About this trial

The goal of this clinical trial is to learn if light can enhance the feeling of well-being and sleep quality in Radiographers. It will also find out if there is an optimal recipe for light. The main questions it aims to answer are:

* Will alertness, energy levels, and sleep quality increase in radiographers when the lighting is differed? * What light recipe is the most beneficial for the personnel? Researchers will compare no enhanced light environment to different enhanced light environment to see if the enhanced light is beneficial for radiographers.

Participants will:

* Will work in an enhanced light environment or a non-enhanced light environment * Answer surveys * Take saliva sample

Trial outcomes

Primary outcomes

1

Karolinska Sleepiness Scale (KSS)

To assess the subjective level of sleepiness at a particular time during the day

Time frame
Measurements will be taken three times daily over a period of 16 to 20 weeks, depending on the start date of the inclusion phase, for each period.
2

WHO-5 Well-Being Index

To assess the level of well-being, the WHO-5 Well-Being Index is used. It's a brief, self-reported measure of current mental well-being, consisting of five questions that assess positive mood, vitality, and general interest over the past two weeks.

Time frame
Measurements will be taken at the start and then second Friday in each two-week period over the 16 to 20 weeks (depending on when the inclusion phase can begin) during which inclusion occurs for each season.
3

PROMIS

Patient-Reported Outcomes Measurement Information System (PROMIS) is a standardized, self-reported questionnaire designed to measure an individual's perception of their sleep quality, specifically addressing issues like difficulty falling asleep, staying asleep, and feelings of restlessness. It consists of 8 items that gauge the severity of sleep disturbances over the past seven days.

Time frame
Measurements will be taken at the start and then every Friday in each two-week period over the 16 to 20 weeks (depending on when the inclusion phase can begin) during which inclusion occurs for each season.

Secondary outcomes

Other outcomes

1

Melatonin

Melatonin levels will be measured through saliva samples throughout the day to assess the variations in melatonin.

Time frame
Measurements will be taken on Mondays, Wednesdays, and Fridays each week over the 16 to 20 weeks (depending on when the inclusion phase can begin) during which inclusion takes place for each season.
2

Cortisol

Cortisol levels will be measured through saliva samples throughout the day to assess variations in cortisol values, allowing us to observe, e.g, variations in stress responses.

Time frame
Measurements will be taken on Mondays, Wednesdays, and Fridays each week over the 16 to 20 weeks (depending on when the inclusion phase can begin) during which inclusion takes place for each season.
