    Sammanfattning : Nowadays, people spend 90% of their time indoors, thus creating a healthy indoor environment for occupants is of great importance. Lighting in office spaces is an important aspect when it comes to occupant health and well-being. LÄS MER

  3. 2. An Unrecoverable Sleep Deficit : A literary analysis of Adolescents’ sleep loss and the consequences of sleep deficit regarding academic performance

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Hugo Åhs; [2020]
    Nyckelord :Adolescence; circadian cycle; education; school performance; school start times. NREM; REM; Sleep deficit; Chronotype;

    Sammanfattning : There is a noticeable difference in the debate regarding adolescents’ sleep patterns between the biological clock and society’s clock when we talk about adolescents. Sleep scientists or somnologists, are alarming as more evidence reach the surface that young people are not getting the recommended sleep that is required to perform academically well. LÄS MER

  5. 4. A Demonstration Unit for Human Centric Lighting

    Master-uppsats, Lunds universitet/Innovation

    Författare :Cornelia Cronström; [2018]
    Nyckelord :Human Centric Lighting HCL ; dynamic light; circadian rhythm; melatonin; colour composition; demo lights; Technology and Engineering;

    Sammanfattning : The modern human being is exposed to different kinds of light during a normal day, both natural light and adjusted lighting. The idea that light affects us is uncontested, and so affecting the light in turn becomes a question of well-being. It is often thought that abundant and strong lighting is good lighting, but this is far from always accurate. LÄS MER

  7. 5. The Effect of a Dynamic LED Light Intervention on Sleep Quality of Adolescent Students

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Stina Andersson Eriksson; Karin Wingren; [2016]
    Nyckelord :Sleep quality; Adolescence; Light measurements; Activity tracker; Circadian rhythm; School environment; Keywords: Dynamic LED light; Technology and Engineering;

    Sammanfattning : Objective: Previous studies have revealed positive effects on subjective alertness, performance and general sleep patterns, with exposure to light conditions adapted to time of day according to the circadian system. This study aimed to investigate the impact of a dynamic LED light intervention on sleep quality of adolescent students. LÄS MER
