IHG (InterContinental Hotels Group) has partnered with Healthe by Lighting Science, a provider of LED lighting solutions, to pilot the use of circadian lighting to help guests sleep better while traveling. Crowne Plaza Atlanta Airport will be the first property to install the Journi Mobile Task Light in guest rooms. The product allows access to the “alertness and focus-enhancing spectrum” during the day, then changes to the “warm, sleep-enhancing spectrum” at night. It helps regulate the body’s circadian rhythm or 24-hour internal body clock. The test is part of IHG’s moves to help guests sleep, including the use of aromatherapy, pillow menus and light colors. Brian McGuinness, senior vice president of global guest experience shared services, said IHG is the first hotel company to use the lighting product. Any extension of the pilot will be decided after the test phase.
