According to foreign media reports, CROWNE PLAZA is experimenting with circadian rhythm lighting to help its guests sleep better.

IHG, the owner of the hotel chain, stated that special standalone lights have been installed on the bedside tables at their Atlanta airport hotel for experimental research to understand how the correct spectrum can help maximize guests' sleep.

It is reported that IHG is collaborating with Lighting Science to trial this technology. Lighting Science claims that their patented spectral technology can produce a spectrum that enhances alertness and focus during the day, and then easily transitions to a warm, sleep-enhancing spectrum at night.

The experimental lighting fixtures utilize proprietary technology that can add or remove blue 480-nanometer wavelength light, which is considered a key wavelength affecting circadian rhythm, to achieve optimal biological benefits.

Guests can change the color of the room lighting to blue, red, green, yellow, or select "active" or "relax" modes.

Two dual-spectrum light fixtures have been installed in each room.

IHG states that lighting can help regulate the body's circadian rhythm or 24-hour biological clock, which affects vital biological functions such as sleep, hormone levels, body temperature, and metabolism. (Compiled by LEDinside James)
