Sleep Deprivation, Circadian Rhythm Disorders
About this trial
This is an interventional basic science trial for Sleep Deprivation
Eligibility Criteria
Inclusion Criteria: Healthy, no chronic disease Age between 25 - 65 years. Suffer from daytime sleepiness/drowsiness and or a mild mood disturbance (ESS >5 or BDI equal to or higher than 13 but lower than 20, PSQI > 5) Participants will have to have a desk type of work and/or have 3 hours per day between 9:30 am and 12:30 at their office/home in which they could sit in front of the lamp. Exclusion Criteria: Depressive mood (BDI -II > 20) Pregnancy Menopause symptoms Drug use during the last three months known to interfere with sleep, alertness, the biological clock and/or light sensitivity (i.e. regular usage of sleep medication or stimulating substances) Use of immune suppressants. High levels of caffeine intake during a day (5 or more cups, according to https://www.voedingscentrum.nl/encyclopedie/cafeine.aspx#blok7, there are no negative effects expected from 4 caffeine products in normal adults) High alcohol intake (more than 4 for men and more than 3 for women, drinks per day) for more than 5 days in the past month, including binge drinking and heavy drinking according to https://www.niaaa.nih.gov/publications/brochures-and- fact-sheets/alcohol-facts-and-statistics. Participant is not able to refrain from using recreational drugs during the 4 weeks of the study. Shift work schedule in the 3 months prior to participation and/or planned during the 2 weeks of the study Environmental factors in everyday life that may disturb sleep and cannot be prohibited (e.g. young children, noisy environment) Travel over 2 or more time zones in the month prior to participation Travel to sunny holiday locations/wintersports 1 month before participation Personal plans that prevent them for using the intervention during 2 consecutive weeks

No PBM will be emitted from the device; dose: 0 J.cm-2
A PBM high standard dose of 6.5 J.cm-2 with a wavelength of 850 nm, a pulse of 15 Hz and 8 ms and duty factor of 12%
A PBM high dose of 6.5 J.cm-2 with a wavelength of 940 nm, a pulse of 15 Hz and 8 ms and duty factor of 12%
A PBM high dose of 6.5 J.cm-2 with a wavelength of 850 nm, a pulse of 100 Hz and 1.2 ms and duty factor of 12%
A PBM high standard dose of 6.5 J.cm-2 with a wavelength of 850 nm, a pulse of 15 Hz and 8 ms and duty factor of 12%, but in this case the participants will wear filtering googles which will not allow PBM from entering the eyes
