Medical explanation of the effect of light therapy

Today we know that sun light acts like a natural clock for many of our physiological processes. Bright light travels in the form of electric impulses via the eyes and the optical nerves to the nervous system's inner timer in our brain. This "time giver" processes the information about light and darkness and instructs other parts of the brain to rhythmically distribute chemical messengers. Bright light thus stimulates the production of chemical messengers which influences the mood and suppresses the production of the body's sleep inducing hormone.

How to use the DAVITlight therapy units

The light therapy boxes can be used for the following symptoms:

winter depression
non-seasonal affective disorder
premenstrual syndrome ("PMS", "days before the days")
sleep disorders

Some basic information before using the light therapy units

Before use, kindly check that the instrument is in functional order and that there is no sign of damage. Phototherapy instruments must only be operated in dry and closed rooms that are free of any explosion risks. The device is not suitable for use in the presence of flammable anesthetic mixtures with air or with oxygen or nitrous oxide. The instruments must be standing free and should not be exposed to sun.

How to carry out light therapy

Place the instrument on an even surface and connect the plug with a wall socket. Sit down in front of the instrument and keep a distance of approx. 55cm in case of the LD 72 / LD 72-2, a distance of approx. 45cm in case of the LD 110 and a distance of approx. 50cm in case of the PhysioLight LD 220. The treatment time with the LD 72 is at the above mentioned distance approx. 2 hours, approx. 1 hour in case of the LD 110 and approx. 30 minutes in case of LD 220. If you use the LD 72, LD 72-2 or LD 110 move the tilting switch to "On" and the device begins to glow. If you use the LD 220 you have to turn the control knob of the timer clockwise. Then the light therapy unit begins to glow. After the preset application time has expired, the LD 220 switches off automatically. The LD 72, LD 72-2 and LD 110 must be switched off manually.

Keep your eyes open during the treatment. You are in the position to read, watch TV or carry out any other activities.

After every 1 - 2 minutes you should look for a few seconds into the light source. A constant staring into the light source must be avoided. If you want to cover the phototherapy instrument after use allow the instrument to cool down at least 15 minutes.

Important: In order to be protected against UV-rays, the light box must only be operated with its original protective filter in place.

Fastening of light therapy units LD 72, LD 72-2 and LD 110 on the wall

The light therapy units LD 72, LD 72-2 and LD 110 can be mounted on the wall.

On the back side of the top of these light therapy units there is an opening in the middle below the air vents (see illustration).

At this opening the units can be fixed on the wall with a screw. Depending on the type of wall, an appropriate screw must be used, may be with pegs. E.g. a round head wood screw which is screwed into an expansion anchor. The screw and the anchor are not included in the scope of delivery.

The screw head must not exceed a max. height of 6mm and a max. diameter of 8mm . The distance from the wall to the screw head can be max. 8mm . The screw shaft may have a maximum diameter of 4mm .

The load on the screw and the condition of the wall, to which the unit has

to be mounted must have a capacity of at least 3kg . The base of the light therapy units LD 72, LD 72-2 and LD 110 must

be unscrewed before the fastening. Therefore the right and the left thumb screw must be completely removed from the foot. So the foot can be removed completely from the upper part of the unit. Afterwards the screws have to be screwed in for safekeeping.

Operation of the light therapy units with the DAVITONwith floor stand

The activated DAVITON (not included in the scope of delivery) reminds you with an acoustic signal every 90 seconds to look for 3 seconds direct into the light source. The light therapy unit PhysioLight LD 220 can be used together with a floor stand (not included in the scope of delivery).

Frequency and time of treatment

If the treatment takes place at your practitioner it should initially be carried out 5 times per week for a period of 2 - 3 weeks; thereafter, 3 times per week for a period of 2 - 3 weeks. After that, the treatment should take place as needed or when the symptoms occur again. At home, the treatment can take place daily, especially during autumn and winter time. The best treatment time for winter depression and the non seasonal depression is the early morning or the time of the lowest mood. The premenstrual syndrome ("PMS") is treated most effectively in the evening. As for abnormal shifts in a person's day-and-night rhythm (circadian rhythm), i.e. going to bed very early and very early awakening) there are two ways of treating them: if you go to bed very early and get up very early, treatment is most effective in the evening. If you go to bed very late and wake up very late, a treatment is best in the morning.

Side effects and contraindications

By using phototherapy the following side effects have been observed: Headaches, nausea, irritability and burning of the eyes can occur rarely for a short period. An absolute contraindication that means circumstances that do not allow the use of light therapy units is not known so far.

Please take care in case of all types of eye diseases and the eye specialist should be consulted before. In case of patients being under treatment with lithium or medicine for example Fluoxetine, Imipramine et al., which increase the sensibility of the eyes on light a supervision of the light therapy by an eye specialist could be considered.
