Light therapy lamps : How does it work?

Light therapy consists of facing a light therapy lamp which transmits light to the eyes. The intensity of the light should be between 2500 and 10 000 lux (light units).  It is the retina via the neurotransmittors that inhibit the melatonin, a sleep hormone which is at the root of the problems linked to a loss of light.  This homone is normally secreted at night for us to sleep. The fact that this sleeping drug is naturally blocked during the day helps us to find out natural energy.

How to use the light therapy lamps

First you have to remember that light therapy lamps used as treatment in hospitals and at home respond in the same way as any normal medecine.  This is why you should verify that the lamps have an agreed EU license.

The origin of light therapy lamps are reserved for medical use (by a GP or at the hospital).  Today light therapy lamps may be used at home, at the office in response to normal usage.

The power will be the first factor in the choice of a lamp, of course the more powerful the lamp the more the use will be a greater comfort.

Each session should be done in the morning.  The user must place the lamp at eye height or just underneath the eyes.  It is not necessary to look at the lamp but it is important that the retina swims in the light coming from the light therapy.

The length of the session must be between 30 minutes and 2 hours (30 minutes at 10 000 lux or 2500 lux for 2 hours).

The effects on the morale can be felt quite quickly, from the first couple of days, but may take 10 days for others.

There are very little indications against light therapy but it is important to consult a doctor when the person suffers with their eyes or is taking photosensitive medication.
