In the case of the patient, the United States hospital installed the circadian rhythm lamp

A circadian rhythm lamp has been installed in the Philadelphia children's hospital to set a sleep - Awakening cycle for patients.

The lighting of the medical department in the hospital changes color and intensity in a day to reset the circadian rhythm of the patient.

These lamps are low - intensity warm colors in the morning, cold in the morning, high in the afternoon, and back to low - intensity warm colors at night.

It is specially used to buffer the hospital's disturbance of the patient's normal sleep - the awakening cycle. In the hospital, the daytime is usually not bright enough, or at night it is not dark enough to suppress the natural pattern of the human body. Therefore, the rhythm of the patient is often disrupted in the medical environment.

Regular sleep - the awakening cycle is regarded as an important clinical tool for the medical department, which treats children with medical problems, and these children also have potential behavioral conditions, such as depression, anxiety and autism.

Mary Alcaraz, a senior project manager, says children can also color the LED lights on their beds to play a "positive distraction" effect.

The hospital did not describe the luminaire as the so-called "people-oriented lighting", and did not participate in the scientific research on the effect of color adjustment.

Last month, a study concluded that correct lighting in a sanatorium could improve sleep, mood and behavior in Alzheimer's patients. (Editor: LED network James)
