Sleep radars

Sleep radars are new technology for contactless sleep measurement. It is widely considered to be better than actigraphy, and easier and cheaper to use than PSG, which is the gold standard for objective sleep registration. The research group uses sleep radars from Somnofy, to gain insight, among other things, into how Quick Returns (short rest time between two work shifts) affect sleep.

Actigraphs

The research group uses three models of actigraphs from Philips: Actiwatch 2, Actiwatch Spectrum and Actiwatch Spectrum Pluss.

Light lab

In Christies gate 12, the research group has a light lab. The light lab, which is partly sponsored by the company Glamox, provides unique opportunities to simulate work under different lighting conditions. Since the lab was established, the research community has conducted several research studies that have investigated the effect of different lighting conditions at night work.

Sleep lab

The sleep lab has an isolated room adapted for research studies in a controlled environment where the researchers can follow the test person (s) from an external control room.

Other laboratories

In Christies gate 12, there is also a video analysis room, lab for individual testing, analysis room and a multiple testing lab for research studies with up to five participants simultaneously.

Light boxes

A light box/light therapy lamp is a specially designed lighting device, which emits light with a certain intensity, usually around 10,000 lux. The light’s wavelength influences the treatment effect, but most light boxes emit white light that contains all wavelengths. It is the blue wavelengths that have the greatest effect on the circadian rhythm. However, the effect of the light depends on when in the day you are exposed to the light. Light can be used both to speed up and delay the circadian rhythm.
