Red Light Increases Alertness During 'Post-Lunch' Dip

摘要

Acute or chronic sleep deprivation resulting in increased feelings of fatigue is one of the leading causes of workplace incidents and related injuries. More incidents and performance failures, such as automobile accidents, occur in the mid-afternoon hours known as the "post-lunch dip." The dip typically occurs from 2-4 p.m., or about 16-18 hours after an individual's bedtime from the previous night.
