Ice-hockey players combat winter blues with daylight
Hannu Jortikka, the former head coach of the KHL hockey team Admiral Vladivostok, shares his experiences from back when he tried to motivate his players to use the Valkee daylight headset in order to combat the effects of winter blues and to compensate for jet lag.

Melatonin reduction is not the goal of transcranial daylight therapy
To the contrary of what was specified in the research report by Bromundt et al in the specialist journal Chronobiology International, the transcranial ear canal light therapy with the Valkee does not target the 'sleep hormone' melatonin.

90-minute days in space
Shift workers, who have no regular rhythm of sleeping and waking and don't sufficiently expose their bodies to light during the day are aware of the consequences. Working hours in space are an extreme form of shift work, when the Sun practically rises and sets almost 16 times per day.

Improved efficiency thanks to light via the ear canal
Anyone can already subjectively feel the extent to which sun and natural light can positively affect people's moods. Research now shows that exposure to sunlight can improve cognitive performance and attention. A test with athletes to whom psychomotor speed is an important factor yielded a surprising result.

Effects of Light and Supplements for Natural Light on our Well-being
The activity of every human cell is synchronized with the sun, which is also the main food source for most life forms on Earth. But modern life makes it almost impossible to enjoy enough and full daylight in a natural setting. Shift work, long-distance travel, and indoor office lighting, as well as changes of the seasons affect the amount of light we get regularly exposed to.

Valkee also proved to increase the capacity of reaction in athletes
The Valkee light therapy device is suitable for the treatment of winter depression and to reduce jet lag symptoms. However, these are not the only attributes. The small device with its earplugs showed its ability to increase the capacity of reaction. This brings to athletes who play sports such as hockey, ice hockey, football, handball, basketball, tennis and other sports where a rapid reaction capacity is required, a special advantage.

Study, Published In BMC Psychiatry: Even a Small Dosage of Bright Light via Ear Canal Alleviates SAD Symptoms
Two aspects are at the heart of the Valkee research: to understand the working mechanism of transcranial bright light (TBL), and to determine its clinical effectiveness on people. A research paper on the mechanism of TBL and melatonin suppression has already been published in the journal Chronobiology International. Now, the results of a TBL dose response study in treating patients suffering from symptoms of seasonal affective disorder (SAD) has also been published in the peer-reviewed US journal BMC Psychiatry.

How can I change the settings of the new Valkee light therapy device from Finland?
The light setting of the Valkee2 light therapy device can be changed. The video shows how you can shorten the duration of treatment or reset to the maximum treatment duration of 12 minutes. On the Valkee2, you can set the duration of light therapy to 12, 9, 6 or 3 minutes.

How to use the Valkee2 Light Therapy Device from Finland?
The Valkee 2 light therapy device is actually quite simple to use. It is important to know how the individual components should be joined together, and that the first plug should be placed into the air before the Valkee 2 is turned on.

The human brain responds to light that is not received via the eyes
A study shows that light that is sent to the brain via the ear canal rather than the eyes has an effect on the interaction of attention and emotion.

Light doesn't just act via the 'sleep hormone' melatonin
The uplifting and mood-lifting effects of light are not just a result of the interaction with the hormone melatonin. Now, while the research initially focused on the study of light at night, there is evidence that the brain itself is sensitive to light.

Studies On The Effect Of Transcranial Light Over The Ear Canal
It is quite a recent discovery that light information can also be transported over the ear canal to the brain. Research results have been incorporated into the concept for the Valkee light therapy device. From the beginning, the development of the Valkee device was accompanied by several studies that were dealing with its mode of action.
