Emotional Exhaustion

The core symptom of burnout syndrome is emotional exhaustion, which leads to impaired functioning on the job. During workdays, we use and deplete mental resources. Accumulation of effort spent throughout the workday might result in increased feelings of sleepiness, lack of energy, psychological stress, and burnout.


Research indicates that natural light is vital for our well-being, health & performance..

Light can, for example, have both direct and phase-shifting effects on people’s circadian rhythm. In addition, studies have shown that natural light exposure to higher illuminance levels can result in increased feelings of alertness and better performance. A recent work-study revealed beneficial effects of bright light exposure at eye level (light therapy) can improve employees’ alertness, vitality, and objective cognitive task performance, and influence physiological arousal measured with heart rate..

A bright light has been shown to positively impact alertness, vitality, and performance and may thus counteract stress and fatigue by helping recover decreased mental resources. Additionally, studies of sufferers of seasonal affective disorders (SAD) and of healthy people show that energy levels can be improved by exposing them to natural bright light.

“We are all light deficient and this deficiency may be the source of our physical and emotional problems.”
