What is Valkee for?

Valkee headset projects bright light into the brain to relieve symptoms of Seasonal Affective Disorder (SAD) also known as winter blues. Many people recognize feelings of some of the most typical symptoms, including anxiety, tiredness and reduced cognitive performance. Using the headset for just 12 minutes a day can improve mood and alertness particularly in dark times of the year like autumn and winter. Valkee has also been tested to improve psychomotor speed of professional athletes and attention performance of healthy adults.

What kind of evidence do you have to prove that it works?

Valkee and third-party researchers have found evidence that: 1) the human brain is photosensitive i.e. bright light stimulates brain activity, 2) bright light delivered to the brain via the ear canal (and not only via eyes) does stimulate the brain, and that 3) such stimulation is effective to treat mood conditions like anxiety, tiredness and reduced cognitive performance, typical symptoms of SAD. Systematic research with conventional bright light therapy started in the 1980’s. Research of transcranial “ear light” was started at the University of Oulu in 2007, and has thus far included efforts of over 20 scientists. Read more about scientific evidence here.

Can my ears sense light?

The bright light is not meant for our ears but for our brains. In order for light to activate the parts of the brain that influence our mood, the brain needs to get exposed to light. The ear canal merely provides a convenient passage through the skull for the bright light to be captured by the photosensitive structures of the brain.

Isn’t it dangerous to shine bright directly into human brain?

No, it isn’t. Bright sunlight also penetrates the human skull and the brain is naturally exposed to light during bright sunny days. Bright light treatment in the wintertime is therefore nothing new to your brain. On the contrary, it supplies your brain with the light signal that it is missing during darker times of the year like autumn and winter. And it’s free of the UV-radiation that natural sunlight contains.

Is it safe to use Valkee?

Yes, if you use the device according to instructions. The recommended dose of Valkee bright light is 12 minutes once a day.

Are there any side effects of using Valkee?

The most common side effect is a harmless sense of heat in the ear canal. Very few users have experienced temporary headache, sleeplessness and mild nausea. Changing the time of treatment from morning to evening or vice versa might help to improve the effect of treatment and relieve some of the side effects.

How is using a Valkee different from using an ordinary bright light lamp?

The main point of difference is convenience: Valkee is small and portable so you can take it anywhere with you. Conventional bright light devices tie people down to sit in front of them for 30 minutes or more. With Valkee, you only need a 12 min dose.
