Dawn simulation

Lumie has used research findings such as those below to develop the Bodyclock range of dawn simulators.

Dawn simulation in teenage children
In Press
80% or more of the subjects who used the (original Bodyclock) and their parents found ease of waking superior (twice as easy as usual) and preferred it to other methods of awakening. Since the clock is a .. novel technology placebo effect could not be ruled out.

Is dawn simulation effective in ameliorating the difficulty awakening in seasonal affective disorder associated with hypersomnia?
J Affect Disord. 2002 May;69(1-3):231-6
Compared to a placebo condition, dawn simulation appears effective in decreasing both prospectively assessed morning drowsiness and retrospectively assessed difficulty awakening. The symptom of difficulty awakening is consistent with the phase delay hypothesis of SAD. Assessment of difficulty awakening could prove useful in the evaluation of SAD.

People with SAD frequently have difficulty waking in the morning. This study shows that using a dawn simulator (Bodyclock) can help.

Dawn simulation and bright light in the treatment of SAD: a controlled study
Biol Psychiatry. 2001 Aug 1;50(3):205-16
Dawn simulation was associated with greater remission and response rates compared to the placebo and compared to bright light therapy. The hours of sunshine during the week before each assessment were associated with a positive clinical response.

Dawn simulation vs. lightbox treatment in SAD: a comparative study
Acta Psychiatr Scand. 1998 Jul;98(1):73-80
61 outpatients with winter depression were randomised to receive either lightbox treatment with bright light or dawn simulation treatment in their homes. Patients' ratings of improvement at the end of treatment showed a mean of 40% in the dawn simulation group and 57% in the lightbox group.

A controlled study of dawn simulation in subsyndromal winter depression
Acta Psychiatr Scand. 1993 July;88(1):67-71
Dawn simulation was well tolerated and resulted in marked improvement in a group of subsyndromal SAD subjects. Both the rapid (placebo) and slow conditions were associated with an improvement over baseline but there was a significant dose response effect favouring the longer dawn signal.

Dawn simulation treatment for Winter Depression
SLTBR Abstracts. 1993 June
Reviewing four previous studies the author states that the degree of improvement with dawn simulation is similar to that seen in previous studies of bright light boxes.

I don't know what kind of light to buy, or where to buy it. I bought a growing light, I'm not sure if this is the right light or not.
I have bi-polar and seasonal depression. Any suggestions would be apprietated!

I have recently graduated from a BA Sculpture course, my work is specifically concerned with the influence of light and colour on the viewers’ mood. It is my ultimate ambition to work as an artist making light instillations for use in therapy. I am writing to find out whether you know of any possible avenues worth perusing, and any advice you may have on how to get involved with this type of research. I am based in the North of Scotland. I would be extremely grateful for any help or advice you may have. Thank you.
