Verification of the Effect of a Novel Lighting Source on Circadian Rhythmicity and Mood of Healthy Volunteers

by Admin1 | Sep 2, 2022

Background: In today’s modern society, people spend most of their time in buildings where they are usually exposed to a mere fraction of daylight. This, combined with artificial lighting in the evening, leads to a decrease in the contrast of the photic signal between...

Does the Reduction of Short-Wavelength Light during the Day Impact Human Sleep

by Admin1 | Sep 2, 2022

Background: Light is the main synchronizing factor of the circadian system and provides the adaptation of organisms to rhythmic environmental conditions. Exposure to natural daylight ensures the proper functioning of the body, elevated vigilance during the day and...

Effect of Light Exposure on Serum Melatonin Levels of ICU Patients: A Preliminary Observational Study

by Admin1 | May 16, 2022

Aim: To examine whether the serum melatonin levels in ICU patients are affected by light exposure in the “light” and “dark” parts of the ICU. Method: We measured serum melatonin levels of 10 ICU patients having their bed positioned in the “light part” (artificial and...

Efficacy of light therapy for cancer-related fatigue in (non-) Hodgkin Lymphoma survivors: results of a randomized controlled trial

by Admin1 | Mar 24, 2022

Cancer-related fatigue is one of the most frequently reported symptoms after treatment for (non-)Hodgkin lymphoma. This dissertation describes the procedure and results of the SPARKLE trial which primarily aimed to investigate whether light therapy can be used as a...

Effects of different light incident angles via a head-mounted device on the magnitude of nocturnal melatonin suppression in healthy young subjects

by Admin1 | Jan 21, 2022

Bright light is a primary zeitgeber (synchronizer) for the central circadian pacemaker in humans. Recently, head-mounted devices for light therapy have been developed to treat patients suffering from circadian rhythm sleep disorders. In this study, to evaluate the...
