Best Intranasal Light Therapy Devices – The Latest Light Therapy Innovation

Intranasal light therapy is also known as intranasal photobiomodulation. The nose is targeted for the abundance of blood vessels found within the nasal passages. The treatment uses a small device that attaches to one nare and emits visible red light into the nasal passageway. The tissues and blood vessels inside the nose absorb the light photons. The bony membrane located at the back of nasal passages is very thin and almost transparent. As such, red light and near infrared light readily passes into the brain. The therapy is a non-invasive, non-chemical treatment, which has been proven in many different scientific studies to provide a number of healing effects from the biological and chemical changes that occur.


How Red Light Works

Red light falls on the light spectrum between 600 and 635 nm. Near infrared shines at a wavelength of approximately 810 nm. When the light enters the blood vessels, it is converted into energy, which stimulates blood vessel linings to release nitric oxide. The natural gas causes blood vessel dilation. As a result, blood pressure decreases, blood circulation improves and cells receive oxygen and nutrients faster. When cells absorb red light, mitochondria organelles within the cells produce more energy. With increased energy levels, the cells function more efficiently. Studies also indicate when neurons in the brain come in contact with the light, they are stimulated to release various types of beneficial neurotransmitters.

Scientific Evidence

One group of scientists from China were interested in determining if intranasal light therapy might have any effect on vascular disorders. During the study, 60 participants received low-intensity red light therapy for 10 days. After a three-day break, the group was again exposed to the red light. A control group received therapy using a device that emitted typical white light. Following treatment, the researchers analyzed the subjects’ blood. They found on average, total cholesterol levels dropped 26 points. Bad or LDL cholesterol decreased by 10 points. Good or HDL cholesterol increased by three points and triglycerides also dropped by 10 points. Light therapy inhibits the clumping or sticking action of red blood cells, which also enables the blood to flow more freely.

  • Stroke – Another Chinese study evaluated the effects of red light intranasal therapy on stroke patients. The participants underwent SPECT scans to assess blood flow in the brain following treatment. Imaging studies showed that the treated subjects had better blood circulation on the side exposed to red light treatment.
  • Alzheimer’s – One study involved volunteers diagnosed with cognitive impairment. The memory capability of each individual was assessed prior to receiving treatment. The participants were exposed to intranasal red light therapy every morning for one month. After reevaluating the subjects, researchers learned the patients receiving red light therapy demonstrated improved memory. Their melatonin levels also increased and the participants felt calmer. Researchers theorize that light therapy also elevates serotonin levels.
  • Parkinson’s – Adults diagnosed with Parkinson’s disease were exposed to intranasal treatments for 30 minutes every morning for 20 days. At which time, 66 percent experienced a reduction in symptoms. In a similar study, 89 percent of patients experienced some degree of symptomatic relief. Scientists believe that improvements occurred due to the increase of dopamine and melatonin levels, the decrease in levels of malonhialdehyde and the destructive enzyme known as cholecystokinin-octapeptide.
  • Migraines – Chinese researchers evaluated the effects of red light therapy on patients suffering from chronic migraines. The test subjects were exposed to intranasal therapy for 30 minutes daily for five days. Following a two-day break, they underwent five more days of treatment. The number of headaches were reduced in approximately 90 percent of the test subjects. The pain relief effects occurred secondary to the increased levels of natural endorphins being released by the brain.

VieLight 633

The VieLight 633 is a portable, easy to use intranasal light therapy device, which contains a single LED diode made from clear, durable polycarbonate. The diode delivers visible red light at a wavelength of 633 nm. The light does not produce heat. Although, the sensation of having the LED in your nose may initially feel strange, the VieLight does not cause discomfort. Users merely insert the diode into the desired nostril. A gentle clamp on the end of the applicator keeps the LED in place for the duration of the treatment session.

The light therapy diode is connected to the applicator cable, which plugs into the battery-powered unit. The power pack features an automatic timer and a battery low indicator. The miniature power pack functions using one AA battery. Depending on the brand of battery used, the device functions for up to 20 hours before requiring a battery change. The diode is completely encased, which means the area is easily cleaned after treatments. The lightweight battery pack weighs a mere 10 ounces and measures approximately 4 inches x 2 inches x 1 inch.

The hands-free design of the unit enables you to receive treatment and accomplish other desired tasks. Or, simply sit, relax and listen to music, watch TV or read. The VieLight provides 20 minutes of continuous red light treatment before automatically turning off. VieLight recommends using the device before bedtime. Although the LED does not cause side effects, you should avoid looking directly at the light. Results vary from one person to the next and depend on the condition for which you are attempting to have symptomatic relief. So, you must be committed to using the device nightly.

The VieLight comes with the LED diode applicator, the power pack controller, one AA battery, a convenient carrying pouch and an instruction manual. The intranasal VieLight also comes with a 6-month money back guarantee and a one-year manufacturer’s warranty against defects.

VieLight 810

The VieLight 810 provides convenient hands-free treatments by emitting invisible, near infrared light at a wavelength of 810 nm. The specially-designed diode delivers a more focused beam of light in 10 Hz pulses. The near infrared light wavelength is though to penetrate deeper into tissues and particularly into the underside and mid-brain regions.

The wavelength is also similar to the alpha waves transmitted by the brain when in a state of relaxation or meditation. As such, VieLight recommends using the device before bedtime. However, some feel energized after infrared intranasal therapy and prefer using the unit in the mornings. Treatment sessions last approximately 20 minutes. After which time, the devices turns itself off.

VieLight is simple to use. Insert the AA battery into the power pack, and connect the diode applicator by plugging the cable into the controller jack. Insert the LED diode into your nose, and turn the unit to the on position. The diode stays in place with the help of an exterior clamp. The diode is covered and protected by transparent polycarbonate. In this way, the diode is also easily cleaned.

At 10 ounces in weight and measuring 4 inches x 2 inches x 1 inch, the compact VieLight is portable and does not restrict physical movement. Thanks to the handy carrying pouch, the unit is also easily packed into a purse or suitcase for travel. The controller features a light display for indicating when the unit is functioning and the amount of life left in the battery.

The intranasal light therapy unit comes with a six-month money back guarantee and a one-year manufacturer’s warranty. Replacement diode applicators are also available if wear and tear occurs or you need one for another member of your household.
