The effects of post-awakening light exposure on the cortisol awakening response in healthy male individuals
Is the cortisol awakening rise a response to awakening?
Effects of artificial dawn on sleep inertia, skin temperature, and the awakening cortisol response
TLDR
The physiology underlying the positive effects of artificial dawn on the dissipation of sleep inertia involves light sleep and an accelerated skin temperature decline after awakening, which are suggested to be explained by effects of Artificial dawn on skin temperature and amount of wakefulness during the 30 min prior to the alarm.
The cortisol awakening response, seasonality, stress and arousal: A study of trait and state influences
Study protocol for measuring the impact of (quasi-)monochromatic light on post-awakening cortisol secretion under controlled laboratory conditions
TLDR
The current work provides the study protocol for an ongoing research project that is intended to explore the spectral dependencies and to discuss measures of emotional state and cognitive functioning potentially related to the cortisol awakening response.
Assessing the daily stability of the cortisol awakening response in a controlled environment
TLDR
The stability of the CAR profile and total cortisol secretion, but not awakening cortisol levels or the magnitude of increase, was demonstrated across two consecutive mornings of measurement in a highly-controlled environment.
Effects of Artificial Dawn and Morning Blue Light on Daytime Cognitive Performance, Well-being, Cortisol and Melatonin Levels
TLDR
Exposure to an artificial morning dawn simulation light improves subjective well-being, mood, and cognitive performance, as compared with DL and BL, with minimal impact on circadian phase.

Transition from dim to bright light in the morning induces an immediate elevation of cortisol levels.
TLDR
The data unambiguously demonstrate an effect of light on the corticotropic axis that is dependent on time of day.
Light affects morning salivary cortisol in humans.
TLDR
It is demonstrated that light conditions in the early morning have a strong impact on the morning-cortisol peak, but that evening cortisol levels are unaffected by light.
Awakening cortisol responses are influenced by health status and awakening time but not by menstrual cycle phase
TLDR
The data suggest that the morning cortisol response is influenced by the awakening time, and health status and age appear to have an impact on this marker of adrenocortical activity.
The cortisol awakening response - normal values and confounds.
TLDR
It is strongly suggested that neither age, nor the use of oral contraceptives, habitual smoking, time of awakening, sleep duration or using / not using an alarm clock have a considerable impact on free cortisol levels after awakening.
