Electric light in the evening delayed their circadian phase.

Second, we were not previously able to examine effects of a given variable (genotype, body part) on circadian phase.

Starting about two hours before bedtime, exposure to bright light will delay the circadian phase, causing later wake-up time and later sleep onset.

From usual bedtime until wake-up time, exogenous melatonin has no effect on circadian phase.

Electric light in the evening delayed their circadian phase; these results became well known.

Circadian rhythm disruption is primarily caused by the wrong timing of light in reference to the circadian phase.

The "time of day", the circadian phase, is signalled to the pineal gland, the body's photometer, by the suprachiasmatic nucleus.

Food intake varies during working hours compared to days off and truckers eat meals at the wrong circadian phase during the day.

The E-box is one of the top five transcription factor families associated with the circadian phase and is found in most tissues.

They are: circadian phase, sleep inertia, acute sleep deprivation and chronic sleep deficit.
