Dim Light

Device

Exposure to dim light with Red-Yellow Re-Timer glasses for 30 minutes in the morning during one week.

Primary outcomes

  1. Study Completion

    Time frame: Baseline

    The percentage of participants recruited that completed the study

Other outcomes

  1. Changes in Quality of Life With theFunctional Assessment of Cancer Therapy - Lung

    Time frame: 5 weeks

    Quality of Life will be assessed before, during, and after the intervention.

  2. Assessment of Environmental Light With Actigraphy (Actiwatch Spectrum Respironics)

    Time frame: 5 weeks

    Exposure to environmental light will be assessed at pre-test, intervention and post-test for a descriptive analysis

  3. Assessement of Chronotype With the Morningness Versus Eveningness Questionnaire

    Time frame: 1 day

    Chronotype will be assessed at baseline for a descriptive analysis.

  4. Change in Fatigue Symptoms With Fatigue Severity Index From Pre-test to Post-test

    Time frame: 5 weeks

    Comparison of fatigue severity from pre-test to post-test.

  5. Change in Sleep Quality With the Pittsburgh Sleep Quality Index From Pre-test to Post-test

    Time frame: 5 Weeks

    Comparison of Sleep Quality from pre-test to post-test.

  6. Changes in Insomnia With Insomnia Severity Index From Pre-test to Post-test

    Time frame: 5 weeks

    Comparison of insomnia from pre-test to post-test.

  7. Change in Circadian Activity Rhythms With Actigraphy From Pre-test to Post-test

    Time frame: 5 weeks

    Circadian Activity Rhythms will be assessed with actigraphy during the 5-week time frame.

  8. Assessment of Visual Acuity With the Snellen Visual Acuity Chart

    Time frame: 5 weeks

    Visual acuity data will be collected and save for safety purposes only at pre-test and post-test.

  9. Assessment of Daytime Sleepiness With the Epworth Sleepiness Scale

    Time frame: 5 weeks

    Daytime Sleepiness will be assessed for safety purposes only at pre-test, intervention and post-test. Individuals with high daytime sleepiness and/or at risk of falling asleep while driving or performing hazardous activities will be referred out to primary care
