Changing traditional white-light lighting to blue-enriched white light helped office workers stay more alert and less sleepy during the day, in a new study. The research also showed improvements in subjective measures of positive moods, work performance, fatigue in the evening, irritability, ability to concentrate and focus and eye strain. Furthermore the workers reported improved sleep at night.
