Preliminary evidence that daily light exposure enhances the antibody response to influenza vaccination in patients with dementia

Enhancing lighting conditions in institutions for individuals with dementia improves their sleep, circadian rhythms and well-being. Here, we report first findings that exposure to brighter light during daytime may support the immune response to the annual ...

Optimized office lighting advances melatonin phase and peripheral heat loss prior bedtime

Jean-Louis Scartezzini, Mirjam Münch, Marta Benedetti, Lenka Maierova

Improving indoor lighting conditions at the workplace has the potential to support proper circadian entrainment of hormonal rhythms, sleep, and well-being. We tested the effects of optimized dynamic daylight and electric lighting on circadian phase of mela ...

Alertness in work environments : on the role of indoor daylight exposure

Victoria Eugenia Soto Magán

Light enables to see the world around us, while playing a key role in our biological functioning. During the last decades, light has become an important research topic for chronobiologists and neuroscientists, and their findings are increasingly interwoven ...

Spatial clusters of daytime sleepiness and association with nighttime noise levels in a Swiss general population (GeoHypnoLaus)

Stéphane Joost, Idris Guessous, Rebecca Himsl

INTRODUCTION: Daytime sleepiness is highly prevalent in the general adult population and has been linked to an increased risk of workplace and vehicle accidents, lower professional performance and poorer health. Despite the established relationship between ...

Sleep fragmentation alters brain energy metabolism without modifying hippocampal electrophysiological response to novelty exposure

Pierre Magistretti, Jean-Marie Petit, Maxime Olivier Baud

Sleep is viewed as a fundamental restorative function of the brain, but its specific role in neural energy budget remains poorly understood. Sleep deprivation dampens brain energy metabolism and impairs cognitive functions. Intriguingly, sleep fragmentatio ...

Comparison of acute non-visual bright light responses in patients with optic nerve disease, glaucoma and healthy controls

Lorette Leon

This study examined the effect of optic nerve disease, hence retinal ganglion cell loss, on nonvisual functions related to melanopsin signalling. Test subjects were patients with bilateral visual loss and optic atrophy from either hereditary optic neuropat ...

Sustained Sleep Fragmentation Induces Sleep Homeostasis in Mice

Pierre Magistretti, Jean-Marie Petit, Maxime Olivier Baud

Study Objectives: Sleep fragmentation (SF) is an integral feature of sleep apnea and other prevalent sleep disorders. Although the effect of repetitive arousals on cognitive performance is well documented, the effects of long-term SF on electroencephalogra ...

The psychostimulant modafinil enhances gap junctional communication in cortical astrocytes

Pierre Magistretti, Jean-Marie Petit, Joël Gyger, Xinhe Liu

Sleep wake cycle is characterized by changes in neuronal network activity. However, for the last decade there is increasing evidence that neuroglial interaction may play a role in the modulation of sleep homeostasis and that astrocytes have a critical impa ...

Effects of prior light exposure on early evening performance, subjective sleepiness, and hormonal secretion

Jean-Louis Scartezzini, Mirjam Münch, Friedrich Linhart, Apiparn Borisuit

In sighted humans, light intensity, timing, exposure duration, and spectral composition of light are important to entrain the endogenous circadian pacemaker to the 24-h day-night cycle. We tested the impact of two realistic office lighting conditions durin ...

Sleep paralysis in narcolepsy: more than just a motor dissociative phenomenon?

Francesco Manni

Sleep paralyses are viewed as pure motor phenomena featured by a dissociated state in which REM-related muscle atonia coexists with a wakefulness state of full consciousness. We present a 59-year-old man diagnosed with narcolepsy experiencing sleep paralys ...
