The natural light provided by the sunrise may contribute to a reduction in sleep inertia effects. Research simulating increase of light at dawn was shown to potentiate the cortisol awakening response (CAR). [5] The CAR is a spike in blood cortisol levels following awakening, and is associated with the return to an alert cognitive state.
Additionally, lack of sleep causes increased anxiety-like behaviors and impairs the brain's ability to block out unimportant stimuli when performing tasks requiring attention. Disruptions in important brain circuits and the downregulation of proteins necessary for cognitive stability are the causes of these behavioral abnormalities. [ 30 ]
