Why use a daylight therapy lamp?
When the hours of daylight are noticeably shorter in autumn and people increasingly stay
inside in winter, the effects of a lack of light may become apparent. This is often described
as "winter depression". The symptoms can present themselves in a number of ways:
• Imbalance
• Low mood
• Lack of energy and listlessness
• Generally feeling under the weather
The cause of these symptoms is the fact that light – particularly sunlight – is essential for life
and has a direct effect upon the human body. Sunlight indirectly controls the production of
melatonin, which is passed to the blood only in darkness. This hormone shows your body
that it's time to sleep. That's why more melatonin is produced in months with less sunshine,
making it difficult to get up in the mornings because your body functions are powered
down. Use the daylight therapy lamp immediately after waking up (i.e. as early as possible)
to end the production of melatonin and to brighten your mood.
Lack of light also prevents the production of the happy hormone serotonin which is said
to significantly influence our well-being. The application of light thus yields quantitative
changes to hormones and neurotransmitters in the brain that have an effect on our activity
levels, our feelings and our well-being. To compensate for such a hormonal imbalance,
daylight therapy lamps can create a suitable replacement for natural sunlight.
In the medical field, daylight therapy lamps are used as compensation for the effects of a
lack of light. Daylight therapy lamps simulate daylight over 10,000 lux. This light can influ-
ence the human body and be used as a treatment or as a preventative measure. Normal
electric light, however, is not sufficient to influence the hormonal balance. This is because
in a well-lit office, the light intensity is just 500 lux, for example.
