Sleep deprivation severely compromises the ability of human beings to respond to stimuli in
a timely fashion. These deficits have been attributed in large part to failures of vigilant …

Light is known to elicit non–image-forming responses, such as effects on alertness. This has
been reported especially during light exposure at night. Nighttime results might not be …

Sleepiness and sleep propensity are strongly influenced by our circadian clock as indicated
by many circadian rhythms, most commonly by that of core body temperature. Sleep is most …

Although complaints of impaired daytime functioning are essential to the diagnosis of
primary insomnia, objective evidence for cognitive dysfunction has been hard to establish. A …

With ageing, an increasingly disturbed sleep is reported as a significant complaint affecting
the health and well-being of many people. The available treatments for sleep disturbance …

In the present paper, an attempt is made to summarize current knowledge concerning the
daily body temperature rhythm and its age-dependent alterations. Homeostatic and …

Circadian rhythms in health and disease have most often been described in terms of their
phases and amplitudes, and how these respond to a single exposure to stimuli denoted as …

The transition from sleep to wakefulness entails a temporary period of reduced alertness
and impaired performance known as sleep inertia. The extent to which its severity varies …

The regulation of sleep and wakefulness is well modeled with two underlying processes: a
circadian and a homeostatic one. So far, the parameters and mechanisms of additional …

Abstract Study Objectives: Sleep propensity and skin temperature are functionally related. In
young adults, changes of skin temperature within the comfortable thermoneutral zone affect …
