Study Finds That Intranasal Light Therapy Reduces High Blood Pressure and Cholesterol

Study - Intranasal Light Therapy Reduces High Blood Pressure and CholesterolIn a rigorous study recently published in the International Journal of Photoenergy, researchers found that intranasal low-intensity laser therapy regulates the factors that affect vascular diseases such as high blood pressure and cholesterol. This technology is often known as Intranasal Light Therapy, a technology made available by MedicLights Research Inc., of Toronto, Canada, and marketed as Vielight, Qi-Light, and RadiantLife LT.

According to the study leader, Professor Timon Liu of South China Normal University in Guangzhou, China: “Intranasal low-intensity laser therapy has been applied to treat hyperlipidemia, the blood-stasis syndrome of coronary heart disease, myocardial infarction, and brain disease such as insomnia, intractable headache, Alzheimer’s disease, Parkinson’s disease, post-stroke depression, pain in the head or face, migraine, cerebral thrombosis, diabetic peripheral neuropathy, cerebral infarction, acute ischemic cerebrovascular disease, brain lesion, schizophrenia, cerebral palsy, and mild cognitive impairment.”

The results of this study further establishes intranasal light therapy as a credible, non-drug treatment to improve conditions of high blood pressure and cholesterol, which would help to reduce the risk of heart attacks and strokes.
Researchers at South China Normal University worked with the medical practitioners at the Shanghai Pudong District Hospital to investigate the effect of intranasal laser therapy on 90 patients with coronary heart disease. They conducted the study over a period of three months in 2008 under double-blind, placebo-controlled conditions; criteria that help to define a rigorous study. The research examined the changes in key factors that affect blood pressure and cholesterol profile.

High blood pressure is a condition that increases the risk of heart attack. It is affected by the “thickness” and flow quality of blood; the factors that contribute to it are blood, plasma and redox viscosity, red blood cell aggregation, and red blood cell concentration. Results show that intranasal light therapy significantly reduces these factors.

The wrong types of fat in the blood can cause the formation of plaques in the blood vessels, increasing the risk of blockages that lead to heart attacks. The combination of plaques with high blood pressure also makes a deadly risk recipe for stroke. Blood lipid, total cholesterol, triglycerides, high and low density lipoprotein (HDL and LDL) and apolipoprotein are related factors. Results show that intranasal light therapy significantly improves this profile, which would then reduce the risk of a fatal outcome.

The therapy not only reduces LDL (often labelled as the bad cholesterol), it also increases HDL (the good cholesterol). The South China study explains that the therapy influences this and the other phenomena by stimulating the body to restore homeostasis. The healthy person would be in homeostasis, a state when the systems in the body are perfectly balanced.
