FAQ on Valkee

We will continue to add your frequently asked questions to this page.

Are there benefits of using Valkee in summer?

Summer does not automatically mean necessary light exposure. If we spend time inside - commuting, working, home - we do not get the needed light exposure. Office or home lighting is in almost all cases too dim (~300 lux by intensity) whereas the needed exposure is achieved at bright sunlight outside (80,000 - 150,000 lux by intensity).

When should I use Valkee?

Bright light has shown efficacy across multiple mood conditions from seasonal affective disorder to job stress and PMS. Valkee especially relieves symptoms like tiredness, anxiety and reduced cognitive performance typical for 'winter blues'. In clinical trials, 9 of 10 participants suffering from severe symptoms experienced a total relief.

What time of the day is it best to use Valkee?

70% of users have stated that positive effects are best realized during the morning and 30% have stated that they achieve the best results in the evening. Start using Valkee in the morning preferably 30-60 minutes after waking up. If you do not realize positive results after 3-5 days, use Valkee 1-2 hours prior to going to bed in the evening.

What scientific evidence do you have?

Valkee has shown that the human brain is photosensitive, that bright light via the ear canal stimulates the brain, and that such stimulation is effective to treat mood conditions like anxiety, tiredness and reduced cognitive performance in 'winter blues' - all new and revolutionary results. Research was started in the University of Oulu in 2007, and has included over 20 scientists and 350 study subjects, making it one of the largest programs in bright light.

How was Valkee born?

In 2005 biologist Juuso Nissilä introduced his childhood friend Antti Aunio to the concept of in-ear bright light therapy. Since his time as a student of biology, Juuso had been conducting research to test and prove that the human brain is photosensitive, in the same way that many animals brains have been proven to be. From this exploration Nissilä developed the concept of Valkee and with Aunio, quickly turned this brain science into the current Valkee product.
