The electromagnetic radiation of the sun has its greatest intensity in the range of visible light. This also contains infrared radiation and about 7% UV radiation. All in all, the radiation arriving on earth depends very much on the sun and the weather.

The BluRoom ™ works with UV - ultraviolet light. That is why we would like to inform you about this.


Classification, Properties and Effects of Ultraviolet Light


Since ultraviolet light differs greatly in its properties and effects, it is divided into UV(A), UV(B) and UV(C).

Range of UV light

Wavelength in nanometers


390 - 315


315 - 280


280 - 10

The long-wave UV(A) mostly reaches the earth's surface. It causes above all a browning of the skin and is among other things responsible for skin aging.

The UV(B) is absorbed by the atmosphere and by clouds to about 90%, only a small part reaches the earth's surface. This part of the UV radiation has a considerable biological effect mainly on the human skin. One of the most important effect is the conversion of the precursors of Vitamin D (7-dehydro-cholesterol or provitamin D 3) into the actual Vitamin D3 (cholecalciferol). This is then built up in the liver and afterwards in the kidneys to the effective Vitamin D Hormone.

The short-wave UV(C) is largely absorbed by the ozone layer in the atmosphere and does not reach the earth's surface. This range of UV is primarily used for disinfection for example of operating rooms.

UV in BluRoom ™


In the Blu Room™, during the first 3, 6 or 9 minutes nine lamps emanating narrowband UV(B) are switched on.

Narrow band UV(B) limits the light emission to a therapeutically relevant range of maximum 311 nm.

UV(B) penetrates less deeply into the skin, thereby eliminating the pigmentation effect (= browning). As experience also shows, when exposed to the sun the skin is more robust against effects such as redness and sunburnt.

The UV light is extremely intensified by the unique spatial geometry and reflection of the room and moreover, when the lamps are turned off the radiation remains concentrated in the room for a whole time, with a maximum around the bed in the center of the room.

This causes the deep relaxation and the activation of the self-healing powers.

Long-term studies on the effects of narrowband UV(B) are not yet available. In the more than 20 available Blu Rooms™ worldwide 200,000 sessions have been experienced. Apart from short-term reddening of the skin, there were no side effects.

An important effect of the Blu Rooms™ is the conversion of the precursors of Vitamin D into the effective Vitamin D3. Due to the strong reflection of the UV(B) rays, an enormous amount of Vitamin D3 can be formed in the short time. This result could not be achieved even in summer.

The truly effective form of Vitamin D Hormone is produced in the human body itself.




In the middle of the last century the German Biophysicist Dr. Alfred Popp proved like his Australian colleagues that living cells contain the smallest Light Parts, so-called photons. Photons stored in cells are called Biophotons. He could prove that cancer cells do not contain Biophotons anymore.

In recent years, it has been shown that plants and animals derived from organic agriculture or animal welfare contain more Biophotons than those from conventional agriculture.

The content of Biophotons in living cells of humans, animals and plants is significantly increased by the stay in the BluRoom™.
