for this therapy, one of which emits visible red light at a wavelength of 660 nm, known as red light rhinophototherapy (RLRPT).

Preventing and Treating Cold Sores

Red light therapy may also help in preventing and treating recurrent cold sores, which are caused by the herpes simplex virus. The therapeutic effects of red light in this context are attributed to its ability to reduce viral load and promote healing.

Mechanism of Action on Bacteria

Red light kills bacteria via photodynamic action, a process where light-sensitive compounds react with light to produce reactive oxygen species that damage bacterial cells. While red light can be effective, intense blue light, particularly at 415 nm, has been found to be more effective in killing bacteria.

Pain Relief and Anti-Inflammatory Effects

Red light therapy may be beneficial for relieving various types of pain, especially those due to inflammation (irritation and swelling of body tissues). Its anti-inflammatory properties help reduce pain and promote tissue repair.

Can I use red light therapy while on antibiotics?

The redlight treatment is harmless and is suitable for all skin types. People with low blood pressure or who are pregnant, suffer from epilepsy or increased light sensitivity, or are on medication that causes increased light sensitivity (e.g. antibiotics or St. John? s Wort) should, however, refrain from the treatment.

Safety and Usage Guidelines

For most people, red light therapy is safe to use daily and cannot be overdone. It is non-invasive and has virtually zero risks and side effects. However, if any extraordinary results or adverse effects are noticed, it is advised to stop the treatment and consult a physician.

Toxic Skin Condition Post-mRNA COVID-19 Vaccination

Identifying Severe Skin Conditions Post-Vaccination Following administration of the BioNTech mRNA vaccine, a small subset of individuals may develop severe and complex reactions. These reactions are often misdiagnosed or misunderstood due to their rarity and diverse presentation. This essay examines a case characterized by severe skin conditions, systemic symptoms, and complications such as hypercalcemia and crystal formation. It highlights the need for accurate diagnosis, holistic management, and increased awareness of these rare but significant vaccine-related adverse events. Initial Symptoms and Misdiagnoses Severe symptoms began shortly after the first dose of the BioNTech vaccine, initially presenting as petechiae, diagnosed by a rheumatologist. However, following the second dose, symptoms rapidly escalated, resulting in intense burning pain and thinning of the skin. The skin on the legs and thighs became paper-thin and could tear with the slightest touch, with the affected area e...

Dysferlin Protein: Key Roles, Genetic Locations

The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Is ME CFS connected to Spinal Muscular Atrophy (SMA) or Post Polio?

Today, I understand why Spinal Muscular Atrophy (SMA) received little attention, particularly in the mid-50s. This complex and debilitating genetic illness was poorly understood, and patients' symptoms were often minimized or even dismissed. For more information, please visit the Spinal Muscular Atrophy (SMA) page on MalaCards . Even now, many neurologists lack detailed knowledge of SMA, and comprehensive examinations mentioned in research are rarely pursued. In 2008, while investigating permanent adrenal insufficiency, an MRI ordered by my endocrinologist unexpectedly revealed Chiari Malformation II. However, surgery in 2009 brought no improvement. In 2010, a DNA test showed a genetic marker in the ACTN3 gene: https://www.malacards.org/search/results?q=ACTN3%20gene%20and%20Spinal%20Muscular%20Atrophy%20(SMA) A 2015 MRI revealed ankylosing spondylitis, multiple Tarlov cysts, stenosis at L4 and L5, spinal canal narrowing, and widespread degenerative changes. Surgery on L4 and L5 ...
