You have surely heard talk of sunrise simulators, the devices which simulate the rising of the sun to guarantee a gentle awakening. These devices may be used in a complementary manner alongside light therapy lamps.

The sunrise simulator is not a simple gadget but actually a class 1 medical device which offers real physiological effects to those who use it. Indeed, numerous studies show that the sunrise simulator has an effect on the mood and on cognitive performance.
However, if you seek to treat a depression problem or a sleep problem, it is preferable to use a light therapy device. The sunrise simulator will then be an excellent complimentary device to reinforce the effects of light therapy.
